Access method and system between main and sub-stations of power grid

Abstract

The invention relates to a method and system for accessing between main and sub-stations of a power grid. The method comprises: the services provided by the transparent access server of the sub-station are registered on the global service manager in advance; based on the service registered by the transparent access server of the sub-station, The transparent access server of the substation receives the data service request sent by the dispatching center through the real-time transparent access server of the main station; the transparent access server of the substation searches the requested data from the virtual data pool according to the received data service request, and sends The found data is returned to the master station, and at the same time, the transparent access server of the master station returns the data to the dispatch center business application. The access method and system between the main and sub-stations of the power grid provided by the present invention solves the problem that the content transmitted by the substation is limited to "four remote" data, which causes the bottleneck of data usage between the upstream substation and the downstream control center, and is sufficiently complicated. Large power grid operation analysis and accident analysis provide all types of data support.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching automation, and in particular relates to an access method and system between main and sub-stations of a power grid. Background technique [0002] Reliable data interaction between the main and sub-stations of the power grid is an important guarantee for the stable operation of the dispatching and substation systems. With the advancement and deepening of the construction of smart substations, more new technologies and new equipment have been adopted in smart substations. The data interaction requirements between the master and sub-stations have developed from the initial simple "four remotes" to remote browsing and direct transmission of alarms. At the same time, the data interaction between control centers has also developed from simple data forwarding to a complex data exchange model represented by remote access. [0003] The traditional power grid data is forwarded step by st...

Problems solved by technology

[0004] In order to solve the problem that the content transmitted by the above-mentioned traditional substation is limited to "four remote" data, which has caused a bottleneck in the use of data between the upstream substation and the downstream control center, a large amount of data in the substation except the "four remote" is stranded in the station, and it is difficult to provide sufficient data support To deal with the problems of complex large power grid operation analysis and accident analysis, the present invention provides a method for accessing between master and sub-stations of the power grid. The method includes:
