| 摘 要： | 为解决风力发电机组所受工况瞬态多变且工作环境恶劣影响,建模分析了复杂、多变量、非线性的不确定系统.用叶素动量理论进行编程并集成到MATLAB/SIMULINK中,进行风力发电机组的气动性能计算,电机部分也在MATLAB/SIMULINK中建模,从而提出了一种基于MATLAB的失速型风力发电机组的动态仿真模型,模型中考虑了风力发电机组各部件之间的耦合作用关系及电机对风轮转速的耦合影响.利用提出的MATLAB仿真模型,对某失速控制型600 kW风力发电机组进行了仿真计算,试验结果验证了该模型的正确性.该仿真模型可以用于对风力发电机组的进一步优化设计、优化控制.

| Abstract: | Wind turbines operate in harsh environment with transient and variable working conditions.As a result,wind turbines are complicated,nonlinear,uncertain systems.Modeling and analysis of these systems are crucial to their design.Based on MATLAB,a new dynamic simulation model of a stalled wind turbine was presented.The blade element momentum theory and the state-space method were programmed into MATLAB/SIMULINK to calculate wind turbine aerodynamic performance.The generator was also modeled in MATLAB/SIMULINK,... |
