Research on Integration Technology Between Distribution Automation System and Geographical Information System

With the rapid development of the construction of the distribution automation system (DAS), how to integrate DAS with existing application system is a primary problem to solve, especially with geographical information system (GIS). This paper investigates various current integrated technologies between DAS and GIS and researches a system integration approach based on common information model (CIM) in detail. The results obtained from a practical project prove that the system integration technology base on CIM is effective, cost small and fast although it is not suitable for real-time application.
