ABB AFS Technical solution-In-plant communication

Technical solution

– Intra Substation communication solution

− Utility hardened switches supporting IEC61850

− High number of optical ports required, mainly fiber opti

cal ports (multimode)

− Pure Layer 2 (switched) Ethernet network

− Need for redundant network topology

− Fast redundancy protocol needed (for fast network

recovery time)

− QoS (Quality of Service) and VLANs used to provide per

formance levels needed for Substation Automation

− Management of the network via SNMP

− IEEE1613 compatibility for EMC/EMI

– Communication between Distribution Substations

− FE/GbE backbone for distribution SCADA systems pro

viding data channels e.g. for:- SCADA communication as per

IEC60870-5-104- Voice over IP- CCTV (video)

− High number of electrical ports required, FO ports are

typically singlemode (uplink ports)

− Need for highly secured and reliable communication

− Depending on network design switching or routing func

tionality required

− Need for redundant network topology

− Fast redundancy protocol needed (e.g. MRP/E-MRP)

− Temperature rating of up to +85°C continuous operation

required

− Management System for supervision of the communica

tion network

– In-plant communication

− FE/GbE Backbone for In-plant applications- GbE uplinks for connection to server

− Optical access ports for distances longer than 100m

− Power over Ethernet (PoE)

− Port based rate control

− 802.1x Port Authentication for maximized security on

outdoor cameras

− SNTP (Simple Network Time Protocol) for time distribu

tion down to end devices for accurate time stamping of

video, audio and log files

− Fast reboot after power failure
