Recently, Premier Li Keqiang of the State Council and Brazilian President Rousseff jointly attended the video groundbreaking ceremony of the beautiful landscape UHV DC transmission project at the Presidential Palace in Brasilia. This project is the first UHV power transmission project won by the State Grid Corporation of China. This move marks a major breakthrough in UHV technology "going out" and is a new important milestone in China-Pakistan power cooperation.

　　

　　 Due to my country's long-term pursuit of local power balance, energy allocation is overly dependent on coal transportation, the proportion of power transmission is low, the structure is unbalanced, and the energy supply chain is very weak. In the past 10 years, more than 70% of the new railway capacity has been used to support the growth of coal capacity. Because of the frequent large traffic jams of coal vehicles on highways, a large number of coal-fired power plants have been shut down every year. This unscientific development method has brought about a series of problems such as rising coal prices, reduced energy efficiency, and traffic congestion, which has become a chronic disease that plagues economic and social development.

　　

At present, the comprehensive strength of my country's manufacturing industry has been greatly improved. "Made in China" has spread all over the world. With its advantages in labor and resources, China is becoming the target of the transfer of capital and production links in labor-intensive industries in the world, thus forming an industrial chain and industrial foundation. . From a domestic perspective, the carrying space of resources and environment is getting smaller and smaller, and the task of transformation and upgrading of "Made in China" is more difficult. It is both very important and urgent to accelerate the climb to the high-end and realize the leap from "Made in China" to "Created in China".

　　

　　The UHV transmission technology led by the State Grid Corporation of China has become the most difficult and complex power technology achievement so far, and the "Chinese Standard" was born. At present, China has compiled 19 relevant international standards in the technical standard system of UHV and smart grids, and has completely independent intellectual property rights. Internationally, China's UHV transmission standard is set as an international standard. This means that competitors from other countries must "connect with China's UHV standards" and must play in accordance with the rules of the game established by China's technical standards, otherwise they will only be out of the competition. UHV is a major technology with independent innovation in my country's energy field, the world's first, with international standard dominance and strong competitive advantages. Like high-speed rail and manned spaceflight, it is an important symbol of national innovation capabilities and comprehensive strength.

　　

　　 As the first UHV power transmission project invested by China abroad, the Miramonti project in Brazil is of great significance in promoting UHV transmission technology, equipment and experience abroad, and promoting China's high-end technology to the world. Therefore, only by firmly grasping the core competitiveness of UHV technology, can we seize the opportunity and expand the larger space to enter the world stage, so that China's UHV can go smoothly and go long-term overseas, and then UHV can become a new era. The well-deserved "national weapon" has become the glory and pride of China's science and technology.
