Abstract :
In this paper the performance of a new hybrid islanding detection method is studied considering a synchronous generator based wind power system. The proposed hybrid islanding detection algorithm combines an adaptive reactive power perturbation based active method with a novel passive algorithm. The passive algorithm considered in this study relies on some special transient response characteristics of the islanded system for providing an islanding suspicion signal. On receiving the suspicion signal the active counterpart injects minimum reactive power based on the resonant frequency to detect the islanding condition. The performance of the developed method is analyzed with various case studies conducted in MATLAB/SIMPOWERSYSTEMS environment.
