[0059] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0060] Solid Oxide Fuel Cell (SOFC) is a highly efficient new energy power generation device that can directly convert the chemical energy of methane into electrical energy and thermal energy. Its combined heat and power efficiency can reach more than 70%, and it is widely used in the field of distributed power generation. During the power generation process, the SOFC power generation system will increase or decrease the power according to demand. When adjusting the power, it is very necessary to ensure the stability and reliability of the system. At present, when the power of the SOFC power generation system is increased or decreased, it mainly relies on complex manual operations. However, the above method has the problem of inaccurate power regulation. The present application provides a power automatic regulation method, which aims to solve the above technical problems. The following embodiments will specifically illustrate the power automatic regulation method described in the present application.

[0061] The power automatic adjustment method provided in the embodiment of the present application can be applied to Figure 1 In the SOFC power generation system shown, the SOFC power generation system includes a control device 101 and a plurality of power generation devices 102, wherein the plurality of power generation devices 102 include power generation device 1, power generation device 2...power generation device N, and the control device 101 is connected to each power generation device 102, wherein the control device 101 is used to control the power generation device 102 to perform corresponding operations through a control signal. The control device 101 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. In actual application, such as Figure 2As shown, the power generation equipment 102 includes a water supply pump 6, a nitrogen stop valve 10, a gas stop valve 9, a blower 8, a steam generator 1, a mixer 2, a reformer 3, a stack 5, an inverter 11, a tail gas burner 4, an induced draft fan 7, etc. The operating principle of the SOFC power generation system is as follows: the water supply pump 6 provides pure water, and the steam generator 1 generates high-temperature steam from the pure water; the nitrogen stop valve 10 is purged before the SOFC power generation system is heated, and the gas stop valve 9 provides methane; the mixer 2 mixes methane with high-temperature steam and inputs it into the reformer 3, and a high-temperature reforming reaction of methane and water is carried out in the reformer 3, and the reformer 3 transmits the high-temperature reforming reactant to the stack 5, and the O2- at the cathode of the stack 5 is transferred to the anode through the solid oxide electrolyte in a molten state at high temperature and forms a current output to the inverter 11, and the inverter 11 realizes power generation. The blower 8 provides air for the stack 5, the tail gas burner 4 recovers energy, and the induced draft fan 7 controls the exhaust gas emission.

[0062] Those skilled in the art will understand that Figure 1 The structure shown in the figure is only a block diagram of a part of the structure related to the scheme of the present application, and does not constitute a limitation on the SOFC power generation system to which the scheme of the present application is applied. The specific SOFC power generation system may include more or fewer components than those shown in the figure, or combine certain components, or have a different arrangement of components.

[0063] In one embodiment, Figure 3 As shown, a power automatic adjustment method is provided, which is applied to Figure 1 The control device in the example is used to illustrate, including the following steps:

[0064] S201, after detecting that an inverter in a power generation system is switched on, initializing control parameters of a first power generation device in the power generation system according to a control parameter library in a preset parameter library.

[0065] Among them, the preset parameter library includes at least one of a current increment parameter library, a control parameter library, a current parameter library and a state parameter library. The current increment parameter library represents the correspondence between different operating stages and different current increments, the control parameter library represents the correspondence between different operating stages and different control parameters, the current parameter library represents the correspondence between different operating stages and different current parameters, and the state parameter library represents the correspondence between different operating stages and different state parameters. The first power generation equipment includes a feed water pump, a gas shut-off valve and a blower. The control parameters of the first power generation equipment include the feed water flow of the feed water pump, the gas flow of the gas shut-off valve, the air flow of the blower and the water-carbon ratio. The control parameters of the first power generation equipment can be represented by a matrix [C]. It represents the feed water flow of the feed water pump, the gas flow of the gas shut-off valve, the air flow of the blower and the water-carbon ratio through the elements C1~C4 contained in the matrix [C]. Different operating stages can be reflected by current parameters.

