Design of a Micro-hydrokinetic Power Generation System Implement an Oscillating Hydrofoil in river Rui Han, Jessica Cherry, Robert Kallenberg Graduate Research Assistant International Arctic Research Center Dept. of Electrical & Computer Engineering University of Alaska Fairbanks
Project Definition • Survey of the micro-hydro technology and resources. • Design an oscillating hydro-foil energy conversion system for hydrokinetic electric power generation in river and tidal.
Background-Nation Wide • Climate change calls for renewable energy • In 2009, U.S. hydrokinetic Power ≤ 1MKW, hydropower > 77,000 MKW • As of 2009, the FERC issued 146 applications to study 9,000MKW • Prediction: Hydrokinetic Energy could provide 13,000 MKW to the U.S. by 2025 Quadrillion Btu EIA Annual Energy Outlook 2010
Background-State wide • Resources • Many big rivers • 90 % of U.S. tidal • 50% of U.S. wave • Energy Policy • SB 220: 18 million increase to 250 million. • HB 306: 50% renewable electricity by 2025. • Uneven Electricity Cost Across State • High energy cost for rural regions, most of which are near rivers
Technology • Turbine (Dominant) “EnCurrent” by New Eenrgy RivGen™ by ORPC SmarTurbine™ by FFP * Picture courtesy of the original company
Our Technology • Heave and pitch movement • Motion controlled by the trim tab. • Less hazardous to fish • Genetically prevented from debris attacks
Experiment • Prototype manufacture • Hydrofoil • Scotch Yoke • PMG Coupling • Verify the original idea • Oscillating? • Linear to Rotational? • Estimate the capacity
