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。
Considering the need of comprehensive control of high-voltage, large-capacity harmonic rejection and reactive power compensation, considering the best filter effect and minimum economic cost of active power filter, and from the main components of the parameter design, the selection of major equipment And cabling, the realization of the system and other aspects of the parallel structure of the hybrid active filter was studied, forming a set of high-power parallel hybrid active filter design method, and in a smelter 220kV substation Harmonic governance project to be applied, reflecting the good filtering effect and excellent cost performance. The system parameter design method and engineering experience can also be used for other active filter system research and application.
