| 摘要: |
| 从当前风力发电系统中使用恒速恒频存在的问题出发，提出了把双馈型变速恒频发电机应用于风力发电中，并且使用定子磁场定向的矢量控制方法研究双馈型风力发电机，建立了变速恒频风力发电系统的矢量控制数学模型，分析了风力发电机运行时的动态性能。结果表明风力发电机系统实行矢量控制后，发电机和原动机之间可以完全解耦，发电机定子电压的频率、相位与风速的大小无关，从而减少了对电网的冲击。 |

| Abstract: |
| To avoid the defects of constant-speed constant-frequency generator,the variable-speed constant-frequency double-fed generator is applied to wind power system.The stator-field-oriented vec-tor control is used in its study and the control model.The dynamic performance is discussed.It is shown that a full decoupling between the mechanical side and electrical side is possible and the frequency and phase of stator voltage are independent of the wind speed,which reduces the impact on power network. |
