Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of gas turbines, and particularly to an ignition control method, a readable medium, and a pure hydrogen gas turbine for a pure hydrogen gas turbine. Background Art

[0002] Pure hydrogen gas turbines are mostly used for power grid peak shaving and need to be started and stopped frequently. Ignition is one of the most critical steps in the startup process of a pure hydrogen gas turbine unit. To meet the requirements of power load scheduling, a high success rate of the first ignition of the gas turbine is required. Currently, when performing an ignition operation on a gas turbine, the commonly used method is: only some combustion chambers perform ignition operations, and the remaining combustion chambers are ignited through a flame tube, and a flame detector is used to determine whether the ignition is successful.

[0003] However, the inventors found that when using the above method to perform an ignition operation on a pure hydrogen gas turbine, there are often the following technical problems: the fuel of the pure hydrogen gas turbine is pure hydrogen, and the flame propagation speed of hydrogen is relatively fast. When igniting through a flame tube, when the flame propagation in the flame tube gets out of control, the risk of deflagration or flashback is relatively high, resulting in relatively low safety during the ignition process.

[0009] In a third aspect, some embodiments of the present disclosure provide a computer-readable medium storing a computer program thereon, where the computer program, when executed by a processor, implements the method described in any implementation manner of the first aspect.

[0010] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: The ignition control method applicable to a pure hydrogen gas turbine according to some embodiments of the present disclosure can improve the safety of the ignition operation of the pure hydrogen gas turbine. Specifically, the number of times that the pure hydrogen gas turbine fails to ignite during actual operation and causes the unit to trip is relatively large, and the reason for the low safety is as follows: Ignition is achieved through a flame tube. When the flame propagation in the flame tube gets out of control, the risk of deflagration or flashback is relatively high, resulting in low safety during the ignition process. Based on this, the ignition control method applicable to a pure hydrogen gas turbine according to some embodiments of the present disclosure is applied to a pure hydrogen gas turbine. First, in response to receiving the ignition start information, control the purging device included in the above-mentioned pure hydrogen gas turbine to perform a purging operation. Among them, the above-mentioned pure hydrogen gas turbine further includes a motor, a combustion device, and a fuel supply device. The above-mentioned combustion device includes each combustion chamber, and each combustion chamber included in each of the above-mentioned combustion chambers is provided with an igniter and a combustion chamber thermocouple. The above-mentioned fuel supply device includes a hydrogen supply pipeline assembly, and the above-mentioned hydrogen supply pipeline assembly includes a first fuel control valve, a second fuel cut-off valve, and a third fuel cut-off valve. Thus, each pipeline in the pure hydrogen gas turbine and the interior of the gas turbine can be purged, thereby cleaning the impurities and air existing in the pipeline and the interior of the gas turbine, and further preventing ignition failure and explosion. Second, in response to detecting the purging completion information, control each igniter included in the above-mentioned pure hydrogen gas turbine to perform an ignition operation, and control the above-mentioned first fuel control valve, the above-mentioned second fuel cut-off valve, and the above-mentioned third fuel cut-off valve to perform an opening operation according to the preset first ignition opening information. Thus, ignition operations can be performed on each combustion chamber included in the pure hydrogen gas turbine simultaneously. After that, in response to determining that the current time meets the preset ignition duration condition, control the above-mentioned first fuel control valve to perform an opening reduction operation according to the preset second ignition opening information. Thus, the opening of the fuel valve can be adjusted to the opening for normal ignition. Then, in response to determining that the current time meets the preset ignition waiting duration condition, obtain the temperature monitoring information sequence set corresponding to each combustion chamber thermocouple included in the above-mentioned pure hydrogen gas turbine and the valve state information of the above-mentioned first fuel control valve. Thus, the temperature information and fuel supply information of the combustion chamber can be obtained, which can be used to determine whether the ignition is successful. Immediately afterwards, generate ignition result information according to the above-mentioned temperature monitoring information sequence set and the above-mentioned valve state information. Thus, it can be determined whether the ignition is successful. Finally, in response to determining that the above-mentioned ignition result information meets the preset ignition success condition, control the above-mentioned first fuel control valve to perform an opening holding operation. Thus, when the pure hydrogen gas turbine ignites successfully, the normal operation of the pure hydrogen gas turbine is maintained. Also, because during the ignition operation of the pure hydrogen gas turbine, each igniter performs ignition operations on each combustion chamber simultaneously, without the need for a flame tube to transfer flame, the safety and success rate of the ignition operation can be improved. Thus, the safety of the ignition operation of the pure hydrogen gas turbine can be improved. Brief Description of the Drawings

[0021] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0022] Figure 1 Flow 100 of some embodiments of an ignition control method applicable to a pure hydrogen gas turbine according to the present disclosure is shown. The ignition control method applicable to a pure hydrogen gas turbine, which is applied to a pure hydrogen gas turbine, includes the following steps:

[0023] Step 101, in response to receiving ignition start information, controlling a purging device included in the pure hydrogen gas turbine to perform a purging operation.

