This paper reports the considering of the behavier and power performance for the Straight Wing Vertical Axis Wind Turbine (SW-VAWT). Features of SW-VAWT are non-directivity and low noise. Therefore, SW-VAWT is suitable for an urban site because wind characteristics in an urban site are generally the low wind speed and the extreme change of the wind direction. Then, we carried out the simulation of the behavior for this turbine in the urban wind condition, and this simulation was based on the turbine motion equation which depended on the relation of the inertia, load, and initial mechanical loss. From this work, we clarified that the most important element of efficient driving of this turbine in the urban site was the decrease of the initial mechanical loss.
