Overview
■ Customer: ElectraNet
■ Sector: Electricity Transmission
■ Project name:
Clare North Substation
■ Country: Australia
■ Highest system: 145 kV
Facts about the project
Siemens has delivered an Australian
first in substation automation for the
South Australian transmission company
ElectraNet. ElectraNet owns, operates
and manages the South Australian transmission system, which is part of the
National Electricity Network covering
the East Coast of Australia and Tasmania.
The project comprised of a full turnkey
control/protection system with portable
building, protection and control panels
(SIPROTEC 4 and various 3rd party IEDs
(Intelligent Electronic Devices)), SICAM
PAS substation automation system and
all other substation related auxiliary equipment for ElectraNet’s Clare North Project.
In addition, Siemens has supplied the
entire high-voltage, highly integrated gasinsulated switchgear (HIS) for Clare North.
This is Electranet’s first IEC 61850 project,
and in fact the first IEC 61850 project
to be ordered by any Australian transmission utility.
The Clare North project was based on
a ‘functional’ or outcomes based specification. Siemens and ElectraNet worked
in close collaboration to develop the
detailled design and ensure the design
of the Clare North control system met
the desired design outcomes.
IEC 61850 is the communication standard
for substation automation as a basis for
protection, control, measurement and
monitoring functions. It also provides the
means for high speed substation protection
applications, interlocking and intertripping.
The implementation of the IEC 61850
protocol provides ElectraNet with a fully
integrated electrical system that meets
local and international standards.
Description of overall system
In this ENEAS (Efficient Network and
Energy Automation Systems) solution,
Siemens designed, manufactured, supplied, installed and commissioned all
components, including a substation automation system, ancillary equipment and
portable switchroom. As an additional
benefit, ElectraNet used the control room
as a training facility for staff before its
final installation at Clare North substation.
The control system is based on the SICAM
PAS substation automation system and
includes the SIPROTEC range of IEDs as well
as various 3rd party IEDs. In the project,
the capabilities of the existing Ethernet
communication network were also maximized to provide the highest levels of
security and stability for all of the IT architecture. GOOSE messaging was used
extensively in the design of the Clare

Intertripping, Auto-reclose, CBF, CB Status
and IED Isolation were all implemented
via GOOSE. The required engineering
was completed using resources at both
Siemens Ltd. Australia (Energy Division)
and Siemens in Germany. The implementation of Siemens’ modular and specifically configured 145 kV 8DN8 outdoor
gas-insulated switchgear (HIS) has enabled ElectraNet to maximize the use of
space within the substation’s perimeter.
ElectraNet will reap the cost benefits by
it’s application of the Siemens HIS equipment due to the low lifecycle costs, as
this equipment is essentially maintenance-

ensure a long service life – the first major
maintenance inspection of the switchgear
is not due until 25 years into its service life.
