摘　　要：此处首先分析了统一电能质量调节器(UPQC)的工作原理和多种类型的拓扑结构,并提出一种左串右并型UPQC可接入三相三线或三相四线系统中并可以实现串并联侧的电能质量调节。随后对UPQC的控制策略进行了分析,选用了无需检测电源电压及负载电流的扰动畸变等信息的间接补偿控制策略,其中串联逆变器被控制为受控电压源,并联逆变器被控制为受控电流源。最后对UPQC进行仿真与实验验证,从结果论证了此装置和控制策略的可行性。Firstly,the working principle and various types of topologies of unified power quality conditioner(UPQC)is analyzed,and proposes a kind of left series right parallel UPQC which can be connected to three-phase three-wire or threephase four-wire system and can realize the power quality regulation of series parallel side.Then,the control strat-egy of UPQC is analyzed,and the indirect compensation control strategy without detecting the disturbance and distor-tion of power supply voltage and load current is selected.The series inverter is controlled as the controlled voltage source,and the parallel inverter is controlled as the controlled current source.Finally,the UPQC is verified by simula-tion and experiment,and the feasibility of the device and control strategy is demonstrated from the results.
