  • Doubly Fed Induction Machine

    John Wiley & Sons Inc Doubly Fed Induction Machine

    Book SynopsisThis book will be focused on the modeling and control of the DFIM based wind turbines. In the first part of the book, the mathematical description of different basic dynamic models of the DFIM will be carried out. It will be accompanied by a detailed steady-state analysis of the machine. After that, a more sophisticated model of the machine that considers grid disturbances, such as voltage dips and unbalances will be also studied. The second part of the book surveys the most relevant control strategies used for the DFIM when it operates at the wind energy generation application. The control techniques studied, range from standard solutions used by wind turbine manufacturers, to the last developments oriented to improve the behavior of high power wind turbines, as well as control and hardware based solutions to address different faulty scenarios of the grid. In addition, the standalone DFIM generation system will be also analyzed.Table of ContentsPreface xiii 1 Introduction to A Wind Energy Generation System 1 1.1 Introduction 1 1.2 Basic Concepts of a Fixed Speed Wind Turbine (FSWT) 2 1.2.1 Basic Wind Turbine Description 2 1.2.2 Power Control of Wind Turbines 5 1.2.3 Wind Turbine Aerodynamics 7 1.2.4 Example of a Commercial Wind Turbine 9 1.3 Variable Speed Wind Turbines (VSWTs) 10 1.3.1 Modeling of Variable Speed Wind Turbine 11 1.3.2 Control of a Variable Speed Wind Turbine 15 1.3.3 Electrical System of a Variable Speed Wind Turbine 22 1.4 Wind Energy Generation System Based on DFIM VSWT 25 1.4.1 Electrical Configuration of a VSWT Based on the DFIM 25 1.4.2 Electrical Configuration of a Wind Farm 33 1.4.3 WEGS Control Structure 34 1.5 Grid Code Requirements 39 1.5.1 Frequency and Voltage Operating Range 40 1.5.2 Reactive Power and Voltage Control Capability 41 1.5.3 Power Control 43 1.5.4 Power System Stabilizer Function 45 1.5.5 Low Voltage Ride Through (LVRT) 46 1.6 Voltage Dips and LVRT 46 1.6.1 Electric Power System 47 1.6.2 Voltage Dips 50 1.6.3 Spanish Verification Procedure 55 1.7 VSWT Based on DFIM Manufacturers 57 1.7.1 Industrial Solutions: Wind Turbine Manufacturers 57 1.7.2 Modeling a 2.4 MW Wind Turbine 72 1.7.3 Steady State Generator and Power Converter Sizing 79 1.8 Introduction to the Next Chapters 83 Bibliography 85 2 Back-to-Back Power Electronic Converter 87 2.1 Introduction 87 2.2 Back-to-Back Converter based on Two-Level VSC Topology 88 2.2.1 Grid Side System 89 2.2.2 Rotor Side Converter and dv/dt Filter 96 2.2.3 DC Link 99 2.2.4 Pulse Generation of the Controlled Switches 101 2.3 Multilevel VSC Topologies 114 2.3.1 Three-Level Neutral Point Clamped VSC Topology (3L-NPC) 116 2.4 Control of Grid Side System 133 2.4.1 Steady State Model of the Grid Side System 133 2.4.2 Dynamic Modeling of the Grid Side System 139 2.4.3 Vector Control of the Grid Side System 143 2.5 Summary 152 References 153 3 Steady State of the Doubly Fed Induction Machine 155 3.1 Introduction 155 3.2 Equivalent Electric Circuit at Steady State 156 3.2.1 Basic Concepts on DFIM 156 3.2.2 Steady State Equivalent Circuit 158 3.2.3 Phasor Diagram 163 3.3 Operation Modes Attending to Speed and Power Flows 165 3.3.1 Basic Active Power Relations 165 3.3.2 Torque Expressions 168 3.3.3 Reactive Power Expressions 170 3.3.4 Approximated Relations Between Active Powers, Torque, and Speeds 170 3.3.5 Four Quadrant Modes of Operation 171 3.4 Per Unit Transformation 173 3.4.1 Base Values 175 3.4.2 Per Unit Transformation of Magnitudes and Parameters 176 3.4.3 Steady State Equations of the DFIM in p.u 177 3.4.4 Example 3.1: Parameters of a 2 MW DFIM 179 3.4.5 Example 3.2: Parameters of Different Power DFIM 180 3.4.6 Example 3.3: Phasor Diagram of a 2 MW DFIM and p.u.

    Book SynopsisCommunications technologies increasingly pervade our everyday lives, yet the underlying principles are a mystery to most. Even among engineers and technicians, understanding of this complex subject remains limited. However, there is undeniably a growing need for all technology disciplines to gain intimate awareness of how their fields are affected by a more densely networked world. The computer science field in particular is profoundly affected by the growing dominance of communications, and computer scientists must increasingly engage with electrical engineering concepts. Yet communications technology is often perceived as a challenging subject with a steep learning curve. To address this need, the authors have transformed classroom-tested materials into this accessible textbook to give readers an intimate understanding of fundamental communications concepts. Readers are introduced to the key essentials, and each selected topic is discussed in detail to promote mastery. EngTable of ContentsPreface. 1 An Overview of Computer Communications.

The adaptive transceiversexamined employ powerful turbo codecs, turbo equalisers andspace-time codecs, equipping the reader with a future-prooftechnological road map. It demonstrates that adaptive transceiversare capable of mitigating the channel quality fluctuations of thewireless channel as a lower-complexity alternative to space-timecoding. By contrast, if the higher complexity of multipletransmitters and multiple receiver-assisted systems is deemedacceptable, the advantages of adaptability erode. * Provides an in-depth introduction to channel equalisers andKalman filtering and discusses the associated complexity versusperformance trade-offs * Introduces wideband near-instantaneously adaptive transceiversand studies their performance both with and without turbo channelcoding * Describes how to optimise adaptivTrade Review"...provides an overview of near-instantaneously adaptive transceivers."

  • Reliability Survivability and Quality of Large

    John Wiley & Sons Inc Reliability Survivability and Quality of Large

    Book SynopsisCompetition within the telecommunications companies is growing fiercer by the day. Therefore, it is vital to ensure a high level of quality and reliability within all telecommunications systems in order to guard against faults and the failure of components and network services. Within large scale systems such quality and reliability problems are ever higher. The metrics of Quality and Reliability have to date only been available in journals and technical reports of companies which have designed or produced major parts of systems used in large applications. This book provides a self-contained treatment enabling the reader to be able to produce, define and utilise the metrics of Quality and Reliability required for the design and implementation of a large application such as a world class event as the Olympic Games. An additional outcome is that this book can be used as a guide for producing an ISO standard for large scale Systems such as the Olympic Games. * Provides Table of ContentsList of Contributors.
