Practical research on automatic graph and model exchange between GIS and DMS

摘要

In modern power distribution utility, GIS and DMS address the same physical network and share a great amount of data. Nowadays, most of them still exist as separate systems and on different platforms. With the continuing growth of data and evolution of the systems, it requires to establish interfaces and workflows between GIS and DMS for exchanging necessary data with a lower maintenance cost and, in another hand, to ensure data consistency. This paper presents the problems when generating single-line diagram (orthogonal maps) from GIS to DMS and the model exchange between GIS and DMS. DMS utilizes GIS information to automatic on-line generation of graphical representations for 10kV feeders. For a new DMS installation, it generates the single-line diagram to facilitate the SCADA functions. Considering topology of distribution network is under significant change subjected to civil projects and the growth of power consumptions, geo-schematics drawings in the GIS should be converted into single-line diagram to adapt to the distribution network operators and update the DMS in a specified period of time without manual interference. Finally, the management expectations, benefits of the graph and model exchange technologies are also discussed.
