电力系统中要求电压稳定度和无功功率满足一定的技术指标，利用带独立直流电源的级 联式多电平逆变器和多电平逆变器最优化谐波台阶式调制技术(OHSW)设计的STATCOM装置， 可以使电力系统中的电压得到稳定以及无功功率和谐波得到有效补偿。本文主要介绍了STAT- COM装置主电路的设计，主电路是STATCOM装置与系统进行交换有功功率与无功功率的环节。 该装置具有输出谐波含量低、损耗小、性能可靠等优点。(Requirements of power system voltage stability and reactive power to meet certain technical specifications, the use of DC power supply with independent level Joint multi-level inverter and multi-level inverter optimized harmonic stepped modulation (OHSW) design of the STATCOM device, Can make the power system voltage stability and reactive power to be harmonic and effective compensation. This paper describes the STAT- COM device main circuit design, is the STATCOM main circuit switching devices and systems for active and reactive power component. The device has a low output harmonic content, low loss, performance, and reliable.)
