UHV represents voltage levels significantly higher than traditional high voltage, typically starting from 800 kV and above. UHV systems are designed to transmit large amounts of electrical power over extremely long distances with minimal losses. 1. Characteristics
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.
Based on these, ±800 kV is proposed as the rated UHV DC voltage, with a transmission capacity of 6400–8000 MW. The voltage and transmission capacity could form a reasonable differential and create comprehensive technical and economic advantages.
The normal power transmitted by a UHV AC line usually ranges from 3000 to 5000 MW. Using 1000 kV as the nominal voltage can meet the need for long-distance, high-capacity transmission and power exchange; whereas using 1150 kV can increase the maximum power transmitted by the line, but it also increases the cost (15–20% higher than 1000 kV).
In contrast to 500-kV transmission, UHV transmission is significantly advantageous in increasing transmission capacity, reserving land resources, reducing transmission losses, and reducing project investment. 1. Large-capacity transmission.
