UHV power transmission refers to the power transmission technology with voltage levels of AC 1000 kV and above, and DC ± 800 kV and above.
The development of ultra-high-voltage (UHV) AC and DC power transmission technology, to meet the future large-scale power base for long-distance, has made large-scale delivery possible. In the development of UHV AC transmission at the same time, ultra-high-voltage DC (UHVDC) transmission is also gradually affirmed.
The power demand increases rapidly in China; however, the areas of huge power demands are of long distance from most areas of abundant energy resource in the country. Therefore, China put in great effort to develop ultrahigh voltage (UHV) power transmission systems to optimise its energy allocation.
It is concluded that China obtained mature experience in developing, constructing, and operating UHV systems and successfully realised long-distance, large-capacity power transmission, and the UHV power transmission technology has become an important measure for energy allocation in large areas. 1. 2.
Therefore, the reliability and safety requirements of UHV technology and equipment are very stringent. According to the National Power Reliability Index of 2023 released by China's National Energy Administration, the energy availability rate of the UHVDC transmission system is 96.847 %, showing a continuous improvement in reliability.
At present, power transmitted through UHV accounts for 1/4 of the power load in eastern and central China. Additionally, 70 % of the electricity transmitted through the UHV project is generated from clean energy.
