he generator is demagnetized.
The requirements for plant power system control are:
Supply power to the plant load through the start/standby switch when the unit starts up; During the normal power consumption of the unit, the auxiliary machines necessary to start the unit are supplied by the plant transformer and the low voltage plant transformer to the low voltage load of 400VMCC; When the plant power disappears, in order to protect the safety of equipment and system, the plant power quick cutting device should quickly and automatically switch the plant work load to start/standby switch; When the bus of the security section is confirmed to be out of voltage, the emergency standby diesel engine should be started to supply power to ensure the safety of the equipment.
According to the above control level requirements, electrical monitoring into DCS technology requirements are:
(1) The generator system can realize program control and soft hand control to make the generator from zero lift speed, boost voltage until the grid connection belt initial load.
(2) The plant power system can be implemented according to the requirements of program control and soft hand operation in the start/stop stage and normal operation stage.
(3) It can display and record all kinds of data and states under the normal operation, abnormal operation and accident state of the above generation and change group system and the power plant system in real time, and provide operation guidance
