Jian Liu, Professor, Xian University of Technology, China and Chief Engineer at Shaanxi Electric Power Research Institute, China Professor Liu received his Ph.D. in Electrical Engineering from Xi'an University of Technology, Xian, China. After graduation, he worked as an engineer at the Northwest Electric Power Corporation, as senior engineer at the Shaanxi Electric Power Corporation and Chief Engineer at the Shaanxi Electric Power Research Institute, respectively. Professor Liu started his research on distribution system and its automation in 1995. He established China's first urban Distribution Automation System (DAS) in Yinchuan Province. He published the paper 'The uniformed matrix algorithm of fault location for distribution systems' which was the country's first paper on fault location for distribution systems. He has published over 100 papers on modelling, analysis, planning, fault location, service restoration, network reconfiguration, feeder automation and self-healing for distribution systems. As the head of the DAS Testing Group of the State Grid Corporation of China, Prof. Liu established the DAS testing laboratory and has developed sets of simulation and testing equipment, and he has led and or supervised the testing work of over 80 DAS projects in China. He supervises all of the DAS standards of State Grid Corporation. Due to his contributions to electric power engineering, Prof. Liu has been awarded the national and provincial level of science and technology prizes on twelve occasions. He is a Senior Member of IEEE.
