Description
Summary:碩士 === 中原大學 === 電機工程研究所 === 81 === This paper studies the fault current distribution for a transmission system with overhead lines and some sections of underground cables. There were seldom studies to analyze the influences of cable juntions to a global grounding network. In this paper, we used an application of "Decoupled Method" [1,2] to calculate the fault current distribution at the large scale interconnection grounding network, meanwhile, discussed the grounding current, division factor, and relative problems. From the study results, shown that the several factors of cable junction deserved to be taken into account for determin- ing a reasonable division factors. The methods for increasing the division factor and for enhancing grounding safety are also simutaneously proposed here.
