Automatic conversion method for station primary wiring diagram model

Abstract

The present invention discloses an automatic conversion method for a station primary wiring diagram model. The method comprises the following steps: step S1, reading a wiring drawing file, and reading graphic data of a wiring drawing; step S2, traversing the read graphic data, analyzing a characteristic of device graph elements, and establishing a mapping relationship between a device graph element and a standard graph element; step S3, recognizing a connecting relation between the device graph elements, and establishing a device relation matrix; and step S4, according to the mapping relationship and the device relation matrix, generating an SVG vector graphic file. The method disclosed by the present invention solves the problems of diversity and complexity of drawing management and reduces the system capacity occupied by drawing storage to the largest extent.

Description

technical field [0001] The invention relates to the field of power system scheduling automation, in particular to a method for automatically converting and storing a main wiring diagram model of a power system station. Background technique [0002] The main wiring diagram of the power grid plant is a graphical representation of the relationship between power generation, transmission, transformation, power distribution and topology structure described by the power grid. It has been widely used in the management, analysis and calculation of the power system, and has become An important aid in management. [0003] At present, the review of on-site drawings of power grid plants and stations mainly collects site drawings (including *.dwg, *.dxf, *.vsd, *.xml, *.dwg, *.dxf, *.vsd, *. .scg, *.sck, etc.), and then design and edit through the corresponding tools; send the modified plant site drawings to the site through DMIS or email for confirmation and completion of review.

Problems solved by technology

During this process, the scheduling center has a heavy workload for modifying the on-site drawings, and there is no unified storage and management of the wiring diagrams; in addition, in the current SCADA (Supervisory Control And Data Acquisition Data Acquisition and Monitoring Control) system, due to different design specifications of different manufacturers, resulting in The representation of the wiring diagram is not the same as the content of the display, and it cannot meet the management requirements of the dispatch center for the start-up simulation of new equipment.
