摘要 对风力机、传动链和发电机的数学模型进行了简化处理,得到了系统运动方程,结合风力机的转矩特性,提出了一种新的分段控制策略。这种方法不需要检测风速和功率信号,只根据叶轮转速来控制发电机的电磁转矩,便可实现风力机的最佳叶尖速比运行,从而最大限度地捕获风能。Matlab/Simulink仿真结果验证了算法的稳定性和有效性。 The system kinematical equation was derived from the simplified mathematical model of wind turbine, drive train and generator. A novel grading control strategy was proposed based on the torque characteristics of wind turbine. The new controller regulates generator＇s electromagnetic torque without wind speed or electrical power measurement. In the new control scheme, wind turbine can operate at optimal tip-speed ratio and capture maximum wind power. Matlab/Simulink simulation results show the stability and effectiveness of the presented control algorithms.
