摘要
为了研究风力发电系统在不同风力条件下稳定运行的控制方法,该文首先建立了复杂风速、风力机和永磁同步发电机数学模型,为了实现快速稳定的风力发电系统控制,设计了基于滑模变结构的控制器,最后利用Matlab/Simulink搭建了综合风速模型以及永磁同步风力发电机系统仿真模型,验证了所设计系统的有效性.仿真实验结果表明,采用滑模变结构控制比传统PI控制的系统更加稳定,响应速度更快.
In order to study the stable operation control methods of wind power generation system under different wind conditions,the mathematical models of complex wind speed,wind turbine and permanent magnet synchronous generator are firstly established in this paper.Finally,Matlab/Simulink is used to build a comprehensive wind speed model and a permanent magnet synchronous wind generator system sim⁃ulation model,which has verified the effectiveness of the designed system.Simulation results show that the sliding mode variable structure control system is more stable and faster than the traditional PI control system.
