Abstract

In order to propose an anti-typhoon design method suitable for China’s national conditions, this paper firstly introduces the basic characteristics of typhoon such as strong extreme wind speed, prominent non-stationary, quick change in wind direction and synchronization with huge waves. Then common failure modes of offshore wind turbines under typhoon are analyzed, including overall overturning, tower failure and blade damage. Based on this,the design concepts of anti-typhoon are explored, which suggested that the subversive failures should be prevented and the anti-typhoon design based on reliability should be adopted. Furthermore, some anti-typhoon measures are proposed, such as vibration control technology and concrete wind turbine tower, which provide references for the anti-typhoon design of offshore wind turbine in China.

Key words

offshore wind turbine / typhoon characteristic / failure mode / anti-typhoon design / anti-typhoon measure
