Enhancing energy efficiency in industrial pump units: the role of asynchronous motors with frequency converters

Abstract

This research investigates the enhancement of energy efficiency in industrial water supply systems through the implementation of asynchronous motors equipped with frequency converters. With the global increase in energy demand and the critical need for energy-saving solutions, this study focuses on optimizing the performance of centrifugal pumps, which are integral to water management in industrial settings. Utilizing a Variable Frequency Drive (VFD) system, the study demonstrates significant energy savings by controlling motor speed and reducing power consumption. The methodology involves a comprehensive simulation using the Simulink package to model the VFD's impact on pump performance. Key findings indicate that VFDs not only decrease energy usage but also provide precise control over motor speed and torque, thereby enhancing system stability and reducing mechanical wear. These results suggest that adopting VFD technology can lead to substantial cost savings and operational efficiency in industrial water systems. The practical implications of this research are vast, offering a pathway for industries to achieve sustainability and improved energy management. Conclusively, the study underscores the importance of integrating advanced control systems to optimize the energy efficiency and reliability of industrial water supply operations.
