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.
4 Guide on How to Develop a Small Hydropower Plant ESHA 2004 Figure 1-3 Low head scheme integrated in the dam 1.3.2 Schemes with the powerhouse at the base of a dam A small hydropower scheme cannot afford a large reservoir to operate the plant when it is most convenient, the cost of a relatively large dam and its hydraulic appurtenances would be too high to make it economically viable. 5 Guide on How to Develop a Small Hydropower Plant ESHA 2004 Figure 1-4 Low head scheme using an existing dam Provided the dam is not too high, a siphon intake can be installed.
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.
