Method for automatically dividing isolation by protection signal, and modeling tool

Abstract

The invention provides a method for automatically dividing isolation by protection signals, and a modeling tool, which belong to the technical field of information management methods of electric powersystems. Before the matching of the protection signal and the isolation, the accuracy of the isolation scope and the isolation type can be ensured as far as possible, and a better matching effect canbe guaranteed. The naming detection on the protection signal can detect the protection signal that does not accord with a power grid unified naming standard, and the matching accuracy and efficiencyof the isolation of the protection signal can be improved. The matching between the protection signal and the isolation can be conducted based on the rule base of intelligent matching isolation, and thereby the accuracy and reliability of the isolation dividing by the protection signal can be improved. The matching result is stored in the database, which is convenient for the taking of the position relationship between the protection signal and the isolation at any time. Moreover, one-key matching or manual matching of the protection signal and the isolation can be realized, and the work quantity of labor maintenance can be reduced, and the work efficiency and power grid operation level of experts can be improved.

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
