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 are UHV transmission projects?

UHV transmission projects could effectively alleviate the power demand in eastern regions. They have become key medium- and long-term science and technology projects supported by China. In 2006, the government made specific plans for the infrastructure construction of UHVs.

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.

How effective are UHV transmission lines?

UHV transmission lines feature high transmission efficiency, long transmission distance, low line loss, and flexible power deployment. These characteristics make them effective in overcoming the market segmentation of the power supply caused by the imbalance of China's regional energy resource endowment.

What is the northern Zhejiang-Fuzhou UHV transmission project?

The Northern Zhejiang–Fuzhou UHV Transmission Project is the third UHVAC transmission project built in China after the Southeast Shanxi–Nanyang–Jingmen Project and the Huainan–North Zhejiang–Shanghai Project.

What are UHV projects in China?

UHV projects are the main conduits for regional electricity transmission and are crucial for implementing clean energy transformation strategies that prioritize electricity over conventional energy sources. The development of UHV projects in China can be divided into three main stages: The initial phase (2005–2010): Exploration and Feasibility.
