شبیه سازی زمان واقعی سیستم پمپاژ موازی سرعت متغیر

Energy is the world’s fundamental requirement to perform any work. Presently, insufficiency in energy is the major challenge faced throughout the world. Among the total installed loads, pumping contributes, 30% of them. Thus considerable improvement in energy savings is possible by increasing the energy efficiency of the pumping system. Nowadays, the usage of variable frequency drives (VFDs) for pumping system is becoming inevitable due to their control over flow rate variation. This paper presents the performance of real time simulated variable speed multi pumping system. The variable speed pumps using affinity laws reduces power up to 80% when there is a reduction in speed of 50%. The efficiency of the pumping system is identified by incorporating the efficiency of both motor and the variable frequency drive (VFD).
