On January 9, the CPC Central Committee and the State Council held the 2016 National Science and Technology Award Conference in the Great Hall of the People. State Grid Corporation of the declaration of the "dynamic process of interconnected power grid security and key technologies and applications" won the first prize of progress in science and technology, "± 800 kV UHVDC converter valve key technology and application of" won the second prize of National Technological Invention , "Key Technology and Application of Prevention and Control of Large Contaminated Flashover in Power Grid" "Key Technology and Application of New Energy Generation and Dispatching Operation" "Key Technology and Application of Power Supply with High Reliability in Distribution Network" "In-Oil Gas Detection of Transformer Latent Defects" Technology and Application "and other seven achievements won the second prize of national science and technology progress. The number of national science and technology awards won the highest record level in history.
National Science and Technology Award Power Electric and NUCI first prize has been vacant for two consecutive years, this year the company declared "the key technology and application of dynamic safety of interconnected power grid technology" projects come to the fore, won the award first prize. This project has overcome three major problems of dynamic power analysis and control in transmission section, voltage stability assessment and control of terminal grid and dynamic simulation in multi-time scale and formed three key technologies, two prevention and control systems, one set of simulation software As one of the interconnected power grid dynamic process of security technology system, the overall reached the international advanced level. The results have been widely used in our country, effectively guarantee the safe operation of interconnected power grids, and are also used in power grid safety analysis in countries such as Brazil to enhance our country's international influence in related fields with remarkable economic and social benefits.
The project of "Key Technology and Application of ± 800 kV UHVDC Converter Valve" has made a series of innovations in such fields as integrated control of multi-physics, thyristor series broadband equalization, strong electromagnetic environment triggering and protection, and multi-stress equivalent test. Out of China's first independent intellectual property rights of UHV valve, and in Jinping to Sunan and other six UHV DC project to achieve large-scale applications, the leading international comprehensive technical indicators.
The project of "Key Technology and Engineering Application of Prevention and Control of Large-scale Pollution Flashover in Power Grid" has constructed a complete technical system from dynamic wide-area pollution map, external insulation configuration scheme, a new generation of composite insulators to anti-fouling technology of electric porcelain. Achievements in the State Grid Corporation has been fully applied to achieve the anti-pollution flashover technology route updates and upgrading of organic external insulation; in the serious air pollution and the recent haze multiple cases, successfully curbed the large-scale pollution flashover.
The project of "key technologies and applications of new energy power generation and dispatching operation" pioneered the method of predicting the fluctuation of new energy power fluctuation characteristics clustering and identification, multi-model interactive verification and integration, proposed a new energy stochastic optimal scheduling method considering risk constraints , A three-layer active power control method with long and short cycle coordination, a wind power / PV LVR technology based on active protection / fast phase-locking was invented. A two-stage reactive power voltage coordination control method was proposed to adapt to new energy power fluctuation and fault crossing Safety and stability control methods.
In order to solve the problem of high reliability power supply in distribution network, a multi-voltage level coordination and optimization power supply theory was established and the methods of complex fault identification and fault recovery resource efficiency Dynamic assessment method, breaking through the distribution network and user-side distributed power / load coordination and control optimization techniques, the development of the corresponding hardware devices and software systems.
"Transformer latent defects in oil gas detection technology and application" project, belonging to the National Science and Technology Progress Award workers, farmer technology innovation projects, by the Jiangsu Provincial Electric Power Experimental Research Institute Co., Ltd. completed first-line technicians, the company following the 2011,2014 After winning the annual award, re-winning the group reward shows that the company insists on promoting mass innovation plays an important role.
In addition, North China Power Grid Co., Ltd., North China Electric Power Research Institute Co., Ltd. involved in the "large turbogenerator subsynchronous resonance / oscillation control and protection technology, equipment and application" project, the State Grid Xinjiang Electric Power Company to participate in the "wind turbine Key control technology innovation and industrialization "project, the State Grid Gansu Provincial Power Company to participate in" large-scale wind turbine hydro-generator low frequency fault diagnosis of key technologies and applications "project by the State Science and Technology Progress Award.
Up to now, the company has won a total of 60 national science and technology awards, of which one Grand Prize, seven first prizes and 52 second prizes.