[0066] In the embodiment of the present application, the control device can construct a control parameter library in advance according to the correspondence between the operation stage of the power generation system and the control parameters of the first power generation device. For example, the power generation system has N operation stages, and different operation stages correspond to different current parameters, so the control parameter library includes the control parameters of the first power generation device under operation stage 1, the control parameters of the first power generation device under operation stage 2...the control parameters of the first power generation device under operation stage N, that is, the control parameter library [Cu] is an N*4-dimensional array. After the control parameter library is created, the control parameter library can be stored in a table or other manner under the first preset path. When the inverter in the power generation system is detected to be closed, that is, when the AC side switch is detected to be turned on in the power generation system, the control device can obtain the closing signal, and the control device can determine that the inverter in the power generation system is closed successfully. Then, the control device can obtain the control parameter library from the first preset path, and then initialize the control parameters of the first power generation device in the power generation system according to the control parameter library, and determine whether the initialization is successful according to the control parameters of the first power generation device after the initialization operation and the control parameter library. Specifically, the control device can obtain the initial control parameters of the initial stage of the first power generation device in the power generation system from the control parameter library, and then adjust the control parameters of the current stage of the first power generation device to the initial control parameters, thereby completing the initialization operation of the control parameters of the first power generation device in the power generation system.

[0067] S202, when the control parameters of the first power generation device are successfully initialized, the power of the current operation stage is adjusted according to the preset parameter library.

[0068] The preset parameter library includes at least one of a current increment parameter library, a control parameter library, a current parameter library and a state parameter library.

[0069] In the embodiment of the present application, the control device can construct a current increment parameter library in advance according to the corresponding relationship between the operation stage of the power generation system and the current increment of each power generation device in the power generation system. For example, the power generation system has N operation stages, and different operation stages correspond to different current parameters, so the current increment parameter library includes the current increment of each power generation device in the power generation system under operation stage 1, the current increment of each power generation device in the power generation system under operation stage 2... The current increment of each power generation device in the power generation system under operation stage N-1, that is, the current increment parameter library ΔIu is (N-1)*1 dimensional data. After the current increment parameter library is created, the current increment parameter library can be stored in a table or other manner under the second preset path. The control device can construct a current parameter library in advance according to the corresponding relationship between the operation stage of the power generation system and the current parameters of each power generation device in the power generation system. For example, the power generation system has N operation stages, and the current parameter library includes the current parameters of each power generation device in the power generation system under operation stage 1, the current parameters of each power generation device in the power generation system under operation stage 2... The current parameters of each power generation device in the power generation system under operation stage N-1, that is, the current parameter library Iu is an N*1 dimensional array. After the current parameter library is created, the current parameter library can be stored in a table or other manner under the third preset path. The control device can construct a state parameter library in advance according to the corresponding relationship between the operating stage of the power generation system and the state parameters of each power generation device in the power generation system. For example, the power generation system has N operating stages, and different operating stages correspond to different current parameters, so the state parameter library includes the state parameters of each power generation device in the power generation system under operating stage 1, the state parameters of each power generation device in the power generation system under operating stage 2... The state parameters of each power generation device in the power generation system under operating stage N, that is, the state parameter library [Su] includes [Tu], [Fu], [ΔFu], Pu and Uu, where Iu, Pu, Usu are N*1-dimensional arrays, [Fu] is an N*m-dimensional array, [Tu] is an N*m-dimensional array, [ΔFu] is an N*2-dimensional array, and [Uu] is an N*o-dimensional array. After the state parameter library is created, the state parameter library can be stored in a table or other manner under the fourth preset path. The state parameters of each power generation device in the power generation system include the temperature parameter [T] or pressure parameter [F] of each power generation device in the power generation system, the pressure fluctuation parameter ΔF1 of the feed water pump, the pressure fluctuation parameter of the reformer, the voltage parameter ΔF2 of the fuel cell stack, the power P of the power generation system and the voltage U of the power generation system, wherein the temperature parameter [T] of each power generation device includes elements T1~Tm, m is the number of power generation devices in the power generation system, [F] includes elements F1~Fm, ΔF1 and ΔF2 constitute [ΔF], therefore, the state parameter [S] of the second power generation device includes [T], [F], [ΔF], P and U.It should be noted that the first preset path, the second preset path, the third preset path and the fourth preset path may be the same as each other, may be different from each other, or may be partially the same. The above-mentioned current increment parameter library, control parameter library, current parameter library and state parameter library may be stored in one table or in different tables.

