变桨距风力发电机特殊运行状态的仿真实验

Simulation Experiments for Variable Pitch Wind Turbines in Special Events

关注国内研究较少的风力发电机的特殊状态,基于FAST平台选择了特定的变桨距风力发电机模型,对于风力发电机的启动、关机和故障过程3大类中的7个特殊状态进行了仿真实验。将所得结果在MATLAB中绘图,得到了风力发电机风轮转速和发电机电磁功率在各个特殊状态下随时间变化的曲线,并对各个过程进行了简要的分析。

This article focused on the special events of wind turbines which had been seldom studied in China. Based on the FAST platform, and with selection of a certain type of variable pitch wind turbine, simulation experiments were conducted on 7 special events in the startup, shutdown, and fault of the wind turbine. The results were plotted in MATLAB, and the curves of the rotor speed and electrical power of the generator in each special event were therefore obtained with a brief analysis on the course of each event provided.
