摘要
针对静止同步补偿器(STATCOM)系统,采用并联H桥变流器拓扑结构提高STATCOM装置的补偿容量。同时,对并联H桥直流侧电容进行数学分析,结合交错调制PWM技术,提出一种适合于并联H桥拓扑下STATCOM系统控制策略。研制电压1140V、容量500kvar的STATCOM装置,试验结果证明了该策略的优越性与正确性。
For static synchronous compensator system,the compensation capacity of STATCOM device is improvedby parallel H-bridge converter topologies. This paper analyses the parallel H-bridge DC capacitor mathematical model. At the same time,combined with staggered PWM modulation technique,parallel H-bridge topology of STATCOM system control strategy is proposed. Finally,through building a cascaded STATCOM（ 1140 V,500kvar）experimental prototype,the precision and effectiveness of this strategy are confirmed by experimental results.
