Power grid operation panorama model extension method and system

Abstract

The present invention provides a method and system for extending a panorama model of power grid operation. The method includes the steps of: receiving an extension instruction, searching for an application module corresponding to an application module identifier in the extension instruction in a preset extension area; An extension table is established in the application module; the attribute identification is received, and the attribute corresponding to the attribute identification is expanded in the extension table according to the attribute identification, because the extension table is established in the extension area, and the attribute extension is performed in the extension table , and the system operation is based on the models and data of the public area and the application area. Modifications in the "extension area" will not affect the normal operation of the system, and online expansion is realized, which not only ensures the standardization of the grid operation panorama model, but also makes The panorama model of power grid operation can meet the needs of practical applications.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for extending a panorama model of power grid operation. Background technique [0002] With the continuous expansion of the scale of the power grid, the workload of power grid monitoring and operation and maintenance is increasing. Each major has established its own information dispatching system, such as: dispatching automation system, protection information system, security system, equipment monitoring system, water dispatching system, etc. system, lightning monitoring system, icing monitoring system, etc. These professional systems are part of the power information dispatching system, providing professional data for production, evaluation, analysis, maintenance, etc. In the past, each professional system was built independently to serve this specialty, and it was unable to provide cross-disciplinary panoramic data, forming an island phenomenon of di...

AI Technical Summary

Problems solved by technology

[0004] When extending the panoramic model of power grid operation, the attributes corresponding to the application modules are extended, and the application modules are models based on professional systems. Since there are many professional systems integrated in the panoramic model, if the attribute information is expanded each time Expansion, disconnecting the corresponding production system will seriously affect the normal operation of the power grid and destroy the stability of the power grid operation; and because the expansion requirements of the professional system integrated with the panoramic model are also diverse, the expansion means are not uniform, increasing the Increases the complexity of expansion and reduces the efficiency of expansion
