[0047] 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.

[0048] 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.

[0049] Based on this, an embodiment of the present invention provides a control method for a gas turbine, referring to Figure 1 , Figure 1 The figure is a flow chart of a first embodiment of a gas turbine control method according to the present invention.

[0050] In this embodiment, the gas turbine control method includes:

[0051] Step S10: Acquire the working parameter set of the gas turbine in real time.

[0052] 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.

[0053] The working parameter set of the gas turbine includes the current working parameters and the historical working parameters, wherein the working 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 NOx gases and CO, etc. A large amount of polluting gases will be emitted during the operation of the gas turbine, and excessive polluting gases will cause environmental pollution, and incomplete combustion will occur. The combustion residue will subsequently affect the service life of the equipment, and 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, and frequent shutdown and restart will seriously damage the service life of the equipment.

[0054] Furthermore, after the real-time acquisition of the gas turbine operating parameter set, the method further includes:

[0055] The working parameter set is preprocessed, and the preprocessing at least includes: moving arithmetic average, exponentially weighted moving average and extreme value processing.

[0056] 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 it 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 and other devices can be used for collection. In order to improve the accuracy of the combustion chamber pressure pulsation data, the arithmetic average of multiple collected pressure pulsation data can be performed 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 to monitor and record the concentration and emission of industrial pollutants 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.

[0057] Step S20: predicting the operating parameters to be adjusted of the gas turbine through the trained neural network model based on the operating parameter set.

[0058] It should be understood that the trained neural network model in this embodiment is used to predict the operating parameters of the gas turbine in the next cycle that may exceed the preset safe operating parameter range, so that the operating parameters in the next cycle that may exceed the preset safe operating parameter range can be intervened in advance to avoid fluctuations in combustion performance of the gas turbine in the next cycle.

[0059] Step S30: determining the adjustment priority of each working parameter to be adjusted.

[0060] The working parameters to be adjusted refer to working parameters that partially exceed the corresponding preset safe working parameter range and working parameters that may exceed the preset safe working parameter range in the next cycle predicted by the trained neural network model. Different gas turbines and current environmental emission standards will directly affect the range of the corresponding preset safe working parameter range. A priority will be pre-set between different working parameters. In this embodiment, the priorities of pressure pulsation parameters, NOx exhaust concentration and CO exhaust concentration decrease in sequence.

[0061] Step S40: adjusting the operating state of the gas turbine based on the adjustment priority and the operating parameter to be adjusted until the operating parameter to be adjusted is reduced to within a preset safe operating parameter range.

[0062] It should be noted that the control of the gas turbine in this embodiment is different for different operating parameters to be adjusted, because in different environments, adjusting a certain operating parameter of the gas turbine may cause changes in another operating parameter. For example, flue gas circulation technology can be used to reduce the generation of NOx, but it may lead to increased CO emissions and poor low-load stability.

[0063] By setting the priority between various working parameters, working parameters with higher priorities can be adjusted first, thereby improving the working efficiency of the gas turbine and increasing the production capacity. For example: when the working parameters to be adjusted are pressure pulsation parameters and NOx exhaust concentration, since the pressure pulse parameters will directly affect the working efficiency of the gas turbine, under normal load conditions, the larger the pressure pulse parameters are within the preset safe working parameter range, the higher the working efficiency of the gas turbine and the better the combustion performance. Therefore, the pressure pulse parameters can be adjusted first. Even if the pressure pulse parameters do not exceed the preset safe working parameter range in the current cycle, the pressure pulse parameters will be predictively adjusted to avoid the pressure pulse parameter range exceeding the preset safe working parameter range in the next cycle.

