Software development scheme based on AutoCAD for graphical model design of smart substation
HU Huawei · Dianli zidonghua shebei · 2012
It is suggested that the design of smart substation model and internal data flow should be taken by the design institute to ensure the unity and uniqueness of substation data sources and a software development scheme of graphical model design is proposed to simplify the engineering of designer.The ActiveX Automation technique of AutoCAD is adopted in the secondary development.The graphics editor and model editor module of its software modules associate the IEC61850 model documents with the CAD graphics.Extended attributes are added in CAD blocks for modeling and the model information exchange between the model text and the graphics file is via the XML database to enhance the speed of model access and search.The final model design and drawings are completed by engineering plus attribute value setting.
