基于GIS技术的电网综合信息系统设计

摘要

Integrated platform for smart grid (IMS) monitoring system store massive, multi-source GIS grid information problems, the use of network-aware distributed information storage system as a way to network-aware subsystems for IMS monitoring system provides network-aware information inquiry service. The GIS Geographic Information Network in the perceptual information based on different characteristics into dynamic information and static information, use the information to build distributed network-aware storage systems in the cluster based on non-relational database Cassandra. Finally, and system performance test results show that:read four switches under traversal ask 20 nodes as the amount of data increases, the match time consumed increases.%针对智能电网一体化平台(IMS)监管系统存储海量、多源的GIS电网信息问题，采用分布式网络感知信息存储系统作为网络感知的子系统的方式，为IMS监管系统提供网络感知信息的查询服务。把GIS电网地理信息中的感知信息根据不同的特点划分为动态信息和静态信息，利用基于非关系型Cassandra数据库构建分布式网络感知信息存储系统集群。最后并对系统进行了性能测试，结果表明：4台交换机下的读取遍历询问20个节点随着数据量增大，匹配消耗的时间随之增加。
