Abstract
With the aim of preventing global warming, the Tokyo Protocol, which was adopted in 1997, has become an active part of energy conservation and reduction. In the automobile industry, development of electric vehicles and fuel cell vehicles, as well as development of power storage media such as driving power source and backup power source, have been made considerable progress. On the other hand, in the railroad industry, the electric power storage device is applied as a power source for driving a vehicle, which is represented by a tram line tram, and a power storage device using various electric power storage media for the purpose of voltage reduction measures, Has been put to practical use. Power energy is highly controllable, used for various purposes, and has a variety of uses because of its clean nature. However, because electric energy has the characteristics of production and immediate consumption, it is necessary to have a sufficient supply capacity for the maximum demand electric power for stable supply. Even in the case of electric railways, peak power is large at the time of rush hour, so even if the average load ratio (the ratio of the load power to the electric power facility capacity) is low, it is a factor of the electric power rate increase. In addition, with the introduction of large-capacity new vehicles, the need for efficient use of regenerative energy and countermeasures for line voltage compensation is increasing, and the application of power storage devices can sufficiently cope with these problems. In the case of existing domestic railway vehicles, the regenerative energy generated when braking or decelerating is directly converted to the electric power of the electric cable, which directly affects the electric line. If the voltage exceeds the predetermined voltage range, the regenerative braking battery is used. And thus losses are generated. Therefore, it is urgently necessary to secure the technical ability to store the instantaneous regenerative energy generated in deceleration of the electric motor in the electric power storage medium, to convert the energy into electric energy when necessary, and to improve the efficiency of the energy storage device. This paper focuses on efficient storage method of regenerative energy and analysis of energy storage media in domestic and foreign countries, and examines economic feasibility by applying it to domestic railway industry. Through this, we will create an opportunity to utilize electric power efficiently not only in the railway industry but also in general industry.
