Graph multi-version dynamic storing and publishing method for electric power system

Abstract

The invention discloses a graph multi-version dynamic storing and publishing method for an electric power system. The method comprises the following steps: (1) importing a graph and a model by using a graph model maintenance tool, and downloading a graph information table to form a current graph file set and graph maintenance information; (2) manually creating a model version number, and establishing a graph version storage identifier by the graph according to the current model version number; (3) editing the graph for maintaining, storing the graph in a network after the editing is completed, updating the graph information table by the graph, and storing a graph file to the current graph version storage identifier of a file server; (4) before the graph is published, comparing the versions of the graph and the model to ensure the integrity of the graph version; (5) performing graph verifying according to a graph verifying rule; (6) after the graph and the model are verified, putting the graph and the model on line formally. According to the method disclosed by the invention, the graph model maintenance task integration is ensured; the graph model maintenance supporting capacity, the practical level of a plurality of versions of the graph and the model and the graph version accessing efficiency are improved; therefore, the graph multi-version dynamic storing and publishing method for the electric power system has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching automation, in particular to a multi-version dynamic storage and release method for large power grid future state graphics for UHV construction. Background technique [0002] With the advancement of UHV construction and the further deepening of the application of smart grid dispatching control systems, each application module puts forward higher requirements for the grid model and graphics that are the basis for the safe and stable operation of the grid. At present, the smart grid dispatching control system provides a better method for maintaining the current model of the power grid. There have been many studies on the multi-version management method of the power grid model based on the full model and the difference model. The multi-version management method of the power grid model of the model, which divides the space dimension and application dimension model into corresponding ver...

Problems solved by technology

However, graphs are an indispensable tool for visual display of device topology connections, graph maintenance and model maintenance are equally important, but there is little research on graph multi-version management methods

[0003] In the current smart grid dispatching control system, the storage and release of the graphic version still adopts the full graphic set management method. With the continuous increase of the grid scale, the graphic files continue to increase. Each graphic version change is only a partial update, and the full graphic set is used. The management method will lead to many redundant graphics files, which will have a great impact on the consumption of storage space and the storage and release efficiency of the whole graphics.

Moreover, the maintenance of multiple versions of graphics is relatively independent, there is a lack of linkage between graphics and models, and there is no effective technical support for unified maintenance of multiple versions of graphics and models
