Energy Conservation of Three-Phase Induction Motors Through IoT-Enabled Intelligent Operation Management System

In this paper, we worked on the development of an IoT-based, low-cost industrial solution for the Automatic operation of 10 (Three-Phase Induction) motors installed at the disposal station. Manual operation of a large number of motors at the disposal station is a rigorous process that involves constant monitoring of wastewater levels in the wells and operating motors accordingly. The chance of human error in this situation is high which also involves risk to the expensive machinery. The proposed solution provides contactless operation of motors hence keeping the wastewater in wells to their minimum level while reducing the load in sanitation lines. The system is also capable of Auto/Manual mode selection, monitoring the level of water in wells through ultrasonic sensors, avoiding dry runs by operating the motors at an optimum level, and monitoring the running status of motors. Moreover, all this data can be visualized graphically on the web server for the required date and time. The comparison of results before and after the installation of this system shows significant energy conservation results which make this system feasible to install at large facilities.
