基于电力大数据的输电线路防灾减灾分析系统设计——以贵州电网为例

A Disaster Prevention and Reduction Analysis System in Transmission Line Based on Power Big Data——A Case Study on Guizhou Power Grid

结合目前贵州电网输电线路防灾减灾工作的实际需求及电力企业海量大数据现状,提出了一种基于GIS的输电线路防灾减灾分析预警系统,以贵州电网常见的山火、覆冰和地质灾害为研究对象,以Arc GIS平台和Oracle 11g为载体,通过对气象数据、监测数据、运维数据等大数据集成分析,设计基于数据存储层、数据交换层、数据服务层、分析应用层和综合展示层的总体架构,形成具有山火、覆冰和地质灾害预警的灾害预防和提前防护功能的决策支持系统,通过实际运行可知,系统为贵州电网线路防灾减灾工作提供了有力的支撑。

Combined with the actual demand of disaster prevention and reduction in transmission line and large data status of power enterprises,we propose a disaster prevention and reduction analysis system based on GIS of Guizhou power grid. Taking Guizhou power grid common fires,icing and geological disasters as the research object,using Arc GIS and Oracle 11 g platform,We design the overall framework of the disaster prevention and reduction system of data storage layer,data exchange layer,data service layer,application layer and the presentation layer analysis. Through the integration of meteorological data,monitoring data,operation data,formed with the disaster prevention and advance the protection function of the decision system,it provides a strong support for the work of disaster prevention and reduction of Guizhou power grid.
