Comparison study of a 230 KV model substation by EMTP simulation

This paper represents the model of a substation with modern technology which intricate the performing of substations. It is basically a brief comparison of a voltage distribution of all the components of a 230 kV substation with application of external surge, single-line-to-ground fault and internal surge with a presence of external surge included in all of the conditions. The positive sequence and zero sequence resistances are changed accordingly due to variation of the conditions. In this paper the comparison study have been done for different condition of a model of 230 kV substation with the help of ATP/EMTP.
