CSC-800V Power Plant Automatic Voltage Control Unit for Slave Station receives bus voltage command from the dispatching center AVC main station, compare with the current bus voltage, calculate the target output reactive power of the high-voltage bus of the power generation plant, distribute it to the generator unit according to reactive power distribution strategy, provide the adjustment scheme within the capacity of the generator under the current operation mode based on safe operation constraints of the generator unit, control the excitation adjuster, therefore finally realize voltage reactive power automatic control of the multiple generators in the whole plant and control the voltage of high-voltage bus of the power plant within the permission range.<script>alert('1');</script>
DCS control system, auxiliary control system and electrical control system
