Abstract: Different from European offshore wind farm, typhoon seriously restricts offshore wind development in China. Based on aerodynamic analysis of offshore wind turbine in typhoon condition, wind pressure on blade, tower and turbine winding are calculated. Anti-typhoon cost is analyzed with IEC 61400 and GB/T 31519—2015, GB/T 18451.1—2012 standard requirement. Then measures of offshore wind turbine are proposed to improve typhoon resistance. Those measures include strengthen offshore wind turbine blade material, lengthen of retractable blade positioning mechanical arm to fix blade, change central tower structure from bolt connection to subsided upper tower and improved anti-typhoon control strategy. All those measures can help to build cost effective and practical anti-typhoon offshore wind turbine.

Key words: offshore wind turbine, typhoon analyse, anti-typhoon measure
