Developing an Algorithm Used to Automatically Arrange Filling Diagrams of Outdoor Switchgears with Bridge Connection

Drawing up filling diagrams is an important stage in designing substations. This paper presents an algorithm used to automatically arrange filling diagrams of outdoor switchgears with bridge and block connections. Particular attention is paid to studying all possible types of bridge and block connections at 35 to 220 kV, the design of the algorithm used to draw up filling diagrams, as well as the debugging of designed algorithms. The novelty of these algorithms lies in the fact that each of them takes into consideration all possible types of outdoor switchgear arrangements. These include possible substation extension in the future, the addition of current and voltage transformers, and the arrangement of power line cells. The designed algorithms have been executed in the Outdoor Switchgear CAD software.
