Automation of calculations in the designing of power supply systems of residential buildings

The article reviews the existing CAD systems for power supply for residential buildings. The technique for selecting conductor cross sections is presented. On the basis of the methodology, an algorithm was developed and its software implementation in C++ and databases in Microsoft Office Access was implemented. The program selects the required type of cable, its section, checks the selected cross section by loss of voltage, and also selects protective equipment. The main advantages of the developed program: simple interface; the program is fully automated and free of charge; compatible with various OS. Using Microsoft Access databases allows the user to make changes.
