Variable Frequency Drive Based Speed Control Of Three Phase Induction Motor In Sugar Mill Using Plc & Scada

The Variable Frequency Drive(VFD) based speed control of three phase induction motor using PLC(Programmable Logic Controller) and SCADA(Supervisory Control and Data Acquisation system) involves a sugar plant. The sugar plant contains various stages involved in the production of sugar starting from the inflow of sugarcane into the crushing machine. The speed of the sugarcane crushing machine depends on the amount of sugarcane flowing into the machine. When the conveyor which supplies the sugarcane increases its speed then the load on the machine increases automatically. Now-a-days in sugar plant, if heavy load enters into the crushing machine it cannot crush properly. So the wastage is increased and production rate will be reduced. To overcome this problem, we are going to implement the VFD based speed control of 3 phase induction motor. The whole unit is controlled by PLC and monitored by SCADA.
