In this paper, three phase transmission power system with three different protective schemes such as over current relay, over and under voltage relay and over and under frequency relay is developed using MATLAB/Simulink toolbox. The protective relay is tested for different operating conditions of the transmission power system such as overload, over and under voltage, over and under frequency conditions. Protective relays are explained with simple flowcharts. We used digital logic algorithm for implementation of protective relay. In this paper, a digital multi-function protective relay was designed and implemented on MATLAB/Simulink. In this study we also explore some current techniques ranging from the use of digital logic algorithms to system protection applications. Mother power system protective relays are digital systems based on digital signal processing of power system voltage and current waveforms.
