To date, the question arose about the need to create a system for dispatching power supply to an industrial facility under construction.
And everything would be fine, they hired a company, made a turnkey project, but there are a few BUT:
The construction of the facility does not take place in an open field, but within the framework of the existing infrastructure of the enterprise, i.e. it has its own branched operating power supply system, information computer network, there are ASKUE and the beginnings of a dispatching system for existing energy facilities.
The photo below is an example of the implementation of the mnemonic diagram of the dispatching system on light cubes. LED matrices are used as projectors.
The first step was to create terms of reference for design. Usually, in such cases, they hire an organization that prepares such a technical task (TOR) taking into account the requirements and wishes of the Customer, and then choose design organization. In my case, this task had to be done practically by myself. I will not hide, I collected information through various sources; seminars, consultations with companies and specialists in this area, visits to existing similar facilities, not without the participation of the worldwide network. Here's what happened.
A little about theory. The dispatching system is intended for:
- integrated automated control and management of power supply in normal, emergency and post-emergency modes;
- operational dispatch control and power supply management in real time;
- signaling and operational display of information about abnormal and emergency modes, operation of protections;
- planning and control of electricity consumption of the workshop, technical accounting.
From the many existing names of such systems and based on the required functionality, the name "Automated System for Dispatching Power Supply, Control, Planning and Technical Accounting of Electricity of the Workshop" was born. It was decided to shorten the name to the abbreviation ASU ES ( automated system power management).
The photo below is an example of the implementation of such projects.
The need to create an ACS ES described to achieve the following main goals:
- increasing the efficiency of management, reliability and quality of energy supply;
- reduction of unproductive costs of energy resources;
- providing personnel with information for analysis, optimization and planning of equipment operation and its repair;
- reducing the cost of diagnostics and repair of power equipment.
Characteristics of the object: three 6 kV substations with switchgear cells, several 6/0.4 kV package transformer substations, a fleet of medium and low voltage electric motors.
Since Evolis (Schneider Electric) vacuum circuit breakers were chosen as 6 kV switching devices, relay protection and automation are performed on the basis of digital devices relay protection Sepam series 40, 60 and 80. These devices allow you to implement a supervisory system on them without any problems. There are a number of SCADAs specially tailored for Sepam.
In the next article I will talk about block diagram ACS ES system, which we plan to implement in the project on the basis of the developed technical specifications.
