UNBALANCE ANALYSIS ON ELECTRIC RAILWAY SYSTEM USING PSCAD/EMTDC

초록

This study presents the AC railway system modeled by PSCAD/EMTDC in detail. The model made by PSCAD/EMTDC has a lot of advantages. It could be available for the system change, simulated repeatedly and also applied regarding very complicated systems. PSCAD/EMTDC models for voltage unbalance analysis of electric railway system that transfers electric powers through Scott-transformer from KEPCO's 154kV transmission line are developed. In order to verify model's validity, we compare simulation results with simple hand calculation results. It is confirmed that the model made by PSCAD/EMTDC is correctly designed.
