| Abstract: | This paper describes the classification of high-voltage switching controllable shunt reactor of the basic working principle . The device can adjust the system reactive power, suppress over-voltage and frequency arc current, with a continuous smooth power adjustable harmonic current small and the advantages of fast response. Article uses Fourier series decomposition method. This method analyzed about current harmonic content of 300Mvar750 kV controllable high voltage shunt reactor work winding which will put into operation in Hexi 750 kV transmission project Dunhuang substation. Then, according to Hexi 750 kV transmission project planning, analysis of the installation of grading in Dunhuang bus side controllable switching frequency of the system highly resistant to the impact of overvoltage. |
