Application of regenerative braking energy to Istanbul metro operation system

According to researches, the companies that operate long rail system lines are the major customers of the energy market. Therefore, most of the transportation companies are integrating regenerative braking technologies into railway operation systems. In this study, the application of regenerative braking energy to the operation system of metro transportation in Istanbul is analyzed. The power-supply system of Istanbul Metro is described in detail. The energy data and energy consumption levels in the rail system lines are given and discussed to optimize the energy demand for reducing the operating costs. In addition, the parameters affect the energy saving and regenerative energy in the urban rail operation system are analyzed and discussed.
