风力发电机组的台风适应性设计方法研究

摘要

Design load cases determines the external loads and operating environment of wind turbine. Due to existing design guidelines or standards don’t consider the impact of Tropi-cal Cyclones(referred to as TC)or Typhoon,when wind turbine operating in TC areas,the de-struction of the risk increases,manufacturing and maintenance costs increase. Using TC ob-served data,turbulence intensity,gust characteristics and wind direction characteristics were studied in TC landing process,a adaptive design method of wind turbine to typhoon conditions is suggested,including typhoon characteristics,typhoon design conditions,structural design, control strategy,operation and maintenance strategy. The typhoon design load is simulated based on the suggested method;The result shows that the suggested method of offshore wind turbine anti-typhoon design has a better economy and safety.%设计工况决定了风电机组的外部载荷和运行环境。由于目前的风电设计标准没有考虑台风环境的影响，运行于台风地区的风电机组遭到破坏的风险增大，制造和运营成本增加。利用观测到的热带气旋数据分析了台风过程中的湍流强度、阵风特性和风向变化特性，提出了包括台风特性、台风工况、结构失效分析设计、台风控制策略和运维策略的系统性的风电机组台风适应性设计方法。文章基于上述方法，计算分析了风电机组在不同工况条件下的载荷；结果表明，采用本文方法设计的风电机组，应用于台风多发地区，具有更好的经济性和安全性。
