Modelling and Analysis of Currents Flowing in High Voltage Power Substations During Ground Short - Circuits

摘要

This article presents a method for determining the distribution of ground short-circuits in high voltage substations, in particular determining the value of currents flowing into substations grounding. Knowledge of these currents is important to assess the risk of electric shock hazard within the substation area. The EMTP-ATP program was used in the research, in which the structure of the analyzed systems was created. The results of calculations made for a selected high voltage substation in various work configurations are presented.
