Definitions

  • the invention relates to a method for controlling a short-term increase in output of a steam turbine with an upstream fossil-fueled continuous steam generator with a number of a flow path forming, flowed through by a flow medium economizer, evaporator and superheater heating, and for example from the US 6301895 B1 known.
  • a fossil-fueled steam generator produces superheated steam using the heat generated by burning fossil fuels.
  • Fossil fueled steam generators are mostly used in steam power plants, which are mainly used for power generation.
  • the generated steam is fed to a steam turbine.
  • the fossil-fueled steam generator also comprises a plurality of pressure stages with different thermal states of the respectively contained water-steam mixture.
  • the flow medium In the first (high) pressure stage, the flow medium first passes through economizers on its flow path, using residual heat to preheat the flow medium, and then various stages of evaporator and superheater heating surfaces.
  • the evaporator the flow medium is evaporated, then separated any residual moisture in a separator and further heated the remaining steam in the superheater. Thereafter, the superheated steam flows into the high-pressure part of the steam turbine, where it is expanded and fed to the following pressure stage of the steam generator. There it is again superheated (reheater) and fed to the next pressure part of the steam turbine.
  • the heat output transferred to the superheaters can fluctuate greatly. Therefore It is often necessary to regulate the overheating temperature. Usually, this is usually achieved by an injection of feedwater before or after individual Matterhitzersammlung inhabit for cooling, ie, an overflow branches off from the main stream of the flow medium and leads to there correspondingly arranged injection coolers. In this case, the injection is usually regulated by means of valves via a characteristic value characteristic of the temperature deviations from a predetermined temperature setpoint at the outlet of the superheater.
  • Modern power plants not only require high levels of efficiency but also the most flexible mode of operation possible. Apart from short start-up times and high load change speeds, this also includes the possibility of compensating for frequency disturbances in the power grid. To meet these requirements, the power plant must be able to provide more power of, for example, 5% and more in relation to full load within a few seconds.
  • Such power changes of a power plant block in the second range are possible only by a coordinated interaction of steam generator and steam turbine.
  • the contribution that the fossil-fueled steam generator can make is the use of its storage, d. H. of the steam but also of the fuel storage, as well as rapid changes of the control variables feedwater, injection water, fuel and air.
  • This additional power can be released in a relatively short time, so that the delayed power increase can be at least partially compensated by the increase in the firing capacity.
  • the entire block makes by this measure immediately a jump in performance and can also permanently maintain or exceed this level of performance by a subsequent increase in the firing capacity, provided that the system was at the time of additionally requested power reserves in the partial load range.
  • This object is achieved according to the invention by increasing the flow of the flow medium through the fossil-fired steam generator for short-term increase in output of the steam turbine.
  • the invention is based on the consideration that the introduced heat output into the steam generator is determined by the firing capacity and only has a comparatively slow effect in the event of a sudden change.
  • An additional benefit payment in the steam turbine should therefore be made by using the heat energy stored in the heating surfaces of the steam generator.
  • the withdrawal of this heat requires a lowering of the average material temperature. This should be done by increasing the flow, i. H. the amount of flow medium flowing through per unit of time can be achieved. Due to the higher flow with comparatively lower medium temperatures, the average material temperature of all heating surfaces is lowered by this measure and as a result thermal energy is released from all these heating surfaces and released in the steam turbine in the form of additional power.
  • the enthalpy desired value at the outlet of an evaporator heating surface is reduced for a short-term increase in output of the steam turbine.
  • the setpoint for the specific enthalpy is used in the control system of the steam generator as a control variable for determining the setpoint for the flow of the flow medium.
  • This switching action has two effects: First, the basic setpoint for the evaporator flow rate calculated in the feedwater setpoint determination increases. Secondly, the enthalpy correction controller - in particular if the reduction takes place particularly quickly (abruptly) - increases its output signal by means of a now greater control deviation in order to reduce the enthalpy at the evaporator outlet as quickly as possible. As a result, the feedwater quantity at the beginning of this measure even increases disproportionately and it is a particularly rapid withdrawal of heat from the heating surfaces with the associated glossentitati in the steam turbine possible.
