摘　　要：静止同步补偿器(STATCOM)因具有无功补偿响应速度快、连续调节范围宽等优点,已经现代电力系统中重要的补偿设备之一。对不同控制策略STATCOM的补偿效果进行研究是该领域值得关注的关键问题。在此对STATCOM主电路进行四重化的结构优化,有效降低谐波含量,控制策略上采用电流间接控制方法,在Matlab/Simulink平台上实现了补偿系统的建模和仿真,通过比较补偿前后系统功率因数的变化,验证了所采用控制策略的正确性和有效性。STATCOM（static synchronous compensator） for reactive power compensation with fast response and wide continuous adjustment range has become one of the important compensation devices in modern power system.The study on compensation effects of STATCOM with different control modes is an important work which should be paid more attention.QMR structural optimization for STATCOM main circuit is performed to efficiently reduce the harmonic content.A method to indirectly control the current is adopted.The modeling and simulation of the compensation system were realized on Matlab/Simulink platform.The correctness and validity of the control mode mentioned above were verified by comparing the variations of the system power factors before and after compensation.
