| 摘 要： | 分析了50kVA并联有源电力滤波器(Shunt Active Power Filter,简称SAPF)基于同步坐标变换的直流侧电压控制模型,并基于控制模型设计出直流侧电压环的PI调节器.为了避免启动时直流侧电压的过冲,采用分3个不同阶段的启动方法完成了直流侧电压的软启动.采用设计的PI调节器来控制SAPF投入运行后的直流侧电压.控制仿真和实验结果均证明了理论分析的正确性和可行性.

| Abstract: | A DC capacitor voltage control model of 50kVA Shunt Active Power Filter(SAPF) is analyzed,and the PI controller of DC voltage control loop is designed based on the model.In order to suppress the surge voltage,the method of soft startup of DC voltage which constitutes of three stages is presented.The aforementioned PI controller is adopted to control DC voltage after putting into operation of shunt active power filter.The experimental and simulative results from a 50kVA prototype confirmed the feasibility of the proposed approach. |
