Research of Photovoltaic Grid Connected Power System Islanding Effect Detection

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.
