摘　　要：随着大规模风电的并网,需要研究风电出力波动和系统调频速度的关系,探讨大规模风电并网对系统调频的冲击。通过对张家口地区单个和多个风电场的调度EMS数据进行统计分析,验证了风电出力变化率呈正态分布,随着所统计风电场容量的增加风电出力变化率降低的特性,并得到了风电场出力变化率的数值范围,结合甘肃电网的系统调频速度数据,对风电接入率、风电出力变化率和系统调频速度的关系进行定性计算分析,得出了系统调频速度并非限制风电大规模接入制约因素的结论。With the large scale wind farm interconnected to grid, variability of wind power output brings the impact on frequency regulation. The relationship between frequency regulation speed and variability of wind power output should be studied. Through the analysis of wind power output data in Zhangjiakou area, it verified that variability of wind power output is normally distributed, and decreased with the increasing of the capacity of wind farm. Combined with the frequency regulation speed data of Gansu Power Grid, the relationship of variability of wind power output, wind power penetration and frequency regulation speed were analyzed, which concluded that the regulation speed is not the limiting factor of the large scale wind farm interconnected to grid.
