摘　　要：提出统一电能质量控制器(Unified Power Quality Controller,UPQC)串并联换流单元共同协调控制无功功率的策略,该控制策略简化了电压矢量计算方法,引入了闭环控制使得串联换流器承担理想的无功功率,利用UPQC串联换流单元的容量补偿无功功率扩大了UPQC整体无功运行范围,解决了容量利用率低的问题,仿真验证了该方法的有效性。The control strategy for reactive power compensation is proposed for Unified Power Quality Controller（UPQC）,which is jointly coordinated by series converter and parallel converter.The voltage vector calculation method of this control strategy is simplified.The closed loop control is introduced to make the series inverter for ideal reactive power.The control strategy utilizes the capacity of series converter to compensate reactive power,and expands the overall operating range of UPQC,which solves the problem of low capacity utilization.The simulation verifies the validity of this method.
