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. The redundant high availability system allows for online maintenance, diagnostics, and automatic testing. The HMI system features an easy to use graphical interface for all plant personnel including operators and maintenance. Comprehensive mechanical modernization packages are available to be integrated with the SPPA-R3000 system.
The SPPA-R3000 system can be used in both power and industrial applications. Standard applications include:
■ Single, double and triple extraction ■ Inlet and admission ■ Exhaust and condensing ■ Mechanical drives
Stop Valve conversion Before After

Control Features
Various mechanical upgrades can be implemented with the control upgrades or added later on.
Control Features
■ Full range of turbine startups from manual to automatic
■ Primary overspeed protection ■ High speed valve lift control ■ First trip out indication ■ Speed control ■ Load control ■ Inlet/Admission pressure control ■ Extraction pressure/temperature
control ■ Frequency Influence (Droop Control) ■ ADS (Automatic Dispatch System)
influence ■ Turbine stress influence ■ Options available:
■ Independent overspeed protection ■ Simplex or redundant
configurations ■ Remote control station ■ Turbine auxiliary control ■ Generator auxiliary control ■ Generator excitation control ■ Turbine Stress Control (TSC) ■ 24-hour remote on-line support
Operator Display
The easy to use SPPA-R3000 HMI displays have several available options. The local display panels provide information and local control. The remote server client option offers both operator control and engineering functions to be done remotely. The remote server client is also available in a redundant server configuration which can accept multiple client computers for multiple users.
■ Full MHC to EHC turbine conversion ■ Removal of mechanical overspeed
bolt and replace with electronic, on-line testable, backup overspeed protection system
■ Replacement of existing legacy TSI system with new state of the art electronic TSI system
■ Replacement of simplex field devices with redundant field devices
■ Valve replacement / upgrades ■ Replacement of existing legacy trip
system with new redundant, on line testable trip system
