[Abstract]:In this paper, the special transfer test technology of main equipment of UHV substation and related digital simulation modeling technology are studied in Huainan to Shanghai UHV AC transmission demonstration project. The problem of electromagnetic interference in local partial discharge test space of AC UHV transformer is solved, and the accurate location of fault in AC UHV GIS field voltage test is realized, and the problem of AC / DC interference in testing parameters of AC / UHV dual circuit line is solved. The excitation transformer used in the field partial discharge test of the UHV main transformer was optimized and designed to complete the field handover test of the first 1 000 kV on-load voltage regulating main transformer with innovative ultra high voltage (GIS) 1 100kV field voltage test band. And completed the test key equipment optimization configuration technology research.
