摘　　要：电动汽车充电会带来诸如电压波动、谐波增多、三相不平衡加剧等一系列电能质量问题。提出了统一电能质量调节器(UPQC)应用方案,在UPQC建模分析基础上,基于两相静止坐标系推导设计了电压控制单元双PI闭环控制器和电流控制单元带状态反馈单闭环PI控制器,并推导出PI参数整定依据;为给样机设计提供理论参考,基于数学模型,推导出UPQC各模块参数设计依据,并设计与研制了1台20 kW容量的UPQC样机进行了实验研究。实测波形表明:UPQC的应用可改善电动汽车充电设备的电能质量。Electric vehicle charging brings a series of power quality problems including vohage fluctuation, harmonic increase and phase imbalance. An application scheme of Unified Power Quality Controller （UPQC） is put forward to solve these problems. Based on mathemalieal model of UPQC in two-phase stationary axis, w^ltage control unit based on dual P1 loop controller and eun＇ent control unit with state feedback single loop Pl controller are designed. PI parameter settings are determined based on eomroller Iransfer function. A 20 kW prototype of UPQC is dewdoped based on proposed research results. The experiment results show that the application of UPQC can improve power quality of electric vehicle charging equipment.
