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
Fault-tolerant I/O handling and processing
- Latent fault detection on relay outputs
- Time-stamped alarms and trips
- Discrete input time-stamp with 1 ms resolution
- Analog input time-stamp with 5 ms resolution
- Extensive fault detection and annunciation—including first-out indication
- Critical speed avoidance (3 speed bands)
- Auto start sequence (hot & cold starts)
- Three sensors per critical parameter can be configured
- Dual speed/load dynamics
- Zero speed detection with proximity probe down to 0.5 Hz
- Peak speed indication for overspeed trip
- Automatic hand valve operation (using first stage pressure)
- Independent Modbus® * communication links
- Remote analog setpoints for all PIDs
- CCT (Configuration & Commissioning Tool)—17” (43 cm) touchscreen engineering workstation for configuration, service, and Turbine operation.
5009FT control functional capabilities:
- Speed/frequency control
- Turbine or generator load control/limiting
- Extraction and/or admission header pressure control
- Compressor control (optional add-on)
- 1 or 2 loop
- Anti-surge protection
- Performance control
- Turbine inlet header pressure control/limiting
- Turbine exhaust header pressure control/limiting
- Plant import/export power control/limiting
- Isochronous load sharing between units (with EGCP-3 controls)
- Any process directly related to unit load
- Proportional or integrating Servo Position Control with LVDT/RVDT excitation (part number dependent)
