[0053] 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.

[0054] 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.

[0055] Based on this, the embodiment of the present invention provides a control method for a full-type gas turbine, referring to Figure 1 , Figure 1 The figure is a flow chart of a first embodiment of a control method for a full-type gas turbine according to the present invention.

[0056] In this embodiment, the control method of the full-type gas turbine includes:

[0057] Step S10: Obtain the equipment model, current operating parameters and current continuous operation time of the gas turbine.

[0058] 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.

[0059] In this embodiment, the current operating parameters of the gas turbine include but are not limited to the gas emissions of the gas turbine during operation, the combustion chamber pressure pulsation, the speed of the compressor, the temperature of each area in the combustion chamber, etc., 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. 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.

[0060] The equipment models of the gas turbine include, but are not limited to, various models of gas turbines of brands such as General Electric (GE), Siemens (SIEMENS), and Mitsubishi (MHI), and this embodiment does not impose any specific restrictions on this.

[0061] The current continuous operation time refers to the cumulative operation time of the gas turbine from the last shutdown to the current moment.

[0062] Step S20: querying the target safe operating parameter range of the gas turbine based on the equipment model and the current continuous operation time.

[0063] In the specific implementation, as the gas turbine continues to operate, it is affected by pipeline blockage, component aging, and changes in external environmental parameters, which causes the combustion performance of the gas turbine to decrease, and its corresponding theoretical safe operating parameter range will also change accordingly. By querying the target safe operating parameter range corresponding to the equipment model and continuous operation time in the database, the operating parameters that need to be adjusted subsequently can be determined. The target safe operating parameter range is used to characterize the normal working range of each operating parameter of the gas turbine.

[0064] Step S30: determining the operating parameter to be adjusted according to the current operating parameter and the target safe operating parameter range.

[0065] When the current operating parameter of the gas turbine is not within the target safe operating parameter range, it indicates that the operating parameter needs to be adjusted to improve the operating efficiency of the gas turbine, and the operating parameter is recorded as the operating parameter to be adjusted.

[0066] Step S40: adjusting the operating state of the gas turbine based on the operating parameter to be adjusted until the operating parameter to be adjusted is reduced to within the target safe operating parameter range.

[0067] It can be understood that adjusting the operating state of the gas turbine includes at least one of the following methods:

[0068] controlling the combustion temperature of each zone of the combustion chamber in the gas turbine;

[0069] adjusting a valve opening of at least one fuel inlet in communication with the gas turbine;

[0070] The pressure within the combustion chamber is adjusted.

[0071] 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, lean fuel is homogeneously premixed for combustion to control the combustion temperature and residence time, thereby reducing NOx emissions; or supercharged combustion is achieved through high-frequency or continuous detonation waves, which can improve cycle efficiency. The flow rate of the fuel involved in the combustion can also 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 CO exhaust concentration.

[0072] This embodiment first determines the target safe operating parameters corresponding to different models and continuous operation durations, and then determines the working parameters to be adjusted that do not meet the working requirements based on the current operating parameters of the gas turbine and the target safe operating parameter range, and then adjusts the operating state of the gas turbine to reduce the working parameters to be adjusted to within the target safe operating parameter range, thereby improving the combustion performance of the gas turbine and not being affected by different models of gas turbines, thereby avoiding the technical problem in the prior art that the combustion performance of gas turbines of various models cannot be efficiently controlled.

[0073] 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:

[0074] Step S201: querying the theoretical safe operating parameter range of the gas turbine according to the equipment model.

[0075] Step S202: Determine the current health state of the gas turbine and the attenuation coefficient corresponding to the current health state through a trained health assessment model based on the current continuous operation time.

[0076] Step S203: determining a target safe operating parameter interval according to the theoretical safe operating parameter interval and the attenuation coefficient.

[0077] It should be noted that gas turbines of different equipment models will have a theoretical safe operating parameter range when they leave the factory. However, during actual operation, their actual safe operating parameters will change due to the working environment or equipment aging. If they operate according to the theoretical safe operating parameters, they may exceed the actual safe operating parameter range of the gas turbine, thereby affecting the combustion performance of the gas turbine.

[0078] Therefore, in this embodiment, the current continuous operation time of the gas turbine is calculated through the trained health assessment model, so as to evaluate the current health state of the gas turbine after long-term operation and the attenuation coefficient corresponding to the current health state, so as to correct the theoretical safe working parameter range and reduce the impact of the decline in combustion performance of the gas turbine caused by long-term operation.

[0079] Furthermore, before determining the current health state of the gas turbine and the attenuation coefficient corresponding to the current health state through the trained health assessment model based on the current continuous operation time, the method further includes:

[0080] Obtain historical operating data of gas turbines of the same equipment model;

[0081] Performing data clustering on the historical operation data by using a preset clustering model to obtain multiple data clustering centers;

[0082] Determining a current health state of the gas turbine according to the current continuous operation time and each data cluster center;

[0083] An attenuation coefficient corresponding to the current health state is generated according to the factory setting parameters of the gas turbine and the current health state.

[0084] In a specific implementation, in order to determine the current health status of the gas turbine, this embodiment performs big data analysis on the historical operating data of gas turbines of the same equipment model, thereby realizing a simulation analysis of the current operating status of the gas turbine. In addition, since the gas turbine is regularly inspected and damaged components are replaced during operation, the impact of blockage or component damage on the health status of the gas turbine is reduced.

