Dynamic performance simulink-based for the power differential relay system

This paper describes the details of a Simulink-based dynamic testing of the power differential relay. Power differential relay has been simulated and tested for transmission lines as a MATLAB/SIMULINK model with the use of the Power System Blockset. The developed modeling facilitates testing the dynamic behavior of the power differential relay during fast system transients. Different outputs have been recorded or various operating conditions to visualize the most critical simulation issues such as load angle, active and reactive power difference and power through. The algorithm is implemented and tested for normal operation, system dynamics, and various fault conditions using computer simulator tester. All applied test results confirmed the effectiveness of the developed algorithm.
