This model accounts for the uncertainty about the loads acting on the wind-turbine rotor blade by the unstable wind distribution. A 20-year design lifetime is considered.
该种模型考虑了由于风速的不稳定所带来的作用在风力机叶片上分布载荷的不确定因素，并假定风力机的设计寿命为20年。
These methods are compared, and the method based on blade element theory is selected in modeling of wind turbine rotor.
通过对这两种方法的比较，选用基于叶素理论的方法建立了风轮模型。
