These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0068] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0069] Hydrogen production systems using water electrolysis typically consist of multiple electrolyzers, and each electrolyzer needs to be started up separately during the startup phase.

[0070] Currently, the water electrolysis hydrogen production system is usually started manually one by one. Operators are required to check the parameters of each electrolyzer in turn to ensure they are normal. After confirming that the parameters of each electrolyzer are normal, the electrolyzer is started manually.

[0071] However, since large-scale proton exchange membrane (PEM) water electrolysis hydrogen production systems typically consist of dozens to hundreds of electrolyzers, manually starting each one is extremely time-consuming.

[0072] In view of this, this application proposes a startup method that acquires the operating parameters and performance parameters of multiple electrolyzers in a water electrolysis hydrogen production system; determines whether each electrolyzer meets the startup conditions based on the operating parameters of the multiple electrolyzers; generates an alarm message corresponding to at least one electrolyzer when at least one electrolyzer fails to meet the startup conditions, and stops the startup of multiple electrolyzers in the water electrolysis hydrogen production system, the alarm message including the electrolyzer identifier, abnormal operating parameters of the electrolyzer, and handling prompts for the electrolyzer; and acquires the available power capacity of the power supply for the water electrolysis hydrogen production system when multiple electrolyzers meet the startup conditions, and starts the multiple electrolyzers in the water electrolysis hydrogen production system based on the performance parameters of the multiple electrolyzers and the available power capacity of the power supply. In the above method, by automatically collecting the operating parameters and performance parameters of multiple electrolyzers and combining the verification logic of the operating parameters, the method automatically determines whether each electrolyzer meets the startup conditions, eliminating the need for manual parameter checking of each electrolyzer, and significantly reducing the startup time of a large-scale PEM water electrolysis hydrogen production system.

[0073] This section describes the specific application environment architecture or hardware architecture that the startup method depends on. (References) Figure 1 , Figure 1 This is a schematic diagram of the architecture of a startup system provided in an embodiment of this application. Please refer to [link / reference]. Figure 1 The startup system includes a control unit, a self-test module, a current loading module, and a feedback module, among which:

[0074] The one-button start controller is integrated into the control unit, allowing users to start the water electrolysis hydrogen production system simply by clicking the one-button start controller.

[0075] The control unit is used to respond to the user's click on the one-button start controller and obtain the operating parameters and performance parameters of multiple electrolyzers in the water electrolysis hydrogen production system.

[0076] Control units include, for example, distributed control systems (DCS) and programmable logic controllers (PLCs).

[0077] The self-test module is used to determine whether each electrolyzer has met the start-up conditions based on the operating parameters of multiple electrolyzers.

[0078] The control unit is also used to obtain the available power capacity of the water electrolysis hydrogen production system.

[0079] The current loading module is used to start multiple electrolyzers in a water electrolysis hydrogen production system based on the performance parameters of multiple electrolyzers and the available power capacity of the power supply.

[0080] The feedback module is used to generate alarm prompts for the electrolytic cell.

[0081] The following explains the processing logic of the control unit:

[0082] In response to the user's click on the one-button start controller, the control unit acquires the operating and performance parameters of multiple electrolyzers in the water electrolysis hydrogen production system. Then, the control unit instructs the self-test module to determine whether each electrolyzer meets the start-up conditions based on the operating parameters. If at least one electrolyzer fails to meet the start-up conditions, the control unit instructs the feedback module to generate an alarm message corresponding to that at least one electrolyzer and stops starting the multiple electrolyzers in the water electrolysis hydrogen production system. When multiple electrolyzers meet the start-up conditions, the control unit acquires the available power capacity of the power supply for the water electrolysis hydrogen production system and instructs the current loading module to start the multiple electrolyzers based on the performance parameters and available power capacity of the power supply.

[0083] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0084] Figure 2 This is a flowchart illustrating a startup method provided in an embodiment of this application, as shown below. Figure 2 As shown, the method includes:

[0085] S201. Obtain the operating parameters and performance parameters of multiple electrolyzers in the water electrolysis hydrogen production system.

[0086] In this embodiment, the control unit responds to the user's click on the one-button start controller by acquiring the operating parameters and performance parameters of multiple electrolyzers in the water electrolysis hydrogen production system.

[0087] The operating parameters of the electrolytic cell include, but are not limited to: instrument air pressure, power supply status, rectifier communication status, safety instrumented system (SIS) interlock status, cell voltage, water and gas supply status, conductivity, leakage status, combustible gas concentration, smoke detection signal, and temperature monitoring value.

