Design and optimization of one kind stream micro water power generation device

Abstract

The streams has a certain amount hydro energy, can be used to generate electricity as a kind of clean energy, the use of streams and water to generate electricity has both realistic economic significance and important ecological and environmental protection. The purpose of this paper is to design one kind generation device which can be used in the low water head and rapid stream flow, according to water head and flow condition, the form of the generator was preliminarily designed, in order to realize the optimization of plant design and development, Numerical results showed that 8 degrees angle of outlet channel performed less loss; The shape type optimization design is carried out for generator room support column. After optimization, the performance improved greatly, and the power output increased from 13.9kW to 14.7 kW, and the efficiency increased from 73.5% to 78.3%.
