State-of-the-art control systems
at Tusimice II for high efficiency –
now and in the future
Reference – Control System
Instrumentation, Controls & Electrical
SPPA-T3000 Control System
ensures improved efficiency of Tusimice II.
Total modernization is no longer necessary
during the power plant's life-cycle.
The Result
■ High plant efficiency is
ensured by a state-of-theart and reliable control
system
■ Utilization of the DCS for
the complete plant lifecycle thanks to the nevergoes-obsolete concept
■ Reliable project execution
thanks to excellent project
management
The Plant
The Tusimice II power plant was initially put into
operation in 1974 by CEZ, a.s. The Czech plant's
ideal location near the heart of the Nastup
Tusimice coal-mining site enables the transport
of needed feed directly into the power plant
using conveyor belts. This ensures that the four
200-MW lignite units are utilized to their full
capacity in order to generate electricity and
district heating for the town of Kadan.
The Task
In order to increase the efficiency of the
power plant and extend its lifetime by 25 years,
the old units dating back to 1974 were to be
completely dismantled and replaced with new
ones. The new sustainable DCS would be
installed in parallel in two of the units, while the
two remaining units would remain in operation.
In addition, the control systems in the auxiliary
systems would be modernized during ongoing
operation. Thus, a reliable partner was needed
who could manage such a complex task.
Our Solution
During modernization of Tusimice II the stateof-the-art and reliable DCS SPPA-T3000 was
installed as the unit control system. The easy-touse system provides plant personnel with
optimal support in operation. In addition the
existing Metso DNA DCS for the auxiliary
systems was modernized, SICAM 1704 was
installed as the switchgear control, and the
power plant building was equipped with
building technologies such as a fire alarm
system, CCTV and an access system. Thanks to
this complete modernization of the control
system, these new components will support
the increased efficiency of the new units and
increase plant availability.
The innovative never-goes-obsolete concept,
which provides hardware-independent
software architecture, will enable future
technical developments to be integrated into
the software, thus ensuring the continued
availability of the DCS throughout Tusimice II's
extended life-cycle.
Additional solutions can be integrated, such as
SPPA-P3000, which enables combustion to be
optimized; or SPPA-M3000, which enables data
to be archived reliably.
The Siemens team ensured that all project
phases were handled reliably, from engineering,
through delivery of components, required
testing, installation and commissioning, right up
to testing of all the control system components
in the power plant.
"Siemens proved itself to
be a strong and competent
partner during the complete
modernization of our power
plant. The new control systems
will also ensure a high
efficiency in the years ahead.“
