Shaft generator (SG) systems have been exploited for long due to several appealing advantages they present. This type of generators is installed at the shaft of the main propulsion diesel engine while they are capable of operating as propulsion engine boosting devices if suitable power electronics are used. In this paper an effort is made to provide a comprehensive analysis of shaft generator role in ship power system efficiency improvement in relation with ship operation optimization point of view. Special reference is made to the interdependence of SG with power management system as they alter the operation point of both propulsion engine and the electrical generators affecting the optimal operating point.

Operators in railway Industry have to cope with an heterogenic network, with different gauges and supply systems. For being able to run on these tracks, Operators require different types of trains, each one adapted to the specific characteristics of the line. This fact prevents scale-economies to be applied to the sector, managing in a less efficient way peak and valley demands as well as maintenance tasks. Talgo Hybrid Train is the perfect and long-time demanded solution for this problem. It can run on both electrified and non-electrified lines, and within electrified lines both AC and DC supply is supported. Furthermore propulsion bogies have been designed to allow dynamic gauge change. Talgo Hybrid Train is an all-track train that provides maximum interoperability, eliminating railway barriers since one train is enough to operate on almost any line.

Regarding battery systems for electric vehicles a lot of steps have to be taken into account during the development process - from system layout to the integration in the vehicle. In doing so, the overall design of a battery pack can be divided in mechanical, thermal and electrical issues. This work aims to give an insight to crucial points in these areas such as the layout of the battery management system and its interference with the rest of the vehicle. The stated design recommendations shall be provided among others with results from research projects supported by the German Federal Ministry of Education and Research and the Federal Ministry of Economics and Technology.

An observer-based indirect field oriented control scheme is proposed for the speed and traction control of electric vehicles powered by induction motors with uncertain constant load torque and stator and rotor resistances. The novel control architecture transforms the vehicle speed reference into a suitable motor speed reference and then guarantees the motor speed regulation to the corresponding reference on the basis of the motor speed regulation error. The motor speed measurement, which is typically available in electric vehicles, is used not only for traction control but for regulation purposes as well. The closed loop on-line identification of the three critical uncertain parameters allows for on-line estimating and imposing the motor flux modulus reference value which minimizes power losses and improves power efficiency.

Pantograph-catenary systems with their dynamic behavior resulted in being crucial components of new high-speed train systems. Structural modifications on pre-existing lines are very difficult and expensive, and they cause practicability issues. Thus, in order to alleviate the problems associated with the introduction of high speed trains (contact, abrasion, excessive oscillations of the catenary, etc.), active control of the pantograph can be introduced. In collaboration, ESIEE-Amiens and the University of Florence have been working on the evaluation and modeling of the catenary-pantograph contact, including intensive work regarding the definition and tuning of several control strategies for an active pantograph. In particular, ESIEE-Amiens has provided its OPAL-RT real time architecture with an implemented catenary model [1] and the University of Florence has provided its expertise on active control strategies of pantographs [2].

The main fields of research in this article cover the execution of some diagnose, control, data base, analyse and management systems applied to the locomotives. These systems monitor the following: the vehicle's position in the land and the actual speed; the technical parameters for the electric traction motors and the auxiliary services, main command circuits, the voltage in the live wire; the storage of data concerning the power consumption and the status of the “dead-man” safety system; the storage of data concerning the activity of the on-board personnel and its audio and video communication with the traffic control. The research cover as well the transmission, reception and complete analyse of all the parameters discussed above, at the traffic control level, by the human operator which supervises the running vehicles.

An electronic system is compatible with its electromagnetic environment if it satisfies the following two criteria: it does not emit (unintentional) electromagnetic energy above a certain minimum level, and it is not susceptible to malfunction if unintentional electromagnetic energy below a certain level is incident on it. This paper presents a study on the effect that electromagnetic interference has on the speed sensor an aircraft starter generator. An experimental setup was created to generate the radiated emissions, and results were plotted on the oscilloscope. Results obtained by measurement were also compared to the theoretical results.

The paper focuses on the hardware and software implementation of a novel sensorless rotor temperature estimation technique for Permanent Magnet Synchronous Machines (PMSMs). The method requires an intermittent injection of a voltage pulse in the d-axis of the motor while the q-current is kept zero. The slope of the resulted d-current response reflects a given saturation level of the machine stator steel core which is distinctive for a given magnet temperature. Since this is a strongly non-linear relationship, a look-up-table (LUT) for the motor is required. In order to capture correctly the current derivative, a synchronous oversampling of the d-current along the voltage pulse duration is required. The paper demonstrates a suitable hardware setup and software integration of the method into a common field oriented space vector control.

The locomotive type HD300 is a developed diesel hybrid shunting locomotive. The series hybrid system of the type HD300 is composed of a diesel engine and a lithium-ion battery. As a result of a hauling test, the type HD300 achieves environmental load reduction compared with a conventional diesel shunting locomotive. This paper shows an environmental evaluation while revealing factors of reduction effects.
