摘要

针对链式STATCOM直流电容电压不平衡的现象

提出了一种基于脉宽充电面积控制的均压方法。该算法循环控制链节极值电压

使得极大值和极小值电压链节循环工作在最小充电面积脉宽和最大充电面积脉宽下。该算法控制简单、易于实现

仿真试验结果证明了其有效性。

Abstract

In this paper

as for the imbalance circumstance of DC capacitor voltage of STATCOM

a balancing method based on the control of pulse width charging area is proposed. In this algorithm

the links extreme voltage is controlled so to keep the Max. and Min. voltage link operate at minimum and maximum charging area pulse width. The algorithm control is simple and easy to achieve. And the efficiency is verified by the simulation test result.
