【摘要】：本文立足地区电网实际,深度挖掘配电生产管理系统、电网调度自动化系统、用户用电信息采集系统等电网大数据;利用信息技术,采用CIM模型,构建配网拓扑结构,建立配电规划模型,实现配电网现状的自动诊断分析,分析电网存在的供电半径过长、线径过细、联络不合理等问题,形成以线路为单元、变电站及配变为节点的数据分析库、规划问题库和项目储备库三大基础库;将电网大数据与GIS系统相融合,构建“大数据电力地图”,展示局部电网设备的薄弱环节,为配网规划提供直接依据;建立了一套从规划、储备、设计、评审和评估的全流程闭环的配网规划工作平台。论文从配网拓扑结构的构建、问题的自动诊断分析、与地理信息的结合、规划模型的建立、负荷预测模型的建立、规划算法的优化等几方面进行了有益的探索,体现了以公司战略、规划原则、问题为指导的规划工作思路,实现了电力大数据的智能化配网规划。
[Abstract]:Based on the reality of regional power grid, this paper deeply excavates the distribution production management system, power dispatching automation system, user information collection system and other power grid big data; Using information technology, CIM model is used to construct distribution network topology and distribution planning model, to realize automatic diagnosis and analysis of the current distribution network, and to analyze the problems existing in the power grid, such as too long power supply radius, too thin wire diameter, unreasonable connection, and so on. The data analysis database, the planning problem base and the project reserve database, which take the line as the unit, the substation and the substation as the node, are formed. The integration of power grid big data and GIS system, the construction of big data power map, showing the weakness of local power network equipment, to provide a direct basis for the distribution network planning; A closed loop distribution network planning platform based on planning, storage, design, review and evaluation is established. In this paper, the construction of distribution network topology, the automatic diagnosis and analysis of problems, the combination of geographic information, the establishment of planning model, the establishment of load forecasting model, the optimization of planning algorithm and so on, are discussed. It embodies the planning idea guided by the company strategy, planning principle and problems, and realizes the intelligent distribution network planning of power big data.
