摘要

以Matlab/Simulink为仿真研究工具,实现了空气动力学子系统、机械传动链子系统,风能转换系统中电力电子变流及控制、风力发电机组并网的建模.采用模块化设计思想,实现了风能转换系统中各个子模块的建模仿真及系统集成仿真,通过应用实例说明该系统控制平台可灵活应用于风力发电系统的优化与控制,缩短控制系统的开发周期,为风力发电系统投入实际工程应用提供良好的技术支持.%By using Matlab/Simulink software as a simulation platform,a wind energy conversion system (WECS) was constructed. Moreover, the mathematical models of the aerodynamics subsystem, the drive train subsystem, the power electronics converter subsystem and wind power generation grid-connected subsystem were created. Furthermore, with the modularization design method, each subsystem can be simulated and integrated simulation can be realized. Actual application shows that this platfrom is feasibile,and can shorten the development circle of the control system, providing technical support for actual construction of wind power plant.
