摘要
介绍了应用Matlab7.0对含风电的电网建模以及风速突然变化、系统电压突然下降和电网发生单相接地短路3种情况的仿真分析方法和机理。仿真结果表明,变速风力机驱动双馈式异步风力发电机组的变速平稳,机组效率高,对电网也可以起到一定的稳压和无功调解的作用。
In this paper the model of wind power system is built with Matlab7.0. At the same time the method and principle of simulation analysis in the wind power system is introduced in three aspects： a suddenly change of wind speed, a voltage sag on the system and the impact of a single phase-to-ground fault. The result show the Doubly-Fed Induction Generator （DFIG） with Variable-Speed Wind Turbine has high efficiency. The speed of the wind turbine is adjusted smoothly. The DFIG also can stabilize the voltage and regulate the reactive power of the power system to a certain extent.
