Introduction

"Rules technical operation diesel power plants" determine the procedure for organizing the operation of equipment, heat engineering and cable communications of diesel power plants (DPP).
The rules apply to stationary DPPs owned by the Ministry of Fuel and Energy of the Russian Federation with a capacity of 500 kW and above.
The rules do not apply to reserve and mobile diesel power plants.
The need to develop these Rules arose due to the fact that those issued in 1989 do not apply to diesel power plants.
However, given that many provisions of these Rules are applicable to diesel power plants, for the convenience of using the document, some provisions of the PTE of power plants and networks are repeated in these Rules.
Requirements for design, construction, installation, repair and installation power plants in these Rules are set out very briefly, since they are considered in the current NTD. These include:
- "Norms process design diesel power plants. NTPD-90";
- ;
- ;
- Construction norms and rules (SNiP);
- State standards of the USSR;
- "Guidelines in terms of process measurements, signaling and automatic regulation at thermal power plants. RD 34.35.101-88".

Trouble-free and trouble-free operation of the power plant is possible only under the condition of a clear and uninterrupted functioning of all its components and systems. Maintenance personnel must clearly understand the principle of operation of the installed equipment, control and signaling circuits, automation and control units, as well as design features, layout and interconnection of individual equipment elements. Only specialists who have studied and mastered the technical documentation for the installed equipment, its material part, and who know the operating conditions of this equipment can be allowed to service the DPP.

If a diesel power plant is served by two teams - electricians and diesel operators, then both teams, having perfectly studied the units and systems entrusted to them directly, should have an idea about the operation of all the equipment of the diesel power plant as a whole.

Persons serving diesel power plants must pass a special commission to test their knowledge of the rules for the technical operation of electrical installations, safety precautions and fire safety, operating instructions, the technical minimum for the equipment to be maintained and methods of first aid in case of accidents.

To obtain practical skills in maintenance and a more detailed acquaintance on the spot with the location and condition of the equipment, each employee servicing the diesel power plant must undergo an internship at the workplace lasting at least two weeks under the guidance of a more experienced employee; after that he is allowed to independent work. Persons servicing the diesel power plant are subject to periodic testing of knowledge of the rules of technical operation and safety. The listed requirements for the operating personnel make it possible to ensure reliable, safe and rational operation of the diesel power plant.

2. PREPARATION OF POWER PLANTS FOR OPERATION

Before start-up, the diesel power plant must be carefully checked and prepared for operation. It is necessary to inspect the diesel engine, generator, auxiliary units, panels and shields and eliminate the detected malfunctions. Using a 500 V megger, check the insulation resistance of the unit circuit with the switches on; resistance must be at least 0.5 MΩ.

If the insulation resistance of the generator and the rest of the circuit is below 0.5 MΩ, dust, wipe or dry exposed electrical insulating parts; if necessary, dry the generator. When preparing the diesel power plant for operation, it is necessary to check the degree of discharge of the batteries and correct the ignition systems. Starting a diesel engine with a starter when the batteries are discharged more than 50% is not allowed.

The service fuel tank must be filled with fuel and the fuel tank valve in the open position. The fuel level in the supply tank is controlled by the fuel level indicator. A fully filled service tank ensures continuous operation of the generating set for at least 4 hours.

It is necessary to make sure that there is no air in the fuel system, fill the service and additional oil tanks, and also fill the internal circuit of the cooling system with water (if any) and check the water circulation in the external circuit of the cooling system.

There should be no leaks in the fuel supply, lubrication and cooling systems of the diesel engine. If necessary, tighten the sealing nuts, clamps and clamps.

Before starting, check the tightness of all air cleaner connections and the air lock mechanism.

The position of the switches and switches on the panels, control panels of the generator and diesel automatics must comply with the operating instructions for the DPP.

The mains generator circuit breaker must be open and the control circuit switch must be set to Manual Override or Auto Magic Start.

