A Study of Train Braking Energy for Energy Bank Design

초록

<br>This study was intended to measure the electric power quality of electric railway vehicles in a bid to fundamentally solve the power quality problem. Based a result of comparing and evaluating the measured values, appropriate filter in response to the characteristics of higher harmonics was designed and the high harmonic reduction effect was proven through the simulation test under the environment similar with the vehicles. Particularly, it's designed to improve the reduction effect and make it compact for easy installation.<br> In this study, the test of storing the energy generated during braking operation with the supercapacitor was conducted. Such a method would possibly prevent the occurrence of higher harmonics by regenerative braking and deterioration of power quality as well as minimize the energy loss, thereby accomplishing the eco-friendly railway system. <br>
