Study On Development Of Transmission Line Condition Monitoring GIS Platform

Status monitoring of transmission line is an important means to achieve transmission linemaintenance, to enhance level of management. It is related to the efficiency and security ofpower grid operation. The existing status monitoring of transmission line usually representinformation by dry figures, Difficult to meet the growing needs of visual management.In this study, utilize features and advantages of RS and GIS technology, takemulti-source geographic data and spatial data model as a core, use interaction of2D and3Dmap, catenary model, automatic layout of3D model, seamless integration of thematicinformation and other key technologies to solve the problems of traditional power GIS, tointegrate real-time monitoring information of transmission line. Establish an integrated GISplatform of2D and3D map to achieve the power business applications on the map.This study achieved the following results:1. Realize the integration of2D and3D map display and effective linkage.2. Realize drape simulation of the power wires.3. Realize the model automation layout in the three-dimensional scene.4. Realize a seamless integration of GIS and MIS.
