With the formation of large thermal power base in northwest China and southwest giant hydropower base construction , the need to build a cross-regional , high-capacity , long-range , low-loss UHV national backbone grid . Building the national backbone grid of UHV AC grid by millions of volts level , in line with the urgent need for the rapid development of the national economy of the electric power industry . In this paper, based on the construction of China's first UHV transmission project southeastern Shanxi - Nanyang - jingmen , and 1000kV UHV AC power transmission pilot demonstration project , with the current problems in the transmission and distribution process of building , project quality management theory and empirical research and analysis , implementation and control of the class project has certain reference value .
