Abstract

A method is provided for primary control of a steam turbine installation in network operation, which provides at least two pressure stages, these being a high-pressure and a low-pressure steam turbine stage, in which for storing reserve power a live steam valve along an operating-steam feed line to at least one pressure stage of the steam turbine is operated in a throttled manner, the live steam valve, in the case of a reducing network frequency and network frequency boosting which is necessary as a result of this, is transferred to an at least less throttled state. At least some of the partially expanded operating steam which issues from the high-pressure steam turbine stage is introduced directly without reheating, into the low-pressure steam turbine stage for further expansion.