[0088] The performance parameters of an electrolyzer include, but are not limited to: energy consumption, hydrogen production efficiency, and equipment aging level.

[0089] Specifically, the control unit communicates with the sensors (such as pressure sensors, voltage sensors, and gas concentration sensors) of the electrolytic cell and the equipment controllers (such as rectifier controllers and water-gas valve group controllers) through an industrial communication bus. It can receive the raw signals output by the sensors and equipment controllers in real time and convert the raw signals into standardized operating parameters.

[0090] For example, the control unit communicates with the pressure sensor corresponding to the control loop of the electrolytic cell via an industrial communication bus, obtains the current signal output by the pressure sensor in real time, and converts the current signal into the instrument air pressure.

[0091] It should be noted that the acquisition of other operating parameters of the electrolytic cell follows the unified logic of "sensor / controller signal transmission → signal conversion". For specific acquisition methods, please refer to relevant technologies, which will not be elaborated here.

[0092] S202. Based on the operating parameters of multiple electrolytic cells, determine whether each electrolytic cell has met the start-up conditions.

[0093] In this embodiment of the application, the self-test module determines whether each electrolytic cell has met the start-up conditions based on the operating parameters of multiple electrolytic cells.

[0094] In some embodiments, for any one electrolytic cell, determining whether each electrolytic cell has met the start-up conditions based on the operating parameters of multiple electrolytic cells can be as follows:

[0095] Determine whether each operating parameter of the electrolytic cell meets the corresponding preset conditions;

[0096] When all operating parameters of the electrolytic cell meet the corresponding preset conditions, the electrolytic cell is determined to have reached the start-up condition.

[0097] If the electrolytic cell has operating parameters that do not meet the corresponding preset conditions, it is determined that the electrolytic cell has not met the start-up conditions.

[0098] For example, the preset condition for the instrument air pressure is: greater than or equal to 0.4 MPa and less than or equal to 0.6 MPa. Then, it is determined whether the instrument air pressure meets the corresponding preset condition: when the instrument air pressure is greater than or equal to 0.4 MPa and less than or equal to 0.6 MPa, it is determined that the instrument air pressure meets the corresponding preset condition; otherwise, it is determined that the instrument air pressure does not meet the corresponding preset condition.

[0099] It should be noted that the preset conditions for other operating parameters (such as power status, rectifier communication status, cell voltage, water and gas supply status, etc.) are consistent with the preset condition judgment logic of instrument air pressure. The preset conditions (numerical range or status requirements) are set only according to the parameter characteristics (such as pressure, voltage, concentration, status, etc.). The judgment process for each parameter will not be repeated here.

[0100] It should be noted that the preset conditions for each operating parameter are not fixed and can be flexibly set according to the actual application scenario. The following factors can be referenced when setting them: the rated design parameters of the electrolyzer (such as the rated range of the cell voltage and the standard water and gas supply pressure provided by the manufacturer), the safety regulations of the environment where the water electrolysis hydrogen production system is located (such as the combustible gas concentration limit must comply with relevant safety regulations), the operating load requirements (such as the threshold of parameters such as conductivity and temperature can be appropriately tightened when operating under high load), and the degree of equipment aging (such as the cell voltage deviation range can be appropriately adjusted for electrolyzers with severe aging). This application does not limit the specific values ​​of the preset conditions.

[0101] S203. When at least one electrolyzer fails to meet the start-up conditions, generate an alarm message corresponding to the at least one electrolyzer and stop starting multiple electrolyzers in the water electrolysis hydrogen production system. The alarm message includes the identifier of the electrolyzer, the abnormal operating parameters of the electrolyzer, and the handling prompts for the electrolyzer.

[0102] In this embodiment of the application, when at least one electrolyzer fails to meet the start-up conditions, the control unit instructs the feedback module to generate an alarm message and stop starting multiple electrolyzers of the water electrolysis hydrogen production system.

[0103] The identifier for an electrolytic cell is a unique number. Optionally, this identifier can be associated with the cell's physical location information within the system. For example, an electrolytic cell identified as B-03-02 indicates the second electrolytic cell in the third row of the north electrolysis zone, facilitating quick location by the user of electrolytic cells that have not yet met the start-up conditions.

[0104] Alarm messages can also include preset conditions corresponding to abnormal operating parameters.

