摘　　要：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。The electric power system requires that voltage stability degree and reactive power satisfied some certain technology parameter. Using cascade multilevel inverters with separated DC source and Optimized Harmonic Stepped-Waveform (OHSW) technology designed the STATCOM equipment. The equipment which can let voltage stabilization as well as compensate reactive power and harmonic. This thesis introduced the systemic power circuit structure of STATCOM briefly , and the structure of the main circuit is a Chunnel for exchanging active power and reactive power between STATCOM and system. The equipment has three advantages, such as low harmonic output, small wastage and credibility capability.