[0070] When the control device determines that the control parameters of the first power generation device are successfully initialized based on the above steps, the preset parameter library can be obtained from the preset path, that is, the control parameter library can be obtained from the first path, the current increment parameter library can be obtained from the second path, the current parameter library can be obtained from the third path, and the state parameter library can be obtained from the fourth preset path, and then the power of the current operation stage can be adjusted according to the preset parameter library to obtain the adjusted power. Specifically, the process of adjusting the power of the current operation stage can be to first increase the power of the current operation stage in steps according to the operation stage, and verify the power after each increase. If the verification is passed, continue to increase until the target power is reached. If the verification is not passed, the power is reduced, and after stabilization for a period of time, the above steps are repeated to ensure that the power generation system adjusts the power to the target power while maintaining stability. Optionally, since the power and current of the power generation system are in direct proportion, the power adjustment can be achieved by adjusting the current, so the current of the current operation stage can be adjusted according to the preset parameter library to obtain the adjusted current, and then the adjusted power can be determined according to the adjusted current and the voltage of the power generation system.

[0071] The power automatic regulation method provided in the embodiment of the present application is to initialize the control parameters of the first power generation device in the power generation system according to the control parameter library in the preset parameter library after detecting that the inverter in the power generation system is closed, and then adjust the power of the current operation stage according to the preset parameter library when the control parameters of the first power generation device are successfully initialized. Among them, the preset parameter library includes at least one of a current increment parameter library, a control parameter library, a current parameter library and a state parameter library. In the above method, when performing automatic power regulation of the power generation system, by directly calling the pre-built preset parameter library, the operation steps of the power regulation of the power generation system can be simplified, thereby improving the degree of automatic control of the power generation system. At the same time, it also avoids the problem of misoperation that may occur when relying on manual power regulation, thereby improving the accuracy of power regulation.

[0072] In one embodiment, Figure 4 As shown, the "adjusting the power of the current operation stage according to the preset parameter library" in the above step S202 includes:

[0073] S301, adjusting the power of the current operation stage according to the current increment parameter library and the control parameter library, and determining whether the adjusted power generation system is in a stable state after a first preset time period.

[0074] In an embodiment of the present application, when the control device determines that the control parameters of the first power generation device are successfully initialized, it can obtain the control parameter library from the first path and the current increment parameter library from the second path, and then adjust the control parameters of the current operation stage according to the control parameter library, and adjust the current parameters of the current operation stage according to the current increment parameter library, and after an interval of a first preset time period, determine whether the adjusted power generation system is in a stable state.

[0075] Optionally, the control device can adjust the current in the current stage according to the current increment parameter library, and then determine whether the adjusted power generation system is in an initial stable state according to the adjusted current, and then adjust the control parameters of the current operation stage according to the control parameter library, and then determine whether the adjusted power generation system is in a final stable state according to the adjusted state parameters.

[0076] Specifically, Figure 5 As shown, the above step S301 of "adjusting the power of the current operation stage according to the current increment parameter library and the control parameter library" includes:

[0077] S3011, obtaining a current increment corresponding to the next operation stage from a current increment parameter library, and obtaining a control parameter corresponding to the next operation stage from a control parameter library.

[0078] In an embodiment of the present application, after obtaining the current increment parameter library and the control parameter library, the control device can obtain the current increment corresponding to the next operating stage from the current increment parameter library, and obtain the control parameter corresponding to the next operating stage from the control parameter library.

[0079] S3012, adjust the current of the current stage according to the current increment corresponding to the next operating stage, and after an interval of a second preset time period, adjust the control parameters of the current operating stage according to the control parameters corresponding to the next operating stage to achieve power increase regulation of the current operating stage.

[0080] In an embodiment of the present application, the current of the current stage is adjusted according to the current increment corresponding to the next operating stage to obtain an adjusted current. For example, the adjusted current is the sum of the current I{k} of the current stage and the current increment ΔI{k+1} corresponding to the next operating stage. To ensure current stability, after an interval of a second preset time period, it is determined whether the power generation system after current adjustment is in a stable state. On the premise that the power generation system after current adjustment is in a stable state, the control parameters of the current operating stage are adjusted according to the control parameters corresponding to the next operating stage. For example, the control parameter [Cu]{k} of the current stage is adjusted to the control parameter [Cu]{k+1} corresponding to the next operating stage, so as to achieve power increase regulation of the current operating stage.

