摘要:

选择合适的风电场暂态模型是进行风电并网动态和稳定仿真分析的基础。首先从风电场装机容量、风电场并网点位置、风电场类型和场内机组的排列方式4个方面分析了风电场暂态模型选取时需要考虑的影响因素。然后面向大系统仿真，提出了满足差异性评价指标要求的，风电场不同暂态模型的选取阈值计算方法。进而给出了风电场暂态模型选取的实用准则。最后采用某实际地区电网数据验证了所提方法的有效性。

Abstract:

An appropriate transient model of wind farm is demanded for researches about the impacts of large scale wind generation. Firstly, the influence factors which should be taken into consideration of the transient model selecting for wind farm are investigated in view of four aspects as follows, the installed capacity of wind farm, types of wind farm, the point of interconnection of wind farm and the arrangement of wind turbines. Secondly, the calculation method of threshold selection for different transient models of wind farms for system simulation which meets the requirement of the error evaluation index is proposed and a practical criteria for selecting the transient model of wind farm is presented. Finally, the effectiveness of the proposed method is verified based on an actual regional power grid.

Key words: wind farm transient model model selection system simulation error index
