Abstract
A method for operating a steam turbine plant including a steam turbine and a steam generator allows a power reserve to be provided whilst simultaneously maintaining a high level of efficiency in the normal mode of operation. The steam turbine plant includes a heat reservoir which is associated with the steam turbine, from which the steam is removed and is fed to the steam turbine. The steam is fed to the steam turbine when the steam generator is not in operation.
Claims9
A method for operating a steam turbine plant with a steam turbine and a steam generator, the steam turbine plant comprising a heat store associated with the steam turbine, the method comprising:
- removing steam from the heat store and feeding to the steam turbine,
- wherein the steam is fed to the steam turbine whilst the steam generator is idle, and
- loading the heat store with saturated water from a steam drum of the steam generator whilst a power demand on the steam turbine plant from a power grid is below a preset threshold value.
A steam turbine plant comprising:
- a steam turbine,
- a steam generator,
- a heat store associated with the steam turbine from which steam is removed and fed to the steam turbine, wherein the heat store is adapted such that the steam is fed to the steam turbine whilst the steam generator is idle, and the heat store is loaded with saturated water from a steam drum of the steam generator whilst a power demand on the steam turbine plant from a power grid is below a preset threshold value.
