摘要:

提出了一种新型自稳速机构,以用于风力发电机的恒频输出。从运动学原理的角度对传统反馈调节稳速机构与新型自稳速机构进行了对比分析。利用Simulink建立了具有不同稳速机构的风电系统模型,以FAST仿真获得的风轮时变转速为模型输入,在相同输入条件下对两种稳速机构的输出转速进行了比较。仿真结果表明:新型自稳速机构的稳速效果优于传动反馈调节稳速机构。

Abstract:

A speed stabilizing mechanism was introduced for outputing constant frequency current of wind turbine. The traditional feedback adjusting speed stabilizing mechanism and the novel speed self-stabilizing mechanism were contrasted and analyzed from the angle of the kinematics principle. The Simulink models of wind power system with different speed stabilizing mechanisms were built. The time varing speed of wind rotor simulated by FAST software served as the inputs of the model. Two kinds of speed stabilizing mechanisms worked under the same input conditions. The simulation results show that the quality of steady speed from novel speed self-stabilizing mechanism is better than that from traditional feedback adjusting speed stabilizing mechanism.