After carrying out these operations, the DPP electric unit is considered prepared for start-up and operation.

3. START-UP, OBSERVATION OF THE OPERATION OF POWER PLANTS AND THEIR SHUTDOWN

Starting and stopping the diesel power plant can be manual - from the local diesel control panel, remote - from the remote control remote control or automatic - without the intervention of maintenance personnel on an automation signal when changing control parameters in the network or on another unit.

Manual start and stop are made in accordance with the factory instructions. After starting and warming up the diesel engine at idle, its speed is gradually brought to the maximum. Then the generator is excited and the current frequency is set to 50 Hz using the frequency meter by changing the diesel engine speed. By turning the resistance knob of the voltage setting on the voltmeter, the rated voltage of the generator is set, after which the generator machine and the load to the generator are turned on. After start-up, the normal operation of the water and oil cooling systems is checked.

To stop the diesel power plant, it is necessary to turn off the automatic generator switch (unload), reduce the voltage on the generator and reduce the diesel engine speed. The diesel engine runs at idle, followed by a slow decrease in speed until it stops completely.

Remote automatic start and stop are made from the remote control or control cabinet using control buttons. All operations for starting and stopping the generating set are carried out in a given technological sequence by the automation circuit.

In the event of a successful start, the signal lamp lights up Normal operation; if an emergency mode occurs, then an alarm or protection is triggered and the DPP is automatically stopped.

Automatic start and stop are carried out in a certain technological sequence without the intervention of personnel by the automation circuit.

The signal for automatic start is a change in the control parameters of the redundant electric unit: an unacceptable decrease or increase in voltage, an overload of the electric unit, an unacceptable decrease in the voltage of the industrial network.

The signal for automatic shutdown is a reduction in the total load of two parallel generating sets (main and standby) to 80% of the rated power or restoration of voltage in a controlled industrial network.

Automatic shutdown of the generating set occurs when emergency conditions occur and alarm and protection sensors are triggered. The inclusion of DPP generators for parallel operation is carried out in accordance with the recommendations.

Supervision of the operation of the diesel power plant in normal operating conditions.

During diesel operation it is necessary:

  • monitor the readings of diesel operation control devices (oil and water temperature, oil pressure, etc.), the presence of coolant in the system, oil supply to diesel parts and the operation of various diesel sensors;
  • replenish fuel tanks in time; pay attention to the presence of extraneous noise or knocks in the diesel engine;
  • in the absence of automation, monitor the engine speed and, if necessary, adjust it. When servicing the generator, you must: monitor the readings of ammeters, voltmeters, wattmeters. Exceeding the nominal values ​​is unacceptable. Unsymmetrical loading up to. 25% of rated current and current overload not more than 10% for 1 hour;
  • control the temperature and noise of the bearings. The temperature of the bearings is controlled by touch by hand (or a thermometer) by the temperature of the covers in accessible places and should not exceed 80 ° C. The noise of the bearings should be heard through a special wooden rail. One end of the rail must be attached to the ear, and the other to the hub or other part of the end shield. If the bearings are in good condition, a uniform rumble is heard without knocks and shocks;
  • check the vibration of the generator by touch. If the vibration is greater than normal, it is measured with a vibrometer in the radial direction vertically and horizontally. The double vibration amplitude of the generator when working with a diesel engine, measured on end shields, should not exceed 0.2 mm or the data given in the instructions for the generator;
  • adjust the voltage and frequency within the nominal values;
  • observe the indications of insulation monitoring devices, emergency and warning signals: if necessary, take measures to eliminate abnormal modes;
  • periodically monitor the operation of the brush apparatus of the exciter and slip rings of the rotor;
  • evenly distribute the load (in the absence of automation) between parallel generators;
  • periodically listen to the generator for the absence of knocks and extraneous noise;
  • in the event of a sudden disappearance of the readings of one of the stator or rotor devices, check with other devices whether this is the result of damage to the device itself, supply chains, etc.