  • the enthalpy target value is reduced to a predetermined minimum enthalpy value.
  • the Swiss-Shuna is dimensioned such that in all load conditions of the fossil-fired steam generator complete evaporation of the flow medium is achieved in the evaporator heating.
  • the enthalpy at the evaporator outlet is not lowered too far and consequently a seizure of residual water in a downstream separator can be safely avoided.
  • a maximum increase in additional feed water and thus additional performance relief should be achieved with the safest possible driving.
  • the parameters of the measures taken are matched to the required power release in the steam turbine and optimized.
  • the amount and / or duration of the reduction of the enthalpy target value are determined on the basis of the required power increase.
  • flow medium removed in the flow path in the region of a superheater heating surface of the steam generator is injected for short-term increase in output of the steam turbine. Namely, such injections can make a further contribution to the short-term rapid power change.
  • the additional injection in the superheater namely the steam mass flow can be temporarily increased.
  • the stored thermal energy is also used for a temporary increase in power of the steam turbine.
  • the heat input is increased in the fossil-fired steam generator, that is, increases the firing capacity of the burner.
  • a temperature reduction at the evaporator outlet can be favorably influenced or even completely avoided by the described method, since the measure acts as a Vorhaltsignal on the feed water.
  • the method not only allows a short-term increase in performance, but is also used for faster adjustment of a longer-term performance increase.
  • a control system for a fossil-fired steam generator with a number of flow-forming, flowed through by a flow medium economizer, evaporator and superheater heating means comprises means for carrying out the method.
  • a fossil-fired steam generator for a steam power plant comprises such a control system and a steam power plant such a fossil-fired steam generator.
  • the advantages achieved by the invention are, in particular, that by the short-term increase in the amount of feed water, a particularly fast power release in the steam turbine downstream steam turbine is made possible by using the heat energy stored in all heating surfaces.
  • this measure can only be implemented without invasive structural measures with minimal adjustments to the feedwater control concept, so that no additional costs are incurred despite considerably increased system flexibility.
  • the stored thermal energy of the economizer, the evaporator and the first superheater heating surfaces which are located on the flow medium side before the first injection, can be used as additional energy source.
  • a much larger reservoir of stored thermal energy is available for the additionally requested power.
  • either a greater increase in power (peak) can be generated, or an additionally released power can be maintained longer at a lower level.
  • FIG. 1 shows a diagram with simulation results using the control method in a fossil-fired steam generator, ie a sudden reduction of enthalpy target value at the evaporator outlet to increase the feedwater quantity at constant held firing performance.
  • Plotted is the percent additional power in terms of full load 1 versus time 2 in seconds after a sudden reduction in the setpoint of evaporator specific enthalpy by 100 kJ / kg at 95% load. This reduction provides in the control concept for an increase in the feedwater flow rate.
  • Curve 4 shows the result without additional use of injections, while curves 6 and 8 represent the results for additional use of injections in the high-pressure stage or in the high-pressure and medium-pressure stage.
  • curves 10, 12, 14 show the results without increasing the amount of feedwater, but by using only the injections in high-pressure stage (curve 10), medium pressure stage (curve 12) and two pressure levels (curve 14).
  • the injection is achieved by reducing the setpoint for live steam temperature and, if appropriate, reheaction temperature by 20 K.
  • FIG. 2 is opposite FIG. 1 only slightly modified and shows the simulated curves 4, 6, 8, 10, 12, 14 for 40% load, all other parameters coincide FIG. 1 the same applies to the curves 4, 6, 8, 10, 12, 14.
  • the curves 4, 6, 10 show a substantially flatter course than in FIG. 1 that is, there is a slower increase in power at a lower level. Also, the power surplus due to the feedwater flow increase is less pronounced, albeit still significant.
