Definitions

  • the invention relates to the frequency support operation of a gas and steam turbine installation.
  • EP 1 164 254 B1 describes a gas and steam turbine installation having steam bypass lines for peak load coverage, i.e. for auxiliary power at full load.
  • part of the steam generated in the waste heat steam generator is fed via bypass ducts past the turbine inlets and into further inlets, arranged downstream of these turbine inlets, to the turbine parts, whereby the pressure in the waste heat steam generator can be kept substantially constant and the absorption capacity of the steam turbine—and thereby also the power output—can be increased.
  • Embodiments of the invention are accordingly based on the idea of using storage reserves in the waste heat steam generator in order to generate additional steam by abruptly opening the valves.
  • steam is in addition generated and an adequately dimensioned and rapid supply of heat energy should prevent the common dip in the power profile.
  • control power can be provided at partial load and full load.
  • the absorption capacity of the steam turbine can be increased by means of a control wheel 43 , 44 on the high-pressure turbine 25 , and/or on the intermediate-pressure turbine 27 , by opening corresponding valves.
  • FIGS. 2 and 3 show for the power profile in the event of overload introduction for various ratios of fresh steam pressure to introduction pressure in the high- or intermediate-pressure turbine.
  • the horizontal line indicates the value for steady-state operation.
