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 ().

Control system for matching the output of a steam turbine to a changed load

An electrolytic power plant using an electrolysis device which requires one part of the electric energy which is produced by the power plant. The electrolysis device forms a variable load for the constant control network frequency and produces hydrogen and oxygen. The power plant has an oxygen pump, a buffer container, an oxygen distribution line, and an oxygen pump that are used for the accumulated oxygen.

The invention relates to a method and a device for supporting the frequency in an electricity network () during a sudden modification of the network load and/or generating power. According to the invention, modifications of the network load and/or generating power, which cause the network frequency to deviate from a predefined value, are compensated by a modification of an additional load (). Said additional load () is preferably configured by a large number of hydrogen-producing electrolysis units (), which can be activated or deactivated for the successive modification of the additional load.
