The goal is to develop methods and tools for sustainable management of high-speed movement of trains and power supply conditions for increasing safety and improving energy conservation based on an integrated approach to the development and interaction of subsystems train control, power supply, digital networks operational and technological communication, technical control and diagnostics subsystems, providing them with technical and technological compatibility and functional safety, reducing energy losses in reverse traction network and reduce the number of failures in the system ALSN due to the impact of reverse traction current.The novelty: first proposed mathematical model of power circuits ERS with ATP considering processes in a power transformer, 4q-S, inverters and windings ATP using real parameters of power switches, analytical solution of the model equations and its implementation in the package OrCAD PSpice; first developed a scientific substantiation of the proposed method of selective compensation of interference in track circuits, the essence of which is the reduction in track circuits only those noise frequencies that are in the bands work receivers track circuits; an improved mathematical model of the traction network with an active shield conductor influence on track circuits; an improved method for measuring the electromagnetic interference from the ERS during their tests. The results of the thesis are intended for use on the railways. Product Description popup.authors Акулов А. С. Безнаритний А. М. Буряк С. Ю. Василішин Д. О. Гололобова О. О. Грецько О. С. Дорохін Б.