[0024] In some embodiments, the execution subject (e.g., pure hydrogen gas turbine) of the ignition control method for a pure hydrogen gas turbine can control the purge device included in the above-mentioned pure hydrogen gas turbine to perform a purge operation in response to receiving the ignition start information. Among them, the above-mentioned ignition start information can indicate the start of the ignition operation of the pure hydrogen gas turbine. For example, the above-mentioned ignition start information can be "start". The above-mentioned pure hydrogen gas turbine can be: a gas turbine whose fuel is 100% hydrogen. The above-mentioned pure hydrogen gas turbine can include but is not limited to a motor, a purge device, a combustion device, and a fuel supply device. The above-mentioned purge device can be a device for purging the various pipelines included in the pure hydrogen gas turbine and the inside of the pure hydrogen gas turbine. The above-mentioned combustion device can be a device for mixing hydrogen with air for combustion. The above-mentioned fuel supply device can be a device for supplying hydrogen and air. The above-mentioned pure hydrogen gas turbine can also include an axial flow compressor, a turbine rotor, and a cooling device. The above-mentioned axial flow compressor can be used to inhale and compress air in the atmosphere to provide high-pressure air for the combustion chamber. The axial compressor and the turbine rotor can be connected by flanges and supported by two support bearings. The cooling device can be a device for transporting water, air or other cooling media to the parts that need cooling, and taking away the heat generated by high-temperature components such as turbines and combustion chambers through circulating flow to prevent overheating of the components. The combustion device can include but is not limited to each combustion chamber. The number of each combustion chamber can be 10. The combustion chamber can be a chamber for mixing and burning hydrogen and air. Each combustion chamber included in each combustion chamber can be provided with an igniter and a combustion chamber thermocouple. The igniter can be used for ignition. The combustion chamber thermocouple can be a thermocouple for monitoring the wall temperature at the outlet of the combustion chamber nozzle. Two thermocouples can be provided at the nozzle of each combustion chamber. The fuel supply device can include but is not limited to a hydrogen storage device and a hydrogen supply pipeline assembly. The hydrogen supply pipeline assembly can include but is not limited to a fuel pipeline, a first fuel control valve, a second fuel shut-off valve and a third fuel shut-off valve. The first fuel control valve can be a control valve for controlling the flow rate of the supplied hydrogen. The second fuel shutoff valve may be arranged in front of the first fuel control valve. The third fuel shutoff valve may be arranged behind the first fuel control valve and located at the end of the fuel pipeline. The second fuel shutoff valve may be used to control whether hydrogen is supplied to the fuel pipeline. The third fuel shutoff valve may be used to control whether fuel is passed into each combustion chamber. The purge operation may be an operation of purging each pipeline included in the pure hydrogen gas turbine and the inside of the pure hydrogen gas turbine.

[0025] In the process of adopting technical solutions to solve the technical problems in the background technology, there is often another technical problem as follows: Hydrogen molecules are relatively small and have a relatively fast diffusion rate, making it easier to penetrate into the fuel pipeline. Under the action of the pipeline pressure, it is likely to permeate into the fuel pipeline and accumulate in the metal lattice defects in atomic form, resulting in a reduction in the toughness of the fuel pipeline, and thus leading to cracks in the fuel pipeline and fuel leakage. In response to the above technical problem 2, the conventional solution is generally to regularly detect cracks in the fuel pipeline. However, the above conventional solution still has the following problems: During the operation of a pure hydrogen gas turbine, fuel is continuously transported. Only by regularly detecting cracks in the fuel pipeline, when relatively large cracks are detected, hydrogen leakage has already occurred, resulting in relatively low safety during the operation of the pure hydrogen gas turbine.

[0026] Considering the problems of the above conventional solution, in the face of the above technical problem 2, in cooperation with artificial intelligence researchers in universities, and combining the artificial intelligence algorithms they possess, the following solution can be adopted:

[0027] Optionally, before the above execution subject controls the purging device to perform the purging operation, the above execution subject can also perform the following steps:

[0028] In the first step, for each fuel branch pipeline included in the above respective fuel branch pipelines, the following sub-steps are performed:

[0029] In the first sub-step, crack detection processing is performed on the above fuel branch pipeline to obtain crack monitoring information. Among them, the above crack monitoring information can characterize whether there are cracks inside the corresponding fuel branch pipeline and the size and location of the cracks. The above crack monitoring information can include but is not limited to crack size and crack location. In practice, the above execution subject can perform crack detection processing on the above fuel branch pipeline through a preset crack detection algorithm to obtain crack monitoring information. The above preset crack monitoring algorithm can be an algorithm for detecting cracks in metal pipelines. For example, the above preset crack monitoring algorithm can be a pulse modulation eddy current detection method.

