Protection of Electrical Equipment Against High Power Supply Using FOPID-PR: A Comparative Study with FOPID and PR Controllers

Abstract

Electrical devices are prone to deterioration as a result of over-supply of power, resulting in reduced performance and higher maintenance needs. This work presents a Fractional Order Proportional-Integral-Derivative with Proportional Resonant (FOPID-PR) controller, proposed to improve regulation of power and reduce harmonic distortion. The controller adjusts voltage levels dynamically with changes in power to provide effective power management with system stability. Comparison with standard FOPID and PR controllers is presented, with emphasis on Total Harmonic Distortion (THD) suppression and system performance under changing power levels. Detection using voltage changes with high-power and low-power is also investigated to check the effectiveness of the controller. Simulation outcomes reveal that the FOPID-PR controller functions much better than traditional methods with improved voltage stability, effective power management, and THD attenuation. This makes it a potential solution for protection of electrical devices from disturbances of the power supply and for the improvement of power quality as a whole.
