On June 26, 2014, State Grid Corporation of China organized and convened the acceptance meeting of the “Research on deicing method of split conductor current transfer” project in Changsha, Hunan. The fourth generation intelligent deicing device of electric transmission line split conductor current transfer jointly researched and developed by our company and Chongqing University and Hunan Electric Power Research Institute has been passed the project acceptance successfully. The group chairman Min Hong, director of academician workstation Xingliang Jiang, and expert Zhijing Zhang attended the project acceptance meeting. According to the contract requirements of State Grid Corporation of China, the research team has carried out the laboratory simulation for several years and the collection analysis of the test data under the natural environment of Xuefeng Mountain in Hunan, and the project obtained multiple technical breakthroughs. The acceptance expert group agreed that, the research achievements reached the international advanced level in the aspects of gas liquid two-phase flow model in the process of split conductor icing, split conductor current deicing model, and split conductor grouping deicing control strategy. The materials and technology had been improved for four times. The device would provide more reliable, more accurate and more powerful guarantees for the safety operation of the electric power system.
