Wang Jingchao: Providing strong support for power grid development

In the power industry for more than 30 years, Wang Jingchao, as a scientific research leader, has always been locked in the forefront of the field of power grid engineering mechanics with his colleagues, leading and inspiring the innovation and development of cadres and employees in the construction and operation of power grids.

Brave research and innovation

In 2005, State Grid Corporation launched the research work on UHV engineering. Wang Jingchao organized and coordinated the research project in the field of power transmission and transformation engineering undertaken by the Institute of Power Transmission and Transformation Engineering of China Electric Power Research Institute (at that time, the Power Grid Center of Guodian Power Construction Research Institute) and presided over Research on the development of 1000 kV AC system transformers and line fittings and the study of ±800 kV DC line fittings, in UHV line fittings, transformers, wire anti-vibration, tower structure and tower foundation A series of technical achievements have been obtained, which have effectively supported the smooth construction and safe and stable operation of the 1000 kV Jindongnan-Nanyang-Jingmen UHV AC pilot demonstration project and the Xiangjiaba-Shanghai ±800 kV UHV DC transmission demonstration project. In February 2013, “UHV AC transmission technology, complete sets of equipment and engineering applications” won the National Science and Technology Progress Special Award.

Wang Jingchao led the research team to comprehensively sort out the engineering mechanics technology in the field of UHV transmission and transformation construction, and put forward a new research direction. Through years of hard work and innovation, it has entered the world's first rank. Further optimized the UHV line fittings and transformers, developed a complete application technology for large-section wires, developed the application technology of large-size angle steel and steel pipes in transmission towers, refined the design technology of foundations, and created a new technology. Substation (conversion station) seismic technology optimizes UHV engineering construction technology. These achievements have been widely used in more than ten UHV transmission projects such as the 1000 kV Huainan-Shanghai UHV AC transmission demonstration project and the Jinping-Sunan ±800 kV UHV DC transmission project.

Proud innovation

The Institute of Power Transmission and Transformation Engineering owns the UHV Tower Test Base of the State Grid Corporation and three key laboratories of the State Grid Corporation. It is the quality inspection and testing center for power engineering materials and components, and the power industry and communication concrete pole quality inspection and testing center. The power industry construction machinery quality testing center affiliated units, the relevant test and testing capabilities have passed the China National Accreditation Service for Conformity Assessment (cnas) laboratory accreditation and the People's Republic of China metrology qualification (cma), its testing methods, testing methods and technical capabilities are It has reached the domestic leading level and the international advanced level, and has contributed to the long-term elimination of unqualified products flowing into the power grid project.

In the past five years, under the leadership of Wang Jingchao, the Institute of Power Transmission and Transformation Engineering has continued to promote scientific research development and capacity building, and has completed a total of 1.202 billion new contracts, providing technical services for the State Grid Corporation system with a total of 63,332 person/days. . In 2014, the Institute of Power Transmission and Transformation Engineering signed a contract value of 305 million yuan and realized an operating income of 245 million yuan.

In the past five years, it has won 2 national science and technology awards, 66 provincial and ministerial level science and technology awards, organized 7 national standards, 21 industry standards, and 37 national grid enterprises. It has obtained 274 national invention patents and national utility model patents. 218 items, 49 software copyright registrations, 30 academic monographs, and 488 core papers.

Great results

Under the leadership of Wang Jingchao, the scientific research project and technological innovation of the Institute of Power Transmission and Transformation Engineering have always focused on the actual needs of the project, based on solving the actual technical problems encountered in the project, and the technological innovation achievements have been widely applied in UHV transmission projects. It has saved a lot of money for national construction and created huge economic and social benefits.
