适用于中高压系统的HAPF的研究与应用

The Research of Shunt Hybrid Active Power Filter in High-voltage System

着眼于电力系统对大容量谐波抑制与无功补偿的要求,通过对各种不同结构的并联混合型有源电力滤波器(HAPF)进行比较分析,提出将串联谐振注入式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串联谐振注入式HAPF的应用优势,并详细介绍装置的一般设计方法及其软硬件构成。其中的一些设计思路和工程经验还可推广到其它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。

According to the comparison of a few kinds of hybr/d active power filter（HAPF） with different structure, this paper presents a sort of series resonant HAPF to cancel harmonic and compensate reactive power, which is suitable for applying in high- voltage system. As a example project of harmonic suppression and Var compensation in a copper foil factory, the design method of HAPF is put forward here. The paper focuses on the choice of the HAPF structure and the constitution of system hardware and software. The comparison shows the advantages of series resonant HAPF operating in high - voltage system is low cost and high effect. This method can help to design the other kind of filtering system for High capacity applications,
