Electric power communication protocol extension-based master substation remote programmed control method

Abstract

The invention discloses an electric power communication protocol extension-based master substation remote programmed control method. On the basis of a power grid dispatching control system, the system comprises an intelligent substation master station and an intelligent substation sub-station, wherein the intelligent substation sub-station comprises a data communication gateway machine, a substation monitoring system, one or more measuring and control devices and one or more protection devices; the intelligent substation sub-station and the intelligent substation master station are in cooperation to achieve a remote programmed operation function; the intelligent substation master station does not need to store a programmed operation ticket and summons a programmed control object of the intelligent substation sub-station through the data communication gateway machine; the programmed operation ticket is stored and maintained in the substation monitoring system; and the data communication gateway machine takes charge of generation and pushing of the station end programmed control object, analysis of the operation ticket, decomposition execution of programmed operation, interaction of operation process information and pushing of an equipment state. The master substation remote programmed control method meets the program control requirements between the master station and the sub-station; and the dispatching level of a power system is improved.

Description

technical field [0001] The invention relates to a remote programmed control method for master and substations based on the extension of electric power communication protocols, belonging to the field of power grid dispatching systems. Background technique [0002] At present, the smart substations that have been put into operation generally have the program control function, and the relevant technical specifications of the smart grid dispatching technical support system have also put forward clear and specific requirements for the program control, requiring the substation to receive and execute the program control of the control center. The control instructions and the operation interface should be visualized, etc., but the telecontrol protocol between the master and sub-stations cannot meet the needs of programmatic control between the master and sub-stations. The operation ticket is the basis for the master station and the slave station to identify and start the programmed ...
