Analysis of micro-grid based fault transient and its supression
摘要
Abstract
An equivalent analysis model for micro-grid with inductive FCLs is presented based on Matlab-simulink. The fault transient characteristics of the micro-grid are analyzed, and the new scheme of using FCL to suppress the transient process is thereby verified. With regard to different fault types and different fault locations under various operation modes, the transient recovery behavior of the micro-grid system with inductive FCLs, such as variation of voltage, current, frequency, active and reacitive power, is investigated in detail. The research results show that the micro-grid with inductive FCLs can achieve a new steady state much faster than that without FCLs at any operating conditions. The research proposes an effective methodology to suppress the fault transient process for micro-grids.
