Increasing Water Pump Station Throughput by Introducing VFD-Based IE4 Class Synchronous Reluctance Motors with Improved Pump Control

摘要

/hr and servicing a head of 80m is studied, with the results following an energy efficiency upgrade being reported on. Energy efficiency is quantified by employing the International Performance Measurement and Verification Protocol (IPMVP) on the holistic system as opposed to the measurement of individual components as outlined in, amongst other standards for other components, the test methods for determining losses and efficiency of VSD-fed motors IEC 60034-2-3. The IPMVP protocol further provides the parameters for quantifying specific energy consumption improvement of a complete pump system. The pump system supplies water for public use in the northern region of South Africa. An overall energy saving of 36% for the complete pumping system is reported whilst maintaining unchanged water delivery; alternatively water pump station throughput can be increased by 58% without increasing energy consumption.
