| 摘 要： | 针对输出滤波器存在的放大网侧电流畸变率、阻尼电阻发热严重的问题,提出一种工程化有源电力滤波器交流侧输出滤波器参数设计方法.采用二阶高通滤波器作为有源电力滤波器输出滤波器拓扑,在综合考虑输出滤波器的开关纹波滤波效果与电流畸变率、电容无功容量、电阻功耗之间关系的基础上,结合理论分析、仿真、实验研究,设计总结了并联有源电力滤波器输出滤波器的参数选择方法.采用该方法为50kVA并联有源电力滤波器设计了一套输出滤波器.实验结果表明:加装输出滤波器后,电流纹波抑制到滤波前的1/4以下,网侧电流畸变率增大约1个点,滤波电阻上90%以上的工频电流被旁路,电阻发热得到有效控制,实验结果验证了该输出滤波器设计方法的有效性.
