Simulation of An Economical Run for High Speed Train

고속철도 차량의 경제 주행 시뮬레이션

This paper presents an simulation methdology for determining an economical running pattern for a high speed train which minimizes energy consumption under an given trip time margin. The economical running pattern is defined with an economical maximum speed in traction phase, a speed at the end of coasting and a speed at the end of regenerative braking alone in braking phase. An economical run for subways is also described. As a case study, the simulation is carried out fer an economical run of high speed NamSeoul-Pusan line, and the results described. To do this, train performance simulation program is built and extended to be able to find an economical running pattern and then to simulate the defined economical run.
