Abstract
Based on the transient analysis of the compensation capacitor switching, studying the effect of the time of capacitor’s input and removal for grid stability. And based on the stationary solution unchanged, focusing on the general solution of the circuit-order homogeneous linear differential equations and analysis of the effect for the switching current shocks. The results show that the phenomenon of over-current can be avoided. The results of ATP simulation show that, the proposed method can effectively reduce the effect of capacitor switching for grid, improve power quality, and extend the life of the capacitor.