[0030] The second sub-step is to obtain the historical crack prediction information sequence and the historical crack monitoring information sequence corresponding to each historical time point. Among them, the historical crack prediction information sequence can be a sequence in which each historical crack prediction information is arranged in ascending order of time. Each historical crack prediction information corresponds to a historical time point. The historical crack prediction information can characterize the crack information at the corresponding historical time point. The above historical crack prediction information can include, but is not limited to, the historical crack prediction size and the historical crack prediction position. The above historical crack prediction size can be the crack size at the predicted historical time point. The above historical crack prediction position can be the crack position at the predicted historical time point. The above crack position can be represented by cylindrical coordinates. The historical crack monitoring information sequence can be a sequence in which each historical crack monitoring information is arranged in ascending order of time. Each historical crack monitoring information corresponds to a historical time point. The historical crack monitoring information can characterize the crack information monitored at the corresponding historical time point. The historical crack monitoring information can include, but is not limited to, the historical crack monitoring size and the historical crack monitoring position. The above historical crack monitoring size can be the crack size at the monitored historical time point. The above historical crack monitoring position can be the crack position at the monitored historical time point. In practice, the above execution subject can obtain the historical crack prediction information sequence and the historical crack monitoring information sequence corresponding to each historical time point from the database through wired connection or wireless connection.

[0031] The third sub-step is to generate crack deviation prediction information according to the above historical crack prediction information sequence and the above historical crack monitoring information sequence. Among them, the above crack deviation prediction information can characterize the predicted crack deviation information. The above crack deviation information can characterize the deviation between the predicted crack and the actually monitored crack. In practice, first, for each historical crack prediction information included in the above historical crack prediction information sequence, the above execution subject can perform the following steps:

[0032] Sub-step one, determine the historical crack monitoring information corresponding to the above historical crack prediction information in the above historical crack monitoring information sequence as the target crack monitoring information. Among them, the historical crack monitoring information corresponding to the above historical crack prediction information is the historical crack monitoring information with the same historical time point as the historical time point corresponding to the above historical crack prediction information.

[0033] Sub-step two, determine the difference between the historical crack monitoring size included in the above target crack monitoring information and the historical crack prediction size included in the above historical crack prediction information as the crack size deviation.

[0034] Sub-step three, determine the coordinate deviation between the historical crack monitoring position included in the above target crack monitoring information and the historical crack prediction position included in the above historical crack prediction information as the crack position deviation.

[0035] Sub-step 4: Combine the above crack size deviation and the above crack position deviation to obtain crack prediction deviation information.

[0036] Then, sort the obtained crack prediction deviation information in the order of the above historical crack prediction information sequence to obtain a crack prediction deviation information sequence.

[0037] After that, input the above crack prediction deviation information sequence into a pre-trained crack deviation prediction information generation model to obtain crack deviation prediction information. Among them, the above crack deviation prediction information generation model can be a time series prediction model that takes the crack prediction deviation information sequence as the input and the crack deviation prediction information as the output. The above crack deviation prediction information can be the crack deviation information at a predicted future time point. The above crack deviation prediction information can include, but is not limited to, crack size prediction deviation and crack position prediction deviation. The above time series prediction model can be a long short-term memory network (LSTM).

[0038] Fourth sub-step: Add the above crack monitoring information to the above historical crack monitoring information sequence to obtain an updated historical crack monitoring information sequence.

[0039] Fifth sub-step: Input the above updated historical crack monitoring information sequence into a pre-trained first crack prediction information generation model to obtain first crack prediction information. Among them, the above first crack prediction information generation model can be a time series prediction model that takes the updated historical crack monitoring information sequence as the input and the first crack prediction information as the output. The above first crack prediction information can be the crack information at a predicted future time point. The above first crack prediction information can include a first crack prediction size and a first crack prediction position. The above first crack prediction size can be the size of the crack at a predicted future time point. The above first crack prediction position can be the position of the crack at a predicted future time point.

[0040] Sixth sub-step: Generate second crack prediction information according to the above first crack prediction information and the above crack deviation prediction information. In practice, first, the above execution entity can determine the sum of the first crack prediction size included in the above first crack prediction information and the crack size prediction deviation included in the above crack deviation prediction information as the second crack prediction size. Then, determine the sum of the first crack prediction position included in the above first crack prediction information and the crack position prediction deviation included in the above crack deviation prediction information as the second crack prediction position. Finally, determine the above second crack prediction size and the above second crack prediction position as the second crack prediction information.

[0041] Second step, in response to determining that each of the generated second crack prediction information satisfies the preset safe crack condition, control the above-mentioned purging device to perform a purging operation. Among them, the above-mentioned preset safe crack condition may be that the second crack prediction size included in the second crack prediction information is less than the preset safe crack size. The above-mentioned preset safe crack size may be a size of a crack that is preset and fixedly characterized as not affecting the safety during the operation of a pure hydrogen gas turbine.

