Pumps as turbines for low cost micro hydro power

Abstract

Small centrifugal pumps are suitable for use as hydraulic turbines and have the advantage of being mass produced in many countries throughout the world. When used with an integral induction motor, they can be installed as a combined turbine and generator unit. Recent research and development work carried out at Nottingham Trent University in collaboration with the Intermediate Technology Development Group has concentrated on two aspects that had previously held back the wider application of this technology. A standard design of Induction Generator Controller (IGC), enabling these units to be used for isolated micro hydro schemes, has been proven, and is now being manufactured in five countries world-wide. Progress has also been made on the application of performance prediction methods which facilitate the selection of a pump unit for particular site conditions.
