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
