DC Electric Train Traffic Scheduling Method Considering Energy-Saving—Combination of Train Traffic Parameters for Larger Regenerative Power

Abstract

In recent yeas, various transportation systems have been asked to reduce the energy consumption and so the railway systems are without exception. So far, because the calculation of energy consumption and optimization of the railway systems is so difficult, it is hesitate to consider the effective utilization of the regenerative powers. In this paper, we propose a new simple scheduling method for railway systems that positively utilize the regenerative powers. The main idea is use the areas of the overlap between one train's driving partial and another train's braking partial in a diagram to estimate the regenerative powers. Based on the estimated regenerative powers, we can evaluate some important travel parameters in train traffic scheduling and make up an appropriate train traffic diagram. The simulation results show the proposed method is useful. © 1999, The Institute of Electrical Engineers of Japan. All rights reserved.
