SPPA-R3000 for Power and
Industrial Steam Turbines
Standard solutions
Siemens Energy Instrumentation,
Controls & Electrical has implemented an
innovative solution for modernizing
steam turbines that can be integrated
into a customer’s current or future plant
system using a scalable, standard, proven
platform. Upgrading to our SPPA-R3000
turbine control solution can help you
generate true long-term benefits for
operations, maintenance and service of
your steam turbines. The SPPA-R3000 is a
cost-effective, high-performance,
modular solution that can provide
enhancement in system reliability and
capability. The SPPA-R3000 can be
implemented at low-cost based upon the
plant’s configuration and the customer’s
requirement.
The redundant system is designed to
increase availability and minimize costly
downtime. It also allows for on-line
maintenance, diagnostics and automatic
testing. The HMI system features an easy
to use graphical interface for all plant
personnel, including operators and
maintenance workers. Comprehensive
mechanical modernization packages are
available for integration with the
SPPA-R3000 system.
The SPPA-R3000 system can be used in
both power and industrial applications.
