Abstract

Computer-aided loadflow and fault analyses of mine power systems are routinely conducted to ascertain system performance and also to provide information to assist in the protection and coordination of these systems. Three-winding transformers are frequently encountered in mining applications, typically at continuous miner and longwall sections where there exists a need for dual utilization voltages. These transformers are often modelled as a three bus system neglecting the secondary to tertiary winding impedance and the effect of base changes. This paper analyzes the impact of more accurate transformer models on voltages and fault currents which are realized from loadflow and fault studies of mine power systems.
