摘要

由于现有的正反馈有源频率漂移(AFDPF)孤岛检测算法存在检测时间与总谐波失真(THD)之间的矛盾。本文在分析传统正反馈有源漂移方法的基础上，提出了一种变系数正反馈有源漂移算法。基于MATLAB/SIMULINK建立了主动频率漂移的仿真模型，验证了改进算法的功能。可以看出，该方法不仅有效地检测了孤岛效应，而且减少了盲检测。

An Improved Algorithm of Grid-Connected Inverter for Islanding Detection

As the fact that the existing positive feedback active frequency drift (AFDPF) islanding detection algorithm has contradiction between detection time and total harmonic distortion (THD). In this paper, a variable coefficient positive feedback active frequency drift algorithm is provided, which based on the analysis of traditional positive feedback active frequency drift method. The simulation model of active frequency drift is established based on MATLAB/SIMULINK, to testify the function of improved algorithm. It can be seen that the proposed method not only detected island effect effectively, but also had less blind detection.
