摘要：隨著風電技術的發(fā)展，風機疲勞損傷成為風電場運營中的重要問題。針對風機主軸和塔架疲勞損傷的實時計算，提出了一種幅度自適應實時雨流計數(shù)法，建立了基于能量守恒的主軸扭矩和塔架推力模型，以準確預測滿負荷風機承受的應力，在兩者基礎上，結合 SoftMax 函數(shù)，構建出 Min-Max 優(yōu)化模型，通過固定時隙優(yōu)化有功功率，以最小化風機組總損耗，并采用交替優(yōu)化功率和風速的方法降低測量噪聲帶來的偏差。仿真結果表明，該方法顯著降低了風機的累積疲勞損傷，提高了風電場運行效率和控制平穩(wěn)性。

Abstract: With the development of wind turbine technology, the issue of fatigue damage in wind turbines has emerged as a critical concern in wind farm operational management. For real-time fatigue damage assessment of wind turbine main shafts and towers, an amplitude adaptive real-time rainflow counting method is proposed. An energy conservation-based model of main shaft torque and tower thrust was established to accurately predict the stress experienced by wind turbines under full load. Based on the two, combined with the SoftMax function, a Min-Max optimization model was constructed. The active power was optimized through a fixed time slot to minimize the total loss of the fan unit, and the deviation caused by measurement noise was reduced by alternately optimizing the power and wind speed. Simulation results show that this method significantly reduces cumulative fatigue damage to wind turbines, improving the operational efficiency and smooth control of wind farms.

Key words: wind farm; communication delay; measurement noise; real-time rainflow counting method; Min-Max optimization model;fatigue damage
