Abstract
The design of an electrical substation is a complex task, which involves the execution of a series of the same type of calculations, which take considerable time. It is rational to use specialized CAD software to perform such operations. Currently, the existing CAD systems of electric power facilities are either designed for calculating electric networks, or they allow only one or several stages of the substation project to be performed. This paper is devoted to the development of a CAD algorithm for electrical substations that carries out computer-aided design in a complex, from the terms of reference to the formation of a set of design documentation. The article describes the algorithm for the automated selection and verification of high voltage cables implemented in this CAD system. The algorithm takes into account the requirements of the rules for the operation of electrical utilities and the current guidelines for the operation of cables in normal, heavy and emergency conditions.
