| 摘 要： | 如果解决不好离网型风力发电机的大风限速保护问题,就会大大地降低其可靠性和安全性.文章从风轮与发电机的匹配人手,一改传统离网型风力发电机最佳功率匹配运行为峰前匹配运行,使风力发电机在大风时保持较低的风能利用系数,具有大风时的限速保护作用.

| Abstract: | If the overspeed control for small wind turbines could not be solved well,it will greatly reduce the reliability and security of small wind turbines.Started from the matching of rotor and generator and according to the traditional design method,the wind turbines should work at the optimum matching of rotor and generator.But in this paper,the wind turbines will work at the upgrade area and will be protected in high winds,because the power coefficient is lower. |

| Keywords: | wind turbine generator blade design match of wind turbine and generator |
