摘要
Abstract
Islanding detection is one of the important problems of distributed photovoltaic power generation,which guarantees the security and stability of the entirety power system.Most of the previous detection methods always have an inefficient detection,and cost a long time.To solve these problems,an improved active phase-shift islanding detection method was proposed,and the principle and analysis of improved method were unfolded.The parameter of improved method was set automatically due to the change condition of frequency and voltage at the point of common coupling and it took a fuzzy control to the rate of frequency change and frequency variation when the islanding occured.Simulation results based on Matlab/Simulink indicate that the improved method has increased the detection efficacy,shorten the time and has a low influence to power quality,which has practical reference value for application.关键词
