Abstract

This paper deals with unified power quality conditioner (UPQC), which aims at the integration of series-active and shunt-active power filters. The main purpose of a UPQC is to compensate for voltage imbalance, reactive power, negative-sequence current and harmonics. This paper discusses the compensation principle and control strategy of the UPQC in detail. Experimental results obtained from a laboratory prototype of 20 kVA are shown to verify the viability and effectiveness of the UPQC.

统一电能质量调节器(UPQC):原理、控制和应用
统一电能质量调节器(UPQC)是一种将串有源和并联有源电力滤波器集成在一起的调节器。UPQC的主要目的是补偿电压不平衡、无功功率、负序电流和谐波。本文详细讨论了UPQC的补偿原理和控制策略。在20 kVA的实验室样机上获得的实验结果验证了UPQC的可行性和有效性。
