Function and Design Idea of UHV DC Test Base

The function orientation of UHVDC test base subordinated to State Grid Corporation of China (SGCC) is in the service of UHVDC power transmission and transformation projects, especially the power transmission from West China to East China, and to promote the domestic manufacturing of UHVDC power transmission equipments. In essentials, this test base consists of UHVDC test transmission line, corona cage, outdoor test site, test hall, pollution and environment testing laboratory, electromagnetism environment simulaiton test site, insulator testing laboratory, arrester testing laboratory and equipment live examine site. In this paper the experimental research capability and design idea of the test base are presented; the mian peformance parameters of above- mentioned experimental facilities are given; the problems to be considered in the site selection as well as planning and design of the test base are summarized to offer over all technical support for ±800 kV and ±1000 kV DC power transmission projects.