[0105] In some embodiments, the feedback module can determine the characteristic description of the abnormal operating parameters based on the abnormal operating parameters of the electrolytic cell that has not met the start-up conditions and the preset conditions corresponding to the abnormal operating parameters; based on the characteristic description of the abnormal operating parameters, it can find the processing prompts for the electrolytic cell in the preset knowledge base.

[0106] The preset knowledge base includes characteristic descriptions of multiple abnormal operating parameters and corresponding relationships for multiple processing prompts for the electrolytic cell.

[0107] The following explanation uses the abnormal operating parameter of an electrolytic cell, specifically instrument air pressure, as an example to illustrate how to retrieve the appropriate handling prompts for the electrolytic cell from a pre-defined knowledge base based on the abnormal operating parameters of an electrolytic cell that have not met the start-up conditions, and the corresponding preset conditions for these abnormal operating parameters:

[0108] When the instrument air pressure is 0.32 MPa, and the preset condition for the instrument air pressure is greater than or equal to 0.4 MPa and less than or equal to 0.6 MPa, it can be determined that the instrument air pressure is less than the lower limit of the preset condition. Based on the fact that the instrument air pressure is less than the lower limit of the preset condition, the following processing prompts for the electrolytic cell are found in the preset knowledge base: check whether the pipeline is leaking and whether the air compressor output is abnormal.

[0109] Users can update the preset knowledge base through the control unit, adding feature descriptions of new abnormal operating parameters and corresponding processing prompts for the electrolytic cell.

[0110] S204. When multiple electrolyzers meet the start-up conditions, obtain the available power capacity of the power supply for the water electrolysis hydrogen production system, and start the multiple electrolyzers of the water electrolysis hydrogen production system based on the performance parameters of the multiple electrolyzers and the available power capacity of the power supply.

[0111] In this embodiment of the application, when multiple electrolyzers meet the start-up conditions, the control unit obtains the available power capacity of the power supply of the water electrolysis hydrogen production system, and instructs the current loading module to start the multiple electrolyzers of the water electrolysis hydrogen production system based on the performance parameters of the multiple electrolyzers and the available power capacity of the power supply.

[0112] In some embodiments, obtaining the available power capacity of the power source for the water electrolysis hydrogen production system includes:

[0113] Obtain power detection data of the power supply for the water electrolysis hydrogen production system;

[0114] Based on power detection data, the current available power capacity of the power supply for the water electrolysis hydrogen production system is determined.

[0115] In some embodiments, starting multiple electrolyzers in a water electrolysis hydrogen production system based on the performance parameters of multiple electrolyzers and the available power capacity of the power source can be understood as: starting multiple electrolyzers in a water electrolysis hydrogen production system in multiple batches based on the performance parameters of multiple electrolyzers and the available power capacity of the power source, wherein the number of electrolyzers to be started in each batch is equal, and the sum of the number of electrolyzers to be started in multiple batches is equal to the number of electrolyzers in the water electrolysis hydrogen production system.

[0116] Specifically, the number of batches is determined based on the available power capacity of the power source; the electrolyzers to be started for each batch are determined based on the efficiency parameters of multiple electrolyzers, where the efficiency parameters indicate the hydrogen production rate of the electrolyzers, and the efficiency parameters of the electrolyzers that are started first indicate a higher hydrogen production rate.

[0117] In this embodiment, the operating parameters and performance parameters of multiple electrolyzers in the water electrolysis hydrogen production system are acquired. Based on the operating parameters of the multiple electrolyzers, it is determined whether each electrolyzer meets the start-up conditions. When at least one electrolyzer fails to meet the start-up conditions, an alarm message corresponding to at least one electrolyzer is generated, and the start-up of multiple electrolyzers in the water electrolysis hydrogen production system is stopped. The alarm message includes the electrolyzer's identifier, abnormal operating parameters of the electrolyzer, and handling prompts for the electrolyzer. When multiple electrolyzers meet the start-up conditions, the available power capacity of the power supply for the water electrolysis hydrogen production system is acquired, and based on the performance parameters of the multiple electrolyzers and the available power capacity of the power supply, the multiple electrolyzers in the water electrolysis hydrogen production system are started. In the above method, by automatically collecting the operating parameters and performance parameters of multiple electrolyzers and combining the verification logic of the operating parameters, it is automatically determined whether each electrolyzer meets the start-up conditions, eliminating the need for manual parameter checking of each unit and significantly reducing the time consumed in the start-up phase of a large-scale PEM water electrolysis hydrogen production system.

