GIS-based Inspection System for Voltage Distribution
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.
