A method and modeling tool for automatically dividing intervals of protection signals

Abstract

The present invention relates to the technical field of information management methods of electric power systems, and more specifically, relates to a method for automatically dividing intervals of protection signals and a modeling tool; the corresponding parameter preparation work of the present invention should be done as soon as possible before the matching of protection signals and intervals It is possible to ensure the accuracy of the interval range and interval type, and to ensure better matching effects; the naming detection of protection signals can detect protection signals that do not conform to the unified naming specification of the power grid, and improve the accuracy and efficiency of protection signal interval matching; The rule base of the matching interval matches the protection signal and the interval, which improves the accuracy and reliability of the interval division of the protection signal; the matching result is stored in the database, which is convenient for the configuration relationship between the protection signal and the interval to be retrieved at any time; in addition, the present invention can One-key matching or manual matching of protection signals and intervals can reduce the workload of manual maintenance and improve the work efficiency of professionals and the level of grid operation and maintenance.

Description

technical field [0001] The present invention relates to the technical field of information management methods of power systems, and more specifically, to a method for automatically dividing intervals of protection signals and a modeling tool. Background technique [0002] With the continuous improvement of the automation level of the power system, various types of protection signals are connected to the dispatching automation system. The number of these signals is very large, and the corresponding maintenance work is also very heavy. At present, a large number of protection signals of these various and large secondary equipment are uploaded to the power dispatching automation system, and the master station side imports its parameters into the system through tools. These protection signals cannot correspond to the model of the scheduling automation system, so these corresponding operations need to be completed manually by the automation maintenance personnel. For a single su...

Problems solved by technology

[0003] However, in traditional power systems, the grid and substations are usually modeled separately, and the management, maintenance and use of the models are very difficult, and due to the heavy modeling workload and the lack of efficient modeling methods, often only individual substations are modeled. The detailed modeling of primary and secondary equipment cannot meet the needs of building control integration

In addition, in traditional model maintenance tools, a large part of the work is still done manually, which inevitably hinders the realization of automation, standardization, and standardization of substation information model management; the existing primary and secondary equipment associations It still cannot meet the model requirements of advanced applications such as anti-mislocking and intelligent alarms. In order for these applications to be used normally, automated operation and maintenance personnel are usually required to reconfigure the existing application analysis models
