Embodiment Construction

[0035] In the new generation of smart substations, the station domain protection and control device runs on the station domain protection layer, and can obtain station-wide information, such as the operating status of localized devices, SV (Sampled Value) messages, and GOOSE (Generic Object Oriented Substation Event) messages , using this information to judge the status of in-situ protection.

[0036] The present invention adds a message analysis module to the existing station domain protection, analyzes and judges the SV and GOOSE messages of the whole station obtained by the station domain protection control device, and realizes the monitoring of the process layer information of the whole station; and according to the message analysis results Judging the running status of in-situ protection, and adaptively switching on and off the station domain backup protection function. The combination of the two realizes the function of the station domain operation and maintenance suppor...

Abstract

The invention discloses a station territory operation and maintenance support platform. By the station territory operation and maintenance support platform, full-station sampled value (SV) messages and generic object oriented substation event (GOOSE) messages are monitored in a station territory protection control device, the running state of a local device is judged accordingly, and meanwhile, the related function of adaptively inputting and withdrawing station territory protection is achieved according to an analysis result. In the station territory operation and maintenance support platform provided by the invention, full-station information sharing can be fully utilized, the analysis result is combined with the function configured through station territory protection, thus, the station territory protection device has high applicability, the workload of site operation and maintenance is greatly simplified, and moreover, the power supply reliability and the relay protection rapidness of a power system are guaranteed.

Description

technical field [0001] The invention relates to a station domain operation and maintenance support platform based on a hierarchical relay protection structure of an intelligent substation and information sharing of the whole station, and belongs to the technical field of power system automation. Background technique [0002] According to the hierarchical protection design scheme of smart substation, the substation relay protection system is divided into three layers: local protection layer, station domain protection layer and wide area protection layer. Site domain protection can obtain the information of the whole station and realize the backup protection function of the whole station. [0003] The station domain protection control device has been widely used in the new generation of intelligent substations, mainly to realize the centralized backup protection function of the whole station, but does not make full use of the obtained information of the whole station. The con...
