# Optimizing Hydropower Plant Design. ## Uploaded by. AI-enhanced title and description. This document summarizes a computer program called HYDRA that calculates the optimal design parameters of hydropower plants. HYDRA uses an evolutionary algorithm called Genetic Algorithm to find the global optimal design by maximizing net profit from power sales. The model is tested on a theoretical example where the optimal solution can be found through conventional methods. When applied to an actual hydropower project, HYDRA's solution produced the same power plant size but with different waterway designs, improving overall economics and showing the importance of global optimization. ## Share this document. ## Footer menu. ## Support. ## Legal. ## Social. ## Get our free apps.

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.

continued on next page THE HYDROLOGIC CYCLE Solar Energy Water Vapor Ocean Evaporation Runoff Condensation and Precipitation Hydrostatic Head Sea Level Unit I Source of Hydropower UNIT GOAL To show the relationship between the solar powered water cycle and its effect on recharging of the watershed for hydropower. Most new hydro-electric development was focused on huge “mega-projects.” The majority of these power plants involved large dams which flooded vast areas of land to provide water storage and therefore a constant supply of electricity. HYDROELECTRIC POWER PLANTS Hydroelectric power plants capture the energy released by water falling through a vertical distance and transform this energy into useful electricity. In general, falling water is channeled through a turbine Hydroelectric Power 68 © 2000 PPL Corp. HYDROPOWER which converts the water’s energy into mechanical power. A large volume of water must pass through a low head hydro plant’s turbines in order to produce a useful amount of power. Hydropower: Using the energy of moving water to do work.
