The construction of scientific and technological innovation to improve the level of power grid construction For a long time, transmission and distribution construction companies, due to limited allocation of scientific and technological resources and traditional construction habits, basically remained in the state of manpower-based, mechanical-assisted, with high safety risks and poor accuracy during operation. The construction efficiency is low. Most of the construction equipment and innovations developed by construction companies are closed, coping, and simplistic research. The overall level of achievements is not high, and the state of manpower-based construction and labor intensity of construction workers cannot be changed. Has not changed much. In addition, due to the heavy construction tasks and the severe shortage of scientific research funds, the research carried out by the resource platform is not systematic and forward-looking, and the overall level is not high. Therefore, the construction companies generally lack the ability to innovate, and there is a clear difference in the ability to innovate among various enterprises. The research and development level of construction innovation of transmission and distribution companies in developed coastal regions is significantly higher than that of transmission and distribution enterprises in remote and underdeveloped regions.
With the rapid economic and social development, power grid construction has entered a golden age. From the Gobi in Xinjiang to the central plains of China, from the high mountains of Sichuan to the Yangtze River Delta with thousands of lights, a piece of UHV projects such as Yinlong whistled and risen on the Chinese mainland, and a project of a smart grid demonstration project was successively completed. . Jinsu, HuaiShang, HaZheng, and XiZe projects were successively started construction. The Ximeng-Nanjing UHV project has obtained the “Roadâ€, and the ZhunDong-Chengdu ±1100kV UHVDC project has also started preliminary preparation work. The grand blueprint of “Four Matches and Three Straights†has outlined the outlines. During the “Twelfth Five-Year Plan†period, the State Grid Corporation of China will achieve a leap-forward development from ultra-high voltage grids to ultra-high voltage grids and traditional grids to smart grids, and traditional construction methods can no longer fully meet current engineering needs. How to improve the power grid construction capacity and meet the needs of large-scale construction of UHV projects poses a great challenge to the construction technology and equipment level of first-line infrastructure teams.
Accelerating the construction innovation, achieving first-class construction technology, first-class equipment configuration and first-class project management are the answers to the questions. Zheng Baosen, deputy general manager of State Grid Corporation of China, pointed out at the State Grid Corporation of China 2012 mid-year infrastructure construction work conference and construction technology innovation conference that construction technology innovation is an important means to deal with heavy grid construction tasks, realize the leap-forward development of the power grid, and solve major technical challenges. It is a strategic choice to build a strong smart grid with strong resource allocation capabilities, service support capabilities, and ability to withstand risks. A profound technological revolution began quietly.
Construction technology innovation is a long-term system engineering innovation, based on application and inheritance. The continuous promotion and application of innovation results will also continue to enhance the overall technical level of the system construction companies of the State Grid Corporation of China, and ultimately realize the transformation of construction companies from traditional labor-intensive to technology-intensive enterprises.
The standardization of construction technology is the only way to promote the upgrading of power grid construction technology. At present, the traditional construction technology already has the conditions for carrying out standardization operations. The State Grid Corporation of China will carry out construction and technical standardization with emphasis and batches. The 100 results in the "Creation Innovation Technology Achievements Catalogue" have their own characteristics, have good engineering examples and application prospects, have a certain representativeness, but also need to be improved and improved in terms of automation, intelligence and informationization. To meet the modern grid construction requirements.
