摘　　要：随着我国风电的快速发展,由于风速的波动性和不可预见性而引发问题也越来越严重,如短时间内风电功率波动过大、大规模风机脱网等。若电网中其他发电机组不能对此迅速做出响应时,则有可能造成系统频率偏差,严重时甚至威胁系统的频率稳定。对风速特性进行了分析,选取了两种典型风速扰动来模拟对系统频率的影响;并对风电大规模脱网对系统频率的冲击进行了仿真模拟,提出了降低频率波动的优化措施。As the rapid development of wind power, the problems of wind speed volatility and unpredictability have been more and more serious, such as fierce wind power fluctuation in short times, large-scale wind turbines off the grid and so on. When other generators of the grid cannot response to the change, there will be some system frequency deviation, and it may threaten the frequency stability. The wind speed was analyzed, two kinds of wind disturbance were chosen to simulate the influence on system frequency, and the impact of large-scale wind power off the grid on the system frequency was simulated. Some optimization measures were proposed.
