Definitions
- the invention relates to a method for rapid Power control of a steam power plant with a one Steam turbine and a generator set comprising a generator. she further relates to one for performing the method suitable steam power plant.
- the set point for the temperature of the flowing out of the superheater heating surface Steam reduced by a predetermined amount. How it turns out that the steam temperature drops the superheater heating surface due to the increased injection rate of the water after about 60 s, which is a temperature-controlled Regulation to reduce the injection rate of the Water and thus to a decrease in from the steam turbine performance. With a timely Lowering the setpoint for the temperature of the superheater heating surface escaping steam this is safely avoided.
- the advantages achieved with the invention are in particular in that the setting of a generator extra power by increasing the rate of water injection with special simple means and without additional requirements to the components used.
- the concept for fast power control is suitable is particularly suitable for steam turbines of normal design, which in the entire load range with a particularly low Heat consumption can be operated.
- the steam turbine will with such a fast power control in only a small amount Dimensions claimed so that repeated repetition such a rapid power control for no damage leads to the steam turbine.
- the steam power plant 1 comprises a steam turbine 2, via a turbine shaft 4 with a generator 6 connected is.
- the steam turbine comprises 2 a high pressure part 2a and a low pressure part 2b.
- the Steam turbine 2 is thus carried out in two stages.
- the steam turbine 2 also only one or more, in particular include three pressure levels.
- the evaporator heating surface 32 is also in the steam generator 28 arranged high pressure superheater 34 connected, the output side to the steam inlet 36 of the high pressure part 2a of the steam turbine 2 is connected.
- the steam outlet 38 of the high pressure part 2a of the steam turbine 2 is via a reheater 40 to the steam inlet 42 of the low pressure part 2b of the steam turbine 2 connected.
- Its steam outlet 44 is connected to the condenser 12 via the steam line 10, so that a closed water-steam circuit 46 is formed.
- the water-steam circuit 46 shown in the figure is thus built up from only two pressure stages. But he can also from only one or from several, in particular three Pressure stages can be built up, in the steam generator 28 in a known manner Way further heating surfaces are arranged.
- Both the high pressure part 2a and the low pressure part 2b of the steam turbine 2 are each one with a valve 48 or 50 lockable bypass line 52 or 54 can be bypassed.
- the bypass line associated with the low pressure part 2b of the steam turbine 2 54 opens directly into the outlet the capacitor 12.
- the steam power plant 1 has a fast power control guaranteed with particularly simple means. A generator extra power is doing this by increasing the Water W injection rate into the high pressure superheater 34 and / or in the reheater 40 possible.