[0042] The above technical solution and its related content are an inventive point of an embodiment of the present disclosure, which solves the technical problem of "low safety during the operation of a pure hydrogen gas turbine". The factors that result in low safety during the operation of a pure hydrogen gas turbine are often as follows: During the operation of a pure hydrogen gas turbine, fuel is continuously supplied, and only the fuel pipeline is periodically inspected for cracks. When a relatively large crack is detected, hydrogen leakage has already occurred, resulting in low safety during the operation of the pure hydrogen gas turbine. If the above factors are solved, the effect of improving the safety during the operation of the pure hydrogen gas turbine can be achieved. To achieve this effect, in the ignition control method applicable to a pure hydrogen gas turbine of the present disclosure, before ignition, first detect whether there are cracks in each fuel branch pipeline, and predict the crack information in the fuel pipeline during the operation process, that is, at a future time point, based on the cracks detected historically, so as to predict in advance whether the crack will cause danger and know in advance before hydrogen leakage occurs. Also, because when predicting cracks, it is considered that as the operation time increases, the probability of a crack causing danger also gradually increases, so the prediction deviation of the estimation algorithm is used to correct the error, and thus the accuracy of the prediction result can be improved. Therefore, the safety during the operation of the pure hydrogen gas turbine can be further improved.

[0043] Optionally, the above-mentioned purging device may include, but is not limited to, a gas turbine purging component and a fuel pipeline purging component. The above-mentioned gas turbine purging component may be a component that supplies air from an axial compressor to purge each combustion chamber and turbine. The above-mentioned gas turbine purging component may include, but is not limited to, the above-mentioned axial compressor and an air supply pipeline. One end of the above-mentioned air supply pipeline is connected to the above-mentioned axial compressor to supply compressed air to the combustion chamber. The above-mentioned fuel pipeline purging component may be a component for purging the fuel pipeline. The above-mentioned fuel pipeline may be a pipeline for supplying fuel. The above-mentioned fuel pipeline purging component may include a nitrogen storage device and each nitrogen cut-off valve. A nitrogen cut-off valve is provided between the nitrogen storage device and one end of the fuel pipeline. Each of the above-mentioned nitrogen cut-off valves may be provided on the fuel pipeline. The nitrogen cut-off valve may be an electromagnetic valve for supplying nitrogen to the fuel pipeline.

[0044] In some alternative implementation manners of some embodiments, the above-mentioned execution subject may control the purging device included in the above-mentioned pure hydrogen gas turbine to perform a purging operation through the following steps:

[0045] First step, control the above-mentioned motor to perform a motor starting operation. Among them, the above-mentioned motor starting operation can be an operation to start the motor.

[0046] Second step, in response to determining that the combustion engine speed of the above-mentioned pure hydrogen gas turbine meets the preset speed condition, control the above-mentioned combustion engine purge assembly to perform a combustion engine purge operation. Among them, the above-mentioned combustion engine speed can be the speed of the pure hydrogen gas turbine. The above-mentioned speed condition can be that the combustion engine speed is the preset purge combustion engine speed. The above-mentioned preset purge combustion engine speed can be a speed preset for purging the gas turbine. For example, the above-mentioned preset purge combustion engine speed can be 27% of the rated speed of the pure hydrogen gas turbine. The above-mentioned combustion engine purge operation can be an operation to start the axial flow compressor to purge the inside of the pure hydrogen gas turbine.

[0047] Third step, in response to determining that the current time meets the preset extended duration condition, control the above-mentioned fuel pipeline purge assembly to perform a fuel pipeline purge operation. Among them, the above-mentioned preset extended duration condition can be that the time interval between the current time and the time when the combustion engine purge operation starts is the preset extended duration. The above-mentioned preset extended duration can be a duration preset in advance. For example, the above-mentioned preset extended duration can be 3 seconds. The fuel pipeline purge operation can be an operation to open each nitrogen cut-off valve to purge each pipeline supplying fuel.

[0048] Fourth step, in response to the current time meeting the preset fuel pipeline purge duration condition, control the above-mentioned fuel pipeline purge assembly to perform a fuel pipeline purge stop operation. Among them, the above-mentioned preset fuel pipeline purge duration condition can be that the time interval between the current time and the time when the fuel pipeline purge operation starts is the preset fuel pipeline purge duration. The above-mentioned preset fuel pipeline purge duration can be a duration preset in advance for purging the fuel pipeline. For example, the above-mentioned preset fuel pipeline purge duration can be 30 seconds. The above-mentioned fuel pipeline purge stop operation can be an operation to close each nitrogen cut-off valve.

[0049] Fifth step, in response to determining that the current time meets the preset combustion engine purge duration condition, determine the preset purge completion information as the purge completion information. Among them, the above-mentioned preset fuel pipeline purge duration condition can be that the time interval between the current time and the time when each valve is opened is the preset fuel pipeline purge duration. The above-mentioned preset fuel pipeline purge duration can be a duration preset in advance for purging the fuel pipeline. The above-mentioned fuel pipeline can be a pipeline included in the hydrogen supply pipeline assembly. For example, the above-mentioned preset fuel pipeline purge duration can be 120 seconds. The above-mentioned preset purge completion information can indicate that the purge device has completed the purge operation. For example, the above-mentioned preset purge completion information can be: "clean finish".

[0050] Step 102: In response to detecting the purging completion information, control each igniter included in the pure hydrogen gas turbine to perform an ignition operation, and control the first fuel control valve, the second fuel cut-off valve, and the third fuel cut-off valve to perform an opening operation according to the preset first ignition opening information.