[0081] Specifically, Figure 6 As shown, the "determining whether the adjusted power generation system is in a stable state" in the above step S301 includes:

[0082] S3013, obtaining a current corresponding to the next operation stage from a current parameter library, and obtaining a state parameter corresponding to the next operation stage from a state parameter library.

[0083] In an embodiment of the present application, the control device can obtain a current parameter library from the third path and a state parameter library from the fourth path. After obtaining the current parameter library and the state parameter library, the current corresponding to the next operating stage can be obtained from the current parameter library, and the state parameter corresponding to the next operating stage can be obtained from the state parameter library.

[0084] S3014, determining whether the adjusted current meets a first threshold requirement.

[0085] Among them, the first threshold requirement is the threshold requirement of the current corresponding to the next operating stage, for example, I{k+1}∈Iu{k+1} ± 5% Iu{k+1}, I{k+1} is the current corresponding to the next operating stage, and Iu{k+1} is the current corresponding to the next operating stage in the current parameter library.

[0086] In an embodiment of the present application, after the control device adjusts the current in the current stage according to the current increment corresponding to the next operating stage, it can determine whether the adjusted current meets the first threshold requirement to determine whether the power generation system after current adjustment is in a stable state.

[0087] S3015, if the adjusted current meets the first threshold requirement, determine whether the state parameter after adjusting the control parameter meets the second threshold requirement, and when the state parameter after adjusting the control parameter meets the second threshold requirement, determine that the adjusted power generation system is in a stable state.

[0088] Among them, the second threshold requirement is the threshold requirement of the state parameter corresponding to the next operating stage, for example, [S]{k+1}∈[Su]{k+1} ± 5% [Su]{k+1}, [S]{k+1} is the state parameter corresponding to the next operating stage, and [Su]{k+1} is the state parameter corresponding to the next operating stage in the state parameter library.

[0089] In an embodiment of the present application, if the adjusted current meets the first threshold requirement, it means that the power generation system after current adjustment is in a stable state. Then, the control parameters of the current operation stage can be adjusted according to the control parameters corresponding to the next operation stage, and then it is determined whether the state parameters after adjusting the control parameters meet the second threshold requirement. If the state parameters after adjusting the control parameters meet the second threshold requirement, it is determined that the adjusted power generation system is in a stable state.

[0090] S3016: If the adjusted current does not meet the first threshold requirement, or the state parameter after adjusting the control parameter does not meet the second threshold requirement, it is determined that the adjusted power generation system is not in a stable state.

[0091] In the embodiment of the present application, if the adjusted current does not meet the first threshold requirement, or the state parameter after adjusting the control parameter does not meet the second threshold requirement, it is determined that the adjusted power generation system is not in a stable state.

[0092] S302, if the adjusted power generation system is in a stable state, determine whether the adjusted power meets the target power, and if the adjusted power does not meet the target power, return to execute the step of increasing the power of the current operation stage according to the current increment parameter library and the control parameter library.

[0093] In an embodiment of the present application, if the control device determines that the adjusted power generation system (corresponding to the k+1 operating stage) is in a stable state based on the above steps, it determines whether the adjusted power meets the target power, and if the adjusted power does not meet the target power, continues to increase and adjust the power of the k+1 operating stage according to the current increment parameter library and the control parameter library, and so on, increases and adjusts the power of the k+2 operating stage, increases and adjusts the power of the k+3 operating stage... until the adjusted power meets the target power, that is, returns to execute the step of increasing and adjusting the power of the current operating stage according to the current increment parameter library and the control parameter library (step S301).

[0094] Specifically, Figure 7 As shown, the "determining whether the adjusted power meets the target power" in the above step S302 includes:

[0095] S3021, determining whether the adjusted current meets a third threshold requirement.

[0096] The third threshold requirement is a threshold requirement of the target current, for example, I{k+1}<Ig-5% Ig, where Ig represents the target current.

[0097] In the embodiment of the present application, after determining that the regulated power generation system is in a stable state, the control device may obtain the regulated current and determine whether the regulated current meets the third threshold requirement.

