Fault detection and Induction motor safety using Programmable Logic Controller and Supervisory Control and Data Acquisition system

Aiming at high accuracy and time consumption in classical method by eliminating the mechanical components, this work focuses on an automation process for fault detection and Induction motor safety using PLC and SCADA. The software of the system uses RS Logix 500 English to construct a ladder logic program and In-touch to design the operation process taking place in Induction motor. The communication between these two software is achieved by Dynamic Data Exchange. The problems such as voltages, currents, over speed, vibration alert and temperature sensing values of the Induction motor are monitored. By communicating the Programmable Logic Controller (PLC) to Supervisory Control and Data Acquisition System (SCADA) the warning messages are displayed on the computer screen. This PLC and SCADA system based protection method provides a visual environment to analyze and rectify the faults occurring in a three phase induction motor comparing to a Programmable Integrated Circuit (PIC) based protection system.
