Abstract: The Static Inverter (SIV) failed occurs on the mainline of the EMU. It must be repaired and reset by the main work shop after the passenger evacuation, which will result in great loss in operation. The main purpose of this study is to find the root cause which influences the SIV abnormal performance. Through fault tree analysis (FTA) method and laboratory test, we found that sensor feedback is the main factor, not the SIV device self. The improvement is to add the limiter device at the position after the ramp starting in the current controller output. The voltage command will not rise rapidly when the static inverter (SIV) starts, then it will be verified by following the validation steps in the laboratory. These results can be used for reference in other railway systems. Whether it is a Static Inverter (SIV) in the form of GTO or IGBT, Inverter AC Over-Current (IAOC) issues can be solved.

Abstract: This study is based on the straight-line acceleration section and the occurrence of the jitter position on the operational routes, five sections are selected for the general survey, and then one section is selected for monitoring and analysis purposes. In addition, we try to find whether the corrugation phenomenon of the curved rail section affects the train or not? In this way, the steel wheel turning can be redefined, and the process should focus on the arc relationship; the Taoyuan MRT route, combined with multiple curved and long steep slopes routes, those will cause the rails corrugation, and the frequency of the steel wheel out of round is much higher than other MRT systems.
