Abstract :

This paper presents an active islanding detection technique are using hysteresis current controlled inverter. This paper are also refer single inverter as well as multiple inverter for single phase grid. Islanding occurs when a portion of distributed power system becomes electrically isolated from the rest of the power system yet continues to be energized by distributed generators. In this method, all such occurrences are needed to be detected as early as possible in order to safely shut down the distributed generators. So the simple and fast responses the current controlled inverter circuit is to disconnect all distributed generators immediately after the occurrence of islands. Typically, a distributed generator should be disconnected within 100 to 300 ms after loss of main supply. Each distributed generator must be equipped with an islanding detection device which is also called anti islanding devices. An active islanding detection technique is proposed for grid connected single phase hysteresis current controlled inverters. Active method are better at sensing islanding disturbances and reducing or eliminating the Non Detection Zones (NDZs). Feasibility of the proposed technique is performing by MATLAB Simulink.
