SCD file document check device for intelligent substation

Abstract

The invention discloses an SCD file document check device for an intelligent substation. The debugging and maintenance problems of the existing intelligent substation can be solved. The SCD file document check device is characterized by comprising an optical network port interface, an optical serial port interface, a message parsing module, a signal processing module, a liquid crystal, a USB interface and a keyboard, wherein the optical network port interface receives SV and GOOSE message signals; the optical serial port interface receives an FT3 message signal; the SV, GOOSE and FT3 message signals are subjected to message parsing by the message parsing module and are transmitted to the signal processing module; an SCD file is imported into the signal processing module by virtue of the USB interface; the liquid crystal provides a man-machine interaction interface; and the keyboard controls the operation interface and menu and inputs the digital alphabetic information. The device disclosed by the invention provides a powerful tool for SCD file check for the intelligent substation site, and the debugging efficiency of the intelligent substation is improved.

Description

technical field [0001] The invention relates to the technical field of commissioning, maintenance and testing of intelligent substations, in particular to an SCD file inspection device for intelligent substations. Background technique [0002] The SCD (SubstationConfigurationDescription, substation configuration description) file is used as the whole station configuration file of the intelligent substation, which is the unified data source of the whole station, and describes the instance configuration and communication parameters of all IEDs (Intelligent Electronic Devices, intelligent electronic devices), and the communication configuration between IEDs And virtual terminal interconnection information, etc., are of great significance to the design, commissioning, operation and maintenance of smart substations. [0003] At present, in the commissioning, testing, and maintenance of smart substations, the review of the SCD file format is not strict, and there are syntax and se...

AI Technical Summary

Problems solved by technology

[0003] At present, in the commissioning, testing, and maintenance of smart substations, the review of the SCD file format is not strict, and there are syntax and semantic errors. The IED model description does not follow the requirements of relevant standards, such as "Q / GDW396IEC61850 Engineering Relay Protection Application Model" and intelligent The "six unified" model of substation relay protection caused errors in the description of the SCD file model; during the commissioning of the smart substation, only the configuration of a certain IED device was modified and downloaded, and the download of other IED devices connected to it was ignored, resulting in IED Communication errors between devices; the actual model used by some IED devices is inconsistent with the description in the final version of the SCD file, resulting in the IED device not working properly or unable to communicate with other IED devices

The SCD files used in smart substations are written in XML language, and the SCD files of a substation have hundreds of thousands or even millions of lines of code, which makes the viewing and verification of SCD files a very cumbersome and time-consuming task

The above problems have brought many problems and difficulties to the on-site commissioning of smart substations
