OVERHEAD MEDIUM VOLTAGE TWISTED INSULATED CABLEMODELS FOR THREE-PHASE POWER FLOW ANALYSIS

This paper proposes a modified Carson method for modeling 20 kV overhead medium voltage twisted insulated cables (MVTIC) commonly found in the distribution systems in Lampung Province, Indonesia. Different cable sizes are considered in this work. Results are then compared to those obtained from OpenDSS and ETAP (with SPLN library). The sequence impedances obtained from the method are then utilized in the developed three-phase power flow software to analyze a real medium voltage distribution feeder consisting 119 buses and serving rural area