[0051] In some embodiments, the above-mentioned execution entity may, in response to detecting the purging completion information, control each igniter included in the pure hydrogen gas turbine to perform an ignition operation, and control the first fuel control valve, the second fuel cut-off valve, and the third fuel cut-off valve to perform an opening operation according to the preset first ignition opening information. Among them, the number of each igniter included in the pure hydrogen gas turbine may be 10. The above-mentioned ignition operation may be an operation of simultaneously igniting 10 igniters. The above-mentioned preset first ignition opening information may represent the opening of the first fuel control valve at the initial stage of ignition set in advance. The above-mentioned preset first ignition opening information may include but is not limited to the preset first ignition opening. For example, the above-mentioned preset first ignition opening may be 10. The above-mentioned opening operation may be an operation of opening the first fuel control valve, the second fuel cut-off valve, and the third fuel cut-off valve. In practice, the above-mentioned execution entity may control the first fuel control valve, the second fuel cut-off valve, and the third fuel cut-off valve to perform an opening operation, and the opening of the first fuel control valve is the opening corresponding to the preset first ignition opening information.

[0052] In some optional implementation manners of some embodiments, the above-mentioned execution entity may control each igniter included in the pure hydrogen gas turbine to perform an ignition operation through the following steps:

[0053] The first step: Control the above-mentioned motor to perform a speed adjustment operation according to the preset first gas turbine speed. Among them, the above-mentioned preset first gas turbine speed may be the speed of the gas turbine preset for warm-up. For example, the above-mentioned preset first gas turbine speed may be 15.5% of the rated speed of the pure hydrogen gas turbine. The rated speed of the pure hydrogen gas turbine may be 5163 rpm (revolutions per minute). The above-mentioned speed reduction operation may be an operation of adjusting the speed of the gas turbine to the preset first gas turbine speed. In practice, the above-mentioned execution entity may, in response to detecting the purging completion information, control the above-mentioned motor to adjust the speed of the gas turbine to the preset first gas turbine speed.

[0054] Step 2: In response to detecting the information indicating that the speed adjustment is completed, control the above-mentioned motor to perform a speed increase operation according to a preset second gas turbine speed. Wherein, the above-mentioned information indicating that the speed adjustment is completed can indicate that the speed of the pure hydrogen gas turbine reaches a preset first gas turbine speed. The above-mentioned preset second gas turbine speed can be the speed of the pure hydrogen gas turbine at ignition preset in advance. For example, the above-mentioned preset second gas turbine speed can be 17.2% of the rated speed of the pure hydrogen gas turbine. The above-mentioned speed increase operation can be an operation to increase the speed of the pure hydrogen gas turbine. In practice, the above-mentioned execution subject can, in response to detecting the information indicating that the speed adjustment is completed, control the above-mentioned motor to adjust the speed of the pure hydrogen gas turbine to the preset second gas turbine speed.

[0055] Step 3: In response to detecting the information indicating that the speed increase is completed, control each igniter included in the above-mentioned pure hydrogen gas turbine to perform an ignition operation, where the above-mentioned information indicating that the speed increase is completed can indicate that the speed of the pure hydrogen gas turbine reaches the preset second gas turbine speed.

[0056] Thus, the pure hydrogen gas turbine can be gradually accelerated and ignited, thereby reducing the thermal stress of components such as the rotor and blades, extending the service life of the equipment, and reducing component damage.

[0057] Step 103: In response to determining that the current time meets the preset ignition duration condition, control the first fuel control valve to perform a valve opening reduction operation according to the preset second ignition opening information.

[0058] In some embodiments, the above-mentioned execution subject can, in response to determining that the current time meets the preset ignition duration condition, control the above-mentioned first fuel control valve to perform a valve opening reduction operation according to the preset second ignition opening information. Wherein, the above-mentioned preset ignition duration condition can be: the interval duration between the current time and the time when the first fuel control valve is opened is a preset first opening duration. The above-mentioned preset first opening duration can be the duration preset in advance for opening the first fuel control valve according to the preset first ignition opening information. For example, the above-mentioned preset first opening duration can be 2 seconds. The above-mentioned preset second ignition opening information can be the opening of the first fuel control valve required at ignition. It should be noted that the opening represented by the above-mentioned preset first ignition opening information is greater than the opening represented by the above-mentioned preset second ignition opening information. Thus, more hydrogen can be introduced within the preset first opening duration to discharge the nitrogen in the fuel pipeline, preventing ignition failure caused by the nitrogen in the fuel pipeline not being discharged. The above-mentioned valve opening reduction operation can be an operation to reduce the opening of the first fuel control valve. In practice, the above-mentioned execution subject can, in response to determining that the current time meets the preset ignition duration condition, reduce the opening of the first fuel control valve to the opening corresponding to the preset second ignition opening information.

[0059] Optionally, the above-mentioned preset second ignition opening information is pre-generated through the following steps:

[0060] First step, obtain the ignition hydrogen gas flow information corresponding to the above-mentioned pure hydrogen gas turbine. Among them, the above-mentioned ignition hydrogen gas flow information can characterize the flow rate of hydrogen required for the ignition of the pure hydrogen gas turbine.

