| 摘 要： | 针对传统p-q法存在的问题，提出了一种以p-q理论为基础，通过空间矢量变换使畸变电压达到理想电压的改进型p-q法。在畸变电压（受谐波污染且三相不平衡）条件下利用三相四线制四桥臂有源滤波器进行谐波抑制和无功补偿，并与传统的p-q法进行了比较，MATLAB仿真结果表明，改进型p-q法具有更好的滤波效果。

| Abstract: | According to the traditional p-q theory had many problems, the improved p-q method is studied in this paper. The distorted voltage is transformed to ideal voltage through the space vector. Harmonic suppression and reactive power compensation are finished under the distorted voltage by use of three-phase four-wire four-leg active filter. Comparing to the traditional p-q theory, the simulation results show this method is effective. |
