Based on the mathematical model of traction network and overvoltage generation mechanism of urban rail transit test track and AC electrification test track, through software simulation and field data analysis, the technical scheme of induction overvoltage suppression and the device of induction overvoltage suppression are designed and put forward. Induction overvoltage suppression technology reduces the impact of AC traction network on DC traction power supply system and electromagnetic induction of urban rail transit test track, ensures the safety of DC traction power supply equipment and metro vehicles, makes AC locomotives and urban rail transit vehicles test non- interference, safe, reliable and orderly. It provides some reference and guidance significance to the planning, design and operation management of intercity railway and urban rail transit.
