Abstract— Micro-hydropower developments are the best option for power generation in isolated location. This type of activities can be introduced on little streams, waterways, and channels with practically no conspicuous impact on climate. The main issues in micro hydro projects are the significant expense of turbine, for which Pump as Turbine (PAT) are goal of this paper is to develop the best determination efficiency point for PAT arrangement by two different methods and used to compare the data what we obtained. Since no model have been created which might be used to ascertain the change issues for PAT, so in these paper centers around the exploration that has been done in this field? The point of this paper are to extant the preliminary arrangement and examination of PAT. The analysis results demonstrate the way to the centrifugal pump can work in turbine modes with no adjustment on mechanical parts with the most elevated effectiveness of 65.04%; in any case, at off-plan activity, the proficiency diminishes altogether because of unparalleled flow speed using wall edges’ inner region of a pump. Since the pump makers typically don't give datasheet showing the pumps attributes and performance while working as turbines, issue emerges as to comprehend how the pumps acts in the turbine mode. To determine the issue researchers have created dissimilar numerical models to track down the pumps as turbine mode and there useful qualities. In that paper, the best efficiency point (BEP) of pumps work as turbine (PAT) turbine are numerically resolve.
