  • Method for the primary control in a combined gas/steam turbine installation
    Patent number: 6912855
    Abstract: The aim of the invention is to improve a method for the primary control so that reserve power that is practically completely available for the effective frequency boost within seconds is available also in the stem turbine part of a gas/steam turbine installation. To this end, the pressure stage is operated with a control valve (6, 7, 8) that is throttled to such an extent that a frequency boost power reserve is built up. Said power reserve is used for frequency boosting in the event of an underfrequency by correcting the desired value depending on the underfrequency. Said corrected value corresponds to an effective area of the flow that is increased vis-รข-vis the throttled condition of the control valve (6, 7, 8) and acts on the effective area of flow of the control value (6, 7, 8) with an impressed signal that approaches zero after a predetermined time.
