[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] Based on this, an embodiment of the present invention provides an automatic fuel adjustment method for a gas turbine, referring to Figure 1 , Figure 1 The figure is a flow chart of a first embodiment of an automatic fuel adjustment method for a gas turbine according to the present invention.

[0047] In this embodiment, the automatic fuel adjustment method of the gas turbine includes:

[0048] Step S10: Acquire the current operating parameters of the gas turbine.

[0049] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a control computer electrically connected to a gas turbine, etc. The following takes a control computer electrically connected to a gas turbine as an example to illustrate this embodiment and the following embodiments.

[0050] It should be noted that in the field of heavy-duty gas turbine operation and maintenance, the automatic fuel adjustment technology used by foreign heavy-duty gas turbine equipment manufacturers for gas turbines is mainly to automatically adjust the flow of on-duty fuel through a preset combustion adjustment curve. For example, the automatic fuel adjustment technology used by Siemens is the above-mentioned solution. The American GE manufacturer uses real-time feedback of combustion state parameters through a thermodynamic cycle model to automatically and continuously distribute and adjust the fuel. However, its thermodynamic cycle model is also pre-set, the same as the above-mentioned combustion adjustment curve, and is suitable for specific working conditions. However, the working conditions faced by gas turbines during operation are complex and changeable, and the current automatic fuel adjustment technology cannot meet the user's usage needs.

[0051] In this embodiment, the current operating parameters of the gas turbine include but are not limited to the gas emissions and combustion chamber pressure pulsation of the gas turbine during operation, wherein the gas emissions include but are not limited to various NO xGas and CO, etc. A large amount of polluting gases will be emitted during the operation of the gas turbine. Excessive polluting gases will cause environmental pollution and incomplete combustion will occur. The combustion residue will affect the service life of the equipment. The combustion chamber pressure pulsation data will affect the normal operation of the gas turbine. Too low combustion chamber pressure may cause the gas turbine to stall. Frequent shutdown and restart will seriously damage the service life of the equipment.

[0052] Furthermore, after obtaining the current operating parameters of the gas turbine, the method further includes:

[0053] The current working parameters are preprocessed, and the preprocessing at least includes: moving arithmetic average, exponentially weighted moving average and extreme value processing.

[0054] Since it is difficult to collect the working parameters of the gas turbine during operation, especially the emission of pollutant gases, it is difficult to directly use them for subsequent combustion adjustment judgment and single adjustment step calculation. For example, when obtaining the pressure pulsation data of the combustion chamber, a combustion chamber pressure probe or a high-speed pressure sensor or other device can be used for collection. In order to improve the accuracy of the combustion chamber pressure pulsation data, arithmetic averaging can be performed on multiple collected pressure pulsation data to improve the accuracy of the pressure pulsation data within a time period. When collecting the emission of pollutant gases, a continuous emission monitoring system (CEMS) can be used, which can be used to monitor and record the concentration and emission of pollutants emitted by industrial emissions in real time, or a risk evaluation and mitigation strategy system (REMS). Other devices or equipment that can realize gas emission collection can also be used. This embodiment does not impose specific restrictions on this.

[0055] Step S20: Determine whether to perform combustion adjustment according to the current working parameters.

[0056] For the above-mentioned pollutant gas emissions, the lower the better. However, for the combustion chamber pressure pulsation data, it is best to process a reasonable parameter range to avoid damage to the equipment due to excessive or insufficient pressure.

[0057] When judging whether the gas turbine needs combustion adjustment, it can be determined by comparing the range of the current working parameters. Different gas turbines and different current environmental emission standards will also directly affect the range of the corresponding preset safe working parameter range. For example: for type A gas turbine, when its NOx exhaust concentration is greater than 35 mg / m3, it is judged that combustion adjustment is required; and for type B gas turbine, when the NOx exhaust concentration is greater than 9 ppm, it is judged that combustion adjustment is required. This embodiment does not impose specific restrictions on this.

[0058] Step S30: If yes, determine a single adjustment step length according to the current working parameters.

[0059] It should be noted that, since the combustion curve or thermodynamic cycle model is used for adjustment in the above text, the operating state of the gas turbine may change significantly, which may cause the gas turbine to shut down or vibrate significantly, affecting the normal operation of the equipment. In this embodiment, the automatic fuel adjustment is divided into multiple steps. After each adjustment, the next step of adjustment can be carried out after the gas turbine is stabilized.

[0060] The operating state of the gas turbine will be affected by the proportions of various fuels or air involved in the combustion in the combustion chamber. Therefore, in this embodiment, the optimal single adjustment step corresponding to the valves of the fuel inlets of various fuels is determined to reduce the possibility of equipment stalling or large vibrations during the subsequent automatic fuel adjustment process.

[0061] Step S40: Based on the single adjustment step size and the automatic fuel adjustment strategy, the valve opening of at least one fuel inlet in the gas turbine is adjusted at least once until the current operating parameter is reduced to within a preset safe operating parameter range.

