英文要約Title: New Energy Technology Development/ New Energy Venture Business Technology Innovation Program (Wind Power Generation And Other Untapped Energies) Feasibility study on development of small vertical axis wind turbine that has safe and reliable self control mechanism against over speed rotation (FY2009-FY2010) Fy2009 Annual Report
Based on the new idea of safe and reliable self control mechanism against over speed rotation proposed by the University of Tokushima, the development of small vertical axis wind turbine was investigated. Following results were obtained. (1) For the decision of wind resistant design of a wind turbine installed in the rooftop of high rise buildings, aerodynamic forces acting in rotational wind turbine were measured in wind tunnel by using scale model and they were used for the wind resistant design of wind turbine and wings. (2) Lightening and lowering the cost of main body of wind turbine were studied and about 14% was lightened, however it is necessary to try with a further lightening and cost reducing. (3) For lightening and cost reduction of wing, about 14% was lightened. (4) To achieve the improvement and lowering the cost of installation and construction for wind turbine, an important element and the problem were able to be confirmed. (5) The power generation control algorithm was constructed by PWM control taking into account the best tip rotation speed ratio. (6) For business plan making, the hearing survey of demanded installation location and performance and price, etc. was investigated against the Tokushima prefecture. The answer that the installation of the wind turbine can be examined enough in the circumference green space and commercial land of the Tokushima airport constructing a new terminal was gotten. The installation results will be made in communal facilities in the Tokushima prefecture first. Next, it widens sales to private facilities (high-rise apartment and plant equipment). (7) In order to verification of power generation performance, the communication system between the measurement server of the examination site and the server of the university with the Internet line was constructed. The acquisition of power generation data began, and the power generation performance was verified. The rotational speed of the wind turbine increased in wind velocity of 4m/s or more. The pinwheel maintained the high rotation once as for the high rotation at the velocity of the wind of 2m/s or less. As a result, the cut-in wind velocity can almost achieve 2.5m/s that is the targeted value. The maximum power generation efficiency was about 25%, and it did not reach the target of 30%. In the future, it is necessary to examine the shape of wing and the cross section shape of the support structure and to decrease the polar moment of inertia of the main body of the wind turbine more.
