Simulation Analysis of DC and Switching Impulse Superposition Circuit

摘要：

　　Surge capacitors running between the natural bus and the ground are affected by DC and impulse superposition voltage during operation in the converter station.This paper analyses the simulation aging circuit of surge capacitors by PSCAD electromagnetic transient simulation software.This paper also analyses the effect of the DC voltage to the waveform of the impulse voltage generation.The effect of coupling capacitor to the test voltage waveform is also studied.Testing results prove that the DC voltage has little effect on the waveform of the output of the surge voltage generator,and the value of the coupling capacitor has little effect on the voltage waveform of the sample.Simulation results show that surge capacitor DC and impulse superimposed aging test is feasible.
