Influence of Installation Deviation of Thrust Bearing on Oil Film Flow of 1000 MW Hydraulic Turbine Unit. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. One of the main barriers is the lack of suitable methodology and software able to create a clear view of the SHP potential in the given territory, as well as a complete techno-economic analysis for certain locations. For example, one software is not able to take into account all the specifics of watercourses and plants; another does not have the option of selecting all types of turbines; in others, the calculation models are based on a limited number of equations that do not describe all possible cases; in some, economic analysis is oversimplified, etc.

To build a micro-hydropower system, you need access to flowing water on your property. Other considerations for a potential micro-hydropower site include its power output, economics, permits, and water rights. To see if a micro-hydropower system would work for you, you will want to determine the amount of power that you can obtain from the flowing water on your site. Once you've determined the head and flow, then you can use a simple equation to estimate the power output for a system with 50% to 70% efficiency or more, which is representative of most micro-hydropower systems. ### Determining the “Head” at Your Potential Microhydropower Site. In a potential microhydropower site, head is the vertical distance that water falls. The hose-tube method for determining head involves taking stream-depth measurements across the width of the stream you intend to use for your system -- from the point at which you want to place the penstock to the point at which you want to place the turbine.

> **NOTICE: Many people ask if it is feasible to generate electricity with one of these hydroelectric turbines by installing it in a water system powered by an electric motor-driven pump. They charge batteries 24 hours a day and the power can be drawn from the battery as needed, As little as 100 gallons per minute (GPM) falling 10 feet through a pipe, or 5 gallons per minute falling 200 feet through a pipe, can supply enough power to operate lighting and small appliances a small cabin or household. > By contrast, larger typical AC power hydroelectric systems, designed to deliver ready-to-use 120/240 VAC power, are not practical for most people because they need a constant water supply large enough to supply the peak power output that will be required, usually a minimum of several thousand watts, requiring hundreds or even thousands of gallons per minute, depending upon the pressure available. If you believe you have a site suitable for a larger AC hydroelectric system like this, use the output calculator immediately below and then go to our Large Hydroelectric Generator page.

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.
