Field Tests of DC 1500 V Stationary Energy Storage System

초록

The Korean government announced a plan to cut greenhouse gas emissions by 21-30 percent by 2020, as part of the “Business as Usual” (BAU) campaign. The government plans to reduce carbon emissions from the transportation sector by 33-37 percent by 2020. The government is also pushing ahead with the development of eco-friendly transportation systems such as those that use recycled energy. Therefore, urban transit companies should consider incorporating energy storage systems as a means of saving energy. Due to the recent environmental protection trend, which enforces more strict energy savings, every transportation system should reduce energy consumption to the absolute minimum. High-efficiency operation systems, energy saving methods, and CO2 emissions have become vital issues in the railway system, as well as other major public transportation systems [1]. The Korean electric railway system is used to transport several million commuters on a daily basis. There are distinct characteristics to this system, owing to the fact that the vehicles are being driven by electricity, such as variations in displacement and power. Notably, the vehicles generate regenerative power on breaking but some of this power, which cannot be supplied to the other accelerating vehicles, is being wasted
