大规模风电场发电机组的等值简化对风电场的研究具有重要意义。提出一种风电场动态等值方法，该方法以滑差变化曲线作为反应风电机组运行点的分群原则，通过提取能够反映风力发电机组滑差动态响应情况的指标，进行风电场机组的动态分群；对滑差同调的机组参数加权平均，得到同调机群的等值模型，进而将风电场等效为几台等值机模型；最后，利用 Matlab/Simulink 仿真平台搭建风电场的详细模型和等值模型，并进行仿真分析，分别验证分群指标的有效性和风电场等值模型的准确性。

The equivalent simplification of wind turbines in the large scale wind farm has crucial in-fluence on wind farm studies.This paper proposed a dynamic equivalent method of wind farm.In this method,the slip coherency was used as the clustering rule which reflected the operating point of wind turbines.By extracting the clustering index reflected the slip dynamic response,the wind turbines were dynamically clustered.Then,by taking a weighted average,the same cluster wind turbines were aggregated and the equivalent model of coherent turbines wad gained.And the wind farm was equivalent to several equivalent turbines.Finally,the detailed model and equivalent model of wind farm was built in Matlab/Simulink environment.The simulation results verified the effec-tiveness of clustering index and the accuracy of wind farm equivalent model separately.
