Book Description
The only book on the market that provides current, necessary, and comprehensive technical knowledge of extruded cables and high-voltage direct-current transmission This is the first book to fully address the technical aspects of high-voltage direct-current (HVDC) link projects with extruded cables. It covers design and engineering techniques for cable lines, insulation materials, and accessories, as well as cable performance and life span and reliability issues. Beginning with a discussion on the fundamentals of HVDC cable transmission theory, Extruded Cables for High-Voltage Direct-Current Transmission: Advances in Research and Development covers: Both the cable and the accessories (joints and terminations), each of which affects cable line performance The basic designs of HVDC cables including a comparison of mass insulated non-draining cables with extruded HVDC cables The theoretical elements on which the design of HVDC cables is based highlighting the differences between HVAC and HVDC cables Space charge-related problems that have a critical impact on extruded insulation for HVDC application Recent advances in extruded compounds for HVDC cables such as additives and nano-fillers The improved design of extruded HVDC cable systems with emphasis on design aspects relevant to accessories Cable line reliability problems and the impact on cable system design Including more than 200 illustrations,Extruded Cables for High-Voltage Direct-Current Transmission fills a gap in the field, providing power cable engineers with complete, up-to-date guidance on HVDC cable lines with extruded insulation.

Book Description
Presents the latest developments in switchgear and DC/DC converters for DC grids, and includes substantially expanded material on MMC HVDC This newly updated edition covers all HVDC transmission technologies including Line Commutated Converter (LCC) HVDC; Voltage Source Converter (VSC) HVDC, and the latest VSC HVDC based on Modular Multilevel Converters (MMC), as well as the principles of building DC transmission grids. Featuring new material throughout, High Voltage Direct Current Transmission: Converters, Systems and DC Grids, 2nd Edition offers several new chapters/sections including one on the newest MMC converters. It also provides extended coverage of switchgear, DC grid protection and DC/DC converters following the latest developments on the market and in research projects. All three HVDC technologies are studied in a wide range of topics, including: the basic converter operating principles; calculation of losses; system modelling, including dynamic modelling; system control; HVDC protection, including AC and DC fault studies; and integration with AC systems and fundamental frequency analysis. The text includes: A chapter dedicated to hybrid and mechanical DC circuit breakers Half bridge and full bridge MMC: modelling, control, start-up and fault management A chapter dedicated to unbalanced operation and control of MMC HVDC The advancement of protection methods for DC grids Wideband and high-order modeling of DC cables Novel treatment of topics not found in similar books, including SimPowerSystems models and examples for all HVDC topologies hosted by the 1st edition companion site. High Voltage Direct Current Transmission: Converters, Systems and DC Grids, 2nd Edition serves as an ideal textbook for a graduate-level course or a professional development course.

Book Description
Power and communication cables are frequently installed adjacent to each other, and hybrid cables that contain both power conductors and communication lines are increasingly popular. Power and Communication Cables is a convenient, single-source volume written for utility maintenance engineers, cable production and design engineers, and students to expand their knowledge of both types of cables in the power and communications fields. With contributions from leaders in the field, this book presents a detailed treatment of solid-liquid, polymeric, compressed gas, and cryogenic cables used in power transmission and distribution. In the area of communication, the contributors address the use of metallic conductor multipair and coaxial cables, as well as optical fiber cables. Power and Communication Cables provides in-depth discussion of the design, manufacture, testing, installation, and operation of power and communication cables. You will find essential information on the properties of materials and learn how they influence cable characteristics. Moreover, this interdisciplinary reference provides theoretical and practical insights into various aspects of cable engineering in both power and communication systems.
