SPEED CONTROL AND MONITORING SYSTEM FOR SINGLE PHASE INDUCTION MOTOR USING LABVIEW WITH MOTOR PROTECTION

This paper deals with the realization of a proposed system involving the speed control of induction motor and monitoring of its parameters coupled with overload and overcurrent protection. The applications of induction motors are almost too numerous to mention and hence functioning of these machines at proper speed is necessary to ensure good productivity and safety at affordable costs. Monitoring simplifies the outcomes of complex analysis through detailed diagnosis thereby preventing unscheduled downtimes that result in lost production. Speed control is carried out using Direct Torque Control Space Vector Modulation (DTC-SVM) and monitoring is achieved using LabVIEW software. This paper profoundly explains the vector control diagram of SVM as well as the LabVIEW software which generates flexible and scalable design, control and test applications at minimal cost supplemented with overload and overcurrent protection, This proposed system improves the adaptability of prevailing systems.
