ensure that only one unit of DCS to achieve the control of the common part, while another unit of DCS can achieve real-time monitoring, And this operation control can be switched.
(4) The interlocking logic of the electrical system is simple, but the operating mechanism of the electrical equipment itself is complex.
Therefore, the electrical system of the unit into DCS control, control system has high reliability requirements. In addition to realizing normal start-stop and operation operation, it is especially required to realize real-time display of various data and states under abnormal operation and accident state, and provide corresponding operation guidance and emergency treatment measures to ensure the automatic control of electrical system in the most safe and reasonable working conditions.
The electrical system shall be included in the scope of DCS monitoring
According to the operation of the unit and the characteristics of electrical control, in the application of the project will be used in the generator – transformer group and plant power supply and other electrical system control are included in the 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
