한국형 고속열차 보조전원 시스템의 신뢰성 해석

In this paper, to assess and enhance the reliability of Korea High Speed Train, auxiliary power is selected and reliability analysis is carried out. The auxiliary power system is classified into subsystems and functional analysis is conducted. Reliability block diagrams are drawn and reliability parametric analysis is performed. Analysis results show that the reliability of auxiliary power system depends on critical items. To grow the system reliability, activities have been concentrated on improvement of critical items and the results were successful.
