Islanding detection strategy for multiple distributed generations
(UMT.Lahore, 2020) Muhammad Furqan
Islanding is the condition in the distributed generator (DG) in which the network becomes disconnected from the main grid and the system still energized the islanded network. Islanding operation has been an unwanted process because it is harmful to the environment and personnel, as well as damages the load connections and harms the network equipment. Therefore, it was important to identify the islanded operation by using multiple distributed generation in the power system. In this research, a new technique has been proposed to detect the islanded condition. In the proposed technique two DG units, main bus bar voltage, and wind farms power generation are used. Simulation results have been obtained under different islanded and non-islanded conditions by using MATLAB. The proposed algorithm proves to be efficient and has no non-detection zone (NDZ). This passive technique is best because the algorithm is easy to implement. Keywords: Islanding, Islanding operation, Distributed generation (DG), Non-detection zone (NDZ) and Matlab.
