J0530301 ビル風利用風力発電モデルの発電特性と実装可能性評価

Abstract

The aim of this study is to design and propose the size and layout of buildings which provide the better wind speed distribution for the higher power generation of wind turbine. A building model whose layout is like nozzle is proposed to obtain the acceleration of wind blowing through buildings due to contracted flow between buildings. In addition, the effect of the angle between two buildings on the power generation performance of the proposed building model is also investigated. For the feasibility check of installing the building model in some cities actually, the power energy output of wind turbine is investigated by considering the meteorological data such as wind speed and direction distribution for Fukushima city and Tsu city as an example. As a result, the proposed building models which have the angle between two buildings like nozzle of 90, 135 and 180 degree can provide the wind acceleration at the back of buildings for the wind blowing from the main wind direction and the angle of 135 degree is found to be the optimum building layout. In the case of installing the proposed building model in Fukushima city and Tsu city, the wind power energy output in winter is higher while that in summer is lower irrespective of the buildings angle. The interaction between the change in frequency distribution of wind speed direction through the year and the location of open tip of building model decides the power generation characteristics of the proposed building model.
