摘　　要：含蓄电池的统一电能质量控制器(UPQC)采用最小能量法对电能质量进行补偿,可以有效降低有功功率的输出,延长补偿的时间。然而UPQC在进入补偿和退出补偿会造成负载电压发生波动,影响负荷的安全用电。为此,提出了一种UPQC最小能量平滑补偿的控制策略,通过平滑控制UPQC的进入补偿过程和退出补偿过程,防止负载电压出现波动。通过Matlab/Simulink平台进行仿真验证,仿真结果表明UPQC在投入和退出时刻,负载电压幅值出现了小幅波动,但其波动的范围未超过国家标准。The unified power quality controller(UPQC)containing battery uses minimum energy method to compensate power quality,which can effectively reduce the output of active power and extend the compensa⁃tion time.However,UPQC will,in case of putting in and out of compensation,cause fluctuation of load voltage and affect safe power consumption of load.Therefore,a kind of control strategy of minimum energy smoothing compensation for UPQC is proposed,which can prevent fluctuation of load voltage through smooth control of UPQC input and exit process.The simulation verification is performed by Matlab/Simulink platform and the simulation result shows that,in case of the time of in and out operation of the UPQC,the amplitude of the load voltage has small fluctuation,but its fluctuation range is within the the national standard requirement.
