光伏并网发电系统中孤岛现象的研究

本文主要对光伏并网发电系统中的孤岛效应进行了研究,并对反孤岛效应的方法进行分析,提出主动频率偏移法和双向频率的主动频率偏移法,并进行了比较和实验验证,实验结果表明,双向频率的主动频率偏移法更能缩小孤岛效应检测盲区并提高检测的速度。

this paper mainly for photovoltaic （pv） grid generation system of island effect are studied, and the method of inverse island effect, the article analyzes the active frequency offset method and two--way frequency of active frequency offset method, and compares them and experiment, the experimental results show that the active two--way frequency carrier frequency offset method can more narrow island effect detection and improve the speed of blind detection.