If the device or the supply circuit is damaged, then, without changing the operating mode of the generator, it is necessary to take measures to eliminate the malfunction.

Standby power plants provide uninterrupted power supply to agricultural consumers. They are installed, as a rule, directly at consumers of categories I and II. The industry produces standby power plants and units with carburetor and diesel engines. With capacities over 16 kW, the use of diesel power plants is economically justified.

The main element of stationary and mobile backup power plants is a diesel generator. The primary diesel engine and the synchronous generator are interconnected by a rigid coupling. Power plants are equipped with equipment and instrumentation for controlling and monitoring their work.

Stationary diesel-electric units up to 200 kW are supplied complete. They are designed for indoor operation at ambient temperature from +8 to +40°С.

A mobile power plant is a complete electrical installation mounted on vehicles and protected from atmospheric influences. It is designed to work outdoors at temperatures from -50 to +40°C. The design of the power plant allows you to move it to any distance without compromising readiness for work.

Depending on the purpose of the diesel unit and the specific conditions of its operation state standard There are three levels of automation.

First degree(lowest) maintains the desired speed, coolant temperature and lubricating oil; provides alarm and protection; at the request of the customer, it performs recharging of storage batteries and, if necessary, replenishment of supply tanks with fuel.

Second degree provides control of diesel-electric units during start-up, operation and stop for at least 16 hours for units with a power of up to 100 kW and at least 24 hours for units with a power of more than 100 kW.

In addition, the following should be automatically performed: start on command from an automatic device or remotely; preparation for receiving the load, receiving the load or issuing a signal about readiness for receiving the load (in parallel operation); load acceptance with synchronization, remote control of the unit speed at manual entry into synchronism; stop on command from an automatic device or from a distance; keeping the idle engine warm.

Third degree provides control of a diesel-electric unit for 150 hours for units with a power of up to 100 kW and at least 240 hours for units with a power of more than 100 kW. Additionally, the following operations are performed: filling fuel, oil and liquid tanks, air cylinders; recharging of batteries, distribution of specified active and reactive loads during parallel operation; control of auxiliary units providing automatic operation for 240 hours.



Diesel-electric units, automated in the second and third stages, must have an alarm and protection when limit values ​​are reached: coolant temperature, lubricating oil temperature, lubricating oil pressure, pressure, flow or liquid level in closed loop cooling, speed, reverse current or reverse power.

Backup stations generate electrical energy of alternating three-phase current with a voltage of 230 and 400 V at an industrial frequency of 50 Hz. In this case, all consumers of electricity are connected directly to the tires of the voltage generator. This guarantees high stability of the voltage quality, the deviations from the nominal voltage for generators of diesel stations with machine exciters and coal-fired regulators of the RUN type do not exceed ± 3-5% when the load changes in the range from 0 to 100%, for self-excited synchronous generators in the absence of voltage correction on generator ± 3-5%, and in the presence of voltage correction ± 1-2%. The voltage deviation of synchronous generators supplying power, lighting and household loads should be within +5 to -5% of the nominal.

Diesel units of stations must allow 100% overload for 1 hour. The largest deviation of the rotational speed when turning on and off the rated load is 6%.

Mobile power plants have a number of devices for their transportation: emergency coasting and parking brake, tow hook latch, rear light, brake light, control drive mobile wheels etc. Before transporting mobile diesel power plants, the reliable operation of these devices, as well as the strength of fastening units and auxiliary equipment, should be checked.

In preparation for work mobile power plant, you must first select the place of its installation, which must be flat and horizontal, not have nearby (4 ... 6 m) buildings and structures, located in the center of the location of electricity consumers. To create good cooling conditions, the DPP generator is installed against the direction of the wind, while the unit hood doors on the generator side must be open. After installation, the mobile power plant is fixed with a hand brake, and when working for more than 2 ... 3 days, its springs and wheels are unloaded with jacks. When preparing a mobile diesel power plant for operation, it is also necessary to install a protective ground and attach the generator case to it, place and connect lighting equipment, deploy a cable network, and inspect all nodes.

