摘　　要：大规模风电并网背景下,需要研究风电场功率输出特性。在风电场功率建模中引入了尾流模型,分别考虑了地形、风速风向以及风电机组布置等因素对风电场区域内风速分布的影响,定义了风电场功率影响因子,定量分析了尾流效应对风电场功率输出的影响情况。典型风电场下的仿真分析可为风电场建设选址以及区域风能评估提供参考。With large-scale wind power integrated into power system,it is significant to study the characteristics of wind farm output. This paper introduces the wake model into the wind farm modelling. Wind speed distribution in the wind farm is studied with consideration of terrain,wind speed,wind direction and layouts of wind turbines. The power factor is defined to analyze the impacts of wake effect on wind farm output. Simulations results can be helpful for the construction of wind farm and wind resource assessment.
