并联型有源电力滤波器对电动机和电容器谐波源补偿特性的研究

Research on Compensation Characteristics of Shunt Active Power Filter to Motor and Capacitor Harmonic Sources

在分析感应电动机和电容器谐波源阻抗特性的基础上,推导出了在谐波环境下电动机和电容器谐波源的阻抗计算公式、序阻抗和序导纳矩阵。通过研究并联型有源电力滤波器对感应电动机和并联电容器谐波源的补偿特性,得出了并联型有源电力滤波器适宜补偿电感性谐波源、不适宜补偿电容性谐波源的结论。实验结果验证了该结论的正确性。

Starting from analyzing the impedance characteristics of the inductor motor and the capacitance harmonic source, this paper derives a formula for calculation impedance, sequence impedance and sequence admittance matrix on account of the harmonic sources. Besides, it is pointed out that the parallel active power filter is suitable for the inductance harmonic sources, and not for the capacitance harmonic sources. Experiment result shows the correctness of this conclusion.
