A Technique for Track Circuit Simulation Comparable with Measured Waveforms for Model-based Fault Detection

Abstract

In the fault detection for track circuits, model-based methods by comparing measured waveforms and fault simulation waveforms may be effective. However, conventional track circuit simulations cannot adequately simulate the characteristics of measured waveforms with multiple frequency components. In this paper, we propose a transient analysis technique for track circuits, which can handle multiple frequency components simultaneously. In addition, we discuss the applicability of the proposed technique to model-based fault detection.
