ABSTRACT
Modeling tools play a crucial role in both educational and industrial settings, enabling engineers to simulate power systems under various operating conditions, including normal and faulty scenarios. This research focuses on the design of a relay system capable of addressing both over and under frequency conditions. Digital relays exhibit distinct advantages over traditional electromechanical relays, notably in terms of accuracy and response speed. The significance of frequency control cannot be overstated, as significant fluctuations can potentially lead to complete power system blackouts. Historical incidents have demonstrated the severe consequences of frequency instability, often stemming from supply-demand imbalances and unforeseen contingencies. With the rise of distributed generation and the inherent challenges of islanding in modern power systems, the attention of both industrialists and researchers has once again turned to frequency relaying solutions. This study aims to evaluate the performance of the proposed digital frequency relay under diverse system dynamics using simulation tools such as MATLAB/Simulink and microcontroller-based implementations. By conducting rigorous testing and analysis, this research endeavors to contribute to the enhancement of grid stability and the prevention of power system disruptions caused by frequency deviations.
