18. Station communication
The relay supports a range of communication protocols includ-
ing IEC 61850 Edition 2, IEC 61850-9-2 LE, Modbus® and DNP3.
Operational information and controls are available through
these protocols. However, some communication functionality,
for example, horizontal communication between the relays, is
only enabled by the IEC 61850 communication protocol.
The IEC 61850 protocol is a core part of the relay as the protec-
tion and control application is fully based on standard model-
ling. The relay supports Edition 2 and Edition 1 versions of the
standard. With Edition 2 support, the relay has the latest func-
tionality modelling for substation applications and the best in-
teroperability for modern substations. It incorporates also the
full support of standard device mode functionality supporting
different test applications. Control applications can utilize the
new safe and advanced station control authority feature.
The IEC 61850 communication implementation supports moni-
toring and control functions. Additionally, parameter settings,
disturbance recordings and fault records can be accessed us-
ing the IEC 61850 protocol. Disturbance recordings are avail-
able to any Ethernet-based application in the standard COM-
TRADE file format. The relay supports simultaneous event
reporting to five different clients on the station bus. The relay
can exchange data with other devices using the IEC 61850 pro-
tocol.
The relay can send binary and analog signals to other devices
using the IEC 61850-8-1 GOOSE (Generic Object Oriented Sub-
station Event) profile. Binary GOOSE messaging can, for exam-
ple, be employed for protection and interlocking-based pro-
tection schemes. The relay meets the GOOSE performance

requirements for tripping applications in distribution substa-
tions, as defined by the IEC 61850 standard (<10 ms data ex-
change between the devices). The relay also supports the
sending and receiving of analog values using GOOSE messag-
ing. Analog GOOSE messaging enables easy transfer of analog
measurement values over the station bus, thus facilitating for
example the sending of measurement values between the re-
lays when controlling parallel running transformers.
The relay also supports IEC 61850 process bus by sending
sampled values of analog currents and voltages and by
receiving sampled values of voltages. With this functionality
the galvanic interpanel wiring can be replaced with Ethernet
communication. The measured values are transferred as
sampled values using IEC 61850-9-2 LE protocol. The intended
application for sampled values shares the voltages to other
615 series relays, having voltage based functions and 9-2 sup-
port. 615 relays with process bus based applications use IEEE
1588 for high accuracy time synchronization.
For redundant Ethernet communication, the relay offers either
two optical or two galvanic Ethernet network interfaces. A
third port with galvanic Ethernet network interface is also
available. The third Ethernet interface provides connectivity
for any other Ethernet device to an IEC 61850 station bus in-
side a switchgear bay, for example connection of a Remote
I/O. Ethernet network redundancy can be achieved using the
high-availability seamless redundancy (HSR) protocol or the
parallel redundancy protocol (PRP) or a with self-healing ring
using RSTP in managed switches. Ethernet redundancy can be
applied to Ethernet-based IEC 61850, Modbus and DNP3
protocols.
