摘要
本文详细分析了统一电能质量控制器的工作原理、数学模型及在两相同步旋转坐标系(SRF)中的控制系统。通过采用所提出的控制策略 UPQC 可以在电网电压有谐波、输出带非线性负载的情况下实现功率因数为1的正弦电流输入、负载端电压为与电网电压同相的额定正弦电压。
The author in this paper analyzed in detail the operation principle,mathematical modes and its control manner inSynchronous Reference Frame(SRF)of a Unified Power Quality Conditioner(UPQC).Taking up the proposed control strategy,UPQC can carry out all of the control goals,such as to input sinusoidal current with cos(?)=1 and to output rated sinusoidal voltage onthe load-side with the same phase as source voltage in the case of the network voltage would be with harmonic and the outputtingwould be to non-linear load.
