On December 2, the China Federation of Electric Power Enterprises organized the appraisal meeting of scientific and technological achievements of the “Research on key technologies for the primary and second integration of Digital Power Distribution” jointly completed by Yantai Dongfang Wisdom Electric Co., Ltd. and Yantai Dongfang Wisdom Electric Power Equipment Co., Ltd. Authoritative experts from the Chinese Academy of Engineering, power Grid Companies, scientific research institutes, design institutes, institutions of higher learning and other units formed the Scientific and Technological Achievement Appraisal Committee, Academician Rao Hong served as the director of the appraisal Committee. Xie Jianguo, general manager of the company, attended the meeting and delivered a speech. Deng Wendong, chief scientist and Taishan industry leader, Liu Zhijun, deputy general manager, and other main research personnel of the project team participated in the meeting.
The appraisal committee listened to the report of the project team, reviewed the appraisal materials, and after detailed questioning and discussion, it agreed that: the project has made breakthroughs in key technologies such as the digitization of one or two fusion switches and power distribution terminals, high impedance and high temperature stability resistance voltage dividers, and the overall project results have reached the international leading level.
Digital primary and secondary fusion equipment for power distribution
The concept of “primary and secondary fusion of power distribution” based on electronic transformers was first proposed by the State Grid Corporation of China in 2016. It is an international first. It is technically difficult. In the early stage of implementation, it encountered a series of major technical problems and stagnated. In view of this situation, on the basis of the early research results, WISDOM proposed a set of power distribution primary and secondary fusion solutions based on digital technology, which has been highly recognized by users. Under the leadership of Mr. Deng, with the circuit breaker on the first and second fusion column as the entry point, the project team has overcome difficulties after 5 years of painstaking research, and finally successfully broke through the technical problems, so that the first and second fusion technology of power distribution based on electronic transformers can be fully popularized. This technology is of great significance to improve the lean management of line loss, the level of automation of power distribution, improve the reliability of power supply, and increase the operating efficiency of power grid companies. The identification of “Research on key technologies for the first and second integration of digital power distribution” as the overall international leader is a full affirmation of the work of the project team over the years.
The results of this research have been applied in more than 20 provincial companies of the State Grid and the China Southern Power Grid Company Limited, and have achieved good socio-economic benefits. In the "12 kV Primary and Secondary Fusion Column Circuit Breaker and Power Distribution Automation Terminal (FTU) Standardized Design Plan (2021 Edition)" released by State Grid in March 2021, the digital power distribution primary and secondary fusion plan officially became the recommended standard, and the subsequent "SGCC primary and secondary fusion standardized power Distribution Equipment Technical Specifications" and " SGCC primary and secondary fusion standardized column circuit breaker and ring cage into the network Professional Testing Outline" both have digital solution products. Relevant industry standards are being formulated, and the follow-up results can also be further popularized and expanded in the field of primary and secondary integration of ring cages, with wide application prospects.
WISDOM will focus on “three leading and one first-class”, in-depth implementation of the product leadership strategy of “technological innovation as the guide and customer value as the goal”, in-depth exploration of user needs, consolidate the technological leading position of digital solutions in the power distribution primary and secondary fusion equipment market, and help the company continue to develop steadily, rapidly and by leaps and bounds!
