    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
