HV power transmission is advantageous in that it has large transmission capacity, long transmission distance, high efficiency, and low loss. The development of UHV power transmission technology and the building of smart grids with UHV networks as the backbone are conducive to the intensive development of large hydropower, coal power, nuclear power, and renewable energy bases, optimizing resource allocation within a larger range, easing pressure on the environment, and saving precious land resources. As such, it exhibits remarkable economic and social benefits which are consistent with China’s actual conditions and national energy development strategy. The development of UHV power transmission has been incorporated into the Outline of the 11th Five-Year Plan for the National Economic and Social Development of the People’s Republic of China, and the Outline of the National Program for Long- and Medium-Term Scientific and Technological Development (2006
2020), making it an important component of the national energy development strategy.In 2005, the State Grid Corporation of China (SGCC) adhered to self-dependent innovation and initiated studies onkey technologies and the feasibility of UHVAC and DC transmission projects with a rigorous and scientific attitude.SGCC organized a number of entities in China engaged in scientific research, design, manufacturing, and construction fields, and colleges and universities to carry out comprehensive study on key technologies of UHV transmission, covering the system stability, electromagnetic environment, overvoltage and insulation coordination, characteristics of external insulation, equipment manufacturing, test technology, and operation. Meanwhile, the SGCC launched technical exchanges and consultations with relevant international organizations and made fruitful achievements which have been implemented,  applied, and verified in design, construction, operation, and equipment manufacturing of UHV projects.