[0098] S3022: If the adjusted current meets the third threshold requirement, determine that the adjusted power meets the target power.

[0099] In the embodiment of the present application, if the adjusted current meets the third threshold requirement, that is, I{k+1} < Ig-5% Ig, it is determined that the adjusted power meets the target power.

[0100] S3023: If the adjusted current does not meet the third threshold requirement, it is determined that the adjusted power does not meet the target power.

[0101] In the embodiment of the present application, if the adjusted current does not meet the third threshold requirement, that is, I{k+1}≥Ig-5% Ig, it is determined that the adjusted power does not meet the target power.

[0102] S303: If the adjusted power generation system is not in a stable state, the power of the current operation stage is reduced and adjusted according to the current increment parameter library and the control parameter library.

[0103] In an embodiment of the present application, if the control device determines based on the above steps that the power generation system is not in a stable state, the power of the current operation stage is negatively adjusted according to the current increment parameter library and the control parameter library to achieve a power reduction adjustment for the current operation stage.

[0104] Specifically, Figure 8 As shown, the above step S303 of "reducing and adjusting the power of the current operation stage according to the current increment parameter library and the control parameter library" includes:

[0105] S3031, obtaining a current increment corresponding to the current operation stage from a current increment parameter library, and obtaining a control parameter corresponding to the previous operation stage from a control parameter library.

[0106] In the embodiment of the present application, after the control device determines that the adjusted power generation system is not in a stable state, the operation stage at this time is the k+1 operation stage, and then the control device can obtain the current increment ΔI{k+1} corresponding to the current operation stage from the current increment parameter library, and obtain the control parameter [Cu]{k} corresponding to the previous operation stage from the control parameter library.

[0107] S3032, adjusting the current of the current stage according to the current increment corresponding to the current operation stage, and adjusting the control parameters of the current operation stage according to the control parameters corresponding to the previous operation stage, so as to reduce the power of the current operation stage.

[0108] In an embodiment of the present application, after the control device obtains the current increment corresponding to the current operation stage and the control parameters corresponding to the previous operation stage based on the above steps, it can negatively adjust the current of the current stage according to the current increment corresponding to the current operation stage, and negatively adjust the control parameters of the current operation stage according to the control parameters corresponding to the previous operation stage, so as to achieve power reduction regulation of the current operation stage, for example, adjusting -ΔI{k+1}, [Cu]{k} in sequence, and returning to the k stage.

[0109] The method described in the embodiment of the present application can put the system in a stable stage by initializing the control parameters of the first power generation equipment in the power generation system before increasing the power of the power generation system, thereby avoiding errors caused by system instability and improving power regulation accuracy.

[0110] In one embodiment, Fig. 9 As shown, the above method also includes:

[0111] S401, obtaining current parameters and state parameters of the power generation system after initialization operation.

[0112] Among them, the current parameter after the initialization operation is the current parameter of the power generation system after the initialization operation. The state parameters after the initialization operation include the temperature parameters or pressure parameters of each power generation equipment in the power generation system after the initialization, the pressure fluctuation parameters of the water supply pump after the initialization, the pressure fluctuation parameters of the reformer after the initialization, the voltage parameters of the stack, the power of the power generation system after the initialization, and the voltage of the power generation system after the initialization.

[0113] In the embodiment of the present application, after the control device performs an initialization operation on the control parameters of the first power generation device in the power generation system according to the control parameter library in the preset parameter library, the current parameter and state parameter of the power generation system after the initialization operation can be obtained. Specifically, the current parameter I{k} after the initialization operation can be obtained through the current sensor, and the state parameter [S]{k} after the initialization operation can be obtained through the pressure sensor and the temperature sensor, where k is the initial time.

[0114] S402, obtaining an initial current parameter corresponding to the initial operation stage from a current parameter library, and obtaining an initial state parameter corresponding to the initial operation stage from a state parameter library.

[0115] In an embodiment of the present application, after the control device obtains the current parameter I{k} and the state parameter [S]{k} after the initialization operation based on the above steps, it can obtain the initial current parameter Iu{k} at the initial moment k from the current parameter library Iu, and obtain the initial state parameter [S]{k} at the initial moment from the state parameter library [Su].

