广东地区台风工况下的海上风资源参数特性分析研究

The Characteristic Research of Offshore Wind Resource Parameter in the Condition of Typhoon

近年来,广东、福建、海南地区海上风电发展迅速,然而在该海域范围内经常遭受超强台风破坏性袭击,对风电机组抗台风性能提出了更高的要求,因此有必要对台风工况下的风资源参数做详细研究。文章参考广东某地区海上测风塔资料,针对测风塔受台风影响区域,提取了观测时间段内的6次不同特性且较为完整的台风数据,分析了台风期间的风速风向、空气密度、湍流强度、阵风系数以及风速的垂直切变等参数随时间变化的特性,总结了在不同情况下台风过境对该地区风资源的影响及变化规律,为抗台风机组设计及控制提供了重要参考依据。

The offshore wind power of Guangdong,Fujian and Hainan is developing rapidly in recent years.Considering the severe influence of typhoon at that region,it is necessary to study the parameters of wind resource for the purpose of improving the wind-resisting of turbine.The paper is based on the data from offshore mast of Guangdong,there are eight different types of typhoon during the observation period.According to the analysis of wind resource parameters,for example,velocity,direction,air density,turbulence,gust factor,vertical shear and so on,the change rule of parameters with time is summarized when a typhoon has hit from coming to leaving.The conclusion can offer valuable references for anti-typhoon designing and controlling of Ming Yang Company.
