鸟类与涡轮机碰撞风险的特定地点模型是评估风电项目环境影响的重要组成部分。然而，现有模型假设鸟类飞行路径与涡轮机方向平行或垂直，并且其他方向不会显着影响预测的碰撞概率。我们描述了一个数学模型，该模型估计穿过风力涡轮机的鸟与涡轮机组件之一之间发生碰撞的概率。我们的模型在参考“塔克模型”和带模型的基础上得到了显着改进，通过考虑鸟类接近的不同角度，而不是垂直或平行于涡轮转子平面。我们通过坠落猛禽迁徙数据的案例研究证明，飞行路径和涡轮机方向之间的接近角度对碰撞概率和由此产生的死亡率估计有显着影响。我们的结论是，在估计鸟类与涡轮机碰撞风险时应考虑接近角。
A site specific model of avian-turbine collision risk is an important component of assessing environmental impacts from wind power projects. Existing models assume, however, that avian flight paths are either parallel or perpendicular to the turbine orientation and that other orientations do not significantly affect the predicted collision probability. We describe a mathematical model which estimates the probability of a collision between a bird passing through a wind turbine and one of the turbine components. Our model improves significantly upon the reference “Tucker Model”, and Band model, by accounting for different angles of avian approach other than perpendicular or parallel to the turbine rotor plane. We demonstrate, using a case study of fall raptor migration data, that the angle of approach between the flight path and the turbine orientation has a significant effect on the collision probability and resulting mortality estimates. We conclude that the angle of approach should be considered when estimating avian-turbine collision risk.
