A modern tool for research and rapid prototyping of new developments are various methods of digital system modeling. When creating or upgrading any electric transport systems and electric rolling stock, the correct choice of all elements of the traction power supply system and electric rolling stock is of great importance. To solve this problem, it is necessary to take into account the movement of a set of moving loads in the form of electric transport in power supply systems of various levels and, at the same time, to study not only the mechanical processes of electric transport movement, but also the electromagnetic processes of interaction of electric transport with the traction power supply system and the electric power system, as well as their mutual interaction. electromagnetic influence on each other. The construction of a software and hardware complex for real-time simulation of the joint operation of electric power systems, traction power supply systems and electric trains corresponds to the modern moment. The implementation of such a system is possible using modern high-performance computing systems or stationary supercomputers with integrated hardware that increase the speed of calculating stiff systems of differential equations that describe large electro-magnetic-mechanical systems. Such computing software and hardware systems are quite expensive. The article describes the composition of such a complex and the feasibility study for its development and implementation.