[0116] S403, determining whether the current parameters after the initialization operation are consistent with the initial current parameters, and determining whether the state parameters after the initialization operation are consistent with the initial state parameters.

[0117] In the embodiment of the present application, the control device can determine whether the current parameter after the initialization operation is consistent with the initial current parameter, and determine whether the state parameter after the initialization operation is consistent with the initial state parameter. Specifically, it can determine whether the current parameter after the initialization operation meets the threshold requirement of the initial current parameter, and determine whether the state parameter after the initialization operation meets the threshold requirement of the initial state parameter. For example, it can be determined by I{k}∈Iu{k} ± 5% Iu{k}, [S]{k}∈[Su]{k} ± 5% [Su]{k}.

[0118] S404: If yes, it is determined that the control parameters of the power generation system are initialized successfully; if no, it is determined that the control parameters of the power generation system are initialized unsuccessfully.

[0119] In the embodiment of the present application, if the current parameter after the initialization operation is consistent with the initial current parameter and the state parameter after the initialization operation is consistent with the initial state parameter, it is determined that the control parameter of the power generation system is successfully initialized. If the current parameter after the initialization operation is inconsistent with the initial current parameter, and / or the state parameter after the initialization operation is inconsistent with the initial state parameter, it is determined that the control parameter initialization of the power generation system has failed. Optionally, after determining that the control parameter of the power generation system is successfully initialized, the initial state indicator light can be controlled to turn green.

[0120] The method described in the embodiment of the present application can ensure that the current of the power generation system is in a stable state by initializing the power generation system and increasing the power if the initialization operation is successful, thereby improving the stability and reliability of the system.

[0121] In one embodiment, the method further includes: responding to a power reduction adjustment instruction triggered by a user, and reducing the power of the current operation stage according to the current increment parameter library and the control parameter library.

[0122] The power automatic adjustment operation instruction is used to increase or decrease the power. The adjustment types include power increase adjustment and power decrease adjustment.

[0123] In the embodiment of the present application, when adjusting the power of the current operation stage of the power generation system, it is also possible to receive the power automatic adjustment operation instruction triggered by the user in the control interface, and adjust the power of the current operation stage according to the adjustment type indicated by the power automatic adjustment operation instruction. Specifically, if the adjustment type is power pull-up adjustment, the control device can return to execute the initialization operation of the control parameters of the first power generation device in the power generation system according to the control parameter library, and when the control parameters of the first power generation device are successfully initialized, the power of the current operation stage is adjusted according to the current increment parameter library and the control parameter library, that is, the current of the power generation system is reduced step by step according to +ΔIu{k}, and the control parameter [Cu]{k} is adjusted step by step; if the adjustment type is power reduction adjustment, the control device can adjust the power of the current operation stage according to the current increment parameter library and the control parameter library, that is, the current of the power generation system is reduced step by step according to -ΔIu{k}, and the control parameter [Cu]{k} is adjusted step by step.

[0124] Optionally, the user can adjust the power of the power generation system in manual mode. Specifically, the user can refer to the current increment parameter library ΔIu and the control parameter library [Cu] to first increase the current I and then change the control parameter [C]. If I∈Iu ± 5% Iu, [S]∈[Su] ± 5% [Su], the module status indicator is green, indicating that the manual debugging is successful, otherwise it indicates that the debugging has failed. If the manual debugging fails, the power increase operation is not allowed.

[0125] The method described in the embodiment of the present application can quickly adjust the power output according to real-time needs by receiving user instructions, thereby improving the flexibility of the power generation system. Moreover, by gradually adjusting the current and control parameters, the system fluctuation caused by large adjustments can be effectively reduced, and the stability of the system operation can be maintained.

[0126] Based on all the above embodiments, a method for automatic power regulation is also provided, the method comprising:

The preset parameter library includes at least one of a current increment parameter library, a control parameter library, a current parameter library, and a state parameter library.

[0128] S502, obtaining current parameters and state parameters of the power generation system after the initialization operation is performed.

[0130] S504, determining whether the current parameters after the initialization operation are consistent with the initial current parameters, and determining whether the state parameters after the initialization operation are consistent with the initial state parameters.

