A Study on the Guidelines for Demand Factor of Electrical Facilities in Subway Stations
초록
The electric facilities for subway stations require reliable and safe electricity in spite of their load increases rapidly. Nevertheless, Korea Electrical Safety Corporation reports that the accidents of independent electric facilities increased greatly from 4,632 cases in 1998 to 6,024 in 1999 and 6,776 cases in 2000, while the ratio of the accidents related with transformers grew gradually. As it is, it is deemed very important to minimize the spreading effects of the electric system accidents and thereby, enhance reliability of the electric supply as well as its safety. According to the fact that the electric facilities for subway stations are important for the public safety and conveniences, it should be careful to set their capacity instead of simply applying the general capacity standard to them, and thereby, improve their economy as well as prevent their accidents. With such a basic conception in mind, this study is aimed at analyzing the characteristics of the electric load in the subway stations and thereupon, suggesting some guidelines for setting of the electric facility capacity for subway stations in terms of optimal operation and safety.