Acceptance mounted DES is carried out in accordance with the requirements of SNiP. In this case, the following delivery documentation is required: an act on the need for inspection (revision) of the unit with disassembly; the protocol of inspection (revision) of the diesel generator (if it was carried out); form of installation of the generator or the entire unit; the act of readiness of the foundation for the installation of a diesel generator; protocol for checking the possibility of turning on the generator without drying.

After presenting the necessary documentation, the customer, with the participation of representatives of the installation and commissioning organizations, conducts a comprehensive test at idle, draws up an act of putting the power plant into operation.

Starting the generating set. Before start-up, it must be carefully checked and prepared for operation. In this case, it is necessary to inspect the engine, generator, auxiliary units, panels and shields, eliminate the detected malfunctions. The insulation resistance of the unit circuit with the machines turned on must be at least 0.5 MΩ. At lower insulation resistance values, all insulating parts are cleaned of dust and dirt, and, if necessary, the generator is dried. Before starting, it is also necessary to check the degree of rarefaction of the batteries, the serviceability of the ignition system. Starting the engine with a starter is not allowed if the batteries are discharged by more than 50%.

The service fuel tank must be filled, its valve is set to the position "Open". The fuel level in the supply tank is controlled by the fuel level indicator. It is necessary to make sure that there is no air in the fuel system, fill the service and additional oil tanks, and also pour water into the internal circuit of the cooling system, check the air circulation in the external circuit of the cooling system. Before starting, check the tightness of all connections of the air cleaner and the air damper mechanism.

The position of the switches and switches on the panels, control panels of the generator and diesel automatics must comply with the operating instructions for the DPP. Before starting the station, the automatic generator circuit breaker in the power network must be turned off, and the control circuit switch must be set to the position "Manual control" or "Auto start".

Manual start and stop is carried out in accordance with the factory instructions. After starting and warming up the engine for 10 minutes at idle, its speed is gradually brought to the nominal, then the generator is excited. With the help of a shunt rheostat, the rated voltage of the generator is set (according to a voltmeter), the generator is turned on, which gradually takes the load up to 75% of the nominal. After start-up, the operation of the water and oil cooling systems is checked; if there are no comments, after 15 minutes the load is increased to the nominal value.

To stop the generator, it is unloaded by disconnecting the load. Then, gradually increasing the resistance in the excitation circuit, turning the handle of the shunt rheostat counterclockwise lowers the generator voltage to the lowest value and stops it.

Remote automatic start and stop is performed - from the control panel or control cabinet using buttons. All operations for starting and stopping the generating set are carried out in a given technological sequence, provided for by the automation scheme.

In the event of a successful start, the signal lamp lights up. "Normal work"; if an emergency mode occurs, then the protection is activated, the signal board lights up "Emergency Work" and the unit will automatically stop.

The signal for automatic start is the change in the control parameters of the redundant electric unit: unacceptable voltage drop, overload, etc. The signal for the automatic stop of one of the parallel units is the reduction of the total load on the generator voltage buses to 80% of the rated power or when the voltage is restored in the controlled network. In this case, the backup unit is switched off. Automatic emergency stop of the generating set occurs when emergency conditions occur and alarm and protection sensors are triggered.

Diesel engine operation. During operation, it is necessary to monitor the readings of control devices (oil temperature and water, oil pressure, etc.), the presence of coolant in the system, the supply of oil to the rotating parts of the diesel engine and the operation of various sensors. It is necessary at least 2 times per shift to check the amount of oil in lubricators, as well as in bearings with ring lubrication. If necessary:

Add oil;

Replenish fuel tanks in time; at least once per shift, drain settled water and dirt from consumable fuel tanks;

Pay attention to the presence of extraneous noise or knocks in the engine;

Clean fuel filters, oil filters at least once a quarter low pressure should be cleaned in accordance with the manufacturer's instructions;

Monitor the engine speed and, if necessary, adjust it (in the absence of automation - systematically).

