The paper introduces configuration of AVC substation system in Xinhongkou power plant. In view of problem in commissioning and actual operation, the paper investigates problems and the solutions in terms of sampling deviation of AVC master station and substation, tap position of high-voltage auxiliary transformer, allocation strategy of reactive power, communication of AVC and RTU, KVM extender, switching time of AVC to improve the service rate and adjustment qualified rate of AVC. Furthermore, the paper proposes sev-eral operation and maintenance advices for AVC of the similar units.
