A Review on Pump as Turbine for Micro Hydropower Plants

Abstract

Hydropower is the top most renewable energy source and micro hydropower plant is one of the best solutions for energy crisis in remote, rural and hilly areas. In micro hydropower plants cost is equally important criteria as the efficiency. We can use centrifugal pump as the hydraulic turbine as it has advantage of being mass production in many countries throughout the world and low cost. As centrifugal pump used as turbine has no flow control mechanism so the part load efficiency is poor. This paper reviews the different work carried out by different researchers in the field of Pump as Turbine.
