Omaha Public Power District (OPPD) Awards Substation Automation
Project Implementing UCA Communications.
Omaha Public Power
District (OPPD), a publicly-owned utility in Nebraska, has
selected Tasnet, Clearwater, Florida to provide equipment and
services for their Substation Automation (SA) Project.
Initially, two systems will be purchased and installed before a
similar technology is strategically migrated into their
substations. The first system will be installed in a new OPPD
substation this summer and will integrate intelligent electronic
devices (IED's) using Utility Communications Architecture (UCATM),
Version 2.0, and an Ethernet LAN. UCA 2.0 is a suite of
profiles that allows relaying and equipment monitoring devices
from various manufacturers to communicate over common LAN-based
platforms such as Ethernet. OPPD has selected UCA 2.0/MMS as
The charter goal of
OPPD's SA Project is to further reduce substation capital,
operation, and maintenance costs while maintaining a customer
focus of reliability, low-cost services, and safety. By
adopting common protocols and platforms such as UCA 2.0, MMS,
TCP/IP, and Ethernet, OPPD will take advantage of the economies
of scale of the computer networking and industrial control
industries. Electric Power Research Institute (EPRI) is
sponsoring the development of UCA 2.0. KEMA Consulting, Inc.
provided consulting services to OPPD within an EPRI Tailored
Collaboration (TC) Project.
The Omaha Public Power
District is one of the largest publicly owned electric utilities
in the United States, serving more than 280,000 customers in 13
southeast Nebraska counties. OPPD was organized as a political
subdivision of the State of Nebraska in 1946.
At Wisconsin Electric we recognized a need to change the way we
had traditionally designed our substations. With competition
upon us and the desire to reduce the overall life cycle costs of
substations, we needed better and more timely information from
our substations. The new microprocessor based protective relays
that we were applying had all the information in them that was
required, but we had no means of utilizing that data through
traditional means. We needed a way to get that data to our
operating, maintenance, and system planning personnel systems in
a timely manner.
Tasnet first supplied the traditional RTU for status and control
functions, but replaced the Analog Input section of the RTU with
the SI system. This allowed WEPCO to remove transducers and A/D
converters (high maintenance items) with data retrieved from SEL
relays. In addition, WEPCO was able to remotely access the
relays through the Tasnet supplied NIMs. Local HMIs were
employed using Intouch Wonderware along with the Tasnet Network
Master. This allowed for a very open HMI interface. As the
technology proved to be cost affective, WEPCO ordered additional
systems slowly replacing the RTU with the OPTO-22 and adding
other devices such as Beckwith regulators. The more comfortable
we became with the system the more we began to be the
integrator. Currently WEPCO personal have become trained on
Wonderware and the new US DATA ECS HMI for Windows NT to the
extent that they develop their own HMIs using tools provided by
The Tasnet SI system provided us a way to integrate all of the
IED's so that we could get the information needed to Operating
and other business units in an economical way. In addition to
providing the required data we realized many other benefits. We
were able to reduce the amount of equipment on our relay
switchboards as many items became redundant with this system.
This reduction in equipment resulted in the need for less panels
and thus we were able to reduce the size of the control houses.
We have been able to use the PLC for automatic schemes which
continue to allow us to reduce equipment and wiring in the
One of the keys in the future will be how to manage the
exploding information available so that we can make full use of
our capital asset through better planning and operation of the
distribution system. We believe the substation integration
system will play a significant role in accomplishing that goal
at Wisconsin Electric Power Company.
Lakeland Electric and Water
The City of Lakeland, in
looking for ways to reduce the cost in substation design and
construction, decided to install Substation Integration Systems
in the East Substation and Palmetto Substation. With the Tasnet
SI system we were able to cut out 99% of the wiring for the
analog readings required for SCADA. We now can communicate
directly to an IED which contains all the information and map it
directly to the SCADA system. In reducing transducers we were
able to reduce the number of relay panels in the substations and
reduce the physical size and cost of the SCADA interface. The
remote access feature enables our engineers to remotely access
devices such as relays, and has also reduced the cost of
maintaining the substations. Additionally, it allows the relay
engineers immediate access to fault information.
The East Substation contains the standard Tasnet RTU for status
and controls. The analog data required for SCADA is retrieved
from SEL-221, SEL-321, SEL-251, SEL-501 and SEL-587 relays as
well as Cooper CL-SA regulator controllers. Some controls such
as Regulator Raise, Lower, Auto, Manual and Voltage reduction
are done directly from the IED NIM.
The Palmetto Substation is configured similarly with the
addition of a PLC that allows us the ability to combine over 100
inputs into a major and minor alarm to SCADA. The remote access
then allows the operators with the ability to call into the HMI
for further details when required.
The HMI tools Tasnet created allows us the ability to alter the
original screen Tasnet constructed making this a very open
platform. Creating windows such as enunciator windows was very
easy to do. Although there were some problems integrating new
devices into the system, Tasnet aided. The ability to add any
type device we need allows this system the flexibility and
openness we were looking for.
The City of Lakeland found Tasnet Inc. to be among the leaders
in Substation Integration. They were able to provide numerous
listings of existing systems in the field . Tasnet has been able
to forge good working relationship with most of the IED
manufactures which in turn gives the City of Lakeland an edge in
the competitive electric market. We have had a good working
relationship with Tasnet so far and they have been responsive to
any problems that we have found.
