What is ultra-high-voltage electricity transmission (UHV)?

Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers.

What is UHV technology?

The UHV technology offers the distinct advantage of being able to transfer high amounts of power over long distances at a very low current value, thereby minimising transmission line losses. China plans to combine long-haul UHV DC lines with a UHV AC backbone to help distribute the power to regional consumers.

What is UHV power grid interconnection?

Power grid interconnection through UHV power transmission lines optimizes the resource allocation across a wider spectrum and increases the power supply to the receiving-terminal load centers in the eastern region.

What is ultra-high voltage (UHV)?

Ultra-high voltage (UHV) refers to power transmission lines operating at voltages greater than 800 kilovolts (kV). The such high-voltage operation has a high capacity and manages to transmit electricity over long distances with minimal power loss.

What are the advantages and disadvantages of UHV power transmission?

Compared with high voltage (HV) transmission technology, UHV power transmission has the advantages of large transmission capacity, long transmission distance, and low line loss (Liu 2015). The Jindongnan-Nanyang-Jingmen UHV transmission line is the first UHV alternating current transmission project in China.

What is UHV power transmission?

UHV refers to voltage levels with direct current over ±800 kV and alternating current over ±1000 kV. Compared with high voltage (HV) transmission technology, UHV power transmission has the advantages of large transmission capacity, long transmission distance, and low line loss (Liu 2015).
