“…Oversizing might unnecessarily increase the weight and volume of OESSs, while undersizing could be critical for energy efficiency and time-schedule compliance [4]. For the broader use of energy storage systems and reductions in energy consumption and its associated local environmental impacts, the following challenges must be addressed by academic and industrial research: increasing the energy and power density, reliability, cyclability, and cost competitiveness of chemical and electrochemical energy storage devices [5,6]; integrate onboard and wayside storage systems and develop efficient control strategies for energy sources [7][8][9][10][11][12]; increase the power density of electronic converters and introduce new concepts and materials for traction motors [13][14][15].…”

Despite low energy and fuel consumption levels in the rail sector, further improvements are being pursued by manufacturers and operators. Their primary efforts aim to reduce traction energy demand, replace diesel, and limit the impact of electrified overhead infrastructures. From a system-level perspective, the integration of alternative energy sources on board rail vehicles has become a popular solution among rolling stock manufacturers. Surveys are made of many recent realizations of multimodal rail vehicles with onboard electrochemical batteries, supercapacitors, and hydrogen fuel cell systems. The ratings, technical features, and operating data of onboard sources are gathered for each application, and a comparison among different technologies is presented. Traction system architectures and energy-control strategies of actual multimodal units are explored and compared with literature research. Moreover, the maturity and potential of recent technologies and alternative topologies of power converters for multimodal traction systems are discussed. Ultimately, onboard storage systems are compared with other solutions for energy-saving and catenary-free operation, with particular focus on their current techno-economic attractiveness as an alternative to diesel propulsion.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…The system analysis presented by Schneider [19,20] describes the effects of a wheelset overloading caused by the combined load from torsion oscillations and acting lateral forces. The importance of the research of the harmonic components was also pointed out by Takahashi et al [21], who focused specifically on the efficiency of traction motors for railway vehicles, or in the work of Lu et al [22], which proves, that pulsating motor torque has significant influence on the wheel-rail contact forces and longitudinal and vertical vibrations within the vehicle bogie.…”

This paper deals with the phenomenon of torsion oscillations in railway vehicle drive systems. The main goal is to reduce the risk of presence of torsional oscillations in wheelset drive, eventually to propose systems to effectively identify and eliminate torsional oscillations of wheelsets. Therefore, a simulation wheelset drive model including a detailed model of the asynchronous traction motor control was built. The results of computer simulations show that the torsional oscillations can be effectively eliminated by avoiding the resonance states between the excitation frequencies given by pulse width modulation of the inverter and the eigenfrequencies of the mechanical part of the drive. Furthermore, it was found that the presence of torsional oscillations of the wheels can be detected based on the traction motor current ripple. The wheelset drive model was subsequently implemented in a simulation model of a four-axle locomotive. A new algorithm of an anti-slip protection system that utilizes motor currents was implemented in the model. Simulations show that such an anti-slip protection system can prevent the occurrence of undesired large amplitude of wheelset torsional oscillations. The models and simulation results are presented in detail in the paper.

“…Os autores relataram a aplicação bem sucedida do PMSM em ferrovias de alta velocidade pela China no ano de 2014, sendo o quarto país a dominar a tecnologia em questão após Japão, Alemanha e França Zhang et al (2019). em seu trabalho propuseram um método "sensorless", sem sensores, para controle do PMSM em transporte ferroviário com a utilização de modulação síncrona segmentada, com base na injeção de sinais arbitrários para a estimação da posição rotórica Takahashi et al (2020),. em seguida, conceberam um PMSM de alta eficiência para aplicação ferroviária com base em estrutura de polos magnéticos assimétricos, para redução de pulsação e ripple de torque, sem comprometimento da componente CC do torque de saída sob o controle baseado em máximo torque por ampere (MTPA), alcançando eficiência nominal de 98% para a máquina e redução de perdas de até 15% comparativamente ao motor assíncrono de tração convencional, perante testes de operação comercial Luo et al (2020).…”

Os desenvolvimentos científicos e tecnológicos ocorridos nos últimos anos impreterivelmente guardam um compromisso justificado com a elevação dos índices de eficiência energética, em favorecimento da preservação ambiental e de recursos naturais em escala global. Ainda que formas cada vez menos poluentes para o uso da energia cresçam exponencialmente em utilização, os desafios posteriores se situarão adicionalmente na pesquisa por otimização das tecnologias existentes. Neste contexto, este trabalho realiza no domínio da aplicação em transporte urbano ferroviário um estudo comparativo para a utilização do motor síncrono de ímãs permanentes como acionamento de tração elétrica, perante outros modelos já estabelecidos e consolidados no mercado, principalmente em termos de eficiência energética. Este estudo se fundamenta inicialmente na revisão teórica baseada na literatura para sistematização de características de engenharia intrínsecas do acionamento em questão, para que em sequência com a conceituação das propriedades de dinâmica do movimento se obtenha por meio de simulações os dados necessários para a elaboração da comparação por meio da investigação de aplicações e estudo de caso.Palavras-chave: Máquinas. Tração Elétrica. Ferrovias.
