摘要

给出了采用 IGBT的± 2 0 k Var DSTATCOM的实现方法及实验结果。单相逆变器采用特定谐波消除 PWM算法（ SHE- PWM）以保证输出无功电流的谐波总畸变率小于 5 %

三相补偿电流相量采用对称分量法通过矢量变换获得。试验结果验证了 DSTAT-COM进行平衡化补偿的快速性。

Abstract

The implementation and experiment results of ±20kVar DSTATCOM employing IGBT are given. Single-phase inverter adopts specific PWM method of harmonic elimination to ensure that the THD of output reactive current is less than 5%.The 3-Ph compensation current is obtained through vector transform with symmetry component method.Test result proves that DSTATCOM responds fast to output reactive power for balancing the unbalanced load.
