| Abstract: | Asymmetric high-voltage pulse track circuits are widely applied in track sections with poor shunting conditions. To address the lack of mature mathematical or circuit models for pulse signals, this study develops a wideband simulation model of the asymmetric high-voltage pulse track circuit. This model allows for exhaustive simulation of various operational scenarios, thereby providing foundational support for simulation-based analysis of pulse track circuits. Firstly, the high-voltage pulse signal undergoes characteristic analysis to construct a simulation circuit for the pulse signal source. Next, theoretical calculations determine the impedance parameters of the frequency-dependent components like rails within the track circuit system. A wideband model is then established using vector fitting method combined with circuit synthesis theory. Subsequently, a wideband model for asymmetric high-voltage pulse track circuits is constructed based on the system architecture for simulation analysis. The model's accuracy and robustness are validated through field measurement data and rail surface voltage tests. Finally, transmission characteristics analysis is performed based on this simulation model, including the effects of ballast resistance and transmission distance on the receiving-end voltage and track surface voltage along the line.
