International Journal of Multidisciplinary Research and Growth Evaluation www.allmultidisciplinaryjournal.com 18 | P a g e Design of a mini hydro-electric power plant AO Adetunmbi 1*, OI Dare-Adeniran 2 1-2 Department of Electrical/Electronic Engineering, Federal Polytechnic, Ile-Oluji, Ondo State, Nigeria * Corresponding Author: AO Adetunmbi Article Info ISSN (online): 2582-7138 Volume: 05 Issue: 01 January-February 2024 Received: 14-10-2023 Accepted: 16-11-2023 Page No: 18-21 Abstract The core concept of hydropower centers on capturing the energy produced as water moves from a higher elevation to a lower one. Conclusion The research conducted on the mini hydro-electric power plant, utilizing cost-effective and environmentally friendly water, classifies the hydro turbine as an environmentally friendly source of renewable energy.

1-800-346-9140 • www.attra.ncat.org A project of the National Center for Appropriate Technology By Leif Kindberg NCAT Energy Specialist Published February 2011 © NCAT IP383 Contents Micro-Hydro Power: A Beginners Guide to Design and Installation Introduction ......................1 Determining the Hydro Potential of Your Site .........................2 Environmental Impact .................................9 Regulatory Issues ..........11 Equipment ...................... Micro-hydro systems generally consist of the following components: • A trash rack, weir, and forebay to pre-vent debris from entering the pipeline and turbine • A pipeline (also called a penstock) to pipe water to the turbine • A powerhouse that contains the turbine and electronics • A water turbine that converts the kinetic energy of the fl owing water into mechanical energy that can be used directly or to drive a generator or other piece of equipment—this is the main component of a micro-hydro system • A tailrace to release the water back into the source it came from • Transmission lines to deliver electrical power where it is needed Th is publication is intended to include as much information as necessary to get you started in the process and to assist you generally at each step along the way of a micro-hydro project.

Induction motor and gearbox used as alternator Gearbox In-line coupling Turbine runner Figure 41 Direct coupled turbine and geared motor used as an alternator (Source: Practical Action) 10.6 Turbine rotor mounted on generator shaft Some of the important points to this system are: • The turbine and generator speed match • There has to be clearance between turbine and generator to avoid water splash interference • The bearings should be able to tolerate the side load of the turbine • Alternatively, a geared motor unit may be used as an alternator 57 | Micro Hydropower System Design Guidelines Worked Example 20 An alternator rated at 50kW output, 1500 rpm and 70% efficiency is to be driven by a turbine running at 450rpm.
