Abstract
This paper discussed the results of field tests conducted using a wind turbine installed at a plant located in the Tokyo Bay area. Special emphasis will be given to the examination of wind speed and the properties of power output as well as the properties of wind turbulence in strong wind conditions. Additionally, we discussed the feasibility and challenges of using medium-sized wind turbines for stand-alone power generation at commercial ports and fishing ports, based on surveys conducted in coastal areas of Hokkaido along the Sea of Japan.
