Transmission Lines Earth-fault Phase Selection Criterion Research
摘要
Abstract
This paper studied the transmission lines when earthing fault phase selection criterion.Found in the land and because zero mode formed between three-phase wire loop and by the resistivity and other factors,the attenuation characteristics and line mode weight not consistent,use existing obtained may occur phase-selection miscalculation.This paper puts forward through comparing various modulus wavelet modulus maxima relations and then judge method,is don't use only criterion equation of mould component,eliminating the line.The influence of zero mould component through the simulation,the correctness of verified criterion.关键词
