中文摘要	An external network equivalent model must follow the change of operation modes of the external network in order to ensure computing precision of EMS application software in area network control center. To improve the practicability of EMS software in area network control center, a new system, which can automatically create an online external network equivalent model for EMS/DTS usage of area networks, is realized. According to IEC6I970 CIM standard, the system gets the whole network model and its real-time data from the existing EMS of provincial control center, then the system automatically creates an external network equivalent model and sent to area control centers by WAN according to IEC61970 CIS/CORBA standard for further use of area network control center EMS/DTS. External network model can be flexibly made in the equivalent system. Partial buffer system in the external network can be set up automatically or selected manually to balance the equivalent calculation precision and speed. This system runs automatically in online mode, and provides external network equivalent model and corresponding real-time data all the time for area network. This system has been put into practical operation and the operation results show that the correctness of EMS/DTS calculations in area control center is greatly improved by this equivalent system.