[0085] The historical operating data of gas turbines of the same equipment model are clustered and analyzed through a clustering model to obtain multiple data clustering centers. The operating data corresponding to these data clustering centers can be regarded as stable operating parameter intervals. According to the stable operating parameters in the data clustering centers corresponding to different operating durations, the actual health status of the gas turbine under the operating duration can be obtained. Finally, the factory setting parameters of the gas turbine are compared with the actual health status to obtain the attenuation coefficient of the gas turbine under different operating durations.

[0086] Furthermore, the historical operation data is clustered by a preset clustering model to obtain multiple data clustering centers, including:

[0087] Setting a plurality of initial cluster centers according to the operating time of the gas turbine;

[0088] Calculating the distances between the historical operation data and the centers of each initial cluster respectively, and obtaining multiple iterative cluster data sets;

[0089] Update the centroid of each iterative clustering cluster data set;

[0090] Iterative clustering is performed based on the updated centroids of each iterative clustering cluster data set;

[0091] When the number of clustering is greater than or equal to the preset number of iterations, multiple data clustering centers are output according to the centroid of the latest iterative clustering cluster data set.

[0092] In this embodiment, the preset clustering model can be an algorithm model that can realize data analysis clustering based on the K-means clustering algorithm, the DBSCAN clustering algorithm, etc. Taking the K-means clustering algorithm as an example, in this embodiment, different operating time intervals are divided to obtain multiple operating time intervals, and the number of operating time intervals is used as the number of initial clustering cluster centers, so as to obtain the operating data of the gas turbine under different operating time intervals and improve the accuracy of subsequent health status judgment.

[0093] Calculating the distance between the historical running data and the centers of each initial cluster cluster may be calculating the Euclidean distance between each data and the centers of the initial cluster clusters, and then allocating the data with a shorter distance to the nearest cluster cluster, and updating the distance between each data and the center of mass by updating the center of mass of each cluster cluster data set, thereby improving the correlation of the data within each cluster cluster, until the number of clustering times is greater than or equal to the preset number of iterations, and then stopping the iteration to obtain multiple aggregated data cluster centers.

[0094] Further, the updating of the centroid of each iterative clustering data set includes:

[0095] Calculate the running data average of each iterative clustering cluster data set;

[0096] The average value of each running data is taken as the centroid of the corresponding iterative clustering cluster data set.

[0097] For each iterative clustering cluster, all the data in the cluster are averaged and the average value is used as the centroid of the new iterative clustering cluster data set.

[0098] In the specific implementation, the algorithm of iterative clustering is:

[0099]

[0100] Among them, J is the algorithm function of iterative clustering, K is the number of clusters, S k refers to the historical data set of the Kth cluster, x (i) refers to the i-th data in the cluster, μ (k) is the kth cluster center.

[0101] Further, determining the current health state of the gas turbine according to the current continuous operation time and each data cluster center includes:

[0102] Calculating the membership parameter between the current continuous running time and each data cluster center;

[0103] Determining a target data cluster center based on the membership parameter;

[0104] Extracting a health status benchmark value of the target data cluster center;

[0105] The current health state of the gas turbine is determined according to the health state reference value.

[0106] The membership function is used to evaluate the changing speed of each parameter in the gas turbine. For a stable data cluster center, its membership parameter is small, so the stable target data cluster center can be determined according to the parameter interval of the membership parameter, and the data corresponding to the centroid in the data cluster center can be extracted as the health status benchmark value.

[0107] This embodiment queries the theoretical safe operating parameter range of the gas turbine according to the equipment model; determines the current health state of the gas turbine and the attenuation coefficient corresponding to the current health state through a trained health assessment model based on the current continuous operation time; determines the target safe operating parameter range according to the theoretical safe operating parameter range and the attenuation coefficient, and corrects the theoretical safe operating parameter range of the gas turbine according to the current continuous operation time of the gas turbine, thereby reducing the impact of equipment aging or blockage on the operating performance of the gas turbine and improving the control effect of the gas turbine.

[0108] This application also provides a control device for a full-type gas turbine, please refer to Figure 3 , the control device of the full-type gas turbine comprises:

[0109] The acquisition module 10 is used to acquire the equipment model, current operating parameters and current continuous operation time of the gas turbine.

[0110] The query module 20 is used to query the target safe operating parameter range of the gas turbine based on the equipment model and the current continuous operation time.

[0111] The determination module 30 is used to determine the operating parameter to be adjusted according to the current operating parameter and the target safe operating parameter range.

[0112] The control module 40 is used to adjust the operating state of the gas turbine based on the operating parameter to be adjusted until the operating parameter to be adjusted is reduced to within the target safe operating parameter range.

[0113] This embodiment first determines the target safe operating parameters corresponding to different models and continuous operation durations, and then determines the working parameters to be adjusted that do not meet the working requirements based on the current operating parameters of the gas turbine and the target safe operating parameter range, and then adjusts the operating state of the gas turbine to reduce the working parameters to be adjusted to within the target safe operating parameter range, thereby improving the combustion performance of the gas turbine and not being affected by different models of gas turbines, thereby avoiding the technical problem in the prior art that the combustion performance of gas turbines of various models cannot be efficiently controlled.
