Abstract:

The isolated function and incomplete monitoring scope of current electrical control systems in gas distributed energy stations have brought great inconvenience to operators. In order to solve the problems above, improve integration level of electrical control system, and facilitate the unified control and management for operators, an integrated design of a new electrical control system for gas distributed energy station is proposed. The system is composed of power distribution and sales control subsystem, power generation control subsystem, auxiliary power control subsystem, stepup substation control subsystem and telecontrol communication control subsystem. These subsystems are all connected to double Ethernet and clock synchronization bus through communication management unit. The system realizes the integration of  power generation and sales, which makes the operation of distributed energy station more flexible, efficient and economic.
