Wi-Fi based Speed Control of Three Phase Induction Motor using PLC and SCADA

Three phase induction motor are widely used motor in industry because of its rugged construction and negligible maintenance. To operate this kind of motor, star-Delta starters are used. But, because of its constant speed characteristics many times it is driven with the help of Drive to have reliable operation its performance must be monitored continuously. Design and Fabrication of monitoring and control system for 3 phase induction motor based on Programmable Logic Controller (PLC) technology. Also implementation of a hardware and software for protection and speed control with the result obtained from the test on three phase induction motor performance is provided. The PLC correlates the operational parameters to protect motor and monitor the system during normal operational and under trip condition. Other performance parameters of three phase induction motor can also be monitored by other control devices. AC drives (or VFD) can also use to control motor rotation direction and rotation speed of three phase induction motor. All the required control or protection and motor performance data will be taken to personal computer via PLC for further analysis. Speed control from control side and protection from performance side will be priority. The monitoring, Supervisory Control and Data Acquisition of three phase induction motor done by SCADA software. The personal computer and PLC are connected by Wi-Fi.
