This paper overviews a traction system for Tokaido Shinkansen trains and presents novel silicon carbide (SiC)-applied of the new generation train, “N700S”, which began commercial service in summer 2020. To achieve compactness weight reduction, N700S's aimed to take advantage merits SiC devices, have lower power loss, higher frequency, current than Si not only conversion but also entire system. ...

Train network control management system (TCMS) is an important part of the High-speed rail train. Because TCMS's complex and redundant structure, long-term operation environment, etc., breakdowns inevitably in long-time running. Based on historical fault data TCMS accumulated during their online service, working principles, failure modes, effects analysis are researched dynamic tree (DFT) model...

A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed. And the influence of slab length on dynamic characteristics of the system under different track conditions and train speeds are theoretically...

The impact of converter control strategies on the drive train of wind turbines during voltage dips is investigated in this paper using a full electromechanical model. Aerodynamics and tower vibration are taken into consideration by means of a simulation program, named FAST. Detailed gearbox and electrical subsystems are represented in MATLAB. The dynamic response of electromagnetic torque and i...

Next generation wireless/mobile networks will be IP based cellular networks integrating the internet with cellular networks. In this paper, we propose a new architecture for a high speed transport system and a mobile management protocol for mobile internet users in a transport system. Existing mobility management protocols (MIPv6, HMIPv6) do not consider real world fast moving wireless hosts (e...
