| 摘 要： | 以Matlab/Simulink为工具,建立了双馈发电机组并网的仿真模型,并对负载发生变化、风速突变、电网电压跌落和电网发生故障几种情况进行了仿真和分析。仿真结果表明:双馈型风力发电机对于小的扰动,能够实现功率的稳定输出,同时对电网有一定的无功调节的作用。但在大的故障时,会引起风机的保护动作,使风机脱网,引起电网电压的波动,仿真为进一步分析故障提供了基础。

| Abstract: | In this paper,the simulating model of doubly-fed induction generator (DFIG) linked with power systems was built with Matlab/Simulink.Then,simulating and analyzing in the aspects of the change of load,change of wind speed,voltage sag and grid fault was made.The result of simulation expresses that DFIG is able to supply a stabilized active power output and will have an effect of stability on the reactive power to a certain extent when meeting small disturbances.However,great disturbances may cause the protection system of DFIG to cut off the DFIG from the grid,which will cause the voltage fluctuate.This simulation povides a base for the further fault analysis. |
