Vuosaari A: with a new, uniform control
system for more efficient operation and
monitoring
Reference – Siemens Power & Process Automation (SPPA)
Instrumentation, Controls & Electrical
SPPA-T3000 Control System
SPPA-E3000 Complete Electrical Package
SPPA-R3000 Turbine Controls
can all be operated and monitored via one
uniform control system, which means easier
operator control and better availability for the
Vuosaari A power plant.
The Result
■ Higher availability and
efficiency thanks to
a modern control and
electrical system including
the appropriate service
package
■ Easier consistent operation
and monitoring thanks to
the communication
between the electrical
system and the control
system via IEC 61850
■ Comprehensive plant
automation thanks to
the integration of the
MAN steam turbine into
SPPA-R3000 Turbine Controls
The Plant
The combined cycle power plant, Vuosaari A, was
commissioned in 1991 in Helsinki by Helsingin
Energia, one of the largest energy companies
in Finland. Vuosaari A has two Siemens V64.3
gas turbines, at 58 MW each, and a MAN steam
turbine, at 45 MW. Together with Vuosaari B,
the power plant produces the majority of
electricity and district heat in Helsinki.
The Task
As the power plant was constructed in the 1990s,
some components had reached the end of their
lifetime and spare parts were no longer available.
Additionally, control systems of several manufacturers were in use, which meant that the
operating staff had to work with different HMIs.
By modernizing the power plant with a single
control system that is able to communicate with
the new electrical systems and the turbine control,
Vuosaari A will have a uniform monitoring and
operation system. This new system will also
support the high availability of the CCPP.
Our Solution
The modernization project at Vuosaari A comprises
the state-of-the-art SPPA-T3000 Control System,
including migration from existing Teleperm ME,
several components from the SPPA-E3000
Complete Electrical Package product range and
SPPA-R3000 Turbine Controls. These modern,
comprehensive turnkey solutions, including
a service package, support the high efficiency
and availability of the power plant. By using
SPPA-T3000 as the control system for Vuosaari A,
an all-encompassing concept was realized.
All electrical components were fully integrated
via IEC 61850 in the unit control. This was the
first project in which this communication
protocol was used in Finland.
The turbine control of the two Siemens gas
turbines and the MAN steam turbine were
modernized with SPPA-R3000. Additionally,
the hydraulic interface of the steam turbine
was adapted to the new turbine control system.
In addition to the electrical systems, SPPA-R3000
is also integrated in the hardware, engineering
and the HMI of the modern control system.
The result is a uniform control system for all
automation tasks. All components can be
monitored and operated via a single user
interface from the control room and from
several work stations in the power plant. This
makes these tasks much easier for operators
and supports the high availability and efficiency
of Vuosaari A.
The competence of a turnkey supplier, as well
as the experience and know-how of the project
team, contributed towards the first class
execution of this project.

“Today we operate our turbines,
electrical components and
basically the whole power plant
with one single control system.
This makes our work not just
easier, but also much more
efficient.”
