On April 17, the UHV flexible DC transmission technology seminar organized by the Global Energy Internet Development Cooperation Organization was held in Beijing. Experts and scholars attending the conference focused on the status quo of flexible HVDC transmission technology, engineering practices, development trends, major difficulties, and economic aspects. Exchanges and discussions to jointly promote the development of UHV flexible DC transmission technology.
At the seminar, Liang Xuming, the technical director of the cooperation organization, introduced the latest research results of the cooperative organization, the Global Energy Internet backbone network planning, and based on the global energy Internet construction requirements, elaborated on the key technical requirements for UHVDC flexible and flexible transmission and plans. He suggested , Adhere to the collaborative research of all parties involved in production, education, and research, as soon as possible to break UHV large capacity converter valve, DC circuit breakers, voltage converters, DC cables and secondary control protection and other UHV core equipment and key technologies, to further improve the reliability evaluation of DC power grid And related standards system construction, improve the technical economy of flexible direct current transmission.
From the State Grid Corporation of China DC Construction Department, Operation and Maintenance Department, Chinese Academy of Electric Power, State Grid Economic Research Institute, State Grid Joint Research Institute, Nan Rui Jibao, Nanfang Power Institute, Zhejiang University, Western Electric Group, ABB More than ten experts and scholars from the Group, Zhuzhou CRRC and other units (departments) introduced the latest research results, discussed the progress of technology, and conducted in-depth exchanges on the development trend, difficulties, and economy of UHV flexible DC transmission.
It is understood that ultra-high voltage flexible DC transmission technology is a major innovative technology for achieving large-scale global clean energy development and transmission, access to weak AC systems, and improving the transmission efficiency of the transmission corridor. The cooperation organization was held at the 2018 Global Energy Internet Conference recently. The released "Global Energy Internet Technology and Equipment Innovation Action Outline (2018-2025)" proposes that in order to promote the key issues facing the construction of the global energy Internet, especially the backbone network backbone, it is necessary to break through the ±800 kV UHV multi-end flexible DC directly. DC circuit breakers and other DC transmission technology.
