摘　　要：分布式风力发电系统的并网运行,改变了所接入配电网的负荷构成和特性.随着风电渗透率的逐渐增加,这种影响将日益明显.以数字仿真实验为基本手段,利用Matlab/Simpowersystem工具平台搭建IEEE-14节点配电网络,分析研究分布式风力发电的不同接入容量和并网位置对配电网综合负荷特性的影响,构建"特征差异度"评价指标以定量评估其影响程度.As the distributed wind power generation system parallel into the grid, the load structure characteristics of the distribution network would be changed. This kind of influence will be more obvious along with the permeability increases gradually. Based on the digital simulation experiment, this paper used the Matlab/Simpowersystem platform to build the IEEE-14 node distribution network, and then deep researched the influence of the distributed wind power system to the comprehensive load characteristics, when the wind turbine connected to the grid on different geographical location with different capacity. At last, the evaluation index of ＂characteristic difference degree＂ was proposed to quantitatively evaluate the influence degree.
