• In straight channel reaches an artificial bend, a groyne island or guide vanes may be designed to cause the required curvature of flow Use of artificial groyne (e.g. island) to induce desired curvature to flow at intakes Guide vanes layouts upstream of intake for sediment exclusion Hydropower Engineering Instructor: Mekete Dessie (PhD) Faculty of Civil & Water Resource Engineering Dam intakes • For valley dam plants, the intake structure is provided usually in the body of the dam; • The penstocks are embodied in the dam • The main features of such an intake are: a trash rack structure in front of the dam, a bell mouth inlet horizontal or inclined alignment, control gate installed either at or after the bell mouth, Cage-shaped intakes resting against the face of the dam and supported on slab cantilevered from the dam provide larger area of entry than the penstock intake area thus reducing entrance losses Hydropower Engineering Instructor: Mekete Dessie (PhD) Faculty of Civil & Water Resource Engineering Tekeze Dam intake structure Hydropower Engineering Instructor: Mekete Dessie (PhD) Faculty of Civil & Water Resource Engineering • The most common type of intake structure is the vertical structure, generally referred to as a free-standing intake tower.

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.

(a) Guide Specification CE-2203 states the following: In the evaluation of Transformer Auxiliary Power, the power required for motor-driven fans and oil-circulating pumps should be evaluated on the basis that each horsepower of motor rating in excess of the number of horsepower excluded from evalua-tion is equal in value to approximately 40 percent of the capitalized value of one kW of loss used in the transformer efficiency evaluation.
