Power grid model splicing method based on unified coding

Abstract

The invention discloses a power grid model splicing method based on unified coding, which is used for splicing power grid models in all regions and comprises the following steps of: (1) respectively establishing a data storage in each region and storing subregional power grid model data in each region into the data storage in a normative way; (2) dividing a boundary according to scope of jurisdiction, carrying out unified coding on equipment according to the scope of jurisdiction and the boundary, and arranging a coding server in each subregion, wherein the coding server is used for inquiringthe code of a data object in each subregional power grid model; and (3) acquiring regional power grid models according to the scope established on the basis of boundary division and splicing the subregional power grid models through unified coding. In the invention, both the generality and the expandability of the power grid model splicing method can be guaranteed, the model splicing can be carried out on line on the basis of a GDA (General Data Access) interface of the power grid model in each region, models to be spliced need not to be read into a buffering region in advance in a splicing process, the fewer resources are occupied, and the power grid models in multiple regions can be spliced simultaneously.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to a grid model splicing method based on unified coding. Background technique [0002] Over the years, affected by the characteristics of the wide-area distribution of the power grid, the production management of the power system divides the power grid into multiple subnets in layers and blocks according to the characteristics of the distribution area of ​​the power grid and the voltage level of the power grid, and forms a set of "Unified scheduling, layered management" management system. Under this system, the power grid is first divided into multi-level dispatch centers according to electrical characteristics such as voltage levels, such as: national dispatch, network dispatch, provincial dispatch, local dispatch, county dispatch, etc.; The region divides the same level of power grid into multiple dispatch centers, and each dispatch center establishes and mainta...

Problems solved by technology

Such a solution needs to manually establish several mapping tables and connection tables. If the device identification changes, these tables need to be maintained again, which makes it difficult for the solution to be automatically spliced ​​online; on the other hand, the solution requires a large amount of memory and cannot splice multiple The speed of the power grid model in one region is also very slow; moreover, the power grid model spliced ​​by this scheme is equivalent to copying a power grid model in one region and adding it to another model, the copied power grid model is identical to the source grid The model uses a different logo, which is inconvenient for correspondence and incremental update
