摘　　要：统一电能质量调节器 ( UPQC)是结合串联有源滤波器和并联有源滤波器的一种新型谐波和无功补偿装置。文中分析了它的系统结构和工作原理 ,并根据提出的检测控制方法研制了一台实验样机 ,进行了实验研究。实验结果表明 ,样机不仅可以补偿非线性负载产生的无功电流和谐波电流 。The unified power quality conditioner (UPQC) is a kind of novel harmonic and reactive compensation equipment by combining the series active filter and shunt active filter. This paper discusses its system configuration and working principles. Then a prototype is developed according to the detecting and control strategy proposed. The experimental results show that it can not only compensate for the reactive and harmonic current caused by the nonlinear load and negative sequence component of the source voltage, but also regulate the amplitude of the load voltage.
