SPPA-R3000 Turbine Controls
is the perfect modernization solution with
comprehensive automation functions for gas
and steam turbines from any vendor.
Your Benefits
■ Increased availability and
lifetime
■ Increased operational
reliability
■ Increased flexibility
■ Reduced maintenance costs
The Task
In addition to expensive spare parts
warehousing, increasing failure probability
affecting the mechanical and electrical
components utilized to control and protect
Alstom gas turbines results in decreasing
availability and deteriorating operational
reliability.
The main turbine and generator components
still retain a high residual lifetime. The old
control and protection systems are no longer
up to the task of meeting today's requirements
for cost-effective operation of the turbosets.
Our Solution
SPPA-R3000 offers concepts that are adapted
to the specific requirements of BBC/ABB/Alstom
gas turbines of types GT 9, 11, and 13 and have
proven their worth over and over in operation.
In addition to the control system, the
modernization solution can also include
vibration monitoring and analysis, electrical
engineering, modernization of the hydraulic
system, and field instrumentation.
The basis is the globally leading SPPA-T3000
control system that forms the platform for
automation, control and protection. It is
employed for turbines, auxiliary systems
and the main control system and permits
seamless integration of all functional areas
of the plant. Thanks to its scalability, it can be
used not only as a stand-alone turbine solution
but also for modernization of the entire plant
with a uniform operating and engineering
environment.
Our service portfolio comprises everything from
feasibility studies to the realization of basic
functionalities for Alstom gas turbines,
fail-safe protection with SIL3 certification,
installation/commissioning, and complete
documentation.
Modernization can help to eliminate systembased failures of the legacy system as well as
performance losses that were previously caused
by aging effects on the field and control
devices.
Replacement of the mechanical overspeed
protection with electronic protection (SIL3certified), eliminating the real run-up to the
overspeed value, protects the turbine.
In case of a fault, automated expert alarming
using a paging system, along with remote
diagnostic capability for maintenance
personnel, ensures reduced downtimes.
The bus connection of the electrical systems to
the main control system via IEC 61850 ensures
faster diagnostics all the way to the field level.
The higher degree of automation also facilitates
operations, eliminating the need for manual
intervention. Improved mapping of the plant
processes and elimination of former interface
problems reduce the overall plant start-up time
and avoid turbine emergency shut-offs.
Modernization by replacing the legacy systems
with Siemens technology takes place during
planned turbine overhaul without
causing additional downtime.
SPPA-R3000 increases the availability of BBC/Alstom gas
turbines – e. g. in Kriel Power Station, South Africa.