When operating the generator, you must:

Monitor the readings of ammeters, voltmeters, wattmeters (load unbalance is allowed no more than 25% of the rated stator current, and overcurrent no more than 10% for 1 hour);

Control the temperature of the active steel and the generator windings, which should not exceed the temperature environment more than 65°C; control the temperature of the bearings (its excess over the ambient temperature is permissible by no more than 45 ° C);

Periodically monitor the operation of the brush apparatus of the exciter and slip rings of the rotor;

Evenly distribute the load (in the absence of automation) between parallel generators;

Observe the indications of insulation monitoring devices, emergency and warning signals; if necessary, take measures to eliminate abnormal modes;

Check the degree of vibration of the generator. During the operation of the diesel power plant, it is necessary to inspect the shields and panels of the auxiliary generator, excitation equipment and power electrical equipment.

Periodic check readiness of the standby unit for start-up. It is carried out once every 2-3 months. At the same time, the status and operation of automation equipment are checked. A preventive scheduled inspection of the generator and the pathogen is carried out after 500 hours of operation, but at least once every six months. During a scheduled inspection of the generator, they check the condition of the working surface of the collector, the correct fit of the brushes to the collector and their placement, the degree of suitability of the oil for further operation, the condition and reliability of contacts with the network.

After 100-150 hours of operation, but at least once every six months, after long stops (more than 20 days), the insulation resistance of the stator, rotor and exciter windings is checked. The condition of the exciter and generator bearings is judged by the noise during operation and by the heating temperature. It should not exceed 80°C. To prolong the service life of bearings, every 500 hours, but at least once every six months, check the condition of the lubricant in them.

At least once every six months, the switching connections and equipment inside the switchboard of the power plant are inspected. At the next inspection, they wipe off the dust, check the tightness of the contacts and other joints of the tires and wires. At the same time, fuse-links and signal lamps are replaced as necessary. All loose contacts are tightened, and the places of contact connections with traces of burning and oxidation are cleaned, tinned, etc.

The control and signaling circuits of power circuit breakers, ATS and synchronization circuits must be checked after cleaning and revision of the equipment. The operation of protection elements (thermal and electromagnetic releases, relay current protection) is checked once a year for reliable operation and for compliance with the settings to design values. Circuit breakers are checked element by element by primary current. Electrical measuring equipment is checked at least once every two years and, as a rule, timed to coincide with current or major repairs.

Periodicity, volume and norms preventive overhaul tests are established taking into account a comprehensive assessment of the condition of each generator, their design features, subject to the following requirements:

Interrepair tests are carried out no later than three years after the overhaul or previous preventive tests. Rejection of these tests
allowed if the frequency of major repairs does not exceed four years;

The scope of overhaul tests includes a mandatory test of the stator winding insulation with increased voltage at a frequency of 50 Hz or with rectified voltage;

Reducing the test voltage compared to that applied during the last overhaul is allowed by no more than 0.2 U n voltage with a frequency of 50 Hz and no more than 0.5 U H rectified voltage;

Preventive overhaul testing of the winding insulation is carried out in addition to the tests and measurements carried out during the current repair of the generator.

Before testing the stator and rotor windings of the generator with increased voltage, it is necessary to measure the insulation resistance. The insulation resistance of the stator windings is not standardized, it must be compared and contrasted with the readings of previous measurements. The insulation resistance of the rotor winding must be at least 0.5 MΩ, excitation circuits - 1 MΩ, armature windings and its bandages - 0.5 MΩ.

