Abstract
This paper introduces the analysis process of a 500 kV substation DC system inter-pole short circuit fault.In order to deeply explore this special kind of DC insulation fault,based on the balance bridge principle of the DC insulation monitor,a circuit model of the DC inter-pole short circuit is established,and the process of obtaining the short circuit resistance of mutual short circuit is given.By calculating and analyzing the relationship between the control bus voltage and the short circuit resistance during DC inter-pole short circuit,the characteristics of DC inter-pole short circuit are summarized to provide reference for handling similar DC system faults.关键词
