Method and system for identifying primitives of power system diagram of plant station and computer readable medium

Abstract

The invention relates to a plant station electrical system diagram primitive recognition method and system and a computer readable medium. The primitive recognition method comprises the steps of obtaining electrical system diagram primitives and a plant station electrical system diagram to be recognized; constructing and using the power system diagram primitives to train a power system diagram primitive recognition and classification model of the plant station; and inputting the plant station power system diagram into the trained plant station power system diagram primitive identification classification model to obtain a primitive identification result. Compared with the prior art, the method has the advantages of high accuracy, good effect and the like.

Description

technical field [0001] The invention relates to the technical field of smart grids, and in particular, to a method, system and computer-readable medium for identifying a graphic element of a power system diagram of a power plant. Background technique [0002] The single-line drawing of the plant and station is closely related to the integration of smart grid planning, construction and transportation, and is the premise for the realization of a high degree of integration between the substation automation system and dispatching SCADA / EMS. The drawing methods of the plant station one-line diagram mainly include computer-aided manual drawing and computer-executed automatic drawing. Due to the lack of uniform standards in terms of model, data, layout and graphics, it is impossible to use a single program to edit (for example: modify, reconstruct) the multi-source plant single-line diagram with "inconsistent diagram modulus". [0003] At this stage, the identification of electric...

Problems solved by technology

However, manual drawing must follow uniform business rules (standards), which makes the "new model" and "old model" may have undiscovered common features. How to effectively mine common features is a key problem to be solved

At the same time, it will be of great practical significance to optimize the problem that the image background of the power system diagram of the plant and station is blurred and the rotation angles of the graphics elements are inconsistent, which leads to the difficulty in identifying the graphics elements of the power system diagram.
