注入式混合型有源电力滤波器在工程中的应用

着眼于电力系统对大容量谐波抑制与无功补偿的要求,提出了将注入式混合型有源电力滤波器(HAPF)应用于中高压系统,同时结合某铜箔厂大型整流装置谐波抑制和无功补偿的工程实例,从项目成本和治理效果两方面具体分析了注入式HAPF的应用优势.在对该新型有源电力滤波器的参数设计进行研究的基础上,为该铜箔厂研制了一套HAPF装置.最后立足于系统的安全稳定性,对无源滤波器在投运时系统的谐振特性进行了研究,并根据现场不同的工况对注入式HAPF的性能进行了仿真研究.其中的一些设计思路和工程经验还可推广到其他大型滤波和无功补偿装置的设计和应用中,为推进大功率的HAPF的实用化进程提供有益的参考和借鉴.

Application of Hybrid Active Power Filter With Injection Circuit

According to the requirement of harmonic suppression and reactive power compensation in power system, a novel hybrid active power filter(HAPF)with injection circuit is proposed in this paper, which is suitable for applying in high-voltage system. As an example project of harmonic suppression and reactive power compensation in a copper foil factory, the main parameters design method of HAPF is put forward here. The paper focuses on the stability of the power system, so the resonance characteristic of the system when the passive power filter is carried out is discussed particularly. This method can help to design the other kind of filtering system for high capacity applications.
