摘　　要：随着风电产业的不断发展和并网总装机容量的不断增大,风电并网对电网的电能质量、电压和频率的稳定产生的影响越来越突出。文章首先推导出笼型异步风力发电机的特性方程,再针对该类型风机接入微电网进行理论分析,最后根据某海岛的大量运行数据分别对风机并入微电网的动态及稳态特性进行分析,证实了离网型微电网中风机运行稳定性。With continuous development of wind power industry and a total installed capacity increas- ing, the influence of wind power connected to the grid on power quality, voltage stability and frequency stability of power system is growing. First, a characteristic equation of cage asynchronous generator of wind turbine is derived in this paper. Then the influence of this kind of wind turbine integrated into mi- cro grid is theoretically analyzed. Finally, the dynamic and steady-state characteristics of connecting to the grid are analyzed respectively according to a large number of operating data of a certain micro grid in an island. The results confirm the running stability of wind turbine connected to a micro grid in offgrid mode.
