A Study on Static Inverter of TTX(Tilting Train eXpress)

초록

The railway system will be improved in terms of the maximum speed, passing speed at a curve, and passing speed at a turnout while considering the safety and ride quality. A railway system comprises various components such as the railway car, track, traction power, signals and communication, etc. that work together. For increasing the speed, aspects such as the powering performance, braking performance, running stability, power reception stability, signal and security system, ride quality, and noise, etc. must be improved. Developed countries are already actively engaged in attempting to maximize the speed of their railway systems. Recently, TTX has been trial running on Chung-buk commercial line after accomplishing the factory test. The total measurement system (hereafter DAQ-Data Acquisition system) has been operated to estimate performance of train. The DAQ system developed by domestic technology is the most progressed system among the others. In this paper, a measurement system, which is time synchronized with the DAQ system and evaluates the various signal from controllers, sensors and each equipment, is studied. The reliability and safety of SIV has been improved by this measurement system.