Among them, the above-mentioned preset adjacent condition can be adjacent to the above-mentioned temperature monitoring information, and the corresponding serial number is greater than the serial number of the above-mentioned temperature monitoring information.

[0074] The third sub-step is to determine the temperature change value as the difference between the combustion chamber thermocouple temperature value included in the above-mentioned adjacent temperature monitoring information and the combustion chamber thermocouple temperature value included in the above-mentioned temperature monitoring information.

[0075] Then, according to the above-mentioned temperature monitoring information sequence set, the obtained temperature change values are arranged and combined to obtain a temperature change value sequence set.

[0076] After that, for each temperature change value sequence included in the above-mentioned temperature change value sequence set, a preset number of temperature change values are divided into a segmented temperature change value sequence to obtain each segmented temperature change value sequence. Among them, the above-mentioned preset number can be a preset value. For example, the above-mentioned preset number can be 30.

In practice, first, the above-mentioned execution entity can execute the following sub-steps for each same-combustion-chamber temperature change value sequence group:

[0081] Sub-step one, for each same-combustion-chamber temperature change value sequence included in the above-mentioned same-combustion-chamber temperature change value sequence group, in response to determining that any same-combustion-chamber temperature change value in the above-mentioned same-combustion-chamber temperature change value sequence is greater than the preset temperature change value, the above-mentioned same-combustion-chamber temperature change value sequence is determined as the target temperature change value sequence. Among them, the above-mentioned preset temperature change value can be a preset temperature change value representing successful combustion chamber ignition. The above-mentioned preset temperature change value can be 3 degrees Celsius.

[0082] Sub-step 2: In response to determining that the target temperature change value sequence exists in the above-mentioned same combustion chamber temperature change value sequence group, determine the combustion chamber identifier corresponding to the above-mentioned same combustion chamber temperature change value sequence group as the target combustion chamber identifier.

[0083] Then, in response to determining that each combustion chamber identifier corresponding to each of the above-mentioned same combustion chamber temperature change value sequence groups is the target combustion chamber identifier, determine that the combustion chamber ignition success information is generated and determine the preset combustion chamber ignition success information as the combustion chamber ignition success information. Wherein, the above-mentioned preset combustion chamber ignition success information can be information preset to represent the successful ignition of each combustion chamber. For example, the above-mentioned preset combustion chamber ignition success information can be "success".

[0084] Finally, in response to detecting the combustion chamber ignition success information corresponding to any same time period segmented temperature change value sequence group, and the above-mentioned valve state information indicating that the first fuel control valve is in the open state, determine the preset ignition success information as the ignition result information. Wherein, the above-mentioned preset ignition success information can be information preset to represent the successful ignition of a pure hydrogen gas turbine. For example, the above-mentioned preset ignition success information can be "1". In response to not detecting the combustion chamber ignition success information corresponding to each same time period segmented temperature change value sequence group, or the above-mentioned valve state information indicating that the first fuel control valve is in the closed state, determine the preset ignition failure information as the ignition result information.

[0085] Optionally, a pressure sensor may be provided in each of the above-mentioned combustion chambers. The position of the pressure sensor in the corresponding combustion chamber is as Figure 2 shown. Among them, Figure 2 includes combustion chamber 21 and pressure sensor 22.

[0086] In some optional implementation manners of some embodiments, the above-mentioned execution subject may generate the ignition result information according to the above-mentioned temperature monitoring information and the above-mentioned valve state information in the following manner:

[0087] First step, obtain a set of pressure monitoring information corresponding to each pressure sensor included in the above-mentioned pure hydrogen gas turbine. Wherein, the pressure monitoring information in the above-mentioned set of pressure monitoring information can correspond one-to-one to the pressure sensors in each pressure sensor. The pressure monitoring information in the above-mentioned set of pressure monitoring information can represent the pressure pulsation value detected by the pressure sensor. The pressure monitoring information may include, but is not limited to, the pressure pulsation value. In practice, the above-mentioned execution subject may obtain the set of pressure monitoring information corresponding to each pressure sensor included in the above-mentioned pure hydrogen gas turbine through a wireless connection.

[0088] Step 2: Generate ignition result information based on the above pressure monitoring information set, the above temperature monitoring information, and the above valve status information. In practice, first, for each pressure monitoring information in the above pressure monitoring information set, the above execution entity may determine the ratio of the pressure pulsation value included in the above pressure monitoring information to the preset pressure value as the pressure ratio. Wherein, the above preset pressure value may be the pressure value when the combustion chamber is not ignited, which is preset. Then, generate a first ignition result based on the above temperature monitoring information sequence set and the above valve status information. Wherein, the implementation manner of generating the first ignition result based on the above temperature monitoring information sequence set and the above valve status information is the same as that in step 107, and will not be elaborated here. Then, in response to determining that each of the determined pressure ratios is greater than or equal to the preset pressure ratio, and the first ignition result indicates that the pure hydrogen gas turbine ignition is successful, determine the preset ignition success information as the ignition result information. Wherein, the above preset pressure ratio may be the ratio of the pressure increase characterizing the successful ignition of the combustion chamber, which is preset. For example, the above preset pressure ratio may be 2. Finally, in response to determining that any of the determined pressure ratios is less than the preset pressure ratio or the first ignition result indicates that the pure hydrogen gas turbine ignition fails, determine the preset ignition failure information as the ignition result information.

