The 18th International Conference on AC and DC Power Transmission (ACDC 2022) was remotely held recently, where Teng Baichuan, a student studying a master’s degree programme at the Department of Electrical Engineering of the School of Electronic Information and Electrical Engineering of Shanghai Jiao Tong University (SJTU) was awarded the “Best Paper Award - First Prize”, thanks to the guidance of his supervisors Professor Zhu Miao and Assistant Professor Ma Jianjun.
More than 800 experts and scholars, university teachers and students, and technical workers from China, Canada, the United Kingdom, Germany, and other countries attended the virtual conference that attracted over 40,000 viewers.
Introduction to the award
Over 500 papers were contributed to the conference from all over the world, thanks to the strong support of domestic and foreign universities, research institutes, electric power enterprises, and relevant associations. Nineteen award-winning papers, including three papers that won the first prize, were selected after three rounds of review by the paper review committee composed of experts from a number of countries. The paper entitled “Dynamic Fault Reconfiguration of Multi-Port Active Bridge Converter for Reliable Shipboard Bipolar DC System”, produced by Professor Zhu Miao’s team from the Department of Electrical Engineering, won the Best Paper Award - First Prize. The first author of this paper is Teng Baichuan, a student entering the Department of Electrical Engineering in 2021, with Ma Jianjun and Zhu Miao as his supervisors.
A dynamic fault reconfiguration method is proposed for a dual-transformer series-connected active bridge converter with the interconnected dc bus and integrated energy storage devices applied in a shipboard bipolar DC system. The proposed converter can achieve both short-circuit fault-clearing at the source and load ports, thus effectively improving its reliability under complicated conditions. If short-circuit occurs on one of the output terminals connected with the bipolar dc bus, the proposed fault reconfiguration method will enable the faulty terminal to be isolated to maintain the constant power transmission between storage devices and the healthy terminal under the monopolar mode. While if short-circuit occurs on the input terminal connected with storage devices, the proposed fault reconfiguration method will ensure that the supported power feasibly exchanges between two terminals connected to the bipolar dc bus under the source-port fault mode so as to maintain the constant output power of certain terminals. Based on all of the operation modes, the power transmission model and zero voltage switch (ZVS) operation boundaries of all switches are analysed for circuit parameters design. Besides, the control strategies under the bipolar, monopolar, and source-port fault modes are analysed respectfully according to the dynamic characteristics. The performance of the proposed fault reconfiguration method has been tested in the Matlab/PLECS environment in the verification of the converter’s reliability and flexibility.
About ACDC
As an international power transmission conference that has enjoyed a longstanding reputation in the power system area, the International Conference on AC and DC Power Transmission (ACDC) has been held mainly in Europe and has won much recognition and attention from technicians, scholars in research institutions, university researchers and industry experts. This conference was hosted by the IET in collaboration with Tsinghua University and State Grid Shandong Electric Power Company. Eighteen parallel forums were held at the conference for discussions over nine topics, including AC transmission and distribution technology, DC transmission and distribution technology, DC grid technology, power and electronic devices, and power conversion technology.
With the rapid development and engineering practice of China’s electrical engineering, the country has gradually become the focus of the world’s power transmission and distribution technology field. In recent years, to attain the goal of building new power systems, the Department of Electrical Engineering of the School of Electronic Information and Electrical Engineering has carried out research on various basic theories and key technologies in the field of AC/DC power transmission and distribution, which has strongly supported the development of China’s AC/DC power transmission and distribution technology, and helped achieve the national dual carbon goal and build new power systems!
