摘要：隨著風(fēng)電技術(shù)的發(fā)展，風(fēng)機(jī)疲勞損傷成為風(fēng)電場(chǎng)運(yùn)營(yíng)中的重要問(wèn)題。針對(duì)風(fēng)機(jī)主軸和塔架疲勞損傷的實(shí)時(shí)計(jì)算，提出了一種幅度自適應(yīng)實(shí)時(shí)雨流計(jì)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(zhǔn)確預(yù)測(cè)滿負(fù)荷風(fēng)機(jī)承受的應(yīng)力，在兩者基礎(chǔ)上，結(jié)合 SoftMax 函數(shù)，構(gòu)建出 Min-Max 優(yōu)化模型，通過(guò)固定時(shí)隙優(yōu)化有功功率，以最小化風(fēng)機(jī)組總損耗，并采用交替優(yōu)化功率和風(fēng)速的方法降低測(cè)量噪聲帶來(lái)的偏差。仿真結(jié)果表明，該方法顯著降低了風(fēng)機(jī)的累積疲勞損傷，提高了風(fēng)電場(chǎng)運(yùn)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
