摘　　要：对一种大容量复合电流质量调节装置进行了深入研究,基于模块化的思想,提出一种新型的主电路拓扑结构,主电路由基波补偿模块和谐波补偿模块组成,基波模块由多个H桥组成链式结构,用以提高基波补偿容量,减小输出电压谐波含量;谐波模块由单个H桥构成,其交流侧跨接在基波连接电感两端,可以减小谐波模块的电压等级和容量。给出了装置的控制策略,该控制策略实现了无功功率和谐波电流的解耦控制和补偿。最后通过仿真与实验结果证明了提出的主电路结构及控制方法的有效性。A deep study on high-capacity composite current quality conditioner is performed. Based on the think of modularization, a new topological structure of main circuit, which composes of fundamental compensation modules and harmonic compensation modules, for the conditioner is proposed. Fundamental modules compose of multiple H-bridges to form chain structure to increase fundamental compensation capacity and reduce harmonic content in output voltage; harmonic compensation module composes of single H-bridge and its AC side is parallelly connected to both ends of fundamental inductor to reduce voltage class and capacity of harmonic modules. Control strategy of composite current quality conditioner, which implements decoupling control and compensation of both reactive power and harmonic currents, is given. Results of simulation and experiments show that the proposed main circuit and control strategy are effective.
