Analysis on the effect of harmonic frequency for interlocking system according to the ITX operation (ICCAS 2013)

Abstract

Interlocking system is the device by which devices such as the signal, point machine and track circuit, et � . can be operated by linking mutually with the logic generated mechanically, electrically or . by software for � af : an� rapId train operation and vehicle shunting within the station yard. In c � se whe � e th � re .IS any ma . lfunct � onmg m . the interlocking system due to the effect of harmonics according to the tram operatIOn withm the electncal railway sectIO � , serious problems such as the rear-end collision of train and discontinuation of train .operation, etc. can be occu � red. This paper presents results through test criteria and methods to check whether harmomcs to be g : nerated accordm � � o th . e train operation on electrical railway section of Gyeong-chun Line have effect � on the i � terlockmg system : In addlt � on, It checked if harmonics according to the train operation have effects on the mterlockmg system to be mstalled m the signal machine room.
