It was learned on July 10 that the world's first ± 800 kV / 6250 ATS HVDC converter valve developed by State Grid Smart Grid Research Institute successfully passed all type tests. The converter valve delivery capacity than ± 800 kV / 5000 amp valve increased by 25%, to further improve the delivery efficiency, significant cost savings in the world to create the same product flow capacity of the most. This is another major achievement made by China in the field of direct current transmission, further consolidating the state-of-the-art technology of SGCC in this field. In recent years, the State Grid Chi Institute rely on the national "second Five-Year" science and technology support program and the State Grid Corporation of key scientific and technological projects to overcome a number of key issues in the field of HVDC transmission technology, successfully developed ± 800 kV / 5000 A UHVDC converter valve. In 2014, the institute launched the research and development of a 6250 A-HVDC DC converter valve to overcome various technical problems such as control of electrical loss caused by the substantial current increase, temperature uniformity of components and resistance to electromagnetic disturbance, and so on. Current levels of UHVDC converter valves. Next, the State Grid Institute of intellectuals will speed up the conversion of this type of converter valve and project demonstration application research to meet the company's UHVDC construction needs for our larger-scale delivery of clean energy to provide technical support.
