低落差小流量の河川水を活用したマイクロ水力発電システムの開発と性能評価

抄録

The objective of this study is to evaluate the power generation performance of the axial flow propeller turbine, and ascertained that effective as a micro-hydroelectric power propeller in conditions of low-drop (drop the number of 1-5m) and small flow (Flow rate 0.1 ㎥/s or less). Further, we propose a micro-hydropower generation systems that combines a water wheel, controller, and generator to contribute to the spread of energy's local production for local consumption. In this experiment environment, measured a maximum generation output of 145W using a hydropower generation systems that power generation cost of 800,000 yen/kW. We has future subject to further improve the power generation efficiency of this system improving shape of the propeller, guide vanes of the installation, and ensure the effective head, etc. because the axial flow propeller turbine efficiency was 60% as low.
