A Novel Islanding Detection Method for Inverter-Based Distributed Generation Systems
In the area of renewable energy technologies, islanding of distributed generation system needs to be prevented due to safety reasons and to ensure quality of power supplied to the customers.Several islanding detection methods based on passive and active schemes have been proposed in the literature.Passive methods have a large non detection zone(NDZ), While active schemes degrade power quality.This paper proposed a new passive islanding detection method which combines the Wavelet-transform and neural network techniques.This method can reduce the NDZ to zero without any perturbation that deteriorates the power quality.The simulation results show that the proposed islanding detection method is effective and robust in all kind of conditions.
