doi:10.3969/j.issn.1008-0198.2022.03.001

Abstract

Abstract: The fault traveling wave technology has been widely used in the transmission network. However, there are obvious differences in the traveling wave transmission process of different power equipment. Therefore, it is necessary to study the characteristics of the power equipment transmission fault traveling wave signal.This paper first analyzes the composition of fault traveling waves in substation, and then analyzes the transmission characteristics of fault traveling waves in typical substation equipment.Finally, the influence of different power components in the substation on the traveling wave signal is analyzed, and the essence of the traveling wave signal of the power equipment transmission fault is revealed.

Key words: transmission network, substation, fault traveling wave, power equipment, transmission characteristics
