Construction of UHV Demonstration and Test Projects in China

The UHV AC and DC demonstration lines and test bases, several first UHV projects in China, are under construction. The UHV key technologies research achievements can be directly used in the construction of the test lines and test bases, the former research achievements can be validated; the equipment can be applied and tested. Hence, the test lines and bases have the abilities to validate the prophase research achievements in China, the performance and reliability of the equipment, which are very important for the design, operation and maintenance of future UHV projects in China. The design parameters and construction of UHV AC, UHV DC test and demonstration lines, UHV AC, DC test bases of SGCC are introduced in this paper.
