要約(英語): This paper focuses on energy saving in traction of rolling stocks and discusses the application of energy-saving driving operation. Increasing the maximum acceleration rate of a rolling stock is proposed using which energy-saving running is achieved by decreasing the powering energy because of the decreasing the rate of powering in the total running time and decreasing maximum speeds. The authors performed on-track tests and obtained 6.0% energy-saving effect by applying the proposed method against conventional running profiles, and 4.8% of that against the previously proposed running profiles without increasing the acceleration rate. The effectiveness of increasing acceleration rate is proven by on-track tests as well as numerical evaluations. Besides, this paper focuses on energy-time plots used for optimization of running profiles that visualize the relationship between energy consumption and running time, and gives a more practical description than optimal running time scheduling. Many on-track tests with various speed profiles were performed during this research. In order to understand the relationships of energy-saving effects of many speed profiles easily in practical use, the authors focus on the difference of the energy-saving effects of the many sections and many test runs, and graphically display relationships between the differences of energy consumption and that of running time. The visual presentation enables a straightforward analysis of the relationship among running time and speed profiles.
