摘要/Abstract

摘要： 孤岛检测的方法很多,尤其是主动式孤岛检测方法。如何在众多的主动孤岛检测法中选择最合适的方法是应用中的难点。针对主动法中的应用较多的滑模频率偏移法和有源频率偏移法,分别对其检测盲区、检测速度、对电能质量影响进行机理分析。理论分析结果表明在盲区相同时,SMS(Slip-Mode Frequency Shift)法造成的逆变电流总谐波含量更小,但SMS法的检测速度在不同参数条件下存在较大区别。在Matlab/Simulink中对孤岛检测方法进行建模,实验结果证明了理论分析的正确性。

关键词: 滑模频率偏移法, 有源频率偏移法, 检测盲区, 电能质量, 检测速度

Abstract: There are many islanding detection methods, especially the active islanding detection method. It is difficult to choose the best method among so many active islanding detection methods in practice. In this paper, the non-detection zone (NDZ), detection speed and their effect to power quality of slide-mode frequency shift (SMS) method and active frequency drift (AFD) were researched. The results show that SMS is superior to AFD at the aspect of the effect on power quality when they have same NDZ. While the detection speed of SMS has big difference under different parameters. The Islanding detection model was built on Matlab/Simulink. The experimental results show the correctness of theoretical analysis.

Key words: SMS, AFD, NDZ, power quality, detection speed
