摘要

本文通过Matlab仿真研究现今在配电网不对称系统中无功补偿装置在不同运用场景下（包括:不同的补偿地点、不同的线路长度以及不同的负载大小时）电力电容器投入电网产生的冲击涌流。通过分析得出电力电容器在就近无功补偿时补偿距离越短且所需补偿容量越大时所产生的冲击涌流相对越小。

Abstract

In this paper

the inrush current of power capacitor switching in the power grid when the reactive power compensation device used at different applications

including different compensation location

different length of line and different load

in the asymmetrical system of present distribution network is studied by the Matlab simulation. It is concluded through analysis that when the power capacitor is local reactive power compensation

the shorter the compensation distance is and the larger the compensation capacity is needed

the impact inrush current generated is relatively smaller.
