摘要
在永磁式直驱风机应急偏航控制中,难以预测环境风力变化情况,导致控制超调量大,为此,提出了永磁式直驱风机应急偏航控制优化方法.建立偏航液压设备数学模型,分析蓄能器连续性方程和偏航电机线性化流量方程.预测永磁式直驱风机工作位置风况,获取风机叶片与风速矢量之间的控制角和偏航参数之间的耦合方程,制定耦合矢量,实现永磁式直驱风机应急偏航控制优化.研究结果表明,在不同湍流强度、风向、风速工况下,设计方法的功率优化率能够达到 10%以上,其优化率高达 19.03%,验证了方法有效性.
Abstract
In the emergency yaw control of permanent magnet direct drive fans,it is difficult to predict changes in environmental wind force,resulting in a large overshoot.Therefore,an optimization method for emergency yaw control of permanent magnet direct drive fans is proposed.Establish a mathematical model for yaw hydraulic equipment,analyze the continuity equation of the accumulator and the linearized flow equation of the yaw motor.Predict the wind conditions at the working position of the permanent magnet direct drive fan,obtain the coupling equation between the control angle and yaw parameters between the fan blades and the wind speed vector,formulate the coupling vector,and achieve emergency yaw control optimization of the permanent magnet direct drive fan.The research results indicate that under different turbulence intensities,wind directions,and wind speeds,the power optimization rate of the design method can reach over 10%,with an optimization rate of up to 19.03%,verifying the effectiveness of the method.
