Study on Power Supply Design and Fault Response for Subway Signal

As for the significance of the signal system power supply in the whole urban rail transit, it should be guaranteed that power supply design is reasonable to cope with power supply faults in order to ensure the stability and reliability of power supply quality and the safety and efficiency of train operation. The paper dealt with the design principles and related technical specifications and standards of signal power supply, enumerated some current design schemes of signal power supply for urban rail transit, and put forward an optimal design. Furthermore, protection measures and fault response methods were pro- posed to safeguard train operation.
