The requirements for power networks are continuously evolving. Modern electricity generation, transmission and distribution networks demand high security, high efficiency and good network stability. There is also a shift towards harnessing renewable energy resources. High Voltage Direct Current (HVDC) Transmission technology offers an effective solution to these aspects. HVDC is seen as an attractive option due to its low transmission loss over long distances, its ability to inter-connect asynchronous systems and its fast controllability. It has enabled countries like China, India, the USA and Brazil to harness remote energy resources and convey the energy to large urban centres. It is increasingly being used in Europe and other parts of the world for evacuating power from off-shore wind farms. In North America, it has permitted the interconnection of asynchronous parts of continental networks, which could not have been achievable with traditional ac transmission. The use of HVDC transmission is growing rapidly. For today’s engineer to become proficient in this area requires a knowledge of power engineering, power electronics and control systems. A resource that consolidates these areas is not easy to come by. This book addresses this important need. An excellent book on the subject was published about a decade ago by several of the authors of the current book. However, HVDC is a rapidly growing field and the current book builds on the previous one and includes significant new material as well as an updating of the old material. In particular there is a comprehensive coverage of current and past HVDC projects fromGE Vernova (and all former entities including Alstom) and a modernising of the material on control and protection. The material on valve testing now includes GE Vernova’s latest VTF (valve test facility) in Stafford, UK. A very useful addition is the inclusion of modern methods for the planning of HVDC projects. Indeed, this book is probably the best single knowledge-resource for HVDC transmission and should prove to be invaluable to the university student, the practicing engineer and the expert alike.
