大规模风电接入电网后，其运行对系统的小干扰稳定性将产生一定的影响，为研究风电在不同运行工况对系统动稳定性的影响。基于CEPRI9v6系统算例针对风电场的接入进行了小干挠稳定性仿真研究。深入分析了风电机组在典型阵风、渐变风、随机噪声风风速扰动情况下，恒速异步风力发电机组、变速恒频风力发电机组分别接入系统时对系统阻尼特性的影响，并且通过系统仿真算例，验证了分析结果，为大规模风电并网时风电机组选型以及系统稳定分析提供了建设性意见。

The small signal stability of power grid will be influenced as a result of large -scale wind farms integration into pow-er system.In order to study the impacts of wind power on dynamic stability of the system in different operating conditions , the small signal stability is simulated and researched based on a simple CEPRI 9v6 power system aiming at the integration of wind farms.The effects of grid integration of constant speed wind turbine generators and variable speed wind turbine generators on damping characteristics of power system under various wind speed disturbances such as the typical gust wind , ramp wind and noise wind for different wind turbine generators are analyzed respectively .The given analysis results are verified by simulation results of actual power system .The results provide the constructive suggestions for the selection of wind turbine generators dur -ing the integration of large -scale wind power system and the analysis of system stability .
