    摘 要:不平衡載荷對輪轂、軸承、主軸、機艙偏航軸承、塔架等機械部件造成相當大的疲勞載荷。為降低機組關(guān)鍵部件的相關(guān)載荷,設(shè)計了一種獨自變槳控制算法,將機艙的旋轉(zhuǎn)坐標系每個葉片平面外的彎矩經(jīng)反向變換得出固定坐標系對應的機艙的風輪平面俯仰力矩和偏航力矩,采用PID控制減小相關(guān)載荷。通過PID控制實現(xiàn)變槳系統(tǒng)的動作,從而降低風輪平面受到的不平衡載荷,同時降低了風力發(fā)電風電機組疲勞載荷。
    關(guān)鍵詞:獨自變槳控制;風輪平面載荷不平衡;疲勞載荷;風輪平面俯仰力矩;風輪平面偏航力矩

    Abstract: Unbalanced loads cause considerable fatigue loads on mechanical components such as wheels, bearings, main shafts, nacelle yaw bearings, and towers.In order to reduce the relative load of the key components of the unit, an independent pitch control algorithm is devised. The bending moment outside the plane of each blade in the rotating coordinate system of the nacelle is inversely transformed to obtain the pitching moment and yaw moment of the wind turbine plane of the nacelle corresponding to the fixed coordinate system, and PID control is used to reduce the related load. The action of the pitch system is realized through PID control, thereby reducing the unbalanced load on the plane of the wind wheel, and at the same time reducing the fatigue load of the wind turbine.
    Key words: independent pitch control; unbalanced wind wheel plane load; fatigue load; wind wheel plane pitch moment; wind wheel plane yaw moment
