Abstract: A method for the short-term adjustment of the output of a steam turbine of a combined-cycle power plant, includes: opening, respectively closing, a backed-up turbine valve of a pressure stage, according to a required change in output; comparing a desired pressure with a pressure measurement upstream of the turbine valve to measure pressure of steam mass flow flowing into the pressure stage; and opening, respectively closing, a feed line for introducing a variable proportion of water into the steam mass flow as soon as the pressure falls below or exceeds the desired pressure; the variable proportion of water is introduced into the steam mass flow until an adjusted desired steam temperature is reached, which is determined from the difference between a basic specified desired steam temperature and the default value of a controller which operates at least proportionally and evaluates the difference between the pressure measurement and the desired pressure.

Abstract: A solar thermal power plant including a solar collector steam generator unit for generating steam, a solar collector steam superheater unit for superheating the steam, and a steam turbine is provided. The solar thermal power plant includes an intermediate storage which is connected to the steam conduit system in a first high-temperature storage connecting point interposed between the solar thermal steam superheater unit and the steam turbine to remove steam superheated in a storage mode from the steam conduit and which includes a heat reservoir in which thermal energy is drained from the steam fed into during the storage mode and is accumulated and the stored thermal energy is given off to the steam in an extraction mode, steam being fed to the steam conduit system from the intermediate storage. The intermediate storage is connected to a condenser and/or a relaxation device of the plant in a low-temperature storage connecting point.
