I. scheme description

       Shr5000 substation integrated automation system is a new generation of substation integrated automation system designed with modern computer monitoring, communication and network technology according to the operation characteristics of the substation. It is suitable for conventional substation and intelligent substation with 220kV, 110kV and 35kV voltage levels.

       Shr5000 substation automation system consists of super 5000 monitoring system, ud500 series and ud300 series relay protection device, udm500 series process layer merging unit and intelligent terminal device. The system adopts layered distribution and open structure design. The system networking mode is flexible to adapt to different application scenarios. The communication management device has a variety of communication interfaces, which can be easily interconnected with other intelligent devices with different communication interfaces and different communication protocols. Fully support IEC60870-5-103, IEC61850 and other international standards.

       The substation layer of shr5000 system uses 100M Ethernet interface for communication, 1000m interface for network cascade, and flexible communication mode for Bay layer. Multiple network architectures such as Dual Ethernet, single Ethernet, RS485 / RS232 can be selected.
