基于主动型接地装置消弧控制不同电压反馈方法建模与分析
Modeling and Analysis of Different Voltage Feedback Methods for Arc Suppression Control Based on Active Grounding Device
摘要
Abstract
Due to the lack of detailed modeling and comprehensive analysis of the traditional active grounding device for the active arc suppression control in the distribution network,three implementation methods of feedback voltage control are proposed and compared from multiple perspectives.First,based on the traditional active arc suppression principle,three implementation methods of feedback control are proposed.The transfer function model of the control system is established,and the fault voltage expression is obtained.Secondly,the control system is simplified and analyzed according to the two extreme cases of ground fault.On this basis,three feedback methods are analyzed and compared from four aspects:arc suppression compensation effect,control system stability,influence of control parameters and realization difficulty.Finally,the simulation analysis and the results of the low-voltage experimental platform show that the proposed modeling method and analysis are completely in line with the voltage-based active arc suppression control.It is concluded that the method of feedbacking the fault phase-to-ground voltage has obvious advantages over other feedback methods.关键词
