    Rail Transit Substation Automation System
    System introduction
    Main substation secondary system for urban rail transit

    In the centralized power supply mode, each line is equipped with 2 or 3 110kV main substations, including subway, light rail and urban railway.


    • Telecontrol communication management machine and A RTU measuring and control device
    • Relay protection device, fault recorder, little current ground connection system
    • Automatic standby power switch device, frequency voltage emergency control device, security and stability control equipment, oscillation splitting device


    PSCADA system for urban rail transit

    Monitor the combined substations, step-down substations and follow-up substations.


    • PSCADA system, substation protection system and network security device independently developed by DFE have successfully passed the test of China Academy of Railway Sciences and actually been put into operation.