[0064] This embodiment obtains the working parameter set of the gas turbine in real time; predicts the working parameters to be adjusted of the gas turbine through a trained neural network model based on the working parameter set; determines the adjustment priority of each working parameter to be adjusted; adjusts the operating state of the gas turbine based on the adjustment priority and the working parameter to be adjusted until the working parameter to be adjusted is reduced to within a preset safe working parameter range, predicts the working parameters to be adjusted of the gas turbine through a trained neural network model, and then adjusts the operating state of the gas turbine based on the adjustment priority of each working parameter to be adjusted, thereby achieving pre-intervention of the combustion performance of the gas turbine, improving the combustion performance of the gas turbine, and avoiding the technical problem in the prior art that the combustion performance of the gas turbine fluctuates and causes excessive pollutant emissions from the gas turbine.

[0065] 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 S20, comprising:

[0066] Step S201: dividing the acquired operating parameters of the gas turbine to obtain a first operating parameter outside a preset safe operating parameter range and a second operating parameter within the preset safe operating parameter range.

[0067] Step S202: determining a target operating parameter through a trained neural network model based on the second operating parameter.

[0068] Step S203: determining the operating parameter to be adjusted of the gas turbine according to the first operating parameter and the target operating parameter.

[0069] It should be noted that when dividing the working parameters of the gas turbine, the various working parameters of the current cycle can be compared with their corresponding preset safe working parameter ranges to determine whether the various working parameters in the current cycle are within the corresponding preset safe working parameter ranges, and those outside the preset safe working parameter ranges are recorded as first working parameters, and those within the preset safe working parameter ranges are recorded as second working parameters.

[0070] The target operating parameters are those that are within the preset safe operating parameter range, but are judged by the trained neural network model to have a risk of exceeding the boundary of the preset safe operating parameter range. For example, the local environmental protection standard requires that the NOx exhaust concentration should not exceed 35mg / m 3 , then when the NOx exhaust concentration of the gas turbine is 34mg / m 3 When the NOx exhaust concentration is within the preset safe working parameter range, the trained neural network model combined with the historical change trend of the NOx exhaust concentration determines that the NOx exhaust concentration has a risk of exceeding the preset safe working parameter range, that is, exceeding 35mg / m3. In this case, the NOx exhaust concentration can be recorded as the target working parameter.

[0071] The trained neural network model may be a recurrent neural network (RNN). In this embodiment, the trained neural network model includes an input layer, a hidden layer, and an output layer. In this embodiment, the hidden layer state is:

[0072] ht=σ(W hh *h t-1 +W ih *x t +b h )h t =σ(W hh *ht-1+W ih *x t +b h )

[0073] The output layer status is:

[0074] yt=W ho *h t +b o

[0075] Among them, h t is the hidden state of the current time step, W hh is the weight matrix from hidden layer to hidden layer, which represents the recursive connection inside the hidden layer, Wih is the weight matrix from the input layer to the hidden layer, which represents the influence of the input on the hidden state, σ is the activation function, xt is the current input, and yt is the current output.

[0076] Further, determining the target operating parameter through a trained neural network model based on the second operating parameter includes:

[0077] Performing data preprocessing on the second working parameter, wherein the data preprocessing at least includes moving arithmetic average, exponentially weighted moving average, extreme value processing, elimination of abnormal data, and smoothing processing;

[0078] The trained neural network model is used to perform an out-of-bounds prediction on the second working parameter after data preprocessing to obtain a target working parameter, where the target working parameter is a second working parameter that has a risk of exceeding a corresponding preset working parameter interval.

[0079] In a specific implementation, 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 it 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 pollutant gas emissions, a continuous emission monitoring system (CEMS) can be used, which can be used to monitor and record the concentration and emission of industrial pollutants in real time, or a risk assessment 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.

[0080] Furthermore, the performing of an over-boundary prediction on the second working parameter after data preprocessing by using the trained neural network model includes:

[0081] Acquiring a historical change trend of the second operating parameter and an equipment parameter of the gas turbine;

[0082] Predicting the working parameters of the next adjustment cycle through the trained neural network model according to the historical change trend and the preprocessed second working parameters;

[0083] Calculating the confidence of the working parameters of the next adjustment cycle according to the equipment parameters;

[0084] According to the confidence level, it is detected whether the working parameter of the next adjustment cycle exceeds the corresponding preset safe working parameter range.