[0118] Furthermore, by replacing manual subjective judgment and operation with automatic verification and judgment logic of operating parameters, the operating parameters of the electrolyzer can be accurately verified strictly according to preset conditions. This effectively avoids problems such as parameter omission, misjudgment or improper start-up timing that may occur in manual operation, and ensures the safety and reliability of the water electrolysis hydrogen production system during the start-up phase.

[0119] In addition, alarm messages containing identifiers, abnormal parameters, and processing prompts are generated for electrolytic cells that do not meet the start-up conditions, which can help users quickly locate and handle problems and improve the efficiency of troubleshooting start-up failures.

[0120] In some embodiments, the operating parameters include first-level parameters and second-level parameters.

[0121] Hereinafter, based on any of the above embodiments, by... Figure 3 For any given electrolytic cell, when the operating parameters include first-level and second-level parameters, further explanation is provided on determining whether each electrolytic cell meets the start-up conditions based on the operating parameters of multiple electrolytic cells.

[0122] Figure 3 A flowchart illustrating a method for determining electrolytic cell start-up conditions provided in this application embodiment is shown below. Figure 3 As shown, the method includes:

[0123] S301. Determine whether each first-level parameter in the operating parameters of the electrolytic cell meets the corresponding preset conditions.

[0124] If there is a first-level parameter that does not meet the corresponding preset condition, execute S302.

[0125] When each first-level parameter meets the corresponding preset condition, execute S303-S304.

[0126] The operating parameters of the electrolyzer are divided into first-level parameters and second-level parameters according to safety priority and necessity of start-up. The first-level parameters are the key parameters to ensure the core safety and basic operational feasibility of the electrolyzer during the start-up phase. Whether the corresponding preset conditions are met directly determines whether the start-up process can continue, and they have a higher priority than the second-level parameters. The second-level parameters are auxiliary parameters that affect the stable operation of the electrolyzer after start-up, and can be flexibly adjusted in combination with the first start-up priority of the water electrolysis hydrogen production system.

[0127] Level 1 parameters include, but are not limited to: instrument air pressure, power supply status, rectifier communication status, SIS interlock status, cell voltage, combustible gas concentration, smoke detection signal, and temperature monitoring value.

[0128] Second-level parameters include, but are not limited to: water and gas supply status, conductivity, and leakage status.

[0129] It should be noted that the process of determining whether each first-level parameter in the operating parameters of the electrolytic cell meets the corresponding preset conditions is similar to the process of determining whether the instrument air pressure meets the corresponding preset conditions in S202, and will not be repeated here.

[0130] S302. Determine that the electrolytic cell has not met the start-up conditions, and mark the first-level parameters that do not meet the corresponding preset conditions as abnormal operating parameters of the electrolytic cell.

[0131] Specifically, when the self-test module detects that any of the first-level parameters of the electrolytic cell does not meet the corresponding preset conditions, it determines that the electrolytic cell has not met the start-up conditions. The self-test module will mark all first-level parameters that do not meet the preset conditions as abnormal operating parameters of the electrolytic cell. In subsequent steps, the control unit instructs the feedback module to generate an alarm message indicating the abnormal operating parameters of the electrolytic cell.

[0132] S303, Obtain the first startup priority of the water electrolysis hydrogen production system.

[0133] Specifically, when the self-test module detects that all first-level parameters of the electrolyzer meet the corresponding preset conditions, it obtains the first start-up priority of the water electrolysis hydrogen production system, and then determines whether the electrolyzer has met the start-up conditions based on each second-level parameter and the first start-up priority.

[0134] In some embodiments, the first startup priority of the water electrolysis hydrogen production system includes: a first priority and a second priority, wherein the first priority is lower than the second priority.

[0135] The first priority indicates that the water electrolysis hydrogen production system is currently in a "stability-first" operation scenario. The core requirement is to ensure long-term stable hydrogen production after the electrolyzer is started, and to avoid operational failures or increased maintenance costs due to parameter deviations. The second priority indicates that the water electrolysis hydrogen production system is currently in an "emergency start-up" operation scenario. The core requirement is to respond quickly to hydrogen energy supply needs, and to allow for slight deviations in non-critical parameters without affecting core safety.

[0136] The first priority is lower than the second priority. This can be understood as the startup requirement corresponding to the second priority being more urgent than the startup requirement corresponding to the first priority.

