风电场建模是研究风电场接入电网运行和控制的基础。随着我国千万千瓦级风电场陆续投入电网运行，建立描述大型风电场的稳态和动态行为的数学模型是一个关键课题。对现有风电场建模研究成果从风速-功率关系模型、稳态潮流计算模型、动态模型和暂态模型四方面进行分析和总结；并针对近期出现的大型风电场连锁切机事故，提出了风电场连锁动态过程建模的概念和必要性。通过对现有风电场建模方法的综述，旨在指出目前大规模风电场建模存在的问题和需要进一步研究的方向。

The model of wind farm is the foundation of the grid operation and control with wind farm integration. Establishing mathematical models to describe the steady-state and dynamic behavior of large-scale wind farm is a critical issue with tens of millions kW wind power being injected into the grid one after the other. The research of wind farm modeling is analyzed and summarized from four aspects which are wind speed-output power characteristic model, power flow calculation model, dynamic model and transient model;the concept and the necessity of the cascading dynamic process of the wind farm are proposed aiming at the cascading trip-off of large-scale wind farm recently. The problems of large-scale wind farm modeling and further research are pointed out based on an overview of the existing approachs of wind farm modeling. <br> This work is supported by National Natural Science Foundation of China (No. 51190103 and No. 51177043).
