Digitized transformer substation

Abstract

This invention discloses a digitized transformer substation, comprising primary equipment, secondary equipment and operation management equipment, wherein the primary equipment is connected with the secondary equipment through an optical cable; devices of the secondary equipment are connected mutually through Ethernet; and the secondary equipment is connected with the operation management equipment through the Ethernet. The digitized transformer substation disclosed by this invention uses a structure that the primary equipment is connected with the secondary equipment through the optical cable and the devices of the secondary equipment are connected through the Ethernet, thus, the digitized transformer substation is constructed and maintained conveniently; the structure also avoids the digitized transformer substation generating a plenty of repeated data acquisition on the secondary equipment, thus, system resource is saved; an information transmission method in the digitized transformer substation is simplified so that smooth interconnection and intercommunication can be realized between the equipment as well as between the equipment and the systems; the information of the digitized transformer substation can be utilized comprehensively without causing information island; and information sharing level is high.

Description

technical field [0001] The invention relates to the technical field of power transformation equipment, in particular to a digital transformation substation. Background technique [0002] The digital substation takes the primary and secondary equipment of the substation as the digital object, and based on the high-speed network communication platform, realizes information sharing and interoperability through the standardization of digital information, and realizes relay protection and data management based on network data.
