面向配网台区的综合评价模型研究与可视化应用

摘要

With constant expansion of distribution network,mass heterogeneous data has shown an exponential growth.In order to improve the distribution network operation management and address problems in the distribution network planning and construction,this paper proposes that a comprehensive evaluation model distribution network platform should be built based on GIS,big data and visualization technology.The work starts with the minimum unit of the distribution network and k-mean cluster analysis,subjective and objective weight addition,neural network and other methods are used.The visualization technology can be used for a multidimensional stereoscopic display of the evaluation resuh,which enables the staff to quickly locate the problem and identify the fault substation area.The staff can thus be fully informed of the operation and maintenance status of distribution network lines,substations and the whole substa tion area,and analyze unusual actions more accurately.The fea sibility of the proposed model has been proved through practice.%随着配电网规模的不断扩大,海量异构数据呈指数级增长,为了提高配电网的运维管理水平,解决配网建设、规划中的诸多问题.文中提出基于大数据、GIS、可视化技术,从配网最小单元台区入手,利用Kmean聚类分析、主客观权重加成、神经网络等方法建立配网台区综合评价模型,并利用可视化技术对评价结合进行多维立体展示,让工作人员快速定位问题,找出问题台区;从而对配网线路、变电站及整个台区的运维状态充分把握,提升问题异动分析的精确度,通过实践所提内容切实可行,能够对台区状态进行立体展示,促进整体配网运维与规划.
