光伏并网发电系统孤岛检测的研究

摘要

孤岛检测是光伏发电系统必需的功能,既要快速的检测出孤岛效应,同时也要减少不良的影响。本文分析有源孤岛检测方法和无源孤岛检测方法的工作原理,论述每种方法的检测盲区,适用范围以及对系统电能质量的影响。%Islanding detection is a necessary function of PV systems.It is necessary to quickly detect islanding,but also to reduce the adverse effects.It analyzes active and passive islanding detection methods and the working principles.It discusses blind detection,scope and power quality of the system of each principle.
