1 INTERNATIONAL CONFERENCE ON SUSTAINABLE ENERGY TECHNOLOGIES-2017 Indigenous R&D of Micro Hydro Power Plants to Improve the Pace of Off-Grid Electrification Javed Ahmad Chattha Ghulam Ishaq Khan Institute of Engineering Sciences and Technology, Tel: Ext: 2203, 25/09/2017 1

2 Micro Hydro Power System Capacity: 100 kw or less Typically uses run of the river streams Main Components of MHPP Mechanical Turbine Electronic Load Controller (ELC) Electrical Generator Condition Monitoring System 25/09/2017 2

3 Why R&D and Testing is Required? Current Status of MHPP in KP: Installation of locally manufactured MHPPs Fail to grasp the full potential of the site conditions Mostly by non-engineering approach Stop/breakdown because of poor design Without periodic condition monitoring Engineering Approach Requirement Capture Engineering Design Modeling & Simulation Analysis Implementation Optimization Testing Manufacturing 25/09/2017 3

6 1) Pump as Turbine (PAT) at Mardan, KP Why PAT. Standard pump units, when operated in reverse are advantageous over turbines for micro-hydroelectric power generation. In pump; the flow of water acts against gravity whereas in case of turbine the flow of water acts along gravity. Pumps as mass-produced, are available for a wide range of heads and flows at considerably lower cost and with shorter delivery times than the equivalent turbines. Spare parts are easily available. Given the right conditions, PAT s can be used over the range normally covered by multi-jet Pelton turbines, cross flow turbines and small Francis turbines.
