All operational information and controls are available through these protocols.
However, some communication functionality, for example, horizontal
communication (GOOSE) between the protection relays, is only enabled by the IEC
61850-8-1 communication protocol.
Disturbance files are accessed using the IEC 61850 or IEC 60870-5-103 protocols.
Disturbance files are also available to any Ethernet based application in the standard
COMTRADE format. The protection relay can send binary signals to other protection
relays (so called horizontal communication) using the IEC 61850-8-1 GOOSE
(Generic Object Oriented Substation Event) profile. Binary GOOSE messaging can,
for example, be employed for protection and interlocking-based protection schemes.
The protection relay meets the GOOSE performance requirements for tripping
applications in distribution substations, as defined by the IEC 61850 standard.
Further, the protection relay supports the sending and receiving of analog values using
GOOSE messaging. Analog GOOSE messaging enables fast transfer of analog
measurement values over the station bus, thus facilitating for example sharing of RTD
input values, such as surrounding temperature values, to other relay applications. The
protection relay interoperates with other IEC 61850 compliant devices, tools and
systems and simultaneously reports events to five different clients on the IEC 61850
station bus. For a system using DNP3 over TCP/IP, events can be sent to four different
masters. For systems using IEC 60870-5-103, the protection relay can be connected to
one master in a station bus with star-topology.
All communication connectors, except for the front port connector, are placed on
integrated communication modules. The protection relay is connected to Ethernet-
based communication systems via the RJ-45 connector (10/100BASE-TX) or the
fibre-optic multimode LC connector (100BASE-FX).
IEC 60870-5-103 is available from optical serial port where it is possible to use serial
glass fibre (ST connector) or serial plastic fibre (snap-in connector).
The protection relay supports the following time synchronization methods with a
timestamping resolution of 1 ms.