The stator winding of a generator with a power of up to 1000 kW and a voltage of up to 1000 V is tested with an increased AC voltage of industrial frequency equal to 1.6U H +800 V, but not less than 1200 V, for 1 min immediately after the generator stops. The rotor winding during operation with increased voltage is not tested.

During preventive tests, the DC resistance of the stator, rotor and exciter windings is measured. These measurements make it possible to identify various winding damages during major and current repairs. If the resistance of the winding of any phase of the stator differs from the resistance of the windings of other phases (or previously measured) under the same (or given) temperature conditions by more than 2%, then this will be the result of short circuits or poor-quality soldering in the frontal parts of the winding. The DC resistance value of the rotor and excitation windings should not differ from the previously measured value by more than 2%.

In addition to those described, the following checks and preventive tests of generators are carried out: testing of windings and active steel for heating; determination of reactances; electric strength testing of slip rings, field extinguishing machine; measurement of the residual voltage of the generator after its shutdown; detection of coil short circuits in the rotor winding; identification of admissible asymmetric regimes.

Current and capital scheduled preventive repairs of reserve power plants are carried out with the following frequency: current repairs for mobile power plants operating in the open air, every six months, for stationary ones - annually, overhaul for mobile DPPs - at least once every four years, stationary DPPs - as needed, but at least once every five years.

If you want your diesel generator to serve you faithfully for many years, justifying the funds spent on its purchase, you must follow all the rules for its operation. Yes, a commonplace phrase, but there are still many unpleasant incidents associated with the breakdown of diesel power plants, which could have been avoided by knowing the appropriate rules for operating diesel generators.

It is important to understand that the trouble-free and trouble-free operation of a diesel power plant is possible only if all its components and systems work in a coordinated manner. And only specialists who have thoroughly studied the operation manual and technical documentation of the diesel generator can be allowed to service the diesel installation. The operating personnel must be familiar with the principle of operation of the power plant, design features, control and automation units, as well as a clear understanding of the relationship of all elements of a diesel power plant.

Those involved in the maintenance of diesel generators must pass a commission on knowledge of fire safety rules, operating instructions and safety regulations. For maintenance of diesel power plants, it is necessary to have overalls and personal protective equipment.

Inclusion

Before starting the diesel generator, it is necessary to carefully inspect the equipment, including auxiliary units, panels and shields. The instruction manual for diesel generators implies the elimination of all identified malfunctions. Using a megohmmeter with the switches on, check the insulation resistance, which must be at least 0.5 mΩ. When this indicator is below the established norm, it is necessary to do the following: dry the insulation parts, wipe them, and clean them of dust. As indicated in the instruction manual for diesel generators, you need to check the ignition system and the charge level of the batteries.

Remember, the fuel tank valve must be in the "open" position, and the diesel generator tank itself must be filled with diesel fuel. It does not hurt to make sure that there is no air in the fuel system. Now we turn to filling the internal cooling circuit with water (antifreeze, antifreeze) and check the circulation of the liquid in the external circuit.

Check the equipment carefully, there should be no leaks in the cooling, lubrication and fuel supply systems in the diesel power plant. The rules for the operation of diesel generators in this case provide for tightening the clamps, sealing clamps and nuts.

Immediately before starting the diesel generator, check the tightness of the air cleaner connections and make sure that the air damper mechanism is tight. Both start and stop of diesel generators can be automatic, manual or remote.

