Steam Turbine Control System

Steam Turbine Control System

Increase reliability, reduce maintenance, improve diagnostics and employ more precise control on your steam turbines.

Proven Steam Turbine Control Solutions

For over 50 years and with more than 1,000 installations worldwide, we have experience with both new-build installations and retrofits of all the major OEM steam turbine types.

With complete engineering and design capabilities on mechanical, overspeed, excitation, and governor controls, combined with rotor stress analysis algorithms and Emerson’s advanced procedural integration, a steam turbine can startup and synch automatically in the most expedient, reliable manner with improved ramp rates.
