Definitions
- the invention relates to the use of an electrical Spei memory, in particular an accumulator for faster start-up of a steam turbine.
- the steam turbine is kept at a certain, low warm-up speed, in the electrically disconnected state, whereby no current can be fed into the electrical network because the speed is too low.
- This heating through at the warming-up speed is achieved by the steam flowing through, which is required and generated to keep the steam turbine at the warming-up speed.
- the low-pressure part is usually not heated at all because the low-pressure valves are still closed due to the low steam requirement.
- the waiting time until the steam turbine is sufficiently heated and can be accelerated further can take up to 8 hours. Excess generated steam is discharged via the steam diversion station and deposited in the condenser unused.
- An electrical storage device such as, in particular, an electrical accumulator, loads a generator in the charging mode and thus a turbine coupled to it, such as a steam turbine in particular.
- the higher amount of steam is preferably taken from the unused deposited energy and preferably not generated additionally.
- a turbine or turbines such as, in particular, a steam turbine or a steam turbine set can take up to 1.5 hours to stop.
- the generator is disconnected from the grid and connected to the accumulator.
- This leakage energy is converted into electrical energy by the generator and charged into the accumulator.
- the shaft train is thus braked faster and the critical speed ranges run faster.
- the level of the heating speed is as usual in the state of the art.
- the generator is switched on as described above, so that heating can take place quickly before the generator is connected to the grid.
- the figure shows schematically an installation 1 according to the invention.
- Steam turbine or (steam) turbine generator is considered equivalent in the following, as are the terms: battery, electrical storage, accumulator, ...
- An exemplary power generation system 1 is shown in the figure.
- the energy generation plant 1 comprises at least one steam turbine 7, which has at least one, in particular only one, generator 10 for generating electricity 19.
- the electricity 19 is passed on to end users via electrical networks 20.
- the generator 10 can be removed from the electrical network 20 when the steam turbine 7 is shut down.
- the generator 10 is preferably not connected to the electrical network 20 when it is started, that is to say when it is warmed through.
- a gas turbine 4 can also be present, which is coupled to the steam turbine 7 and generator 10 in a combined cycle process.
- the gas turbine 4 is less time-critical than the steam turbine 7 during a quick start.
- the main feature is the presence of an electrical storage device 13.
- the electrical storage device 13 is charged by the generator 10 when the steam turbine 7 or steam turbine turbine set is running down via a line 16 and / or when the heating speed is maintained and when the steam turbine 7 is started up.
- the line 16 can optionally be connected to the generator 10 by means of a switch 17.
- the electrical energy stored in the memory 13 can be used in turn via lines 25 to one or more To operate networks 20 or it is used internally for the system ver (via line 23).
- a "boiler” or nuclear reactor can also be used as a heat source for the steam, so it is not limited to gas turbines.
