风力发电仿真系统中模拟风轮机的理论研究

研究了在风力发电仿真系统中考虑到风轮机输出特性的模拟风轮机的新方法。风轮机的转速变化不仅与风速有关,而且与发电机联接的负载情况有关,除了说明风速以及风轮机特性对转速有影响以外,还指出发电机转矩对转速有反馈影响,同时采用了仿真的方法证实了模拟风轮机的运行特性与实际风轮机运行特性的相似性。此外,模拟风轮机优先采用了最大功率点跟踪技术,并且通过实验验证了最大功率点跟踪技术的有效性。

Analysis of the simulated windmill wind power generation system

The new method of wind power generation simulator considering output characterisics of the windmill in simulation system was proposed in this paper.The rotational speed change of the windmill is related to not only wind velocity but also load condition connected with the generator.Therefore,this paper pointed out that wind velocity and characteristics of the windmill had influence on rotational speed,in addition,the torque of the generator also had feedback influence.This paper confirmed the similarity between operation characterics of the simulator and the actual windmill by simulation.Moreover,the tracking technology of maximum power point was put to use preferentially in this simulator equipment.And the effectiveness of this tracking technology was proved by experiment.
