An application method for user-defined configuration files of IED equipment in intelligent substations

Abstract

The present invention relates to an application method for an IED user customized configuration file of an intelligent transformer substation. The intelligent transformer substation comprises a substation control layer device and a process layer device. The method adopts the implementing mode that: firstly, aiming at different functions of an IED, extracting related configuration information of communication between the IED and the devices in the substation from an IEC61850 standard configuration file; and secondly, establishing a mapping relationship between the IEC61850 standard configuration file and IED application function information and forming the IED customized configuration file for the IED to directly read, analyze and apply. According to the application method, the implementing mode of an IEC61850 standard in the IED is simplified, the analytic modeling efficiency of an IED application configuration file is improved, and the debugging period of the IED is shortened.

Description

technical field [0001] The invention relates to the field of power distribution and substation automation of smart grids, in particular to an application method for user-defined configuration files of IED equipment in smart substations. Background technique [0002] At present, the IED equipment in the smart substation generally uses the IEC61850 communication protocol to realize the information exchange between the equipment in the substation and between the substations. In order to realize the configuration function of system communication in the substation, domestic and foreign electric power companies have successively developed their own configuration tool software. The configuration file generated by the configuration tool using the substation configuration description language SCL (Substation Configuration description Language) generally needs to be analyzed and constructed in the project. mold. Since the IEC61850 standard has not yet standardized the modeling detail...

Problems solved by technology

Since the IEC61850 standard has not yet standardized the modeling details of all functions of various types of equipment, the understanding of the standard by various manufacturers is not completely consistent, and it is easy to have ambiguity in the understanding of the data structure during the analysis and modeling process, which brings difficulties to the joint debugging of manufacturers , and sometimes even need to modify the program to adapt to different projects; the project site sometimes temporarily adjusts the wiring or increases or decreases the amount of access, each modification requires professionals to change the configuration file and then re-analyze the model, the management operation is complex and inefficient And prolong the debugging cycle, but also increase the workload of the debugging personnel

In addition, the 61850 configuration file itself has a lot of content, and it takes a long time to parse and read, which also leads to the application of the IEC61850 standard protection measurement and control and other secondary equipment that requires fast response. The start-up time is longer than traditional protection measurement and control equipment. many main reasons
