Algorithm for computer-aided design of single-line diagrams of 35-220 kV switchgear with one working busbar system using "ORU CAD"

Designing distribution systems for substations and power plants is a complex process that requires qualification, attention, knowledge of regulatory and technical documentation and takes a lot of time to perform the same type of work. In addition, an integral part of the preparation and delivery of any project is the development of project documentation, including an explanatory note to the project, specifications and, of course, drawings with single-line diagrams, plans, layout schemes, etc. The paper proposes an algorithm for automated design of single-line circuits of open switchgear 35-220 kV with bus bars, implemented in the original software "ORU CAD". The study was carried out with the financial support of the Russian Foundation for Basic Research in the framework of the research project No. 18-37-00115. (paper)
