Abstract: The use of microcontroller technology has enabled the design of energy efficient and cost-effective reliable control systems for induction motors. This study presents a PIC microcontroller-based control system for the protection of a three-phase induction motor. Fault types of induction motor like phase failure, unbalanced voltage, locked rotor, under voltage, overvoltage and more are considered in this work. Fault monitoring and diagnosis are performed using artificial neural network. Fault classification is achieved through the microcontroller which includes a program for fault classification. When a fault occurs, the microcontroller sends a signal to the interfaced digital relay to trip the motor circuit and another signal to an LCD to display the type of fault. The use of the microcontroller reduces the response time of the protection system and makes it more suitable for real time operation. The proposed protection scheme is simulated using Matlab Simulink. Matlab simulation results show that the well trained ANN scheme is able to detect all types of internal faults at different locations. The microcontroller used in this work is the high performance enhanced flash PIC18F4520 of microchip which has an on chip analog to digital converter peripheral, among other features. The microcontroller is programmed using ‘C’ and assembly language to control the function of the digital relay. MPLAB Integrated Development Environment (IDE) is applied for the development of the proposed embedded applications.
