Action report visualization display method based on common format for transient data exchange (COMTRADE)

Abstract

The invention provides an action report visualization display method based on a common format for transient data exchange (COMTRADE). An action report is finally presented in a WORD form through extending information name namespace of a header file (HDR file), using different characters to carry out identifier classification, and carrying out data and format conversion on the HDR file of an ASCII text file. The method will bring great convenience to remote analysis, evaluation and simulation of a power system and protection and control thereof under the circumstance of fault disturbances. According to the method provided by the invention, a large amount of data comparison and format optimization are carried out, achieving the same effect with serial printing display of a protection device is finally realized, and an output action report file can satisfy requirements of power system accident analysts. The method can be transmitted and used among different application systems of WINDOWS, LINUX and the like, and has a higher practical value for power system fault report analysis.

Description

technical field [0001] The invention belongs to the technical field of automatic analysis of electric power systems, in particular to localization of substation protection equipment, and a method for remote fault report analysis and wave recording graphics display. Background technique [0002] The substation is an indispensable and important link in the power system. The reliability of the relay protection equipment plays a decisive role in the safety and economic operation of the power grid. After the protection action of the traditional substation, some protection information can be sent to the remote end through the header file HDR file of the wave recording file. However, the HDR file adopts ASCII format and the language is XML (eXtensible Markup Language) encoded by Unicode. The purpose is to transmit data, not to display data. Only relying on the header file sent to the remote end by protection cannot obtain enough data to fully analyze the accident. It is necessary t...

After the protection action of the traditional substation, some protection information can be sent to the remote end through the header file HDR file of the wave recording file. However, the HDR file adopts ASCII format and the language is XML (eXtensible Markup Language) encoded by Unicode. The purpose is to transmit data, not to display data. Only relying on the header file sent to the remote end by protection cannot obtain enough data to fully analyze the accident. It is necessary to rush to the scene to call and print the protection action report and wave recording file on the spot. Some The substation is located in a remote area, and it is time-consuming and labor-intensive to go to the site once, and it is impossible to obtain accurate reports and wave recording data of power system faults at the first time, which brings great inconvenience to power system maintenance personnel. Accurately acquire and display the detailed report and wave recording data of the protection device action in a timely manner, which becomes a necessary part of the development of the present invention
