Wind power generation has recently become widespread in Japan. Straight Wing Vertical Axis Wind Turbines (hereafter SWVAWT) has some advantages for the wind power generation systems. For example, SWVAWT does not depend on wind direction. In addition, it is easy to make blades because the blade configuration of SWVAWT is more simple than that of propeller type wind turbine. In a wind tunnel test, we need a large scale wind tunnel which can duplicate the real condition for the wind turbine's moving. We tried to evaluate the performance of the SWVAWT in the field examination system. First, w searched self-starting performance of the test model. When the wind velocity is 0.45 m/s, the test model started moving. In addition, we searched relation between the tip speed ratio and the power coefficient of the test model.
