Formalization of program simulation power supply system of consumers not traction railway to investigate the reliability parameters

The article describes a software tool simulation of power supply system (IM SES) is designed to select the most cost-effective and reliable option and the basic parameters of the railway enterprise power supply system. The initial data are used data on the basic parameters of the external power supply, the list of transformer substations (TS) with the low-voltage loads or a list of workshops and housings with their loads and location.
