Introduction

1 Introduction
ABB Ability
Smart Substation device designed for protection, control, measurement and supervision
of utility substations and industrial switchgear and equipment. The design of the device
has been guided by the IEC 61850 standard for communication and interoperability of
substation automation devices. It is fully integrable with Relion series IEDs for creating a
complete solution. Optional functionality is available at the time of order for both software
and hardware, for example, special application packages and additional communication
modules.

Communication

The IED supports the IEC 61850 standard and its specified GOOSE, MMS and SAV/SMV
communication profiles. Operational information and controls are available through these
protocols.
The IEC 61850 communication implementation supports all monitoring and control
functions. Additionally, parameter settings, disturbance recordings and fault records can
be accessed using the IEC 61850 protocol. Disturbance recordings are available to any
Ethernet-based application in the IEC 60255-24 standard COMTRADE file format. The
IED can receive binary signals from other devices (so-called horizontal communication)
using the IEC 61850-8-1 GOOSE profile, where the highest performance class with a
total transmission time of 3 ms is supported. Furthermore, the IED supports receiving of
analog values using GOOSE messaging.
The IED meets the GOOSE performance requirements for class P1 (10 ms) tripping
applications in distribution substations, as defined by the IEC 61850 standard.
The IED can support five simultaneous clients for IEC 61850 MMS reporting. The IED
supports receiving sampled analogue measurements according to IEC 61850-9-2LE from
up to 20 Merging Units or other IEDs.

Ethernet redundancy

IEC 61850 specifies a network redundancy scheme that improves the system availability
for substation communication. It is based on parallel redundancy protocol PRP-1 defined
in the IEC 62439-3:2012 standard. The protocol relies on the duplication of all transmitted
