"The application of HVDC technology has received new impetus with the evacuation of large quantum of power from remote hydro and thermal stations. In addition, the controllability of power flows in the power grid has added a new dimension to the use of HVDC links in the context of developing Smart Grids. The power transfer from off- shore wind generation is another new application. DC transmission at distribution level voltages (using VSC-HVDC) is also being considered for integration of distributed generation in the power grid. This edition is a complete revision of the first edition taking into account the developments that have taken place since the first edition was published. In particular, the emerging technology ofVSC-HVDC links is described in detail. Instead of adding new chapters to present the new developments, the new material is added at the appropriate places. For example, the analysis ofVSC is presented in chapters 2 and 3 along with the thyristor based Line Commutated Converters (LCC). Practically, in all chapters, there is discussion of VSC-HVDC. The book also presents other developments such as the application of hybrid active filters, capacitor commutated converters, double and triple tuned filters etc. Chapter 10 presents power flow analysis in AC-DC systems based on a novel approach. The modeling, simulation and study of interactions among AC-DC systems is covered in the last 2 chapters without missing any relevant topic. The appendices give details of thyristor and IGBT valves, transient simulation of converters and DC lines, synchronous generator modeling, SSR analysis, CIGRE Benchmark models and design of DC and AC voltage controls in VSC-HVDC links. Several examples and case studies are included to illustrate the concepts. The book is useful as text/reference to students, researchers and engineers from utilities/industries who wish to study and apply HVDC power transmission."--Page 4 of cover.

HVDC is a critical solution to several major problems encountered when trying to maintain systemic links and quality in large-scale renewable energy environments. HDVC can resolve a number of issues, including voltage stability of AC power networks, reducing fault current, and optimal management of electric power, ensuring the technology will play an increasingly important role in the electric power industry. To address the pressing need for an up-to-date and comprehensive treatment of the subject, Kim, Sood, Jang, Lim and Lee have collaborated to produce this key text and reference. Combining classroom-tested materials from North America and Asia, HVDC Transmission compactly summarizes the latest research results, and includes the insights of experts from power systems, power electronics, and simulation backgrounds. The authors walk readers through basic theory and practical applications, while also providing the broader historical context and future development of HVDC technology. Presents case studies covering basic and advanced HVDC deployments headed by world-renowned experts Demonstrates how to design, analyze and maintain HVDC systems in the field Provides updates on new HVDC technologies, such as active power filters, PWM, VSC, and 800 KV systems Rounds out readers' understanding with chapters dedicated to the key areas of simulation and main circuit design Introduces wind power system interconnection with HVDC Arms readers with an understanding of future HVDC trends Balancing theoretical instruction with practical application, HVDC Transmission delivers comprehensive working knowledge to power utility engineers, power transmission researchers, and advanced undergraduates and postgraduates in power engineering programs.
