2015 National Science and Technology Award Conference held Five achievements of the company won the second prize of national science and technology progress On January 8, the CPC Central Committee and the State Council held the 2015 National Science and Technology Award Conference in the Great Hall of the People. State Grid Corporation of the declared declaration of the Qinghai-Tibet Power Grid project, the grid lightning protection key technologies and applications to prevent large AC / DC power grid blackout of rapid control and fault isolation technology and application of three achievements won the second prize of progress of science and technology , Two multi-timescale precision control technologies for high-power special power supplies and their series of product development and key technologies, complete sets of equipment and industrialization of ultra-large turbine control system and other two achievements were awarded the second prize of national science and technology progress. Up to now, the company has got 51 national science and technology awards, among which, there are 1 Grand Prize, 6 first prizes and 44 second prizes. The achievements of scientific and technological innovation of the company are highly recognized by the state and the whole society. The Qinghai-Tibet Power Grid interconnection project is the world's highest elevation, the largest alpine region, the longest crossing through the permafrost region, the most difficult construction of transmission and transformation projects along the average 4650 meters above sea level, the highest 5300 meters, 550 kilometers across the permafrost . The project tackled the key technical problems of DC external insulation and high altitude correction of the electromagnetic environment, the tower foundation construction of transmission line in permafrost regions, operational control and security and defense under the conditions of "strong direct current and weak alternating current" grid systems, and established the project of high altitude power grid project The technical system for vegetation restoration has achieved a breakthrough in the clinical treatment of altitude sickness caused by high-altitude and long-distance power transmission lines, and has resulted in zero death, zero disability and zero plague dissemination. The successful construction of the project has ended the history of isolated power grid operation in Tibet and solved the long-term power shortage problem in Tibet Power Grid. It has played an important role in maintaining border stability, national security and protecting the ecological environment. The key technologies and applications of lightning protection in power grids were completed. The system completed the key technical research on four aspects of lightning flash monitoring, lightning discharge mechanism, overhead line differential protection and lightning fault monitoring, and innovated to form a set of theoretical models, monitoring systems, protective devices and standards One of the lightning protection system of power grid technology to enhance the overall level of lightning protection, the overall technical level of the international leader. The past three years, the company lightning transmission system failure rate dropped 50%, guiding the disposal of more than 6800 lightning strikes, power grid lightning protection effect is significant. The results are still in the Beijing-Shanghai high-speed rail, Beijing, Tianjin and other urban rail transit traction system to promote the application, lightning failure rate reduced by 70%, significant economic and social benefits. To prevent the large-scale blackout in AC / DC hybrid power grid technology and application of rapid control and fault isolation, AC-DC power grid to create a fault propagation analysis theory, developed a set of prevention and control decision support software; invented the coupling based on matching DC multi-objective coordinated control technology, developed a coordinated control system of AC and DC; proposed precise positioning method of oscillation center of power grid, developed a fast fault isolation device; constructed an AC / DC hybrid integrated active prevention, optimization coordination and rapid response control Grid rapid security control system. The project achievements have provided strong support for the protection of the safety of China's power grid and realized the international leading of the rapid safety control technology of the super large AC / DC hybrid power grid. During the "13th Five-Year Plan" period, the Company will continue to implement the strategy of "innovation-driven development", conscientiously implement the "13th Five-Year Plan" for science and technology planning and vigorously implement collaborative innovation around the three core directions of UHV, smart grid and clean energy transportation and consumption , Original innovation, speeding up the breakthrough of strategic emerging technologies, actively promoting technological leaps and bounds from technology to technology, and providing strong technical support for the complete establishment of "one strong, three best" modern companies and building a global energy Internet.
