内容記述
Deeper understanding of the characteristics of the drive-train dynamic load under natural wind field is important because the failure it causes to wind turbine components will leads to long down time and sometimes serious accidents. In this study, field measurements are carried out on the main shaft of an active-stall controlled wind turbine located at a site where the surrounding ground surface varies from land to sea, and the dynamic characteristics of the bending moment, thrust and torque are evaluated according to the ground surface condition. While little difference could be seen between land wind and sea wind in the mean value of rotor thrust and torque, the mean tilt bending moment showed less value for land wind in higher wind speed compared to sea wind. For shaft tilt bending moment and torque there is a qualitative trend of load fluctuation per 1/3 of the rotation, which may considered to be the effect of each blade passing the tower shadows.