[0062] It can be understood that the automatic fuel adjustment strategy means that by first increasing the valve opening of at least one fuel inlet and detecting the working parameters of the gas turbine, if the working parameters of the gas turbine are close to the preset safe working parameter range, the valve opening is continued to be increased according to the single adjustment step; if the working parameters of the gas turbine are far from the preset safe working parameter range, the valve opening is reduced according to the single adjustment step;

[0063] Or first reduce the valve opening of at least one fuel inlet and detect the operating parameters of the gas turbine. If the operating parameters of the gas turbine are close to the preset safe operating parameter range, continue to reduce the valve opening according to a single adjustment step. If the operating parameters of the gas turbine are far from the preset safe operating parameter range, increase the valve opening according to a single adjustment step.

[0064] The above adjustment strategy is also called trial-and-error adjustment, that is, when the adjustment direction is uncertain, adjustment is made in one direction (increase or decrease). If the operating parameters of the gas turbine do not meet the adjustment conditions after the adjustment, adjustment is made in the opposite direction.

[0065] Furthermore, the automatic fuel adjustment method for the gas turbine further comprises:

[0066] Recording the current operating parameters, target operating parameters and the adjustment scheme of the gas turbine;

[0067] The current operating parameters, the target operating parameters and the adjustment scheme of the gas turbine are stored correspondingly.

[0068] In the specific implementation, after the adjustment, the corresponding adjustment value is recorded and stored in the storage medium according to the current operating point. When the engine runs to the operating point again, the adjustment value will be directly called, thereby reducing the trial and error adjustment steps and improving the adjustment efficiency.

[0069] This embodiment collects the operating parameters of the gas turbine during operation to determine whether it is necessary to interfere with the combustion process of the gas turbine. When it is determined that combustion adjustment is required, a single adjustment step is determined according to the current operating parameters of the gas turbine. Finally, a valve opening of at least one fuel inlet in the gas turbine is adjusted according to a predetermined automatic fuel adjustment strategy, thereby reducing the operating parameters of the gas turbine to within a preset safe operating parameter range, improving the combustion performance of the gas turbine during operation, and avoiding the technical problem in the prior art that the combustion performance of the gas turbine fluctuates, resulting in excessive pollutant emissions from the gas turbine.

[0070] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S40:

[0071] Step S401: adjusting the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the first adjustment direction.

[0072] Step S402: Obtain the adjusted target operating parameters of the gas turbine.

[0073] Step S403: When the target operating parameter does not meet the preset condition, the valve opening of at least one fuel inlet in the gas turbine is adjusted based on the single adjustment step and the second adjustment direction, and the first adjustment direction is opposite to the second adjustment direction.

[0074] It should be noted that the reference Figure 3 , Figure 3 This is a schematic diagram of an example of the mapping relationship between the adjusted parameters and the adjustable parameters in this embodiment. If the first adjustment direction refers to increasing the valve opening of at least one fuel inlet in the gas turbine, the second adjustment direction is to reduce the valve opening of the corresponding fuel inlet in the gas turbine; if the first adjustment direction refers to reducing the valve opening of at least one fuel inlet in the gas turbine, the second adjustment direction is to increase the valve opening of the corresponding fuel inlet in the gas turbine.

[0075] The preset condition means that the adjusted working parameter is close to the preset safe working parameter range corresponding to the working parameter. For example, the current exhaust concentration of NOx is 35mg / m3, and the corresponding preset safe working parameter range is less than 10mg / m3. When the valve opening of the gas is increased, the NOx concentration of the adjusted gas turbine is 40mg / m3, which means that the adjustment is invalid and the valve opening of the gas needs to be reduced to improve the combustion efficiency of the gas turbine.

[0076] Furthermore, before adjusting the valve opening of at least one fuel inlet of the gas turbine based on the single adjustment step and the second adjustment direction, the method further includes:

[0077] The valve opening of each fuel inlet is restored to the opening corresponding to the current operating parameter.

[0078] After determining that the adjustment is invalid, since there may be a situation where multiple valve openings are adjusted simultaneously, in order to reduce the trial and error cost and shorten the adjustment time, this embodiment can restore the valve opening of each fuel inlet to the opening corresponding to the current operating parameter before adjusting in the opposite direction, which will not affect the normal operation of the gas turbine and can save time for automatic fuel adjustment.

[0079] In a specific implementation, during a single fuel adjustment process, multiple fuel inlet valves in the gas turbine may be adjusted. In order to improve the efficiency of automatic fuel adjustment and the combustion performance of the gas turbine, this embodiment encloses the parameters to be adjusted into an adjustment window. Figure 4 , Figure 4 By continuously adjusting the opening of each valve in the adjustment window, the optimal combustion condition of the gas turbine is determined to obtain the lowest combustion exhaust volume and the appropriate combustion chamber pressure.