[0131] S505: If yes, it is determined that the control parameters of the power generation system are initialized successfully; if no, it is determined that the control parameters of the power generation system are initialized unsuccessfully.

[0132] S506, when the control parameters of the first power generation device are successfully initialized, the current increment corresponding to the next operation stage is obtained from the current increment parameter library, and the control parameters corresponding to the next operation stage are obtained from the control parameter library.

[0133] S507, adjust the current of the current stage according to the current increment corresponding to the next operating stage, and after an interval of a second preset time period, adjust the control parameters of the current operating stage according to the control parameters corresponding to the next operating stage to achieve power increase regulation of the current operating stage, and after an interval of a first preset time period, obtain the current corresponding to the next operating stage from the current parameter library, and obtain the state parameters corresponding to the next operating stage from the state parameter library.

[0134] S508, determining whether the adjusted current meets a first threshold requirement. The first threshold requirement is a threshold requirement of the current corresponding to the next operation stage.

[0135] S509, if the adjusted current meets the first threshold requirement, determine whether the state parameter after adjusting the control parameter meets the second threshold requirement, and if the state parameter after adjusting the control parameter meets the second threshold requirement, determine that the adjusted power generation system is in a stable state. The second threshold requirement is the threshold requirement of the state parameter corresponding to the next operation stage.

[0136] S510: If the adjusted current does not meet the first threshold requirement, or the state parameter after the control parameter is adjusted does not meet the second threshold requirement, it is determined that the adjusted power generation system is not in a stable state.

[0137] S511, if the adjusted power generation system is in a stable state, determine whether the adjusted current meets a third threshold requirement; the third threshold requirement is a threshold requirement of the target current.

[0138] S512: If the adjusted current meets the third threshold requirement, determine that the adjusted power meets the target power.

[0139] S513, if the adjusted current does not meet the third threshold requirement, it is determined that the adjusted power does not meet the target power, and when the adjusted power does not meet the target power, it returns to execute the step of increasing and adjusting the power of the current operation stage according to the current increment parameter library and the control parameter library.

[0140] S514, if the adjusted power generation system is not in a stable state, the current increment corresponding to the current operation stage is obtained from the current increment parameter library, and the control parameter corresponding to the previous operation stage is obtained from the control parameter library.

[0141] S515, adjusting the current of the current stage according to the current increment corresponding to the current operation stage, and adjusting the control parameters of the current operation stage according to the control parameters corresponding to the previous operation stage, so as to reduce the power of the current operation stage.

[0142] S516, responding to the power reduction adjustment instruction triggered by the user, reducing the power of the current operation stage according to the current increment parameter library and the control parameter library.

[0143] In the present application embodiment, Fig.10 As shown, when the control device automatically adjusts the power of the SOFC power generation system (also called SOFC module), it can first monitor the temperature of the module and determine whether the temperature of the module meets the power generation conditions. If not, continue monitoring. If so, perform module initialization operations. Specifically, the control parameters of the first power generation device at the current moment can be adjusted to the initial control parameters, and determine whether the module initialization operation is successful. If the initialization operation fails, it indicates an abnormality and an alarm is issued. If the initialization operation is successful, it is determined to obtain the current parameters and state parameters of the stable operation after the initialization operation, and obtain the target current, and then use the current increment parameter library and the control parameter library to pull up the power of the power generation system in stage k, and obtain the state parameters of stage k+1 and the current parameters of stage k+1. Then, it is determined whether the state parameters of the k+1 stage meet the state parameters corresponding to the k+1 stage in the state parameter library and whether the current parameters of the k+1 stage meet the current parameters corresponding to the k+1 stage in the current parameter library. If both are satisfied, it is determined whether the current parameters of the k+1 stage reach the target current. If reached, the power pull-up operation is terminated. If not reached, the power of the k+1 stage of the power generation system is pulled up according to the current increment parameter library and the control parameter library, and the above steps are executed repeatedly until the current parameters of the power generation system reach the target current. Similarly, when it is necessary to reduce the power of the power generation system, the power of the k stage of the power generation system is reduced according to the current parameters and state parameters of the current stage of the power generation system through the current increment parameter library and the control parameter library, and is reduced to the target value in steps. In the above steps, alarm processing is performed for abnormal situations.
