The characteristic impedance and propagation constant define the behavior of signal propagation over the transmission lines. The digital model for railway traction lines which includes railway tracks is developed, using curve fitting technique in MATLAB. The sensitivity of this model has been computed with respect to frequency.
The digital sensitivity values are compared with the values of analog sensitivity. The developed model is useful for digital protection, integrated operation, control and planning of the system. Due to the increasing importance of reliability and availability of electric traction drives in Railway applications, early detection of faults has become an important key for Railway traction drive manufacturers.
Sensor faults are important sources of failures. Among the different fault diagnosis approaches, in this article an integral diagnosis strategy for sensors in traction drives is presented. Such strategy is composed of an observer-based approach for direct current DC -link voltage and catenary current sensors, a frequency analysis approach for motor current phase sensors and a hardware redundancy solution for speed sensors.
None of them requires any hardware change requirement in the actual traction drive. All the fault detection and isolation approaches have been validated in a Hardware-in-the-loop platform comprising a Real Time Simulator and a commercial Traction Control Unit for a tram. In comparison to safety-critical systems in Aerospace applications, Railway applications do not need instantaneous detection, and the diagnosis is validated in a short time period for reliable decision. Combining the different approaches and existing hardware redundancy, an integral fault diagnosis solution is provided, to detect and isolate faults in all the sensors installed in the traction drive.
Advantages of low frequencies in converter-supplied railway traction power systems. As soon as a railway will be supplied from the public 50 Hz grid by means of static converters and no longer by direct transformers, you are free to choose its frequency.
Control algorithms for single inverter dual induction motor system applied to railway traction ; Commande algorithmique d'un systeme mono-onduleur bimachine asynchrone destine a la traction ferroviaire.
The goal of this work concerns the modelling and the behaviour characterisation of a single inverter dual induction motor system applied to a railway traction bogie BB in order to concept its control.
First part of this job is dedicated to the detailed description of overall system. The influence analysis of the internal perturbations motor parameters variation and, external perturbations pantograph detachment, adherence loss, stick-slip of the system have made considering the field oriented control applied to each motor of the bogie classical traction structure. It is composed by a single pulse-width modulated two level voltage source inverter. It supplies two parallel connected induction motors, which generate the transmitted traction force to the bogie wheels.
The locomotive case represents the common load for the two motors. Several co-operative control strategies CS are studied. In addition, an appropriated electric modes observer structure for these different controls has studied. This special approach is equivalent to quasi-experimentation, because the mechanical and the electrical system components have modelled using MAST language and, the sample control has created by a C code programme in the SABER environment.
Third part is dedicated to the mechanical sensor suppression and, its adaptation in the cooperative control strategies.
The partial speed reconstruction methods are: the fundamental frequency relation, the mechanical Kalman filter, the variable structure observer and the MRAS. Finally, the hardware system configuration of the experimental realisation is described.

This paper deals with the automatic design of static converters and electrical machines. Facing the multitude of such devices converters-machines , the choice of the appropriate converter or machine is a delicate problem.
A high level of expertise is required to determine the best structure for the considered application. This choice could be rapidly made if one had a system which incorporates a great knowledge of converters, machines and control methods. Firstly, the authors review the realized studies, then they propose this methodology for a concrete case in order to optimize an inverter-motor of a railway traction chain.
Constraints are described in terms of input and output performances losses, current,.. These data are analyzed by using design rules and methods which allow the decrease of the manufacture cost of the inverter-motor. The article proposes several tracks which involve organization, methodology, confirmation and implementation of a tool supporting a method. This process of implementation is the most efficient to fit into a constant process of improvement which is supported by the return on experience and by the evolution of the state of the art.
Operation analysis of AC traction motors in terms of electromagnetic torque capability on sustainable railway vehicles. Directory of Open Access Journals Sweden. Full Text Available Sustainable operation of electric railway systems represents a significant purpose nowadays in the development of high power and high speed locomotives and trains.
At present, high speed electric vehicles mostly work with three-phase induction motors or three-phase synchronous motors as traction motors. The two electric machine types have different efficiencies at different operation points, and experience differences with respect to safety, speed and power, energy use and exergy efficiency.
