DCS monitoring.
All the electrical systems in the main plant from the booster station (excluding the booster station) to the power plant side are included in the DCS monitoring. The main systems are summarized as follows:
Generation group system (excluding the ventilation system of the transformer itself);
Generator excitation system;
High voltage factory power supply system (including normal switching of factory power supply);
Low voltage factory power supply system and 400VPC;
High voltage start/backup power supply system (shared by 2 machines);
Diesel generator set and security power supply (monitoring only);
Dc system and UPS system (monitoring only);
Automatic synchronous system;
Power plant quick cutting system.
Electrical main protection safety automatic device because of the requirements of DCS to achieve its function is still a certain degree of difficulty, and to increase considerable cost. In principle, DCS is not required to achieve its functions, still retain its device, but they should have an interface between DCS, conventional way to use a hard interface. The reserved protection automatic special devices are mainly as follows:
Change group protection device;
Automatic quasi-synchronous device (ASS);
Automatic voltage adjusting device (AVR);
Plant power quick cutting device;
Fault recording device.
The electrical systems of auxiliary systems outside the main plant, such as coal transport, water treatment, hydrogen production and
