This paper presents an application of Programmable Logic Controller (PLC) for power factor improvement of a 3-phase induction motor. The implementation incorporates development of the hardware and software for power factor improvement of a 3-phase squirrel-cage induction motor. The hardware comprises of power-circuit and control-circuit equipped with protective devices whereas software includes PLC program developed under the IEC-61131-3 standards. The process includes switching of capacitor-banks through digital output of the PLC in a proper logic. The addition of capacitors to the motor circuit introduces capacitive reactance into the system circuit. This capacitive reactance offered to the motor equivalent circuit compensates the inductive reactance of the motor and thereby, improves the power factor of the system. |