An important issue that correlates these aspects is the electromagnetic torque developed by an electric traction motor. The results of this work may help in enhancing the main criteria for optimising the safe and sustainable operation of electric railway traction systems.
Sustainable operation of electric railway systems represents a significant purpose nowadays in the development of high power and high speed locomotives and trains.
Full Text Available Pulse width modulation PWM technology is widely used in traction converters for high-speed railways. The harmonic distribution caused by PWM is quite extensive, and increases the possibility of grid—train coupling resonance in the traction power supply system TPSS. This paper first analyzes the mechanism of resonance, when the characteristic harmonic frequency of a four-quadrant converter 4QC current that injects into the traction grid matches the resonant frequency of the traction grid, which may result in resonance in the system.
To suppress resonance, this paper adopts specific harmonic elimination—pulse width modulation SHE-PWM technology combined with a transient direct current control strategy to eliminate the harmonics in the resonant frequency, which may suppress the grid—train coupling resonance.
Due to the fact that the SHE-PWM process with multiple switching angles contains complex transcendental equations, the initial value is difficult to provide, and is difficult to solve using ordinary iterative algorithms.
In this paper, an active-set secondary optimization method is used to solve the equation. The algorithm has the benefits of low dependence on initial values, fast convergence and high solution accuracy. Finally, the feasibility of the resonant suppression algorithm is verified by means of Matlab simulation. Open coil traction system. Sliding mechanics have become a popular method for space closure, with the development of preadjusted edgewise appliances.
Furthermore, various space closing auxiliaries have been developed and extensively evaluated for their clinical efficiency. With the advent of nickel-titanium Ni-Ti springs in orthodontics, load deflection rates have been markedly reduced. To use Ni-Ti springs, clinicians have to depend upon prefabricated closed coil springs. The open coil traction system , or open coil retraction spring, is developed utilizing Ni-Ti open coil springs for orthodontic space closure.
This article describes the fabrication and clinical application of the open coil traction system , which has a number of advantages. It sustains a low load deflection rate with optimum force magnitude, and its design is adjustable for a desired length and force level. It is fail-safe for both activation and deactivation ie, it cannot be overactivated, and the decompression limit of the open coil is controlled by the operator.
The open coil traction system can be offset from the mucosa to help reduce soft tissue impingement. Traction noise is one of the noise sources of powered railway vehicles such as locomotives, electric- and diesel-powered multiple unit trains and high-speed trains. Full Text Available In this paper, a diagnosis plan is proposed to settle the detection and isolation problem of open switch faults in high-speed railway traction system traction inverters.
Five entropy forms are discussed and compared with the traditional fault detection methods, namely, discrete wavelet transform and discrete wavelet packet transform. The traditional fault detection methods cannot efficiently detect the open switch faults in traction inverters because of the low resolution or the sudden change of the current.
Comparison experiments are carried out to select the best entropy form for the traction inverter open switch fault detection. The simulation experiments show that the proposed plan can diagnose single and simultaneous open switch faults correctly and timely. Full Text Available The conditions for the operation of railway systems are closely related to the increase of the commercial demand; as a consequence, the performance of the structural elements of railways changes.
The present paper focuses on a study of the structural behaviour of bolster-beams under commercial operation conditions of railway systems , specifically in the dynamic conditions generated in events of over- traction and over-braking on the vehicle running. The proposed work is constructed based on the following phases: i analysis of the kinematics of the vehicle; ii development of numerical models, a model based on the multibody theory, and a Finite Elements model; iii development of experimental field tests; and iv development of simulations for a detailed analysis of the structural behaviour for a study of the strain distribution in the main bolster-beam.

Despite this, operators are facing pressure to reduce rail energy consumption to meet efficiency targets, whilst still maintaining service quality and managing increased demand. A number of individual measures have been proposed to reduce energy in the rail sector, often showing good results on specific case studies.
It is generally agreed that the attainable savings of a given measure change dependant on the route, vehicle and service characteristics. However, there is little information in the literature specifically regarding which measures are most suitable for given network types, or how they interact.
This paper therefore aims to begin evaluating the available measures in terms of their suitability for different systems.
