Abstract
Three phase induction motors are widely used motor in sugar industry because of its simple maintenance. In recent years, Variable Frequency Drive is used to change the rotating direction and speed of three phase induction motor. The speed of three phase induction motor is controlled and monitored using Programmable Logic Controller and Supervisory Control and Data Acquisition system in a sugar plant through Variable Frequency Drive. The sugar plant contains various stages for the production of sugar starting from the inflow of sugarcane into the crushing machine. The induction motor is used to operate the crushing machine in the sugar plant. The speed of the crushing machine depends on the quantity of sugarcane flowing into the machine. The Variable Frequency Drive controls the speed of the crushing machine depending upon the load entering by increasing or decreasing the RPM of the crushing machine. This operation is controlled by the Programmable Logic Controller and monitored using Supervisory Control and Data Acquisition system. The sensors are present in the conveyor belt which acts as input for programmed logic controller which senses a sugarcane load on the belt and send the signals to the Programmable Logic Controller.
