摘要
在光伏并网发电系统中孤岛效应的检测至关重要,因此研究孤岛效应的检测方法成为光伏发电技术的重要问题。本文简要介绍了孤岛效应检测的概述,分析了AFD检测方法和基于周期扰动的AFDPF检测方法的原理,并基于Matlab软件对两种方法做了相应的仿真研究。研究结果表明了AFD检测方法可基本满足孤岛效应的检测要求,比较AFD检测方法,AFDPF检测方法在检测时间和精度方面都有更好的效果。
It is important to test the islanding effect in photovohaic grid connected power system,therefore re- search on islanding detection method becomes the important issue of photovoltaie power generation technology. This paper briefly introduces the overview of islanding detection,analyzes of the AFD detection method and principle of AFDPF detection method based on periodic disturbance, based on the Matlab software to two kinds of methods to do the corresponding simulation. The results show that the AFD method can basically meet the requirements of islanding detection, compared with AFD detection method, AFDPF detection method has better effect in terms of time and accuracy of the detection results.
