Book Description
The UHV transmission has many advantages for new power networks due to its capacity, long distance potential, high efficiency, and low loss. Development of UHV transmission technology is led by infrastructure development and renewal, as well as smart grid developments, which can use UHV power networks as the transmission backbone for hydropower, coal, nuclear power and large renewable energy bases. Over the years, State Grid Corporation of China has developed a leading position in UHV core technology R&D, equipment development, plus construction experience, standards development and operational management. SGCC built the most advanced technology 'two AC and two DC' UHV projects with the highest voltage-class and largest transmission capacity in the world, with a cumulative power transmission of 10TWh. This book comprehensively summarizes the research achievement, theoretical innovation and engineering practice in UHV power grid construction in China since 2005. It covers the key technology and parameters used in the design of the UHV transmission network, shows readers the technical problems State Grid encountered during the construction, and the solution they come up with. It also introduces key technology like UHV series compensation, DC converter valve, and the systematic standards and norms. - Discusses technical characteristics and advantages of using of AC/DC transmission system - Includes applications and technical standards of UHV technologies - Provides insight and case studies into a technology area that is developing worldwide - Introduces the technical difficulties encountered in design and construction phase and provides solutions

Book Description
The direct current transmission scheme linking the island of Gotland to the main land of Sweden by means of a submarine cable under the Baltic Sea is the first commercial realisation of a modern technique for the transmission of electrical energy. It is certainly not accidental that this pioneering initiative was allotted to the Gotland scheme. Various viewpoints may be presented regarding this, but the essential factor relates to the circumstances that permitted the magnitude ofthe transmitted power to be given a value which would not have been technically or economically feasible for any other project. The power, on the one hand, was sufficiently small to justify the risk associated with such a new venture, for it fell within limits acceptable both to ASEA as the manufacturer and to the Swedish State Power Board as the customer. On the other hand, the power was large enough to demonstrate the technical and economic characteristics of the new system and to provide the opportunity of gaining invaluable experience that could be applied to future large-scale transmission systems. In 1954 a team under the direction of Dr. Uno Lamm successfully commissioned the Gotland scheme, representing the culmination of many years of intensive development work.
