Summary:Recently, there has been an increasing interest in energy saving operations in railway systems due to its significant advantages compared with strategies that involve the enhancement of hardware instruments. The authors focus on Automatic Train Operation (ATO) as a suitable method to evaluate the effects of energy-saving operation under simple conditions. The difference from other previous works is that the authors aim to conduct substantiative experiments on track and design explicitly-considered energy-saving operations. The authors perform on-track tests to measure the efficiency of the motors on trains and the measured values are used for numerical calculation to enhance accuracy. In this study, an energy-saving ATO is designed and installed in rolling stocks. This designed ATO consists of the three following methods: The first method is to install coasting in speed profiles and decrease the maximum speed by jerk regulation. The second method is to use power-limiting braking in the braking section and increase the regenerative energy. The third method is to update the notch control algorithm for using the motor effectively. The authors perform on-track tests to evaluate the energy-saving effect of the proposed method compared with conventional running profiles.
