Definitions

  • the invention relates to a power plant with a steam generator and a steam turbine according to the preamble of claim 1 and a method for operating a power plant according to the preamble of claim 5.
  • Power plants usually include a steam generator and a steam turbine, which are designed such that the internal energy of a water vapor is converted into mechanical rotational energy.
  • the generators driven by such steam turbines are usually operated at 50 Hz for the European market and 60 Hz for the US market.
  • Modern steam turbines are exposed to a water vapor, which may have a pressure of up to 350 bar and a temperature of up to 700 ° C.
  • This steam needed in the steam turbine is generated in the steam generator, which presents a challenge to the materials and components of the steam generator.
  • Particularly important components are power control, pressure control and speed control. In order to be able to operate the required 50 Hz or 60 Hz constant over a longer required period of time, high demands are placed on the controls.
  • Power plants are usually required for base load operation, which means that the entire system is constantly stressed over a longer period of time.
  • the frequency of the steam turbine shaft and the amount of steam leading to the steam turbine is substantially constant.
  • the generator applied torque transmission changes, which means that the performance of the steam turbine could suddenly change, which should be prevented by the scheme.
  • a sudden change in the power of the steam turbine is also given by a possible fault.
  • a power plant is operated in the fixed pressure, sliding pressure or power mode.
  • the steam turbine has to transmit a lower torque to the generator. This could be accomplished by closing the valves arranged for delivery to the steam turbine or by providing the steam generator with a lower amount of steam at a lower pressure.
  • the pressure controls are designed such that a live steam pressure is brought in a high-pressure steam system during startup of the steam turbine to a fixed pressure value.
  • a diversion line is arranged such that the high-pressure steam inlet of the steam turbine is fluidly connected to the high-pressure steam outlet of the steam turbine.
  • the invention begins, whose task is to further develop a power plant such that a power loss is further reduced.
  • the invention proposes to arrange an overload line, which forms a fluidic connection between the steam generator and an overload stage of the steam turbine, and to arrange a arranged in the overload line overload control valve that is controlled by a pressure regulator.
  • the advantage of the invention is u.a.
  • the overload line acts as a sort of diverter station, thereby directing the steam into the steam turbine rather than uselessly bypassing the steam turbine.
  • the steam turbine is designed such that the overload stage, which is fluidically connected to the overload line, is designed such that the inflowing steam is converted work-giving.
  • the overload stage which is fluidically connected to the overload line
  • the inflowing steam is converted work-giving.
  • An essential feature of the method according to the invention is that the pressure regulator, which controls the overload control valve, is designed such that a desired value can be set and the bypass control valve only opens when the desired value is exceeded, when the overload control valve is already open is.
  • the overload control valve opens at partial load and / or full load.
  • the power plant can be operated more flexible overall, since both the power regulator and in the pre-pressure operation, the overload control valve can be controlled at each power. Another advantage is that the start-up and power losses are lower because the overload control valve directs the steam into the steam turbine rather than uselessly past the steam turbine into the condenser.
  • the power plant 1 comprises a steam turbine 2, which comprises a high-pressure turbine section 2a, a medium-pressure turbine section 2b and a low-pressure turbine section 2c. Via a steam generator 3, live steam passes via a live steam line 4 via a live steam control valve 5 into a high pressure steam inlet 6 of the high pressure turbine part 2a.
  • the power plant 1 comprises a bypass line 7, the main steam line 4 with a high-pressure steam outlet 8 of the high-pressure turbine section 2a fluidly connects. In the bypass 7, a bypass control valve 9 is arranged.
  • the power plant 1 comprises an overload line 10, which connects the steam generator 3 with an overload stage 11 of the high-pressure turbine part 2a fluidly.
  • an overload control valve 12 is arranged in the overload line 10.
  • the overload control valve 12 and the bypass control valve 9 are closed, the live steam control valve 5 is open and is controlled by a pressure regulator or power controller, not shown.
  • the effluent from the high-pressure turbine section 2a steam is referred to as a cold reheater steam and reheated in a reheater 13.
  • the effluent from the reheater 13 steam is referred to as hot superheated steam 14.
  • This hot superheated steam 14 flows through a medium-pressure control valve 15 in the medium-pressure turbine section 2b and is converted there relaxes work.
  • the steam flowing out of the medium-pressure turbine section 2b is fluidically connected via medium-pressure discharge lines 16 to the low-pressure steam inlet 17 of the low-pressure turbine section 2c.
  • the effluent from the low-pressure turbine section 2c steam is passed through a low-pressure discharge line 18 to a condenser 19, where it is converted to water and finally fed via a feedwater pump 20 to the steam generator 3, whereby a steam cycle is closed.
  • the vapor converted from thermal energy to rotational energy drives a shaft 21, which in turn drives a generator 22 which eventually provides electrical energy.
  • the main steam control valve 5, the overload control valve 12 and the bypass control valve 9 are also each arranged on its own separate pressure regulator.
  • the responsible for the overload control valve 12 pressure regulator is such designed that a setpoint is adjustable and the overload control valve 12 opens when exceeding this setpoint before the bypass control valve 9 opens.
  • the overload control valve 12 is usually opened at full load.
  • the steam flowing in via the overload stage 11 is converted into a work-giving function, instead of being uselessly guided past the high-pressure turbine section 2 a via the bypass line 7.
  • the efficiency of the power plant is further increased thereby.
  • a new pressure characteristic for the overload control valve 12 is set between a sliding pressure characteristic of the high-pressure turbine section 2a and the high-pressure bypass characteristic curve.
  • the overload control valve 12 opens and not the bypass control valve 9.
  • the overload control valve 12 then regulates a predetermined by the new pressure characteristic pressure.
  • the live steam is used via the overload control valve 12 in the high-pressure turbine section 2a and not useless passed to the steam turbine 2 in the condenser 19.
  • FIG. 2 shows pressure curves as a function of the steam mass flow.
  • the live steam pressure 26 is plotted on the Y axis and the steam generator mass flow 25 is plotted on the X axis.
  • the sliding pressure characteristic 27 represents the usual course of operation. When the turbine valves are fully opened, the steam mass flow rates are fully absorbed by the turbine at the rated pressure.
  • the nominal value characteristic curve 28 of the bypass station runs at a pressure difference ⁇ P above the sliding pressure characteristic curve 27. This has the consequence that the bypass station is not opened too early. Only when the operating pressure has increased by the pressure difference, the bypass valves are opened.
  • an additional characteristic 29 for the overload valve control is included between the sliding pressure characteristic curve 27 and the nominal value characteristic curve 28.
  • the additional characteristic curve 29 is above the sliding pressure characteristic curve 27 and below the nominal value characteristic curve 28.
