Abstract (en)
[origin: WO2006037417A1] The invention relates to a method and module for a predicted start-up of steam turbines in a turbine plant, by means of a module (1), whereby optimised time curves for the steam parameters at the entrance to the turbine and at the boiler exit are determined before and/or during the turbine start-up with regard to the permitted stress of the critical points of the metal of the turbine by means of a forecast module (10) integrated in the module (1). The stress on the critical points of the metal of the turbine is regulated to an optimally rising stress set value until the attainment of a permitted stress limit by means of the forecast model (10). The permitted stress is maintained under control by the forecast model (10) until the nominal steam temperature is reached, whereby the applied set parameters for the boiler and/or turbine control are the opening speed of the fresh steam control valve (Y<SB>HD</SB>) and the relief control valve (Y<SB>MD</SB>) and on reaching the maximum setting for the valves the speed of change of the steam parameter at the relevant turbine entrance is used as set parameter.
