摘要
风电机组风轮惯量持续增大,导致最-优发电阶段叶尖速比跟随能力变差的趋势明显。为解决此问题,通过最优转矩控制的结构调整,开发了具有惯性补偿功能的快速跟踪最优转矩控制算法;并根据风频谱图中含能的变化规律,进一步实现了舍弃高频波动的改进快速跟踪最优转矩控制策略;实现了大惯量机组叶尖速比快速跟踪的同时,输出功率波动不增加的控制效果。通过传递函数特性分析证明,系统的中频风速段响应能力及高频风速的抗波动性都有显著提升。仿真统计表明,新系统能提升最优发电风速段1.6%的发电量。
The inertia of wind turbine rotor continues to increase,leading to an obvious trend that the following ability of tip speed ratio becomes worse in the optimal generation stage.To solve this problem,a fast tracking optimal torque control algorithm with inertia compensation function is developed by adjusting the structure of the optimal torque control.According to the change rule of energy content in the wind spectrum diagram,the improved fast tracking optimal torque control strategy is further realized,which discards high-frequency fluctuations.The control effect of fast tracking of blade tip speed ratio of large inertia unit without increasing output power fluctuation is realized.Through the analysis of the transfer function characteristics,it is proved that the response capability of the system in the middle frequency wind speed band and the anti fluctuation of the high frequency wind speed have been significantly improved.The simulation statistics show that the new system can increase the generation capacity of the optimal generation wind speed range by 1.6%.
