摘　　要：统一电能质量控制器(UPQC)的一个显著特性是用直流电容器取代直流电源,而直流电容器的电压变化会影响电源的有功功率平衡。为保证UPQC主电路能实时跟踪指令电流的变化进而产生恰当的补偿电流,必须使直流侧电容电压保持恒定。通过采取自适应电压控制器控制直流侧电压的输出来补偿系统损耗,从而保证直流侧电压恒定。利用MATLAB仿真软件对此控制策略进行仿真建模,获得了比较理想的直流侧电压,验证了此方法的有效性。One of the prominent characteristics of Unified Power Quality Controller（ UPQC ） is to use DC capacitor to replace the DC source, and the DC capacitor voltage changes will affect the power active power balance. In order to ensure that UPQC main circuit can real-time track instruction current changes and produce appropriate compensation current and must make DC side capacitor voltage keep constant. By adopting adaptive voltage controller of DC side voltage output to compensate system loss, thus the DC side voltage must ensure constant. Using MATLAB simulation software to control strategy simulation modeling, the ideal DC side voltage has obtained, and verified the efficiency of this method.
