风电场尾流偏转控制效果受风况波动的影响显著。以我国北方某海上风电场为例
分析了在不同风况波动场景下
考虑风况均值与风况波动2种尾流偏转控制方法的效果。结果表明:风向波动对尾流控制的影响高于风速波动;对于考虑风况均值的尾流偏转控制方法
只有当风向标准差小于4°时才能有效提升全场发电量
而当风向标准差大于6°时
发电量降低;考虑风况波动的控制方法能够有效适应风向波动的影响
在所有风况波动条件下均能实现功率提升
证明了在尾流偏转控制中考虑风况波动的必要性。
The effectiveness of wake steering control in wind farms is highly sensitive to fluctuations in wind conditions. Taking a certain offshore wind farm in northern China as an example
the effectiveness of two wake steering control methods considering average wind condition and wind condition fluctuations under different wind condition fluctuation scenarios was analyzed. Results show that wind direction variability has a greater impact on wake control effectiveness than wind speed variations. The control strategy based solely on average wind conditions improves total farm power output only when the wind direction standard deviation is less than 4°
while when the wind direction standard deviation is greater than 6°
the power generation decreases. In comparison
the strategy that accounts for wind condition fluctuations maintains effective wake steering under all variability scenarios and consistently increases power output
demonstrating the critical need to include wind variability in wake control designs.
