大型风力发电场等值建模研究关键问题分析

Analysis of Key Problem on Large Scale Wind Farm Equivalenting Modeling

介绍大型风电场等值建模的主要特点和发展过程，并对动态等值模型和稳态等值模 型进行分析比较，同时对当今研究的关键问题进行简要分析。

For more than a decade, behavior of wind farm with respects to electric power system has been modeled. Up to the mid 90＇s, most investigations were related to voltage behavior. Consequently, the wind farm models developed were hardly suitable power system stability analysis. The objective of this paper is to briefly assess the state-of-the-art of wind farm equiv- alenting modeling and describes key aspects for specification and applications of wind farm equivalenting modeling.
