摘要
将并联H桥变流器拓扑应用于静止同步补偿器(STATCOM)系统,有效改善了装置的补偿容量,重点对H桥直流侧电容进行分析与选型。结合直接电流控制技术,提出一种适合于并联型H桥拓扑下STATCOM系统控制,对电网电能质量进行优化。最后,搭建额定电压/容量(1.14 kV/500 kvar)试验平台,试验证明了该策略的正确性和有效性,并得到了较好的补偿效果。
The parallel H-bridge converter topology is used to static synchronous compensator(STATCOM) system, it effectively improves the compensation capacity of the device.This paper focuses on analysis and selection of the H-bridge DC side capacitance.Combined with direct current control technology,a suitable H-bridge topology for STATCOM system control is presented.Power quality is optimized.Finally, rated voltage/capacity (1.14 kV/500 kvar) test platform is built.The test proves the correctness and effectiveness of the strategy and gets a better compensation effect.
