“…Battery is modelled with an ideal voltage source E in series with a resistor R L =0.5Ω, which represents battery's internal resistance. Asymmetrical six-phase induction machine parameters, used in the simulation, are the following: R s =12.5 Ω, R r = 6Ω, L γs =5.5mH, L γr = 11mH, L m = 590mH, three pole pairs, J = 0.1kgm 2 . The charging mode is considered first.…”

AbstractThe paper considers a novel fast charging topology for electric vehicles (EVs). Instead of being made as a separate unit, the proposed on-board charger utilizes power electronics components that already exist inside the vehicle, namely an asymmetrical six-phase propulsion motor and a six-phase inverter. The charger can operate at unity power factor, and is capable of vehicle-to-grid (V2G) operation as well. Additional degrees of freedom of the six-phase machine are employed in order to transfer a part of excitation from the torque producing to non-torque/flux producing plane of the machine. Consequently, electromagnetic torque is not produced in the machine during the charging/V2G process, so that the rotor does not have to be mechanically locked. A theoretical analysis of the operating principles is reported, and simulation results are given for both charging and V2G mode of operation.

Due to the serious imbalance of the secondary load of traction transformer, the negative-sequence current in the three-phase side is large, which inhibited the development of the technology of taking power from traction network. The negative-sequence current characters of power transformer for railways of five connection types by symmetrical component method, including D,y11, D,d0, Y,y0, Y,d11 and Reverse-Scott is discussed in this paper. Moreover, an improved Reverse-Scott connection type is proposed to reduce the unbalanced degree.

“…Massive public transport systems that operate connected to an electric power grid will continue to be the core of transportation in large cities, as various research papers [1]- [4] point. Electricity supply networks will be increasingly clean because of the incorporation of renewable energies and more intelligent allowing to optimize vehicle-vehicle and vehiclenetwork energy exchanges.…”

The paper presents a method to determine the proper infrastructure to supply electric energy for multimodal public transportation networks. The method integrates computational simulation tools in order to precisely calculate the power demand of each public transit system, and then, by accumulating the individual consumptions, obtain the global power system demand. The method is applied to the multimodal network operated by Metro de Medellin, which at the moment is experiencing an expansion.
