Abstract

The protection of power systems always attains greater importance; presence of distributed generators (DG’s) in the event of faults, protection engineers has to take utmost focus on it. Most of the traditional practices to design protection relays were electromechanical later replaced with solid state relays, presently both are replaced with digital relays intended better accuracy, high speed and reliable operation of power system protection. In this paper the digital reverse power relay is modeled, simulated to detect the reverse power in the event of faults on MATLAB/Simulink®. Diverse modeling statistics adaptation steps in digitization of a signal are also discussed. Finally, the relay performance is tested on 11kV synchronous generator with presence of microturbine DG connected with 220kV.
