Automatic Voltage Control System Reform Of Thermal Power Plant

In Baotou NO.2 thermal power plant introduce a voltage automatic control system,Composes the AVC system together with the control center,Remote RTU line through the Inner Mongolia regional geological AVC to receive master issued instruction power plant side of 220kV bus。According to Voltage Directive, real-time calculation of the overall objective of the node bus reactive power, At the same time to receive the data units, In accordance with set allocation strategy to optimize the distribution of the generating units of reactive power, And to optimize the results of the non-reactive distributed to the different generators implementing agencies, The output from the implementation of the terminal assigned to the different changes in the magnetic signal generator excitation system, regulation unit reactive power。Taking into account the various sectors of the independence and the new AVC system reliability,After transformation, performed well to achieve the desired purpose.
