摘要
本文介绍了120kVA并联型有源电力滤波器的研制情况,给出了主电路和控制电路的结构和原理,并对实验中出现的一些问题做出了分析。实验和挂网运行都证明,该装置能有效的补偿电流谐波。由于采用多重化技术,成功的解决了容量和开关频率的矛盾。
This paper introduces a 120kVA parallel active power filter. Not only the structure and principle of main circuit and control circuit are described, but some problems in the experiment are analyzed. The results of both experiment and operation in network have proved the APF can compensate harmonic current effectively. With the multiplex technology, the contradiction between device capacity and switching frequency is solved successfully.
