摘　　要：基于某2 MW风力发电机组发电、待机、风轮锁定等不同状态,仿真模拟偏航角度偏差对机组载荷的影响,获得了极端载荷下的偏航偏差角。基于叶片气动性能曲线对偏航过程中机组载荷变化的趋势进行理论研究,确定了不同风速下偏航限值的参考值,与仿真分析相结合制定了风力机组的偏航保护策略,可有效降低机组的极限和疲劳载荷。Based on the power production,standby,rotor lock and other states of a 2 MW wind turbine,the influence of yaw error on turbine loads is simulated to obtain the yaw error Angles of ultimate load.Studying the trend of load variation during yawing theoretically by the blade aerodynamic performance curve to determine the setting reference of yaw limit values at different wind speed,and the yaw protection strategy of wind turbine is developed by combining with simulation analysis,which can effectively reduce the ultimate and fatigue loads of wind turbine.
