UHV Power Transmission Advantages

1. It can meet the needs of large-scale, long-distance, and high-efficiency power transmission. The characteristics of reverse distribution of energy resources and load centers in my country are obvious. Most of the energy resources are located in the western and northern regions, and the load centers are concentrated in the central, eastern and southeastern regions. The distance between large energy bases and load centers can reach 1000~3000km. Therefore, To ensure the intensive development of large-scale energy bases and the reliable transmission of electricity, it is necessary to vigorously develop UHV transmission technology with the characteristics of large transmission capacity, long distance and high efficiency.

2. It is beneficial to protect the environment. The use of UHV power transmission can promote the intensive development and efficient utilization of clean energy, and transport clean energy such as hydropower in southwestern my country, wind power in northwest and northern regions, and solar power generation to large-scale and long-distance load centers in the east, central and southeast. , to achieve "electricity comes from afar, clean electricity", reduce fossil energy consumption and pollutant emissions, with significant environmental benefits. 

3. It is beneficial to improve the safety of power grid operation. The use of "strong AC and strong DC" UHV AC-DC hybrid power grid transmission can greatly reduce the problems of insufficient power flow transfer capability and weak reactive voltage support in the 500kV power grid in the event of a DC system failure, reduce the risk of large-scale power outages in the power grid, and can provide for the next generation of power grids. It can create conditions for the gradual layered and partitioned operation of the power grid, solve the problems that limit the development of the power grid such as short-circuit current exceeding the limit, and improve the flexibility and reliability of the power grid operation.

4.It is beneficial to improve the comprehensive social benefits. Compared with high-voltage and ultra-high-voltage power transmission, the use of UHV power transmission can save a lot of power transmission corridors, significantly improve the transmission content per unit corridor width, save valuable land resources, and improve the overall utilization efficiency of land resources.
