Design method of intelligent substation model based on cad graphics and model integration

Abstract

The invention discloses a design method for an intelligent transformer station model based on CAD (Computer-Aided Design) graph and model integration. According to the method, the design of a secondary loop and the generation of a model file of the intelligent transformer station are synchronously completed; a data object corresponds to the back of each entity, and the model can be operated by a graph, therefore, the consistency of the design of the secondary loop and the model file is ensured, and the problem that the traditional intelligent transformer station is not deep enough is solved; and synchronously the design of the transformer station model can be finished by designers not familiar with 61850 design details, the role and the function of a design organization are strengthened in the establishing of the intelligent transformer station, and the visibility in operation and maintenance of the transformer station is increased; furthermore, the method is combined with the habits of traditional designers and is used for performing graphical loop design based on an AutoCAD platform so that the operation of the designers is convenient; an IEC61970CIM model is used in a primary system to describe the model, therefore, the data supporting other applications can be exported, and the openness of the method is increased.

Description

technical field [0001] The invention relates to an intelligent substation model design method based on the integration of CAD graphics and models. Background technique [0002] At present, the design of smart substation mainly focuses on the modeling tool level of smart substation, and only takes the input and output of IEC61850 SCD, ICD, CID and other modeling results as the main task. These documents are mainly used by engineering personnel of IED manufacturers, neither considering the comprehensive intelligent substation engineering design results nor considering the combination of design drawings and IEC61850-SCL. Since the design unit has no suitable or available design means, the engineering design is limited to the degree of completing the hard wiring design, and cannot provide the function configuration, communication configuration and related design materials of the intelligent device required in the project construction stage. The engineering construction phase of...

Problems solved by technology

[0004] The main problem in the patent with the publication number CN101989312A: Since the attribute of the primitive block is two-dimensional, and the IEC61850 model has multi-dimensional characteristics, if a two-dimensional characteristic block is used to describe the multi-dimensional IEC61850 model, the IEC61850 model must be divided first It is a number of primitive blocks
