Woodward

Woodward released its popular 505 steam turbine controller in 1985 which now has become the industry standard in steam turbine control. The standard off-the-shelf controller was purposely - built for small - to medium-size steam turbines driving generators, pumps or compressors.

The latest 505 controller models contain many new features that improve reliability and performance including:

• Integrated full color HMI for complete turbine visibility
• OptiTune “auto-tuning” PID for optimum performance
• Generator load rejection anticipation logic
• Three critical speed avoidance bands
• Auto-start routines based on turbine temperature
• Compressor “Performance Control” de-coupling logic
• Plant boiler loss protection control
• Dual-Redundant capability (2 Master/Slave based 505’s)

Woodward designs its line of steam turbine control products to be easily integrated together,simplifying system design and assuring unit-to-unit compatibility. This integrated approach reduces installation costs and allows customers to scale their system components to meet the requirements of small, medium, or large steam turbine applications.
