Graphical intelligent transformer substation model design method based on computer-aided design (CAD)

Abstract

The invention provides a graphical intelligent transformer substation pattern design method based on computer-aided design (CAD), which is characterized in that two functional modules including a graphical edit module and a model edit module are arranged in the CAD; the graphical edit module is used for drawing a conventional drawing and expanding attribute definition functions; the model edit module is used for finally generating a model file and supporting the high-order functions of importing, exporting, editing and verifying files and the like; and the graphical edit module and the model edit module carry out sharing operation on model information by accessing an extensive makeup language (XML) database interface. In the graphical intelligent transformer substation pattern design method based on the CAD provided by the invention, by developing graphical model design software based on the CAD, the design and the system of the intelligent transformer substation are integrated, thus not only realizing to carry out first and second wiring diagrams of the conventional transformer substation in the design, but also finishing the complete data model configuration of the whole substation and data stream connection of the transformer substation according to the interface control document (ICD) model files provided by equipment manufacturers and the configuration principle of the first and second equipment of the transformer substation.

Description

technical field [0001] The invention relates to an intelligent substation model design method, which belongs to the technical field of electric power system automatic control. Background technique [0002] In the existing smart substation project, the design method is basically the same as that of the original conventional substation. The IED manufacturer provides the device schematic diagram and screen diagram, and the design institute is responsible for drawing the primary and secondary system wiring diagrams according to the project planning. and network wiring diagrams and other engineering drawings, and then the system manufacturer generates a system model file through secondary input, and completes the model configuration. The process is as follows figure 1 shown. [0003] The disadvantages of this design approach are: [0004] 1. Bring duplication of labor and possible errors of artificially inputting information against drawings. In the process of handing over th...

AI Technical Summary

Problems solved by technology

In the process of handing over the engineering drawings provided by the design institute to the integrator to generate the model files, it is inevitable that multiple times of manual input of information is required, which greatly increases the possibility of errors

[0005] 2. The progress depends heavily on the equipment manufacturer

Since the drawings provided by the design institute do not directly involve model files, the manufacturer must assist in the design of the data information flow and model configuration in the station during the design, construction, commissioning, and maintenance processes. Basically, the manufacturer controls the joint debugging work progress and project progress , bringing a large number of vendor coordination problems and work

[0006] 3. The expected convenience was not obtained when the substation was rebuilt and expanded

Since the system integration is completed by the equipment manufacturer, and the device configuration tools and system configuration tools lack versatility, if the manufacturer is replaced during reconstruction and expansion, the original configuration inheritance is very limited, which greatly limits the flexibility of engineering reconstruction and expansion
