Method and system for detecting visualization and configuration consistency of configuration file of intelligent substation

Abstract

The invention discloses a method for detecting visualization and configuration consistency of a configuration file of an intelligent substation. The method comprises the following steps: 1) viewing an SCD file; 2) comparing the SCD file: performing imaging comparison, primarily reporting an error in a topological graph when different versions of loops or inconsistent message parameters are detected, then reporting the error in details on a detailed virtual secondary loop diagram and displaying the loop or terminal change, and finally, listing the configuration change of the compared SCD file; 3) debugging strategy and verifying by the SCD file: a) generating a corresponding debugging strategy according to a comparison result, and b) verifying the related IED device according to the debugging strategy, thereby checking the correctness of the loop and maintaining the consistency of the practical information and SCD file description between the in-station intelligent devices of the intelligent substation. The reliability of information interconnection between the IED devices is guaranteed; the invisible hidden danger of the safe running of a power grid is eliminated; the systematic and targeted properties of the debugging work of the intelligent substation are increased; and the debugging period of the intelligent substation is effectively reduced.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of intelligent substations, and relates to a method and system for visualizing configuration files of an intelligent substation and detecting configuration consistency. [0003] 【Background technique】 [0004] The SCD file is the smart substation configuration description file. This file fully describes the primary and secondary electrical connection relationship and communication logic relationship of the substation through a standardized data model. It can be called the primary and secondary electrical design drawings of the substation in text file format. But in my country's current smart station construction, due to the lack of a unified management monitoring system and means. This file can be frequently modified by multiple parties according to their needs during the construction of the intelligent station, and the final possible result is: [0005] 1. Because the SCD file itself is a text file format, i...

AI Technical Summary

Problems solved by technology

[0005] 1. Because the SCD file itself is a text file format, its readability is relatively poor, due to the difference in the level of different update personnel and possible negligence, it is difficult to guarantee the correctness of the frequently updated SCD file;

[0006] 2. The SCD file and the device instantiation upgrade are not synchronized and inconsistent, which affects the interconnection between devices and leaves unknown safety hazards for the later operation of the substation;

[0007] 3. SCD files are frequently updated, and device instantiations are frequently updated, resulting in disorderly and repetitive debugging work

It is difficult to ensure the quality of project commissioning, which has also become the primary factor affecting the commissioning and construction period of substations
