Regulating system for steam turbine, has interconnection unit interconnecting individual regulators on regulating switching unit whose target-actual-difference between maximum selection unit and minimum selection unit is selected

摘要

The system has a regulating selection unit (20) exhibiting a maximum selection unit (20.1) for selecting a maximum value from two target-actual-differences that are multiplied with proportional reinforcements. A minimum selection unit (20.2) selects a minimum value from two target-actual-differences that are multiplied with proportional reinforcements. An interconnection unit (20.3) interconnects individual regulators (10.1-10.4) on a regulating switching unit (30) whose target-actual-difference between the maximum selection unit and the minimum selection unit is selected. An independent claim is also included for a regulating method for regulating a steam turbine with a monitoring system.
