Realizing the laboratory model for reverse power protection of alternator interfaced with GSM

Generators is one of the most important, delicate and costlier components of power system. Since power plant generators are very important part of an electrical energy network, so they should be protected in order to maintain the quality and reliability of power supply. This paper presents the design and implementation of reverse power protection of alternator during the failure of prime mover. Initially the system has been designed by using MATLAB Simulink for synchronous generator and then further implemented in laboratory with the of real time system using reverse power relay interfaced with GSM. The complete analysis of motoring protection system has been constructed on software as well as in hardware and various results have been obtained for the different conditions of prime mover failure.