[0085] The historical change trend of the second working parameter refers to the data change trend of the second working parameter within the historical adjustment period, as well as the change trend of the working parameters of the same type of gas turbines under similar operating conditions. If the confidence of the predicted working parameters for the next adjustment period is greater than the set confidence threshold, it can be determined that the working parameters for the next adjustment period are credible and can be directly used for the determination of the target working parameters. If the confidence of the predicted working parameters for the next adjustment period is less than the set confidence threshold, it can be re-predicted.

[0086] This embodiment divides the acquired working parameters of the gas turbine to obtain a first working parameter within a preset safe working parameter range and a second working parameter outside the preset safe working parameter range; determines a target working parameter based on the second working parameter through a trained neural network model; determines the working parameter to be adjusted of the gas turbine according to the first working parameter and the target working parameter, and interferes with the combustion efficiency of the gas turbine in the next cycle in advance by taking the working parameters that have exceeded the boundary and the working parameters that are about to exceed the boundary as the working parameters to be adjusted, so as to improve the working efficiency of the gas turbine in the next cycle.

[0087] 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 3 , step S40, comprising:

[0088] Step S401: When the priority of the first operating parameter is greater than the target operating parameter, the operating state of the gas turbine is adjusted to reduce the first operating parameter to a corresponding preset safe operating parameter range.

[0089] Step S402: When the priority of the first operating parameter is less than or equal to the target operating parameter, the operating state of the gas turbine is adjusted to reduce the target operating parameter to a corresponding preset safe operating parameter range.

[0090] It should be noted that when adjusting the operating state of the gas turbine based on the working parameters to be adjusted, the working parameters with higher priority can be adjusted first. Even if the working parameters with higher priority do not exceed the corresponding preset safety working parameter boundaries, they can be adjusted first, thereby improving the combustion performance of the gas turbine in the next cycle.

[0091] The priority setting is related to the degree of influence of various operating parameters on the combustion performance of the gas turbine. For example, the pressure pulsation data of the combustion chamber has a greater impact on the combustion performance, and the priority setting is higher. Specifically, in this embodiment, the priorities of the pressure pulsation parameters, NOx exhaust concentration, and CO exhaust concentration decrease in sequence.

[0092] Further, the adjusting the operating state of the gas turbine includes at least one of the following methods:

[0093] controlling the combustion temperature of each zone of the combustion chamber in the gas turbine;

[0094] adjusting a valve opening of at least one fuel inlet in communication with the gas turbine;

[0095] The pressure within the combustion chamber is adjusted.

[0096] In a specific implementation, controlling the combustion temperature of each area of ​​the combustion chamber in the gas turbine can reduce the generation of thermal NOx. For example, the combustion temperature and residence time can be controlled by homogeneous premixing of lean fuel to achieve the purpose of reducing NOx emissions; or supercharged combustion can be achieved through high-frequency or continuous detonation waves to improve cycle efficiency, and the flow rate of the fuel involved in the combustion can be adjusted to control the fuel content in the combustion chamber, thereby controlling the combustion chamber to be in a suitable combustion condition and reducing the CO exhaust concentration.

[0097] In this embodiment, when the priority of the first operating parameter is greater than the target operating parameter, the operating state of the gas turbine is adjusted to reduce the first operating parameter to a corresponding preset safe operating parameter range; when the priority of the first operating parameter is less than or equal to the target operating parameter, the operating state of the gas turbine is adjusted to reduce the target operating parameter to a corresponding preset safe operating parameter range, thereby giving priority to adjusting the parameters to be adjusted with higher priorities, preventing more serious combustion performance degradation of the gas turbine in the next cycle, and improving combustion efficiency.

[0098] The present application also provides a control device for a gas turbine, please refer to Figure 4 , the control device of the gas turbine comprises:

[0102] The adjustment module 40 is used to adjust the operating state of the gas turbine based on the adjustment priority and the operating parameter to be adjusted until the operating parameter to be adjusted is reduced to within a preset safe operating parameter range.
