This book is a compilation of knowledge about computer models in the three-phase stator reference frame. Chapters explore several aspects of the topic and build upon research previously presented by contributors. The book aims to provide interesting solutions to problems encountered in the design of railway and analysis in railway motors. The modeling approaches proposed by the authors in this book may become an incentive for readers and researchers to develop their ‘lifehacks’ to solve new problems in induction motor design and testing. Key topics presented in the book: - Approximate calculations of induction motor equivalent T-shaped circuit parameters with the use of catalogue data - Simulations of different types of shaft load, including fluid coupling - Receiving static characteristics of an electric machine during simulation by means of dynamic model - Simulation of the electric drive’s specific applications with three-phase induction motors building - Direct start of an induction motor as part of an auxiliary drive of an AC electric locomotive, containing a capacitor phase splitter, starting with different types of shaft loads (fan or compressor). Special attention has been given to the description of the thermal model of an induction motor with a squirrel-cage rotor, which makes it possible to simulate operating modes when powered by an unbalanced voltage, as well as with squirrel cage defects. The thermal model is presented as a detailed superstructure to the model of electromechanical processes of an induction electric machine. Other key features of the book include references for further reading, an appendix for the parameters of the equivalent thermal circuit of an NVA-55 induction motor. The material presented in the book is of interest to railway motor engineers, specialists in electromechanics and electric drives who use SPICE-compatible CAD applications in their work.

Railway is a form of public transport which serves the society, and its aim is to transport passengers and freight safely, rapidly, reliably, accurately and economically. With an implementation of railway great-leap-forward development, the realization of new-generation rail transport system- Railway Intelligent Transportation System (RITS), whose purpose is to ensure security, improve transport efficiency, elevate service quality and achieve the international standards, has become the inevitable development trend. Aiming to provide high security, high efficiency, and high quality service to the rail transport, for the first time the authors put forward the concept of " RITS ", and systematically discussed its connotation and substantive characteristics, structural model, development framework and core technology, developmental pattern etc; they deeply analyze the service framework, logical framework and physical framework of typical subsystem of RITS --- Intelligent Emergency Rescue and Safety System, and execute optimization design. The purpose of optimization design for RITS is to coordinate system target-oriented designs and realizations among various subsystems, making the entire work better, to achieve a system with best overall performance, the construction of RITS system in China. Combining years’ research and practical experience in RITS, we proposed the "The Theory and Method of Design and Optimization for Railway Intelligent Transportation Systems (RITS) ", presenting it in the form of a book to meet the urgent needs of theory and methods of intelligent transport systems for railway transport. We hope that this book can play the role of throwing a brick to allure a gem, and accelerate further expansion research and application of RITS. The authors of the book engaged in research work of RITS and related fields for many years, successively undertaking and completing the key project of National Natural Science Foundation of "Research on Integrated Information System and Key technologies of High-speed Railway Intelligent Transportation", Ministry of Science and Technology research project "Railway Geographic Information System", "Research on Railway Intelligent Transportation System Standard System", "National Railway GIS Application Service Platform" and "Research on Development Strategy of Railway Intelligent Transportation System", Ministry of Railways research project" Railway Geographic Information System Design and Development", "Research and Development on Qinghai-Tibet Railway Emergency Rescue System and Emergency Rescue Command & Management Information System", "Research on the Railway Emergency Preplan Management" and "Research on Railway Intelligent Transportation System (RITS) Framework", China Postdoctoral Science Foundation-funded project" Research on RITS Framework Design and Optimization Method", faulitating the development of application systems, granting achievements in these projects . We sincerely express our gratitude to the National Natural Science Foundation of China, The Ministry of Science and Technology of China, and The Ministry of Railway of China for their financial support. We would also like to thank Dr. Li ping, Dr. Meng yan, Dr. Qinyong, Master Jia Tianli and Master Shao Yikun etc, for their valuable advice, selfless support and assistance for completion of the book. In the process of writing the book, we reviewed a large number of references, to seek clear concepts, using familiar examples to illustrate various theories and methods, which may enable various types of readers to have a clear understanding and knowledge of the optimized design of RITS. With the limitation of the authors’ knowledge level and the depth as well as the breadth of research, there must be some irregularities of views, methods and theories in the book, which the readers may duly criticize. This book combines theories and applications closely, and is convenient for readers’ self-study. The book is also adequate for colleagues engaged in work and research in the rail transportation field, as well as colleges and universities, graduate students and scientific researchers in interrelated fields.

Focusing on reducing emissions and improving fuel economy, automotive manufacturers are developing electric vehicles (EV) to replace fuel and diesel vehicles starting in 2030 onwards. The EVs, with their green power supplies maximize environmental benefits with zero emissions thereby lowering air pollution levels. There is now an increased demand for stable electric storage systems (ESS) that are part of the design of new electric vehicles. This timely reference gives an overview of modern electrical power systems applied in the current generation of electric vehicles which require an ESS, and how these can be utilized for simultaneous power and data communication. The book starts with an introduction to the topic, before giving a summary of the green power trend for the electric vehicle market. The book then delves into the theoretical and analytical framework required to understand adaptive compensation of the magnetic inductive system (ACMIS), based on zero voltage switch (ZVS). The chapters demonstrate how these systems are used for transmitting electric power from a single-end inverter combined with a compensated network of parallel to parallel (P-P) type and an auto-tuning impedance of LC tank. The book also covers the experimental method for a multifunctional contactless power flow of the G2V mode and bidirectional outer communication and inner communication with giant magnetoresistance (GMR) effect for car parking guidance. The experiment shows how to analyze data transferring performance including the current trimming method and how to evaluate data transmission quality according to the relevant parameters. Overall the book serves to familiarize automotive engineers and industry professionals involved in the electric vehicle market with the issues that surround wireless power charging and data transfer systems for electric vehicles, and introduces them to more coherent designs.

This e-book details state-of-the-art drive by wire technology. Readers are made aware about the challenges ahead that need be addressed in order for this technology to gain a foothold in the automotive industry. The eBook presents a systematic analysis of these issues and points out the fundamental reasons for the limited applications of these systems to date. It also discusses how recent technological advances in fault tolerant control can address these current challenges facing drive by wire application in automobiles. Non-technological issues such as consumer perception of drive by wire systems, trade-off analysis of drive by wire system from Automotive OEMs and suppliers’ perspective are also reviewed in this volume. This book will enhance current understanding of this technology amongst practicing automotive engineers and researchers alike.
