风电机组的制造成本和使用寿命取决于运行中的疲劳载荷、极端载荷和设计所依据的标准。目前，设计风电机组依据的大都是以欧洲环境特征为背景的标准，不加考虑地在台风地区使用会增加风险或制造成本。只有充分认识台风的气候特征和对风电机组的破坏机理，综合考虑，才能设计制造既能抗台风又能确保项目经济可行的风电设备。

Manufacture cost and service life of WTGS (wind turbine generator system)are dependent on fatigue load during operation,extreme load and designing standard. Nowadays, most designing standard adopted in China is made on the basis of external condition similar to Europe. When those standards are used for designing WTGS in typhoon area without consideration, project risk or manufacturing cost will rise. Typhoon-resistant WTGS with reasonable cost could not be designed and produced unless understanding meteorological characters of typhoon and its destroying mechanism.
