摘要
该文讨论了一种统一电能质量控制器,分析了其内部的有功功率平衡。在这个基础上提出了一种基于两相同步旋转d-q坐标系的控制方案。在这种控制方案中串联电力有源滤波器被控为电流源使得输入电流为正弦,而并联电力有源滤波器被控为电压源使得负载端为标准正弦电压。最后利用仿真和实验验证了在UPQC中采用这种控制方式的有效性。
A Unified Power Quality Conditioner (UPQC) is presented in this paper. The active power balance of this UPQC is analyzed. Based on the analysis a novel control scheme is established in 2-phase synchronous rotating d-q frame (SRF). In this control scheme the series AF is controlled as a current source and makes the input current sinusoidal, while the shunt AF is controlled as a voltage source and keep the load voltage in the normal value. Simulation and experimental works are done to verify the effectiveness of applying such control strategy in UPQC.
