摘要

静止无功发生器（static var generation

SVG）由于具有无功功率补偿、稳定电压的作用

在配电网获得了大量应用。为解决SVG运行时产生的高次谐波

一般采用LCL滤波器进行滤除。LCL滤波器的引入对SVG补偿的动静态特性产生影响。因此

本文提出了一种针对SVG的无源性控制方法

可以和改善SVG运行时的动静态特性

基于PSCAD的仿真验证了所提策略的有效性。

Abstract

Static var generator（SVG） has found wide application in the distribution network thanks to its function in reactive power compensation and voltage stabilization.For solving the high-order harmonics generated by SVG in operation

LCL filter is generally used for filtering.The introduction of LCL filter affects the dynamic and static characteristics of SVG compensation.Therefore

a kind of a passive control method for SVG is proposed in this paper

which can improve the dynamic and static characteristics of SVG in operation.The effectiveness of the proposed strategy is verified by PSCAD-based simulation.
