大功率并联混合型有源滤波器的参数设计与应用研究

Design and Application of High-Capacity Shunt Hybrid Active Power Filter

综合高电压、大容量谐波抑制兼无功补偿综合治理的需要,从有源滤波器的最佳滤波效果和最小经济成本两个角度考虑,并从主要组成部分的参数设计、主要设备的选取与布线、系统的工程实现等方面对采用注入式结构的并联混合型有源滤波器进行了研究,形成了一整套大功率并联混合型有源滤波器的设计方法,并在某冶炼厂220kV变电站谐波治理工程中得以应用,体现出良好的滤波效果和优异的性价比。该系统的参数设计方法与工程实现经验还可以用于其它有源滤波系统的研究与应用。

According to the integrated requirements of harmonic elimination and reactive power compensation, the paper considers better filter performances arrd less cost of active power filter, and then forms a whole set of design methods for high-capacity injection type shunt hybrid active power filter. Its application in a smelt plant＇s 220kV substation can meet the harmonic suppression requirement well and the effect is obvious between high performances and low cost. To date China has few applications of high-capacity shunt hybrid active power filter till now, so the given parameter design method and engineering experience are useful for applications and research of other active power filter.
