基于WebGIS的架空输电线路防灾减灾系统的研究及应用

Research on overhead transmission line disaster prevention andmitigation system based on WebGIS

架空输电线路防灾减灾是电网抵御外部灾害保证安全运行的重要保障,结合目前电网输电线路防灾减灾的实际需求,本文提出研究了一种基于WebGIS的架空输电线路防灾减灾系统。以覆冰、雷电、山火、鸟害等常见的灾害为研究对象,以Openlayers平台和Oracle数据库为载体,通过对气象数据、监测数据以及运维数据等多源数据集成分析,设计基于数据存储层、数据交换层、数据服务层、业务逻辑层、业务控制层和综合信息显示层的总体架构,形成具有输电线路可视化、灾害监测、灾害预警为一体的灾害预防和决策支持系统。通过实际运行情况证明了该系统为电网输电线路防灾减灾工作提供了强有力的支撑。

Overhead transmission line disaster prevention and mitigation is an important guarantee for the external power grid to resist disaster and ensure safe operation. Combined with the actual demand of transmission lines in Yunnan power grid disaster prevention and mitigation at present, we propose an overhead transmission line disaster prevention and mitigation system based on WebGIS. With ice, lightning, fire, bird and other common disasters as the research object, based on Openlayers platform and the Oracle database as the carrier, through the integrated analysis of multi-source data of meteorological data, monitoring data and operation data, the overall architecture is designed based on data storage layer, data exchange layer, data service layer, business logic layer, data interaction layer and comprehensive display layer. Then finally a disaster prevention and decision support system is formed with transmission line visualization, disaster monitoring and disaster warning. The actual operation shows that the system provides strong support for the disaster prevention and mitigation work of the transmission line in Yunnan power grid.
