基于GIS技术的电压分布监视平台

GIS-based Inspection System for Voltage Distribution

传统的电力变电站以及主站监控系统一般以统计图表或曲线的方式监视电压变化,而不具备直接提供电压时空分布信息的功能。对此,提出了一种基于GIS(地理信息系统)技术的电压时空分布可视化方案,通过构建平台层、数据服务层和应用层,以及解决电压分布二位插值、多线程加速历史回放、融合建模与厂站维护等关键问题,实现可按电压等级分层的电压地理分布实时展示、区域电压变化历史回放、厂站信息及时维护等功能。该系统在提升主站系统现有数据利用率的同时,可为运检人员提供直接有效的区域电压实时分布和历史变化信息。

Conventional power substation and main station monitoring systems generally monitor voltage changes in the form of statistical charts or curves,while inadequate in directly providing information on voltage spatiotemporal distribution.A voltage spatiotemporal distribution visualization scheme based on GIS(Geographic Information System)technology has been proposed in the present work.By constructing a platform layer,data service layer,and application layer,as well as solving key problems such as voltage distribution two-dimensional interpolation,multi-threaded acceleration of historical playback,fusion modeling and station maintenance,the scheme can achieve real-time display of voltage geographic distribution stratified by voltage level,historical playback of regional voltage changes,and timely maintenance of plant information.This system not only improves the existing data utilization of the main station system,but also provides direct and effective real-time distribution and historical change information of regional voltage for operation and inspection personnel.
