5009FT Triple Modular Redundant (TMR) Fault Tolerant Steam Turbine Control

Woodward’s 5009FT TMR controls industrial steam turbines of all sizes and types in system-critical applications requiring maximum reliability and availability. This steam turbine controller includes specifically-designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turbo-expanders, driving compressors, generators, or pumps.

Designed for today's plant standardization practices, the 5009FT control system's versatile program can be configured to control steam turbines that are:

single valve
single extraction
single admission
single extraction/admission

The 5009FT control's unique PID structure makes it ideal for petrochemical or power generation applications where it is required to control steam plant parameters like:

compressor speed
generator frequency
turbine load
turbine inlet pressures
exhaust header pressures
tie-line power
