Instrumentation, Controls & Electrical
Full migration from SPPA-T2000 to
SPPA-T3000 Control System
which is the latest control system generation
and makes unit A5 of the Nikola Tesla A power
plant fit for future operation.
The Result
■ Smooth migration to the
latest control system
generation SPPA-T3000
■ Simplified plant operation
thanks to easy-to-use and
flexible HMI
■ Maximum investment
protection through
retaining existing control
system components
■ Reuse of the replaced
SPPA-T2000 components
as spare parts for Tent A3
and TEK A5
The Plant
The thermal power plant Nikola Tesla A (Tent A)
is located on the right bank of the Sava river,
upstream from Belgrade. It is operated by
Elektroprivreda Srbije (EPS) and consists of six
units with a total electrical output of 1710 MW.
As it is the biggest electric power facility in
Serbia, Tent A is essential for the country´s
electricity supply. On average it produces more
than 8 billion KW hours per year.
The Task
Unit A5 of Tent A was running on SPPA-T2000
Control System since 2004. Instead of ordering
and storing components of the SPPA-T2000
system, EPS wanted state-of-the-art technical
equipment that optimally supports the plant´s lifespan. Thus, the control system at Tent A5 should
be renewed while at the same time protecting
existing investments and avoiding a large-scale
project with long downtime. Additionally, EPS
wanted a more flexible and user friendly HMI to
simplify the work of the operation staff.
Our Solution
Siemens executed in Tent A5 a full migration
from SPPA-T2000 to the latest control system
generation SPPA-T3000. The changeover of the
HMI and the automation level to SPPA-T3000
was executed during a short plant outage.
To migrate the operation and monitoring level,
the previous HMI components were replaced
with a SPPA-T3000 Application Server and Thin
Clients. The operating and monitoring functions
were renewed with the SPPA-T3000 look and
feel, while the existing system installation as
well as engineering and archive data were
retained. The resulting SPPA-T3000 user interface
is defined by its easy-to-use character and
simplifies plant operation remarkably.
The renewal of the control system was concluded
with the migration of the automation level.
I/O modules and cabinets for SPPA-T2000 were
retained, which ensures maximum investment
protection. In addition, the communication and
processor modules were replaced with the
latest generation including a new BMS system
which was realized with fail-safe technology.
While avoiding the disadvantages of a
modernization, the full migration equips unit A5
with state-of-the-art technical components that
ensure safe and reliable future operation.
As an additional benefit, the replaced SPPA-T2000
components are reused as spare parts for
Tent A3 and unit A5 of the Kolubara A (TEK A5)
power plant. Thereby, the lifespan of unit A3
can be extended for another two years.
The migration project was on a tight schedule.
Thanks to Siemens engineering and project
management expertise, it was possible to
replace the HMI components in only 10 days
and finish all works in time.
“The full migration solution made
it possible to renew the control
system at unit A5 without the
disadvantages of a modernization
such as long downtime. Siemens
was a reliable partner and always
present in case of problems.”
