摘要：随着风电技术的发展，风机疲劳损伤成为风电场运营中的重要问题。针对风机主轴和塔架疲劳损伤的实时计算，提出了一种幅度自适应实时雨流计数法，建立了基于能量守恒的主轴扭矩和塔架推力模型，以准确预测满负荷风机承受的应力，在两者基础上，结合 SoftMax 函数，构建出 Min-Max 优化模型，通过固定时隙优化有功功率，以最小化风机组总损耗，并采用交替优化功率和风速的方法降低测量噪声带来的偏差。仿真结果表明，该方法显著降低了风机的累积疲劳损伤，提高了风电场运行效率和控制平稳性。

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
