摘要
三电平静止同步补偿器(STATCOM)在配电网无功补偿领域发挥重要的作用。在不考虑系统有功损耗的情况下,对三电平STATCOM在基频调制方式下的电压和电流进行了理论分析,给出了相应的解析表达式。利用Matlab/Simulink对三电平STATCOM的瞬时有功功率和无功功率变化情况以及电压和电流波形进行了仿真分析。仿真结果表明所提出的电压和电流理论分析方法是正确、有效的,可推广应用于其他类似结构的电力电子电路的理论分析与仿真研究中。
The three-level STATCOM （static synchronous compensator） plays important role in the reactive power compensation of the distribution system. Assuming that the STATCOM has no active power losses, the current and voltage analytical expressions of the three-level STATCOM under the fundamental frequency modulation （FFM） control were presented by using the theoretical analysis method. Meanwhile, the current, voltage, active power, and reactive power waveforms are simulated and analyzed with the help of Matlab/ Simulink. Simulation results verify the validity of the theoretical method, which can be extended to the analysis of similar power electronic circuits.
