Co-phase Traction Power Supply with Railway Hybrid Power Quality Conditioner by Keng-Weng Lao

English | PDF,EPUB | 2018 (2019 Edition) | 242 Pages | ISBN : 9811304378 | 23.11 MB

This book offers a brief review of and investigations into the power quality problem in the new technology of co-phase high-speed traction power supplies, which benefits for higher locomotive speed. In addition, it presents detailed design procedures and discusses the chief concerns in connection with a newly proposed solution: compensation in co-phase traction power using a co-phase railway hybrid power quality conditioner (Railway HPQC). Further, it provides essential information on the modeling of power quality in co-phase, high-speed traction power supplies, and on power quality compensation algorithm derivations. Lastly, it delineates the design of railway HPQC and analyzes the effect of different parameters on its performance to accommodate different priorities. All design is supported by simulations and the results of experimental verification.

Transient Effects in Simulations of Hybrid Electric Drivetrains By Florian Winke

English | PDF | 2018 (2019 Edition) | 140 Pages | ISBN : 365822553X | 1.41 MB

This work presents an investigation of the influence of different modeling approaches on the quality of fuel economy simulations of hybrid electric powertrains. The main focus is on the challenge to accurately include transient effects and reduce the computation time of complex models. Methods for the composition of entire powertrain models are analyzed as well as the modeling of the individual components internal combustion engine and battery. The results shall help with the selection of suitable models for specific simulation tasks and provide a deeper understanding of the dynamic processes within simulations of hybrid electric vehicles.

Design and Electromagnetic Feature Analysis of AC Rotating Machines by Ahmed Masmoudi

English | PDF,EPUB | 2018 (2019 Edition) | 100 Pages | ISBN : 9811309191 | 5.55 MB

This book provides the basis of the design of rotating AC machines. The first chapter puts the emphasis on the air gap magnetomotive force (MMF) of Rotating AC machines and the second chapter deals with the formulation of the rotating fields that could be generated considering different technique. The third chapter of this book focuses on the arrangement of the armature winding of fractional-slot concentrated winding permanent magnet synchronous machines, which is achieved considering the star of slots approach.
Each topic is explained by case studies that show how to implement the theory into real-world design of DC machines.

A Survey of Fractal Dimensions of Networks by Eric Rosenberg

English | PDF,EPUB | 2018 | 87 Pages | ISBN : 3319900463 | 8.99 MB

Many different fractal dimensions have been proposed for networks. In A Survey of Fractal Dimensions of Networks the theory and computation of the most important of these dimensions are reviewed, including the box counting dimension, the correlation dimension, the mass dimension, the transfinite fractal dimension, the information dimension, the generalized dimensions (which provide a way to describe multifractals), and the sandbox method (for approximating the generalized dimensions). The book describes the use of diameter-based and radius-based boxes, and presents several heuristic methods for box counting, including greedy coloring, random sequential node burning, and a method for computing a lower bound. We also discuss very recent results on resolving ambiguity in the calculation of the information dimension and the generalized dimensions, and on the non-monotonicity of the generalized dimensions.
Anyone interested in the theory and application of networks will want to read this Brief. This includes anyone studying, e.g., social networks, telecommunications networks, transportation networks, ecological networks, food chain networks, network models of the brain, or financial networks.
