在进行风电场布局优化时
如果目标函数仅考虑年发电量AEP
可能导致优化后风电场的部分风力机疲劳荷载增大
进而增加运维成本
因此优化得到的风电场布局可能不是最优解。针对上述问题
开展考虑风力机疲劳载荷限制的风电场布局优化研究。首先
通过输入每台风力机的有效风速和有效湍流强度至代理模型来预测等效疲劳载荷。然后
使用开源风电场优化平台TOPFARM对风电场进行布局优化
并在优化过程中增加对寿命周期等效疲劳载荷LDEL限制来降低风力机的疲劳载荷。最后
对Horns Rev 1典型风电场进行考虑疲劳限制的布局优化研究。结果表明:与不考虑疲劳限制相比
优化后的风电场会牺牲少量的AEP
但可换来LDEL较大程度的降低。
When optimizing the layout of a wind farm
typically only objective functions such as Annual Energy Production (AEP) are considered
easily causing increased fatigue damages for wind turbines and higher operation and maintenance costs for the wind farm
thus the final layout of wind farm might not be the optimal if the optimization codes don't consider the wind turbines fatigue loads constraint. On account of that
this study proposes practical measures to address this issue. Firstly
the damage equivalent loads are predicted by inputting load surrogates for the effective wind speed and effective turbulence intensity of each wind turbine. After that
the open-source wind farm optimization platform TOPFARM is utilized in this study to optimize the wind farm layout. Furthermore
the constraint is added to limit the Lifetime Damage-equivalent Fatigue Loads (LDEL) of the wind turbines during the optimization process. Finally
this study optimized the layout of Horns Rev 1 wind farm considering constraints on wind turbine fatigue loads
concluding that the optimized wind farm only sacrificed a small amount of AEP in exchange for a significant reduction in LDEL.
