Abstract: This invention discloses a CIM/E (Common Information Model) and CIM/G-based graphics-model-integrated apparatus and method for distribution network. The apparatus comprises an operating system for distribution systems, which is used by distribution network dispatcher and a debugging system for maintaining graphics and models. The operating system communicates with the debugging system via TCP/IP protocol, using the CIM/E Language to describe full models and incremental models of distribution network, and using the CIM/G Language to describe graphics of distribution network. This invention manages the graphics and models through the remote call, graphics-model-operation and graphics-model-rollback, achieves the management of the graphics and models of past, present and future.
