摘　　要：对影响广西沿海钦州风电场场址区域热带气旋的频数分布、强度特征、影响分类以及湍流强度的变化特征和等级等进行分析。结果表明:65a间进入钦州风电场影响区域的热带气旋共有69个,平均每年1.06个,多集中出现在7~9月;进入影响区域时热带气旋的强度以热带低压的频数最多,其次为强热带风暴和热带风暴,没有超强台风出现;其中有78%的热带气旋为效益型,16%的热带气旋为防御型,6%的热带气旋为破坏型。当热带气旋中心经过风电场附近时,风向由北风转为南风,风速急剧减小,湍流强度出现突增现象;热带气旋影响期间风电场的湍流强度大于A级,建议风电场选择湍流强度为A级的风电机组。Based on the analysis on the frequency distribution, intensity characteristics, influence classification of the tropical cyclone and the characteristics and grades of turbulence intensity in wind farm of Qinzhou coastal region, the results showed that 69 tropical cyclones have entered the wind farm affected zone during the past 65 years, 1.06 per year and concentrated from July to September. The tropical depression was the most frequent, followed by strong tropical storm and tropical storm, no super typhoon. 78% of tropical cyclones entering the wind farm were benefit type, 16% were defensive type and 6% were destructive type. When the center of tropical cyclones passed wind farm, wind direction turned from north to south, the wind speed decreased rapidly and the turbulence intensity suddenly increased. The turbulence intensity of the wind farm was sronger than class A during tropical cyclone affecting period, so the wind turbine generator was recommended to select class A.