[0080] Furthermore, the automatic fuel adjustment method for the gas turbine further comprises:

[0081] When the target operating parameter meets the preset conditions, return to the step of adjusting the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the first adjustment direction until the target operating parameter is reduced to within the preset safe operating parameter range.

[0082] As mentioned above, if the current exhaust concentration of NOx is 35mg / m3, the corresponding preset safe operating parameter range is less than 10mg / m3. After the air valve opening is increased, the NOx concentration of the adjusted gas turbine is 20mg / m3, which means that the adjustment is effective and the air valve opening can be continued to increase to further reduce the NOx concentration and improve the combustion efficiency of the gas turbine until the exhaust concentration of NOx is less than 10mg / m3, and stop increasing the air valve opening.

[0083] Further, when the target operating parameter meets the preset condition, returning to the step of adjusting the valve opening of at least one fuel inlet of the gas turbine based on the single adjustment step and the first adjustment direction comprises:

[0084] Obtaining the change value of the working parameter of the gas turbine;

[0085] When the operating parameter change value meets the preset conditions and the operating parameter change value is greater than the preset change value, return to the step of adjusting the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the first adjustment direction until the target operating parameter is reduced to within the preset safe operating parameter range.

[0086] It is understandable that even if the adjusted operating parameters of the gas turbine are close to the preset safe operating parameter range of the corresponding parameters, there may be a small change in the operating parameters, that is, the operating parameters have little effect on the overall combustion conditions of the gas turbine, which will also be regarded as an invalid adjustment and the fuel inlet valve to be adjusted needs to be replaced. For example: if the current exhaust concentration of NOx is 35mg / m3, and the corresponding preset safe operating parameter range is less than 10mg / m3, when the air valve opening is increased, the NOx concentration of the gas turbine after adjustment is 34mg / m3, which means that the adjustment is invalid, which may be due to insufficient fuel causing combustion problems. Therefore, the NOx concentration can be further reduced and the combustion efficiency of the gas turbine can be improved by trial and error adjustment of the gas valve opening, that is, first restore the air valve opening, and increase the valve opening of any gas, observe the NOx concentration. If the NOx concentration of the gas turbine after adjustment is 40mg / m3, it means that the adjustment is invalid, and change the adjustment direction. If the NOx concentration of the gas turbine after adjustment is 20mg / m3, it means that the adjustment is effective, and the gas valve opening can be continued to increase to further reduce the NOx concentration and improve the combustion efficiency of the gas turbine until the exhaust concentration of NOx is less than 10mg / m3, and stop increasing the air valve opening.

[0087] This embodiment adjusts the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the first adjustment direction; obtains the target operating parameters of the gas turbine after adjustment; when the target operating parameters do not meet the preset conditions, adjusts the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the second adjustment direction, and the first adjustment direction is opposite to the second adjustment direction. The gas turbine is adjusted in a small trial-and-error manner by a single adjustment step, so as to improve its combustion performance, reduce pollutant gas emissions or increase combustion chamber pressure pulsation without determining the combustion conditions of the gas turbine combustion chamber, adapt to the complex conditions in the actual combustion process, and improve the operating efficiency of the gas turbine.

[0088] The present application also provides an automatic fuel adjustment device for a gas turbine, please refer to Figure 5 , the automatic fuel adjustment device of the gas turbine comprises:

[0089] The acquisition module 10 is used to acquire the current operating parameters of the gas turbine.

[0091] The determination module 30 is configured to determine a single adjustment step size according to the current operating parameters if yes.

[0092] The fuel adjustment module 40 is used to adjust the valve opening of at least one fuel inlet in the gas turbine at least once based on the single adjustment step and the automatic fuel adjustment strategy until the current operating parameter is reduced to within a preset safe operating parameter range.

[0093] This embodiment collects the operating parameters of the gas turbine during operation to determine whether it is necessary to interfere with the combustion process of the gas turbine. When it is determined that combustion adjustment is required, a single adjustment step is determined according to the current operating parameters of the gas turbine. Finally, a valve opening of at least one fuel inlet in the gas turbine is adjusted according to a predetermined automatic fuel adjustment strategy, thereby reducing the operating parameters of the gas turbine to within a preset safe operating parameter range, improving the combustion performance of the gas turbine during operation, and avoiding the technical problem in the prior art that the combustion performance of the gas turbine fluctuates, resulting in excessive pollutant emissions from the gas turbine.

[0095] In one embodiment, the fuel adjustment module 40 is further used to return to the step of adjusting the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the first adjustment direction when the target operating parameter meets the preset conditions, until the target operating parameter is reduced to within the preset safe operating parameter range.

[0096] In one embodiment, the fuel adjustment module 40 is also used to obtain the change value of the operating parameter of the gas turbine; when the change value of the operating parameter meets the preset conditions and the change value of the operating parameter is greater than the preset change value, it returns to execute the step of adjusting the valve opening of at least one fuel inlet in the gas turbine based on the single adjustment step and the first adjustment direction until the target operating parameter is reduced to within the preset safe operating parameter range.
