System and method for operating a steam turbine with digital computer control having setpoint and valve position limiting

Patent ·
OSTI ID:6281857
In a system and method for automatically starting, synchronizing and operating a steam turbine, turbine control including valve position limiting and means for generating a reference control signal representative of desired turbine operation, the reference control signal being limited corresponding to the valve position limit. The reference signal is limited by calculated valve position limits, such that the reference signal is not permitted to rise above such limits. Desired system changes result in reference signal changes which are more quickly reflected in valve position changes, thereby enabling improved system response.
