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.
