应用诺顿等效模型的APF并网交互影响分析
Analysis on Interactions Among Grid-connected APFs Using Norton Equivalent Model
摘要
Abstract
The interactions among multiple active power filters(APFs)may emerge when they are connected to grid si?multaneously,which will deteriorate the control performance of one single APF or even lead to system instability.In this paper,a method is proposed to analyze the dynamic interactions among multiple APFs in weak power network.Norton equivalent principle is used to establish a mathematical model of one single APF and that of multiple grid-connected APFs further.Moreover,relative gain array(RGA)principle is adopted to analyze the negative interactions among mul?tiple APFs.In the meantime,through the study on the effect of changing circuit parameters and controller parameters on the negative interactions,a strategy of weakening and eliminating the negative interactions is proposed based on the se?lection and combination of parameters.Simulation results in time domain show that the proposed method and its corre?sponding solving strategy are feasible and effective.关键词
