Dear Experts and Scholars:

The transformation of the energy structure and the large-scale development and utilization of renewable energy sources prompted the grid system to start a new round of major changes, especially the rapid development of new technologies represented by multi-terminated flexible DC transmission and distribution technology, which has continuously given rise to a large number of new types of power equipment. At the same time, the working scene of the electrical power equipment is quite complicated, and it usually involves the coupling of multi-physical field during the insulation and discharge. Additionally, the electromagnetic field and the plasma discharge have strong interaction with the materials. Therefore, these difficulties result in a long R&D and design cycle for current power equipment with high R&D costs. Whether a more accurate computation method can be obtained to shorten the design and development cycle of power equipment and reduce the development cost is an important issue that researchers have been facing for a long time. In addition, most of the current computation software for electric power equipment comes from foreign companies, and it is urgent to develop a computation and analysis platform for electric power equipment with independent intellectual property rights.

With the introduction of analytical methods from many disciplines such as electromagnetism, heat transfer, mechanics, and atomic-molecular physics, understanding of the complex physical processes involved in various electric power equipment has been deepened. Meanwhile, the rapid development of emerging technologies such as artificial intelligence and big data in recent years creates new opportunities for the development of insulation and discharge computation of electric power equipment.

To this end, Electrical Contact and Arc Committee of China Electronical Society, Power Transmission and Transformation Equipment Committee of China Electronical Society, Engineering Dielectric Committee of China Electronical Society, Power Transformation Committee of Chinese Society for Electrical Engineering,  Plasma and their Applications Committee of China Electronical Society, IEEE PES Working Group of Digital Twins for T&D Power Equipment, and IEEE PES Wuhan Chapter will jointly host the 4th International Symposium on Insulation and Discharge Computation for Power Equipment. The conference will be held in Wuhan, China from May 26th to 28th, 2023 (the location will be at the Hongshan Hotel), with the support of National Natural Science Foundation of China (NSFC) and Chinese Electrotechnical Society. The conference was jointly organized by Wuhan University, Xi'an Jiaotong University, Xi'an High Voltage Apparatus Research Institute Co., Ltd, State Key Laboratory of Power Grid Environmental Protection and Engineering Research Center of Lightning Protection & Grounding Technology, Ministry of Education. If the national or local government makes other arrangements for epidemic prevention, the conference schedule will be adjusted accordingly and a notice will be issued in time.

The conference will comprehensively explore the achievements and latest progress in the field of insulation and discharge computations of electric power equipment, discuss the opportunities, challenges, and future development direction of the field, advocate the development of China's independent computation and design software, devote to strengthen the academic exchange between peers in electric power equipment computation, establish a platform for cooperation between industry, university and institutes, promote the communication and contact with other disciplines and industries in the related field, and finally aim to develop the power equipment design and manufacturing technology in China. The Organizing Committee sincerely invites colleagues from academies and industries all over the country and warmly welcomes overseas colleagues to visit.  The conference will establish 10 outstanding paper awards and oral presentation awards for young researchers and graduate students, and each winner will be awarded an honorary certificate and prize money.
