WOODWARD CONTROL
WOODWARD 8272-683 DIGITAL REFERENCE UNIT
The 505E controller is
designed to operate
single-extraction
and/or admission
steam turbines of all
sizes and
applications. This
steam turbine
controller includes
specifically designed
algorithms and logic
to start, stop, control,
and protect singleextraction
and/or
admission steam
turbines or turboexpanders,
driving generators, compressors, pumps, or industrial fans. The 505E
control’s unique PID structure makes it ideal for applications where it is required to
control steam plant parameters like turbine speed, turbine load, turbine inlet
pressure, exhaust header pressure, extraction or admission header pressure, or tieline
power.
The control’s special PID-to-PID logic allows stable control during normal turbine
operation and bumpless control mode transfers during plant upsets, minimizing
process over- or undershoot conditions. The 505E controller senses turbine speed
via passive or active speed probes and controls the steam turbine through HP and
LP actuators connected to the turbine steam valves.
The 505E controller senses extraction and or admission pressure via a 4–20 mA
transducer and uses a PID through a ratio/limiter function to accurately control
extraction and/or admission header pressure, while protecting the turbine from
operating outside of its designed operating envelope. The controller uses the specific
turbine’s OEM steam map to calculate its valve-to-valve decoupling algorithms and
the turbine operating and protection limits.
