Active Arc Suppression Method for Single-phase Grounding Fault of Power Distribution Network Based on Self-optimized Control
摘要
Abstract
In order to realize active arc suppression for single-phase grounding fault of the non-effective earthed power distribution network and simplify its control method,this paper presents a kind of active voltage arc suppression method for single-phase grounding fault of the power distribution network based on current optimization.This method uses active invertion devices to inject controllable current into the neutral point of the power distribution network.By automatic self-optimizing for injected current and phases as well as combining closed-loop control,it is able to realize optimization on injected current amplitude and phases so as to restrain faulted phase voltage to zero and achieve the aim of arc suppression.Simulating analysis and experimental results indicate that it is not required to measure grounding parameters by using this method which can rapidly restrain faulted phase voltage and realize effective arc suppression for grounding faults of the power distribution network rather than being affected by faulted ground resistance.关键词
