针对现存的混合型有源滤波器的无源滤波部分只是对一种谐波情况设计的,对变化的信号不能改变滤波形式、当电网波动时有源滤波部分的压力增加等问题进行了改进,其创新点是引入可控可调式的补偿电路结构,可以针对变化的电网情况改变补偿的网络结构,而不是仅仅改变同一网络的参数,对电网达到跟踪补偿的效果,它对电网谐波污染和无功损耗均有很好的抑制和补偿作用,必定会在实际应用中得到广泛的发展。
The passive filter part of the existing hybrid active filter is only designed for one kind of harmonic condition. The changing form of the filter can not be changed and the pressure of the active filter part increases when the power system fluctuates. The innovation is to introduce a controllable and adjustable compensating circuit structure, which can change the compensated network structure according to the changing grid conditions, instead of merely changing the parameters of the same network and achieving the effect of tracking compensation on the grid, Reactive power loss are very good inhibition and compensation, will certainly be widely used in practical applications.