[0089] Step 106: In response to determining that the ignition result information meets the preset ignition success condition, control the first fuel control valve to perform an opening holding operation.

[0090] In some embodiments, the above execution entity may control the first fuel control valve to perform an opening holding operation in response to determining that the ignition result information meets the preset ignition success condition. Wherein, the above preset ignition success condition may be that the ignition result information indicates that the pure hydrogen gas turbine ignition is successful. The above opening holding operation may be an operation in which the opening of the first fuel control valve remains unchanged.

[0091] Optionally, the above pure hydrogen gas turbine may further include an exhaust device. The above exhaust device may be a device for discharging the high-temperature exhaust gas after combustion from the pure hydrogen gas turbine and performing exhaust gas treatment on the high-temperature exhaust gas. The above exhaust device may include, but is not limited to, an exhaust pipe line assembly. The above exhaust pipe line assembly may be an assembly of pipes for discharging the high-temperature exhaust gas after combustion from the pure hydrogen gas turbine. The above exhaust device may further include an exhaust thermocouple. The above exhaust thermocouple may be a thermocouple for detecting the temperature in the exhaust pipe line. As an example, 18 exhaust thermocouples may be evenly arranged circumferentially along the pipe line in the exhaust pipe line.

[0092] In the process of adopting technical solutions to solve the technical problems in the background art, there is often another technical problem as follows: how to determine the flameout of a pure hydrogen gas turbine. In response to the above technical problem 3, the conventional solution is generally to judge by monitoring the temperature of the combustion chamber. However, the above conventional solution still has the following problems: the temperature of the combustion chamber is affected by various factors. Judging whether the pure hydrogen gas turbine has flameout only by the temperature of the combustion chamber results in a low accuracy of the judgment result, thereby causing a low safety level when the pure hydrogen gas turbine has flameout.

[0093] Considering the problems of the above conventional solution, in the face of the above technical problem 3, the following solution can be adopted:

[0094] Optionally, the above execution subject can also execute the following steps:

[0095] In the first step, in response to receiving the flameout information, control the above first fuel control valve, the above second fuel cut-off valve, and the above third fuel cut-off valve to perform a closing operation. The above flameout information can indicate that the pure hydrogen gas turbine needs to be flameout. For example, the above flameout information can be "off". The above closing operation can be an operation to close the valve.

[0096] In the second step, in response to detecting the valve closing information set corresponding to the above first fuel control valve, the above second fuel cut-off valve, and the above third fuel cut-off valve, obtain the current temperature monitoring information set corresponding to each combustion chamber thermocouple and the exhaust thermocouple temperature monitoring information corresponding to the exhaust thermocouple. Among them, the valve closing information in the valve closing information set can be the information that the corresponding valve has been closed. Among them, the combustion chamber thermocouple in each of the above combustion chamber thermocouples and the current temperature monitoring information in the current temperature monitoring information set can correspond one by one. The current temperature monitoring information can indicate the change in the temperature value detected by the corresponding combustion chamber thermocouple relative to the temperature value one second ago. The current temperature monitoring information can include, but is not limited to, the current temperature change value. The above current temperature change value can be the difference between the temperature value detected by the corresponding combustion chamber thermocouple and the temperature one second ago. The above exhaust thermocouple temperature monitoring information can indicate the temperature detected by the exhaust thermocouple. The above exhaust thermocouple temperature monitoring information can include, but is not limited to, the ignition temperature value and the current temperature value. The above ignition temperature value can be the minimum value among the temperature values detected by the exhaust thermocouple during the normal operation of the pure hydrogen gas turbine. The above current temperature value can be the temperature value detected by the exhaust thermocouple at the current time.

[0097] Step 3: Generate flameout result information based on the above current temperature monitoring information set and the above exhaust thermocouple temperature monitoring information. Among them, the above flameout result information can characterize whether the pure hydrogen gas turbine has flamed out. In practice, the above execution entity can, in response to determining that each current temperature change value included in the above current temperature monitoring information set is greater than a preset flameout temperature change value, and the difference between the ignition temperature value and the current temperature value included in the above exhaust thermocouple temperature monitoring information is greater than a preset temperature drop value, determine the preset flameout success information as the flameout result information. The above preset flameout temperature change value can be a preset temperature change value characterizing the flameout of the combustion chamber. For example, the above preset flameout temperature change value can be 10 degrees Celsius. The above preset temperature drop value can be a preset temperature drop value of the temperature in each combustion chamber flameout exhaust pipeline. For example, the above preset temperature drop value can be 10 degrees Celsius. The above preset flameout success information can be preset information characterizing the successful flameout of the pure hydrogen gas turbine.

