Method for automatically generating wiring diagram of power network plant substation

Abstract

The invention discloses a method for automatically generating a wiring diagram of a power network plant substation. The method comprises the steps of reading a primary model of the power network plant substation; generating a topological connection relationship between a database and a primary device so as to judge out a voltage level and a wiring mode of the wiring diagram of the power network plant substation, and according to the voltage level and the wiring mode of the wiring diagram of the plant substation and the settings of a user to regional customs and specifications, selecting a corresponding automatic diagram generation algorithm; performing arrangement and connection on graphic elements of the primary device, and performing color and tagging configuration; automatically associating the primary device on a canvas with an object in the database according to a device name; and recording modification of the user to the generated wiring diagram of the plant substation, and updating the modification to a template for updating the wiring diagram of the power network plant substation next time. According to the method, the generation efficiency of the wiring diagram of the power network plant substation can be improved; different voltage levels and various wiring modes can be adapted; the color and tagging configuration is automatically finished, so that secondary configuration of the user is reduced; and therefore, the updating process for automatically generating the wiring diagram of the plant substation is realized.

Description

technical field [0001] The invention relates to the field of electric power automation, in particular to a method for automatically generating wiring diagrams of power grid plants and stations. Background technique [0002] The essence of power plants and substations is that electrical primary equipment realizes the transformation and transmission of electric energy through electrical connections. The wiring diagram of the plant station reflects the function of a single electrical equipment and the combination of electrical equipment, that is, the function of power system resources, in a higher and more comprehensive graphical way. . As the scale of the power grid continues to expand, the topology of the station end becomes increasingly complex, and the workload of making digital grid graphics for the corresponding automation and information systems also increases significantly. At present, the wiring diagrams of power grid plants and stations are still mainly drawn by hand...

Problems solved by technology

One direction of research is to directly import the graphics of external systems, for example, when making the total station system configuration file SCD or the common information model CIM, add scalable vector graphics SVG at the same time. It cannot be guaranteed to be completely consistent, so the imported graphics cannot be used directly, and it will take a lot of time to adjust according to regional usage habits and specifications in the later stage, and the generation efficiency is not significantly improved

Another direction of research is automatic generation. At present, the existing methods are all improvements of the previous layout algorithm. After testing, they cannot be applied to the actual system. After analysis, this is because the layout of the same plant and station wiring diagram is restricted by regional usage habits and regulations. There are many changes in the way. For example, the "Substation Monitoring System Graphical Interface Specification" of the State Grid Corporation of China stipulates that "the interval order of the main equipment of the same voltage level should be in accordance with the actual interval order on site", and the algorithm alone cannot meet this demand.

In addition, the current automatic generation method of plant wiring diagram ignores the automatic generation of equipment labeling, equipment color configuration, text color, text font, etc., and only pays attention to the layout of equipment and the connections between them

Therefore, the current automatic generation method of plant wiring diagram still needs a lot of time for secondary processing, resulting in low production efficiency

In addition, whether it is to directly import the graphics of the external system or the existing automatic generation method, there is no clear update process

If the user makes secondary adjustments after the wiring diagram of the plant and station is made, these secondary adjustments will be lost after regeneration, resulting in additional repetitive work
