摘要
基于中国电源和负荷分布的特点以及将来电源组成的变化,分析未来不同时期特高压电网结构形态与电源组成的相互关系,讨论未来中国特高压电网不同结构形态的适应性和安全性。结合中国间歇性电源不断增加和能源互联网发展趋势,展望2030年和2050年前后过渡期和远景中国特高压电网需要的结构形态,指出将来特高压直流电网安全运行所面临的严峻挑战,以及中国特高压电网结构形态的变化趋势和面临的关键技术问题。
The relationship between structural form of ultra-high voltage（UHV）power grid and power source in the future are analyzed based on the current distribution characteristics of power and load in China and the prospective change of power source composition.Further,the adaptability and security of different structural forms of UHV power grid in the future of China are discussed.Then,the UHV power grid structural forms in the transition period of 2030 and the prospect period of 2050 in China are prospected by combining with the continuous increase of China＇s intermittent power supply and the development trend of Energy Internet.As followed,the severe challenges for the safe operation of ultra-high voltage direct current（UHVDC）power grid in the future are pointed out,and the variation trend and key technical issues of UHV power grid structural forms in China are illustrated.