[0098] Step 4: In response to determining that the above flameout result information meets the preset flameout condition, send the preset flameout success information to the user terminal. Among them, the above preset flameout condition can be that the flameout result information characterizes the successful flameout of the pure hydrogen gas turbine. The above user terminal can be the terminal of the user who controls the opening and closing of the pure hydrogen gas turbine. Figure 4 It is a test site diagram of some embodiments of the ignition control method for a pure hydrogen gas turbine according to the present disclosure.

[0099] Step 5: In response to determining that the above ignition result information meets the preset ignition failure condition, control the above first fuel control valve, the above second fuel cut-off valve, and the above third fuel cut-off valve to perform a closing operation. Among them, the above preset ignition failure condition can be that the ignition result information characterizes the ignition failure of the pure hydrogen gas turbine.

[0100] Step 6: Control the above purging device to perform the above purging operation again.

[0101] The above technical solution and its related content are an inventive point of an embodiment of the present disclosure, which solves the technical problem of "low safety when a pure hydrogen gas turbine shuts down". The factors that lead to low safety when a pure hydrogen gas turbine shuts down are often as follows: It is judged by monitoring the temperature of the combustion chamber. However, the above conventional solution still has the following problems: The temperature of the combustion chamber is affected by various factors. Judging whether the pure hydrogen gas turbine shuts down only by the temperature of the combustion chamber results in low accuracy of the judgment result, thus causing low safety when the pure hydrogen gas turbine shuts down. If the above factors are solved, the effect of improving the safety when the pure hydrogen gas turbine shuts down can be achieved. To achieve this effect, the ignition control method applicable to a pure hydrogen gas turbine in the present disclosure judges whether the pure hydrogen gas turbine shuts down by comprehensively judging the combustion chamber temperature and the exhaust gas temperature. Thus, the accuracy of the judgment result can be improved, and further, the safety when the pure hydrogen gas turbine shuts down can be improved.

[0102] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: The ignition control method applicable to a pure hydrogen gas turbine according to some embodiments of the present disclosure can improve the safety of the ignition operation of the pure hydrogen gas turbine. Specifically, in actual operation of the pure hydrogen gas turbine, the number of times of ignition failure causing the unit to trip is relatively large, and the reason for the low safety is that: when igniting through the flame connecting pipe, when the flame propagation in the flame connecting pipe gets out of control, the risk of deflagration or flashback is relatively high, thus resulting in low safety during the ignition process. Based on this, the ignition control method applicable to a pure hydrogen gas turbine according to some embodiments of the present disclosure is applied to the pure hydrogen gas turbine. First, in response to receiving the ignition start information, control the purging device included in the above-mentioned pure hydrogen gas turbine to perform a purging operation. Among them, the above-mentioned pure hydrogen gas turbine further includes a motor, a combustion device, and a fuel supply device. The above-mentioned combustion device includes each combustion chamber, and each combustion chamber included in each of the above-mentioned combustion chambers is provided with an igniter and a combustion chamber thermocouple. The above-mentioned fuel supply device includes a hydrogen supply pipeline assembly, and the above-mentioned hydrogen supply pipeline assembly includes a first fuel control valve, a second fuel cut-off valve, and a third fuel cut-off valve. Thus, each pipeline in the pure hydrogen gas turbine and the inside of the gas turbine can be purged, thereby cleaning the impurities and air existing in the pipeline and the inside of the gas turbine, and further preventing ignition failure and explosion. Second, in response to detecting the purging completion information, control each igniter included in the above-mentioned pure hydrogen gas turbine to perform an ignition operation, and control the above-mentioned first fuel control valve, the above-mentioned second fuel cut-off valve, and the above-mentioned third fuel cut-off valve to perform an opening operation according to the preset first ignition opening information. Thus, ignition operations can be performed on each combustion chamber included in the pure hydrogen gas turbine simultaneously. After that, in response to determining that the current time meets the preset ignition duration condition, control the above-mentioned first fuel control valve to perform an opening degree reduction operation according to the preset second ignition opening information. Thus, the opening degree of the fuel valve can be adjusted to the opening degree for normal ignition. Then, in response to determining that the current time meets the preset ignition waiting duration condition, obtain the temperature monitoring information sequence set corresponding to each combustion chamber thermocouple included in the above-mentioned pure hydrogen gas turbine and the valve state information of the above-mentioned first fuel control valve. Thus, the temperature information and fuel supply information of the combustion chamber can be obtained, which can be used to determine whether the ignition is successful. Immediately afterwards, generate ignition result information according to the above-mentioned temperature monitoring information sequence set and the above-mentioned valve state information. Thus, it can be determined whether the ignition is successful. Finally, in response to determining that the above-mentioned ignition result information meets the preset ignition success condition, control the above-mentioned first fuel control valve to perform an opening degree holding operation. Thus, when the pure hydrogen gas turbine ignites successfully, keep the pure hydrogen gas turbine running normally. Also because when performing the ignition operation on the pure hydrogen gas turbine, each igniter performs the ignition operation on each combustion chamber simultaneously, without the need for flame connection through a flame connecting pipe, thereby improving the safety and success rate of the ignition operation. Thus, the safety of the ignition operation of the pure hydrogen gas turbine can be improved.