[0137] In some embodiments, obtaining the first startup priority of the water electrolysis hydrogen production system can be achieved by: the control unit reading a preset configuration to obtain the first startup priority of the water electrolysis hydrogen production system, wherein the preset configuration is a fixed priority pre-set by the water electrolysis hydrogen production system according to the daily operation plan.

[0138] In some embodiments, obtaining the first startup priority of the water electrolysis hydrogen production system can also be: the control unit receives the first startup priority issued by the user, that is, the user issues the first startup priority based on the immediate hydrogen production demand through the one-click start controller or remote operation and maintenance platform integrated in the control unit.

[0139] Optionally, the first startup priority can be an integer; for example, 0 represents the first priority and 1 represents the second priority.

[0140] S304. Based on each second-level parameter and the first start-up priority, determine whether the electrolytic cell has met the start-up conditions.

[0141] In some embodiments, determining whether the electrolytic cell has met the startup conditions based on each second-level parameter and the first startup priority includes:

[0142] Determine the first startup priority for the water electrolysis hydrogen production system;

[0143] Determine whether each of the second-stage parameters of the electrolytic cell meets the corresponding preset conditions;

[0144] When each of the secondary parameters meets the corresponding preset conditions, the electrolytic cell is determined to have reached the start-up condition.

[0145] If there is a second-level parameter that does not meet the corresponding preset condition, if the first start priority is the first priority, it is determined that the electrolytic cell has not met the start condition; if the first start priority is the second priority, it is determined that the electrolytic cell has met the start condition, and an alarm message corresponding to the electrolytic cell is generated.

[0146] Determining the first startup priority of the water electrolysis hydrogen production system can be understood as determining whether the first startup priority of the water electrolysis hydrogen production system is the first priority or the second priority.

[0147] It should be noted that the process of determining whether each second-stage parameter of the electrolytic cell meets the corresponding preset conditions is similar to the process of determining whether the instrument air pressure meets the corresponding preset conditions in S202, and will not be repeated here.

[0148] In this embodiment, for any electrolyzer, it is determined whether each first-level parameter in the operating parameters meets the corresponding preset conditions. If there is a first-level parameter that does not meet the corresponding preset conditions, it is determined that the electrolyzer has not reached the start-up conditions, and the first-level parameter that does not meet the corresponding preset conditions is marked as an abnormal operating parameter of the electrolyzer. When each first-level parameter meets the corresponding preset conditions, the first start-up priority of the water electrolysis hydrogen production system is obtained. Based on each second-level parameter and the first start-up priority, it is determined whether the electrolyzer has reached the start-up conditions. In the above method, by dividing the operating parameters of the electrolyzer into first-level parameters and second-level parameters, and determining the start-up conditions according to the hierarchical logic, it is ensured that the start-up process can only proceed if the key safety indicators meet the standards. This avoids the core hidden dangers in the start-up stage from the source, and can balance start-up efficiency and operational stability according to actual operational needs (such as emergency hydrogen production and normal stable operation), making the start-up strategy more suitable for different application scenarios, and further improving the reliability and flexibility of the start-up process.

[0149] Hereinafter, based on any of the above embodiments, by... Figure 4 The paper further explains how to start up multiple electrolyzers in a water electrolysis hydrogen production system based on the performance parameters of multiple electrolyzers and the available power capacity of the power supply.

[0150] Figure 4 A flowchart illustrating a power efficiency adaptation startup method provided in this application embodiment is shown below. Figure 4 As shown, the method includes:

[0151] S401. Based on the available power capacity of the power supply, determine the first number of electrolytic cells that the power supply can currently start.

[0152] In some embodiments, based on the available power capacity of the power supply, a first number of electrolytic cells that the power supply can currently start is retrieved from a preset first correspondence. The first correspondence includes correspondences between the available power capacity of multiple power supplies and multiple first numbers. For example, the first correspondence is shown in Table 1:

[0153] Table 1

[0154] Available power capacity of the power supply First number Power 1 2 Power 2 3 Power 3 4 Power 4 5

[0155] For example, when the available power capacity of the power supply is power 1, it can be found from Table 1 that the first quantity is 2.

[0156] S402. Determine whether the first quantity is greater than or equal to the number of electrolytic cells.

[0157] If yes, execute S403; otherwise, execute S404.

[0158] S403. Start up multiple electrolytic cells.

