Abstract

The invention discloses an IEC61850-based CAD electric power graphic generation analysis method, which comprises the steps of: defining more than one connecting terminal graphic block for equipment primitives and position regions calculated via supporting positions of connecting terminal graphic blocks according to an IEC61850 standard, and defining the actual information represented by the equipment primitives in the graphic blocks subordinative to the equipment primitives as an attribute; calculating the number of connecting terminals on the two ends of virtual terminals in a selected SCD file, calculating the spatial dimensions of the equipment primitives, arranging the primitives of the virtual terminals, and drawing connecting lines of the arranged primitives of the virtual terminals; acquiring terminals included by the primitives and absolute positions of the terminals according to the primitives of the virtual terminals, acquiring the connecting relation of the terminals, and outputting an SSD file according to the IEC61850 standard. The invention has the advantages of avoiding an error due to manual primitive connection, improving the making speed and level of intelligent transformer substation SCD and enhancing the design efficiency of a CAD electric power graphic.

Description

technical field [0001] The invention relates to the technical field of power system design, in particular to a method for generating and analyzing CAD power graphics based on IEC61850. Background technique [0002] CAD drawing is widely used in electric power design, and is often used in the design of wiring diagrams and terminal diagrams of various systems. There are also some supporting plug-ins to speed up drawing design. In these system designs, some of them have produced a large number of different types of drawings based on CAD. Blocks can be used to quickly create drawings, but they cannot be analyzed; some graphics elements can be customized based on other platforms for quick analysis and drawing, but CAD drawings cannot be directly output. AutoCAD has introduced ActiveX Automation technology since R14, which allows languages ​​and applications in various object-oriented programming environments such as VC, VB, and Java to communicate directly with AutoCAD through Ac...
