摘　　要：介绍了STATCOM拓扑展开原理,根据STATCOM装置的性能考虑开关频率和误动作等对STATCOM进行拓扑建模,展开成4个拓扑区间进行谐波分析。利用Matlab软件编写程序求出STATCOM的输出电流以及直流侧电容电压,并画出波形。同时由得出的输出电流作为输入源进行FFT变换得到输出电流的幅频特性,结果表明含有较大的3次和5次谐波,为实际工程应用提供参考。The principle of STATCOM topology is introduced in this paper. According to the perfor- mance of STATCOM device, we should consider the impact of switching frequency and misopera- tion on topology modeling of STATCOM, it is expanded to four topology intervals for harmon- ic analysis. The STATCOM output current and DC side capacitor voltage are obtained by using Matlab, and its waveform is drawn. At the same time, we carry on FFT transformation to STAT- COM output current as the input source for obtain the amplitude frequency characteristics of it. The results show that it contains 3 times and 5 times larger harmonic. This paper provides some reference for actual engineering.
