Problems solved by technology

Due to the invisibility of the loop, it is difficult for substation operation and maintenance personnel to locate and troubleshoot the abnormal message communication caused by the failure of secondary devices and network equipment; the existing message recording products and solutions lack The information interaction process between IED devices is displayed in a graphical way, which brings a lot of difficulties to technical personnel, especially technical personnel with experience in traditional substation operation and maintenance background, in terms of understanding, operation, fault analysis and positioning, etc. It is conducive to the rapid diagnosi

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] like figure 1 As shown, this embodiment provides a graphical expression method based on transmission analysis, which completes the transmission analysis among line protection, intelligent terminal, merging unit, busbar protection and background, and expresses it graphically, including the following step:

[0033] Step S1: analyzing the SCD file to obtain SCD information;

[0034] Step S2: Classifying, storing and indexing the analyzed SCD information;

[0035] Step S3: Access the substation data and analyze it;

[0036] Step S4: Express the analyzed data graphically.

[0037] In this embodiment, the step S1 is specifically: according to the schema, use the JAXB JAVA library to parse the SCD file, and the parsed content includes IED, data set, Inputs, DO, DA and description information for graphical display Extract the relevant information neede

Abstract

The invention relates to a transmission analysis-based graphical expressing method. The transmission analysis-based graphical expressing method comprises the following steps of S1, analyzing an SCD file to obtain SCD information; S2, performing sorting and storing on the analyzed SCD information to establish index; S3, connecting substation data and analyzing the data; and S4, performing graphical expressing on the data obtained by analysis. By adoption of the transmission analysis-based graphical expressing method, virtual secondary loop graphical form and secondary loop restoration can be realized; in addition, an interaction process of a whole event can be described exhaustively in a dynamic form through a progressive expressing way, so that checking of the event and verification of the secondary loop can be performed conveniently, and quick fault positioning by an operation and maintenance staff can be realized conveniently.
