谐振注入式有源滤波器的输出滤波器研究

输出滤波器作为有源滤波装置（APF）的重要组成部分，对整个系统的滤波效果有着不可忽略的影响，目前APF的研究对这方面的探讨较少。文章以谐振注入式结构的APF为例，结合已有的工程经验，从稳态和动态两个方面探讨输出滤波器对整个系统性能的影响，以此为基础，综合考虑系统的谐波输出能力、高频滤波效果、动态性能以及逆变器直流侧电压，提出运用多目标遗传算法进行输出滤波器参数的优化设计。实例设计表明，与根据经验设计的参数相比，经优化设计的输出滤波器能够更好的满足整个系统的要求。

The Output Filter Research of Resonance Injection Active Power Filter

As the important part of active power filter (APF), the output filter influences the effect of the whole system. However few papers focused on it. As the example of resonance injection APF, this paper probes into the effect of the output filter from the steady and dynamic state by using the project experience. Based on the harmonic filtering capacity、output ability、dynamic performance and direct voltage, a multi-objective genetic algorithm is put forward to optimize the design of the output filter parameters. The example result shows that the output filter designed by optimization method can meet the requirement of the whole harmonic canceling system better than the ones designed just by experience.
