摘　　要：统一电能质量调节器(UPQC)能够解决多数电能质量问题,受到国内外电力研究者的广泛关注。对当前UPQC的拓扑结构类型和控制方法进行了综述。一方面,以物理结构为原则从逆变器的功能结构、供电系统方式、装置的系统配置及装置的直流母线电压的提供方式4个方面对UPQC的电路结构进行分类与综述;另一方面,将UPQC的控制部分分为3层:以补偿目标为基础的上层系统级、实施控制目标的中层装置级以及将调制信号产生脉冲的底层器件级,并针对这3层进行综述,最后探讨了UPQC的发展前景及存在的若干问题。As a main solution for power quality problems,unite power quality conditioner(UPQC)is focused by the experts and power system engineers now.This paper emphasizes the structure and control strategy of UPQC.On the one hand,the circuit structure of UPQC is classified and summarized based on the principle of physical structure from four aspects:the functional structure of inverter,the mode of power supply system,the system configuration of the device and the mode of providing DC bus voltage of the device.On the other hand,the control strategy of UPQC is summarized in three layers:the compensation target-based upper system level,the middle device level implementing the control target,and the bottom device level that generates the modulation signal pulse.In the end,the prospect of development in UPQC and some problems are discussed.
