Electrified railway/metro system needs a reliable and strong power supply system. The power automation system is the “brain and nervous system” of the power supply.
SIFANG provides the complete automation solution to electrified railway/metro power supply system.
The power automation system consists of the following layers
• Control Center Layer
Energy management system with SCADA and dedicated advanced applications are used for whole or regional railway power system. It monitors, controls and manages the railway power system in power control center based on a remote communication system between the control center and substations.
• Station Layer
A substation automation system is applied in traction stations and switch stations. The system performs the station SCADA functions and communicates with control center. It monitors, controls and manages primary equipment and bay layer intelligent electronic device (IED) in station. The operator in control center is able to do the same function via station automation system.
• Bay Layer
The layer mainly consists of various IEDs, such as protection relays, automatic control devices and other intelligent devices, which can communicate data to station control layer via Ethernet or field bus.
Powerful automation software with SCADA and special advanced function designed for railway power system.
Reliable and excellent IED dedicated to railway power system
DC protection IED for DC power supply system of metro
Fast and accurate tripping based on advanced innovation of the heterogeneous impedance feeder protection and comprehensive harmonic restraint principle of transformer differential protection IED.
Precise fault location, recording and reporting for fault analysis.
Automatic recognition of the actual operating conditions according to the needs of the remote control scheduling with time synchronization.
