This paper mainly introduces the fault case of voltage fluctuation caused by SVG high-frequency oscillation in 220 kV PV power station.First of all,the oscillation of SVG and power system account for this fault preliminarily by Analysising the on-site fault recordings.secondly,building the electromagnetic transient model of the whole station of PV and the local grid based on the RTlab simulation platform carries out the fault reproduction,and the results of the simulation reproduction are basically consistent with the fault recordings.lastly,the solution of eliminating the SVG high-frequency negative damping is proposed and and its effectiveness is verified by simulation.This analysis of SVG high-frequency oscillation for renewable energy stations can provide experience and reference for the prevention and treatment of similar faults in the future.
