Abstract
The overall framework and operation logic of an EMS-based network automatic switchover system are introduced in detail in this paper. The system gets the information of power grid by reading the XML file, confirms the composition of the substation equipment and the bus line connection mode, uses the modeling tool to manually define the self cast operation model, establishes the data platform according to the IEC61970/CIM rule, and forms the real time data mapping; When the fault occurs, the 104 protocol is used to obtain the remote information, telemetry and protection action information of EMS. Based on the above real-time information, the operation object is searched to confirm the operation parameters, and a self-investment plan is automatically generated according to the judgment logic. The operation interface is displayed in an SVG vector diagram. It is of great significance to quickly restore power supply and improve the security of smart grid.
