Ultra high voltage power grid development in China

The Chinese Nanyang-Jingmen 1000 kV UHV AC demonstration project began commercial operations in early 2009. Multiple 1000kV AC and 800kV HVDC transmission lines are part of the transmission expansion plan up to the year 2020. The transmission expansion plan is the result of a comprehensive analysis of China's economic development, generation expansion forecasts, and power flow import and export requirements. This paper describes the current and future development of the UHV power grid in China. Further research and development efforts are being pursued.
