“…As has been noted in [1][2][3][4], the influence on the catenary system can be reduced by equipping ERS with an energy storage device (ESD). This device will allow accumulating braking energy and using it in subsequent accelerations.…”

In addition to obtaining necessary dynamic characteristics and broadly using modern solid-state traction converters, intensified electric rolling stock (ERS) traffic flow and increased travel speeds have a significant influence on the catenary system and cause voltage dips and surges. This article considers the possibility of stabilizing the voltage of a catenary system section by means of an automatic voltage stabilizer that uses the energy accumulated in an electricity storage device. This stabilizer is designed as a reversible solidstate converter used to charge and discharge the energy storage device. The proposed formulas are used to make up a mathematical model the main strength of which is the usage of real data collected from urban ERS traffic flows. The test results show that a voltage stabilizer using the energy of the storage device can reduce the influence of ERS on the catenary system voltage.

“…Similarly to the installation of an ESD on the rolling stock [1][2][3][4], the installation of ASCSs in heavytraffic areas will weaken the influence of the ERS on the catenary system, but with a lower number of ESDs and without increasing the ERS weight.…”

“…In contrast to the well-known Hyper Loop transport system [2][3][4][5][6][7][8][9][10][11][12], the design under consideration involves a departure from the spindle shape of the crew for reasons of stability concerning rotational perturbations (relative to the longitudinal axis of the crew).…”

Movement of passenger crews in a rarefied air tube at speeds over 600 km/h involves the effect of magnetic levitation and a traction linear superconducting synchronous motor with a stator winding distributed along the length of the tube and a superconducting excitation system on the crew. Conditions of magnetic levitation stipulate that the position of the crew in the tube is characterized by six degrees of freedom, so a traction linear superconducting synchronous motor must be considered as a multi-stage dynamic system. However, in the “normal” operational mode, the problem is reduced to consideration of the system with one degree of freedom with the coordinate that determines the position of an inductor with superconducting winding and without ferromagnetic cores relative to the running magnetic field of the stator winding. The specifics of magnetic levitation of the moving crew, which consists in the possibility of its spatial displacement, cause the appearance of geometric parameters characterizing progressive and rotational perturbations of the coordinates of the center of inertia of the crew in expressions for mutual inductances between the superconducting excitation system, electromagnetic shield, and the stator phase windings.
