  • An important feature of medium-load power plants is the start time, ie the time until a defined system performance is available.
  • a short start time is advantageous, among other things, because it allows the possibility of participating in balancing markets such as the minute or hour reserve.
  • a participating in the minute reserve power plant must be able to bring a few minutes (in Germany, for example, after 15 minutes) a certain power.
  • the performance is to be provided after 60 minutes.
  • Start-up times and standstill times occur after the components have been heated or cooled, whereby the warm-up or cool-down is usually influenced by the temperature surrounding the components (natural cooling).
  • transient plant conditions such states are to be understood here, in which a power plant of a power level to another, such as when driving on ⁇ , is transferred. There is therefore a need to keep the transient states as short as possible. Also at

  • the object related to the method is achieved according to the invention by specifying a method for controlling a power plant with a plurality of components forming an operating cycle, namely with a boiler, a steam turbine and optionally a gas turbine, wherein at standstill the component temperature of at least one component of a the components is controlled by heat exchange by means of a fluid flow.
  • the invention is based on the consideration that the heat present in the power plant after switching off the components can be used to specifically regulate the component temperature of the components of the components at standstill.
  • components of the components or the operating cycle here are the individual components or groups of components that are functionally connected to each other and a unit bil ⁇ den called.
  • a fluid flow is used, which transports the heat from one component or component of the power plant ⁇ to another component or other component, so that at standstill active at least one of the components is maintained at a desired temperature level.
  • Standstill here is the period of time in which the power plant is in the retracted state, with a rotor of the power plant can be rotated at low speed or can stand completely still.
  • the main advantage of this method is that with an active control of the temperature of the components or some of their components, the stopping or the starting of the components is no longer dependent on the currently prevailing - not actively influenced - component temperatures. Rather, these component temperatures are adjusted by active heat exchange at standstill, as far as possible, the appropriate operational requirements for improved shutdown or start-up behavior of the power plant.
  • the heat exchange is performed by means of an additional control circuit for the fluid flow.
  • the control ⁇ circulation differs from the operating circuit of the power plant and is characterized by separate lines and control elements. A separate circuit from the operating circuit is particularly easy to control.

  • the method may be used to control the power station component to a Kom ⁇ cooling when at least one further component is at a lower temperature level and can absorb the heat of the hotter component. This is done by a suitable control of the flow direction of the fluid flow, the latter removes the heat of the hotter Kom ⁇ component and discharges this heat into the colder component. It is sufficient if only two components of the power plant, which are located at different temperature levels, are connected to the control circuit.

  • the component to be serviced or repaired must cool down to ambient temperature in order for the work to be carried out.

  • a particularly efficient heat transfer in which the on ⁇ wall for cooling or heating of the components is particularly low, is given, if preferably the components are heated or cooled independently of each other.
  • the aim here is to keep the components of the components at a homogeneous temperature level.
  • the rotor and the housing of the gas turbine are maintained at about the same temperature level, ie the housing must be kept warm by the active temperature control, since the housing usually cools off faster ⁇ .
  • heat is tapped only from certain areas of the components: For example, after switching off the power plant, only those in the high- pressure part of the steam turbine existing heat can be used to maintain a relatively high Tempera ⁇ turn level of the gas turbine at standstill of the power plant.
  • the heat exchange between the components is carried out by means of a water vapor.
  • Water vapor has a number of advantages when used as a heat-carrying fluid stream: water is inexpensive, environmentally friendly ⁇ and easy to handle.
