Construction of UHV AC test base of SGCC

SUMMARY In order to research ultra high voltage (UHV) transmission technology systematically, State Grid Corporation of China launched the UHV AC test base project to provide strong technical support for UHV grid construction. The facilities including UHV power supply, UHV test lines, equipments qualified field, electromagnetic environmental laboratory, climate laboratory, UHV corona cage, impulse test field were built at the test base. Much useful experience had been achieved through the construction and research in the fields of UHV electromagnetic environment, external insulation characteristic, equipment technical requirements, equipments manufactory, electrical design, construction, test, and operation. It accelerated the construction of the UHV pilot project of China. Copyright © 2011 John Wiley & Sons, Ltd.
