碩士 === 國立臺灣科技大學 === 電機工程系 === 102 === This research investigates the model of the propulsion system of trains for high capacity Taipei MRT system. The model is used to simulate the integrated DC rapid transit traction power supply system with multiple trains based on actual MRT operation characteristics and to analyze the dynamic load behavior using MATLAB/Simulink. The system model includes multiple trains running in three stations. The cases of multiple trains under different headways, i.e 60 sec, 90 sec, and 120 sec are simulated. Current sharing between 1st train and 2nd train is identified. The result shows that headway 60s has the biggest current sharing from both, 6.11 kA at 123rdsec (2nd train to 1st train) and 2.92 kA (1st train to 2nd train) at 167th sec. Whereas, headway 120s has the smallest current sharing from both, 5.1 kA at 125th sec (2nd train to 1st train) and 2.42 kA (the 1st train to 2nd train) at 167th sec. The voltage on the third rail in different cases shows that headway 90s has the highest voltage, 941.77 volt. The smallest value of voltage is 533.29 volt, also happened in headway 90s, followed by headway 60s (550.38 Volt) and headway 120s (584.99 Volt).
