High Voltage Direct Current (HVDC) power transmission is a technology that allows efficient and flexible transfer of large amounts of electricity over long distances. HVDC systems use direct current (DC) instead of alternating current (AC) for transmitting power, which reduces losses and improves stability and controllability of the power grid. HVDC systems can also interconnect different AC systems with different frequencies and voltages, enabling integration of renewable energy sources and enhancing power security.
One of the leading experts and authors in the field of HVDC power transmission is K. R. Padiyar, who has written several books and papers on this topic. One of his books is HVDC Power Transmission Systems, which was first published in 1990 and has been revised and updated several times since then. The latest edition of this book is the second edition, which was published in 2011 by New Academic Science. This book covers all aspects of HVDC power transmission systems, from basic principles and components to design, analysis, control, protection, operation and applications. It also presents the emerging technology of Voltage Source Converter (VSC)-HVDC links, which use self-commutated converters based on Insulated Gate Bipolar Transistors (IGBTs) instead of thyristor-based Line Commutated Converters (LCCs). VSC-HVDC links offer several advantages over LCC-HVDC links, such as independent control of active and reactive power, lower harmonic distortion, smaller filters, reduced reactive power consumption, black start capability and modular design.
The book HVDC Power Transmission Systems by K. R. Padiyar is a comprehensive and authoritative reference for students, researchers and engineers who want to learn and apply HVDC power transmission technology. The book contains 402 pages and 10 chapters, as well as several appendices that provide additional details on topics such as thyristor and IGBT valves, transient simulation of converters and DC lines, synchronous generator modeling, subsynchronous resonance analysis, CIGRE benchmark models and design of DC and AC voltage controls in VSC-HVDC links. The book also includes several examples and case studies to illustrate the concepts and applications of HVDC power transmission systems.