What is important to know when operating diesel generators

  • Before starting the diesel power plant, it is imperative to carry out an external inspection for the presence of any foreign objects on the moving parts. If the moving parts are not open and protected by a casing, then you should make sure that there are no leaks and cracks in the systems that are part of the diesel generator.
  • Carry out timely preventive cleaning of equipment from dirt, dust and leaking oil, which is necessary to prevent engine overheating.
  • For proper and trouble-free operation of a diesel generator, regular oil changes are required. As a rule, replacement is carried out depending on the operating time of the diesel engine, and a complete replacement is carried out only after 1000 hours of operation of the unit.
  • Control the oil level in the oil tank and the speed controller for a more stable operation of the diesel power plant. The allowable rate of oil leakage during operation is 100 g per 100 hours of operation of the unit.
  • It is not recommended to start a diesel drive from a cold state. Therefore, before starting the diesel generator, it is necessary to warm up the oil; for this, special electric oil heaters are used. The norm is an oil temperature of 30-35 degrees. Special heaters are either built in at the factory or installed manually.
  • Do not attempt to repair any malfunction of the diesel generator yourself, which can only worsen the technical condition of the equipment. Seek help from qualified professionals only.
  • Running a diesel generator without load for more than 30 minutes can lead to rapid wear of parts, keep this in mind.
  • The drawdown of the crankshaft in the crankcase of a diesel engine can be determined by the position of the clutch. If it is slightly below the initial position, then the rotor drawdown has already reached its critical position. The diesel power plant will work at the same time, but peddling, that is, destroying its thrust bearings.
  • It is necessary to ensure that the total number of consumers in no case exceeds the maximum permissible power of the generator, which will cause an overload and shutdown of the diesel generator.
  • Keep in mind that a diesel generator gradually fails during long periods of inactivity, because the flexibility of some elements of the system is impaired. To avoid breakdowns, at least once a month, the generator should be turned on for at least one hour.

If you want to buy a diesel generator, then be sure to study all the main points outlined above. By listening to the advice and adhering to the rules for operating diesel power plants, you can avoid unnecessary breakdowns and waste of money. It is also important to keep these rules in mind if diesel generator rentals are used, as in this case your knowledge will protect against possible problems when operating leased diesel generators.

Introduction

"Rules for the technical operation of diesel power plants" determine the procedure for organizing the operation of equipment, heat engineering and cable communications of diesel power plants (DPP).

The rules apply to stationary DPPs owned by the Ministry of Fuel and Energy of the Russian Federation with a capacity of 500 kW and above.

The rules do not apply to reserve and mobile diesel power plants.

The need to develop these Rules arose due to the fact that the Rules for the Technical Operation of Power Plants and Networks, published in 1989, do not apply to diesel power plants.

However, given that many provisions of these Rules are applicable to diesel power plants, for the convenience of using the document, some provisions of the PTE of power plants and networks are repeated in these Rules.

The requirements for the design, construction, installation, repair and installation of power plants in these Rules are set out very briefly, since they are considered in the current NTD. These include:

- “Norms for technological design of diesel power plants. NTPD-90”;

1.1.1. The main task of diesel power plants (DPP) is the production, distribution and supply of electrical energy and heat (in the presence of utilization), the implementation of the dispatch schedule.

1.1.2. The power plants operated by the power system, equipped with internal combustion engines, are organized in structural units acting on the basis of the "Regulations on the structural unit (enterprise) on the basis of cost accounting".

1.1.3. When several power plants work together, dispatch services should be created to control and regulate their operating modes.

1.1.4. The main duties of DES employees:

Compliance with the specified conditions of energy supply to consumers;

Maintaining the normal quality of the supplied energy - the normalized frequency and voltage of the electric current;

Compliance with operational and dispatching discipline;

Ensuring maximum efficiency and reliability of energy production;

Compliance with the requirements of explosion and fire safety during the operation of the equipment;

Compliance with occupational health and safety requirements;

Reducing the harmful effects of production on people and the environment.

1.1.5. At each power plant, by order of the head, the functions for servicing equipment, buildings, structures and communications between responsible persons from among the engineers should be distributed.

1.2. Commissioning of equipment and facilities

1.2.1. Completely completed diesel power plants, as well as, depending on the complexity, their queues and start-up complexes must be put into operation in the manner prescribed by the current rules. This requirement also applies to the commissioning of stations after expansion, reconstruction, technical re-equipment.
