Within this paper, a first approach for the selection of the appropriate machine will be presented. The constant need of electrical drive trains and therefore electrical machines requires the selection of the right electrical machine regarding the application requirements. Within this work, the different machine types are briefly opposed to each other regarding their disadvantages and advantages. Then, existent machines of those types are compared based on power density (volume, weight) and efficiency. Finally, reliability is an important factor for the selection procedure, thus it will be explained how reliability estimation can be used for multi-phases permanent magnet synchronous machines, even though there are not enough data available.

Early detection of faults in power lines allows improve the service quality and therefore a reduction in high operating costs that a failure of this type implies. This paper describes a method used to determine the type of failure occurs in a three-phase over time, using tools as Hilbert transform and fuzzy classifier for successful detection is done. The algorithm developed uses each of the power lines phases which are analyzed in its angle of coverage and its variation in time, after this analysis the results classified by a classifier Fuzzy c-means. This classifier makes groups of fault data and no-fault data. The results show a high performance in classified values near to zero as correct.

Authors have developed a train running energy simulator with some functions of speed profile generators and an equivalent feeding circuit model for the purpose of the energy estimation of commercial train running. Energy consumption depends on feeding voltage, which varies according to the running position of the train and the condition of other running trains. Therefore, the developed simulator has an equivalent feeding circuit model for commercial train running. This paper verifies the developed simulator using recorded running data of commercial trains.

A simulator with high precision for calculating energy consumption in train operation has been developed by authors. In order to improve the accuracy of the simulator, it is important to input running resistance with high precision under various conditions to the simulator as parameters. Therefore, this paper proposes a method of calculating running resistance under various conditions without the running tests by using monitoring data on service trains, the track and structure database and the weather database. In addition, this paper reports the case in which the precision of the simulation results is improved by using the running resistance formula by this method.

An increasing number of ships are being integrated with electric propulsion systems and a significant proportion of these require variable frequency drives in the multi-megawatt range. At such large power, medium voltage AC (MVAC) drive offers numerous advantages over low voltage AC (LVAC) solution. This paper examines the state-of-the art MV drives and their development trends for marine applications. Further, a review is carried out on multilevel converter (MLC) topologies suitable for high power ship propulsion drives. A variety of topologies are evaluated for marine applications based their specific requirements. From the review, it is concluded that hybrid solution seems the most attractive option for the specified application.

High-speed traction motor is the central component of the power traction system in high speed CRH train, and also the key power output device. Its reliability determines the power traction system security, and its thermal safety issue is one of the key researches, especially the working temperature rise of the stator windings and slot insulation. Based on the forced air cooling system and the multiple operating states, the fluid flowing states and heat transfer in traction motor is investigated. A 2D temperature analysis method is proposed, in which the highest temperature of insulation section determine based on the 3D fluid calculation is taken as the analysis model. This could ensure the accuracy of the insulated thermal safety assessment, and save a lot of computing time. It provides a reference method for the design and analyses on such motor.

In future all-electrical ships with Medium Voltage DC distribution, the power system stability can be jeopardized by the presence of constant power loads, due to the negative impedance characteristic of their tightly regulated converters. In order to solve this problem we apply backstepping as a nonlinear control technique to the converter interfacing the generation side and which supplies the bus. In this work we demonstrate two versions of backstepping, which are compared to a centralized linearizing state feedback controller taken from literature.

Paper presents new topology of an AC boost rectifier that is used to draw the sinusoidal current from single phase overhead traction supply system through single phase transformer delivering 50 or 16.7Hz voltage depending on traction technology. The AC boost rectifier means that it operates as power factor correction. The topology of the boost rectifier system is modification of Warsaw and Vienna rectifier but it is adapted to two phase system. The boost rectifier delivers two DC stabilized voltages that are dedicated to supply 3 level DC/AC converter. The paper presents theory of the boost rectifier supported by state equations system, equivalent diagrams and simulation of an example 80 kW auxiliary power system used in locomotives.
