Abstract
Method for controlling steam admission into a steam turbine, the turbine comprising a high pressure casing, at least one reduced pressure casing and an admission steam control system, the high pressure casing and at least one reduced pressure casing comprising control valves for steam admission. The admission steam control system manages the following steps: determining a steam flow demand; elaborating a high pressure control valve opening setpoint depending on the determined steam flow demand; imposing the elaborated high pressure control valve opening setpoint to the high pressure control valves; elaborating a reduced pressure control valve opening setpoint depending on the determined steam flow demand through the dynamic interaction between high pressure control valve opening setpoint and reduced pressure control valve opening setpoint; and imposing the elaborated reduced pressure control valve opening setpoint to the reduced pressure control valves.
