And we put forward relevant suggestions. The implementation of the scheme has played a positive role model for future similar plants 1000kV UHV Key words: 1000kV UHV; Anhui province power transfer to east; Generator booster transformer; Single-phase four column; Double body structure 摘自《自动化博览》2020年2月刊 |
