摘要

基于合理假设建立电流补偿平衡方程和功率平衡方程

分析总结出了△形和Y形H桥链式静止同步补偿器(STATCOM)补偿负序电流的条件

推导出零序分量控制是链式STATCOM补偿负序电流的关键

该结论得到了MATLAB/Simulink仿真软件的有效验证。所提出的分析方法还可进一步推广至其他拓扑及不同工况下的STATCOM。

Abstract

Based on rational assumptions

current compensation balancing equations and power balancing equations are established. The conditions for negative sequence compensation static synchronous compensator (STATCOM) in △-type and Y-type H-bridge cascade topologies are analyzed. The conclusion that control of zero sequence components is the key to unbalanced current compensation for STATCOM in cascade topologies is proved by simulations with MATLAB/Simulink. The analysis method presented can be generalized to STATCOMs under different working conditions in other topologies. This work is supported by Jiangsu Provincial Natural Science Foundation of China (No. BK20140118) and State Grid Corporation of China (No. GWKJ20140087).
