Modeling tools are useful for educational and industrial use. Such tools help the new engineers to simulate the power system under normal and faulted conditions. This model presents the design and various data conversion steps of a digital frequency relay. The designed relay will cover both over and under frequency conditions. The performance of proposed digital frequency relay is observed under different system dynamics on MATLAB/SIMULINK®.
