摘要
本文对6~35kV高压补偿电容柜的控制系统进行优化,在系统发生接地故障时,电容投切前后故障支路的电容电流的特征量变化明显,控制逻辑简洁,方法容易实现,显著提高配电网的接地故障支路查找的准确率。
The control system of 6-30kV high voltage capacitor compensation cabinet is optimized in the grounding fault occurs, the amount of variation of capacitance current of capacitor switching and fault branch obviously, Simple control logic, Method is easy to implement, significantly improve the accuracy of grounding fault branch search distribution network.
