Abstract

The reactive power compensation of the converter station is an important means to ensure normal operation of the AC and DC system.In this paper

the reactive power balance of Baoji Converter Station and the mechanism as well as calculation method of the reactive power consumption of the converter valve are studied.The reactive power compensation and system voltage regulation process of the converter station in the current configuration mode of 750 kV shunt reactor

66 kV shunt capacitor

reactance and±500 kV AC filter compensation are analyzed.After switching of the shunt reactance at 66 kV side

the variation of the330 kV and 750 kV bus voltages are simulated and analyzed.Meanwhile

the problems in the switching process of the AC filter in±500 kV DC system are pointed out

and the optimization scheme which is proposed for the existing problems is verified by simulation.
