Study on Shunt State of Track Circuit Based on Transient Current
Authors: , ,
Abstract: Track circuit is considered to be one of the means of train detection, its shunt state often misjudged due to the shunt malfunction. Aim at the influence of shunt malfunction on the shunt state of track circuit, a detection method for the shunt state of track circuit according to the transient current was proposed. And the time response of track circuit was obtained by the precise time-integration method. The truncation error is efficiently decreased by interlacing the voltage and current nodes along the x-axis. Taking the boundary conditions of track circuit in adjusting and shunting state, changes of the receiving end current was simulated. The results show that the precise time-integration is unconditional stability, which is an effective method for analysis of track circuit and the transient current when a train entering or clearing a track section, which can be regard as an important information for the shunt state of track circuit.
