Problems solved by technology

This method needs to maintain status information, commissioning and decommissioning time information for all equipment objects in the power grid, which will bring a huge workload to the maintenance personnel of the power grid dispatching system, especially when the power grid is in a period of rapid development. Today, when the project is put into operation and the scale of the power grid continues to expand, this kind of maintenance work is even more difficult to maintain

Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The multi-version management method of the power grid model based on the model set and the difference model provided by the present invention realizes the multi-dimensional and multi-version models of the space, time and business applications used by the business applications of the power grid dispatching control center through the unified management of the multi-version of the power grid model Set (difference model) storage, loading, browsing, maintenance, verification, merging, putting online, conversion and release and other unified management functions, and finally meet the needs of various business applications in the power grid dispatching control center for multiple versions of the model. Its core is to divide the space dimension and application dimension model into corresponding versions for management thro...

Abstract

The invention relates to a management method in the technical field of the automation of a power system, in particular to a multi-version management method for a model set and difference model-based power grid model. The method comprises the following steps of: 1) expressing a difference model; 2) storing the model; 3) loading the model; 4) browsing the model; 5) merging the model; 6) checking the model; 7) transforming the model; and 8) carrying out the on-line distributing and putting of the model. The method divides a space-dimensional model and an application-dimensional model into corresponding versions through the type of a model space and a model tree, and takes the model set as a base wire to realize the multi-version management of the model time dimension by overlapping the modes which become effective at different times.

Description

technical field [0001] The invention relates to a management method in the technical field of electric power system automation, in particular to a multi-version management method of a power grid model based on a model set and a difference model. Background technique [0002] In the current power grid dispatching automation system, the version management of the model is only limited to the management of the time dimension change information of the power grid model. There are two main ideas. The simplest method is to save the changed power network model information and all graphic information in the form of files to form a full model version of the power grid corresponding to a certain moment. However, as the scale of the power grid continues to increase, the size of the full model version file of the power grid is also increasing. If the full model of the power grid is saved every time, it will bring greater pressure on the disk storage space. Moreover, each change of the po...
