On the National Science and Technology Award Ceremony on January 18, 2013, "UHV AC transmission key technology, equipment and engineering application" won the National Award for S&T Progress (Special Prize), the highest award SGCC has obtained so far. It is also the highest National S&T Progress Award in China's electro technical area, realizing ¡°Created by China¡± and ¡°Led by China¡± in this field worldwide.
¡¡UHV AC transmission represents the highest level in international high-voltage transmission. To research and develop this technology, we should overcome two problems. One is the world-class technology challenge between insulation and electromagnetism with high voltage and strong current. The other is the impact of harsh natural environment with heavy pollution and high altitude. Innovation is extremely difficult. The project involves the research of 180 key topics and the development of 9 categories of key equipment over 40 kinds. Combining production, learning, research and application, innovation breakthroughs have been achieved in voltage control, external insulation configuration, the electromagnetic environmental control, the development of complete sets of equipment, system integration and test capacity. The project gained 96 invention patents, mastered the core technologies of UHV AC transmission, and successfully developed a full range of key equipment.
China¡¯s influence in international electro-technology has significantly improved. Our UHV standard voltage has become the international standard. The International Electro technical Commission (IEC) said that China's UHV power grid project is an important milestone in the history of the electric power industry.
