Abstract
The project focuses on the application of variable frequency drives for storm water pump stations. Multiple pumps are activated according to the water level in the storage box. The multiple starts of the regular starter based pumps at full speed cause the pumps to consume high inrush current. This problem can be solved by using variable frequency drives. Simulink is used in this project to show that the variable frequency drive based storm water pump stations consume less electrical energy and thus improve pump efficiently as compared to the constant speed pump stations.
