Technical assignment to electricians for dispatching. Terms of reference for the development of working documentation

To date, the question has arisen about the need to create a power supply dispatching system for an industrial facility under construction.

And everything would be fine, hired a company, made a turnkey project, but there are several BUT:

The construction of the facility is not taking place in an open field, but within the existing infrastructure of the enterprise, i.e. it has its own ramified operating power supply system, an information computer network, there is an ASKUE and the rudiments 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, an organization is hired that prepares such a technical assignment (TOR), taking into account the requirements and wishes of the Customer, and then they choose design organization... In my case, I had to do such a task practically myself. I will not hide, I collected information through various sources; seminars, consultations with firms 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 the theory. The dispatching system is designed 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 prompt display of information about abnormal and emergency modes, operation of protections;
  • planning and control of electricity consumption of the shop, 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 metering of workshop electricity" was born. It was decided to shorten the name to the abbreviation ACS ES ( automated system power management).

The photo below is an example of the implementation of such projects.

He described the need to create an ACS ES in order to achieve the following main goals:

  • improving the efficiency of management, reliability and quality of power supply;
  • reduction of unproductive energy consumption;
  • 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 facility: three 6 kV substations with switchgear cells, several 6 / 0.4 kV transformer substations, a fleet of medium and low voltage electric motors.

Since Evolis (Schneider Electric) vacuum switches were chosen as 6 kV switching devices, the relay protection and automation is based on Sepam series 40, 60 and 80 digital relay protection devices. These devices allow you to implement a dispatching system on them without any problems. There are a number of SCADA systems specially tailored for Sepam.

In the next article I will talk about structural diagram ACS ES system, which we plan to implement in the project based on the developed technical specifications.