[0159] In some embodiments, starting up a plurality of electrolytic cells includes:

[0160] The control power supply outputs variable current to multiple electrolytic cells based on a preset current curve. The variable current varies from the minimum operating current of the electrolytic cells to the target starting current of the electrolytic cells according to the preset current curve.

[0161] S404. Based on the performance parameters of multiple electrolytic cells, determine a first number of electrolytic cells among the multiple electrolytic cells, and start the first number of electrolytic cells.

[0162] In some embodiments, based on the performance parameters of multiple electrolytic cells, a first number of electrolytic cells are determined among the multiple electrolytic cells, including:

[0163] Based on the performance parameters of each electrolyzer, the second start-up priority of each electrolyzer is determined;

[0164] Based on the second start-up priority of each electrolytic cell, multiple electrolytic cells are sorted, and a first number of electrolytic cells are determined from the sorted multiple electrolytic cells.

[0165] The following examples, using the performance parameters of electrolyzers, including energy consumption, hydrogen production efficiency, and / or equipment aging, illustrate how to determine the second startup priority of an electrolyzer based on its performance parameters, through Examples 1A, 1B, and 1C:

[0166] Example 1A: When the performance parameters of an electrolyzer include hydrogen production efficiency, the higher the hydrogen production efficiency, the higher the second start-up priority of the electrolyzer. Therefore, the second start-up priority can be hydrogen production efficiency.

[0167] Example 1B: When the performance parameters of the electrolyzer include energy consumption or equipment aging degree, the higher the energy consumption or equipment aging degree, the lower the second start-up priority of the electrolyzer. Therefore, the second start-up priority can be the reciprocal of the energy consumption or equipment aging degree.

[0168] Example 1C: When the performance parameters of an electrolyzer include two or three of the following: energy consumption, hydrogen production efficiency, and equipment aging degree, the performance parameters of each electrolyzer can be normalized, and then the second start-up priority of each electrolyzer can be determined based on the normalized performance parameters of each electrolyzer.

[0169] The relationship between the normalized performance parameters and the second startup priority satisfies the following formula 1:

[0170] Formula 1;

[0171] in, Indicates the second boot priority. This represents the weight of the i-th performance parameter. Let N represent the i-th performance parameter after normalization, and N represent the number of performance parameters.

[0172] For example, the weight of energy consumption is -0.3, the weight of hydrogen production efficiency is 0.4, and the weight of equipment aging degree is -0.3.

[0173] Specifically, based on the second startup priority of each electrolytic cell, the multiple electrolytic cells are sorted from high to low, and the top 100 electrolytic cells are determined from the sorted multiple electrolytic cells.

[0174] In some embodiments, starting a first number of electrolytic cells includes:

[0175] The control power supply outputs a variable current to a first number of electrolytic cells based on a preset current curve. The variable current varies from the minimum operating current of the electrolytic cells to the target starting current of the electrolytic cells according to the preset current curve.

[0176] Optionally, the power supply can also: output a variable current to a first number of electrolytic cells based on a ramp function or a preset power curve, wherein the variable current varies from the minimum operating current of the electrolytic cells to the target starting current of the electrolytic cells according to a preset current curve.

[0177] In some embodiments, after starting a first number of electrolytic cells, the available power capacity of the power supply is re-determined, and the process of S401-S404 is repeated to determine the next batch of electrolytic cells that can be started, until all electrolytic cells have been started.

[0178] In this embodiment, a first number of electrolyzers that can be started by the power supply is determined based on the available power capacity. If the first number is greater than or equal to the number of electrolyzers, multiple electrolyzers are started. If the first number is less than the number of electrolyzers, a first number of electrolyzers are determined from among the multiple electrolyzers based on their efficiency parameters, and these first number of electrolyzers are started. In the above method, by first determining the first number of startable electrolyzers based on the available power capacity of the power supply, and then flexibly adjusting the start-up strategy by comparing the first number with the actual total number of electrolyzers, the power supply overload tripping caused by starting too many electrolyzers at once is avoided, ensuring the safety and stability of the power supply operation. Furthermore, when the power supply power is limited, electrolyzers with higher priority are selected based on efficiency parameters for priority start-up, ensuring maximum hydrogen production efficiency. At the same time, the logic of batch start-up adapts to different power supply scenarios, making the start-up process more flexible and practical, effectively improving the resource utilization and operational reliability of the water electrolysis hydrogen production system during the start-up phase.
