Abstract
The invention relates to a control system for matching the output of a steam turbine () to a changed load, in particular for the short-term matching of the output of a power plant steam turbine () to changed network loads within the context of primary control. The control system according to the invention is characterized by a heat store () which, when there is an increased volume of steam tapped off from the steam turbine () under a correspondingly reduced load, extracts heat from the steam and which, when there is a reduced quantity of steam tapped off from the steam turbine under a correspondingly increased load, gives up heat to a steam/feed water circuit supplying the steam turbine ().
