Electrical Power Systems

Electrical Power Systems provides comprehensive, foundational content for a wide range of topics in power system operation and control. With the growing importance of grid integration of renewables and the interest in smart grid technologies it is more important than ever to understand the fundamentals that underpin electrical power systems. The book includes a large number of worked examples, and questions with answers, and emphasizes design aspects of some key electrical components like cables and breakers. The book is designed to be used as reference, review, or self-study for practitioners and consultants, or for students from related engineering disciplines that need to learn more about electrical power systems. Provides comprehensive coverage of all areas of the electrical power system, useful as a one-stop resource Includes a large number of worked examples and objective questions (with answers) to help apply the material discussed in the book Features foundational content that provides background and review for further study/analysis of more specialized areas of electric power engineering Front Cover -- Electrical Power Systems -- Copyright Page -- Dedication -- Contents -- Preface -- Acknowledgments -- 1 Introduction -- 1.1 Structure of a Power System -- 1.2 Effects of System Voltage on Efficiency -- 2 The Line Parameters -- 2.1 The Line Resistance -- 2.2 The Line Inductance -- 2.2.1 Inductance Due to Internal Flux -- 2.2.2 Inductance Due to External Flux Linkages -- 2.2.3 Inductance of a Single-Phase Line -- 2.2.4 Flux Linkages in a Group of Conductors -- 2.2.5 Inductance Between Conductor Groups: Self and Mutual Geometric Mean Distance -- 2.2.6 Inductance of Three-Phase Lines Symmetrical Spacing -- 2.2.7 Three-Phase Line With Unsymmetrical Spacing -- 2.3 Transposition of Transmission Lines -- 2.4 Inductance of a Transposed Three-Phase Line -- 2.5 Bundle Conductors -- 2.6 Inductance of a Three-Phase, Double-Circuit Line With Unsymmetrical Spacing and Transposition -- 2.7 Capacitance of Transmission Lines -- 2.7.1 Potential Difference Between Two Points Due to an Electric Charge -- 2.7.2 Capacitance of a Two-Conductor Line -- 2.7.3 Capacitance of a Three-Phase Line With Symmetric Spacing -- 2.7.4 Capacitance of a Three-Phase Line With Unsymmetrical Spacing -- 2.8 Capacitance of a Three-Phase, Double-Circuit Line With Symmetrical Spacing -- 2.9 Effect of Earth on the Capacitance of Transmission Lines -- 2.10 Effect of Earth Capacitance of a Single-Phase Line -- 2.11 Capacitance of Three-Phase Line Including Effect of Earth -- 2.12 Skin Effect and Proximity Effect -- Worked Examples -- Problems -- Questions -- 3 Mechanical Design -- 3.1 Sag and Tension Calculations -- 3.2 Approximate Relations for Sag and Tension -- 3.3 Conductors Supported at Different Levels -- 3.4 Effect of Wind on Sag -- 3.5 Effect of Ice Coating on Sag -- 3.6 Conductor Materials -- 3.6.1 Stranded Conductors -- 3.7 Vibrations of Conductors Front-matter_2017_Electrical-Power-Systems Copyright_2017_Electrical-Power-Systems Dedication_2017_Electrical-Power-Systems Preface_2017_Electrical-Power-Systems Acknowledgments_2017_Electrical-Power-Systems 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 further reading Index_2017_Electrical-Power-Systems
