摘要
本文在对风力机运行特性进行分析的基础上,建立了风力机的简易数学模型,在风速变化时,实时调节发电机的转速和转矩,使之运行在最佳叶尖速比上,以捕获最大风能。借鉴矢量控制思想,采用基于定子磁链定向的控制方法,给出了最大风能追踪控制系统框图,仿真结果验证了该系统最大风能追踪控制的准确性和有效性。
Based on the analysis of the operating characteristics of wind turbine, a simple mathematical model of wind turbine is established. When the wind speed changes, the generator speed and torque are regulated in realtime, so that it can run in optimal tip speed ratio and capture maximum wind power. In light of vector control theory, the maximum wind energy tracking control diagram based on stator flux oriented control is provided. Simulation results show that the control system of maximum power tracking is accurate and effective.
