Problems solved by technology

[0003] However, the change and modification of the model configuration directly affects the correctness of the secondary system operation. When the smart substation is rebuilt or expanded, the SCD file will undergo corresponding configuration changes. Therefore, the traditional cable wiring inspection and the judgment method of the influence cannot be accurately determined. The problem of smart substation upgrade device and affected device, at the same time, the above method also has the problem of long detection time

Abstract

The present invention provides an intelligent delineation system, method and intelligent substation, which relate to the technical field of intelligent substations. After importing the new SCD file and the reconstruction and expansion SCD file of the intelligent substation through the presentation layer, the persistence layer can be used in the new SCD file and the modified SCD file. The device information and virtual circuit connection information are extracted from the expanded SCD file, and then the business layer determines the upgrade device and affected device of the smart substation based on the above device information and virtual circuit connection information, realizing the automatic delineation of the smart substation upgrade device and affected device , which effectively alleviates the problem that the traditional cable wiring inspection and spillover judgment method cannot accurately determine the smart substation upgrade device and the spillover device, and at the same time shortens the detection time.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to an intelligent delineation system, method and intelligent substation. Background technique [0002] With the comprehensive application of IEC61850 in smart substations and the development of digital and network technologies, the secondary circuit of relay protection has changed from conventional cable hard wiring to digital information flow carried by "invisible" and "intangible" optical fibers. The circuit connection between the equipment is realized in the substation SCD (Substation Configuration Description, the overall station system configuration file), each secondary device is modeled, and the network trips, protections and five-proof interlocking GOOSE (Generic Object Oriented Substation Event, general object-oriented substation event) signal and SV (Sampled Value, sampling value) information and other secondary virtual circuits are reflected in the model. ...
