[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] The invention provides an efficiency-optimizing operation control system for a hydrogen production device. Figure 1 Schematic diagram of the structure of the efficiency optimization operation control system of the hydrogen production device provided by the present invention, such as Figure 1 As shown, the system includes:
[0038] The electric quantity measurement module 101 is used to detect the voltage and current of the hydrogen production device;
[0039] A hydrogen measurement module 102, used to detect the hydrogen mass flow rate of the electrolyzer connected to the hydrogen production device;
[0040] The calculation and analysis module 103 is used to optimize the reference efficiency curve based on the voltage, current and hydrogen mass flow rate to obtain an optimized efficiency curve;
[0041] The operation control module 104 is used to control the operation of the hydrogen production device based on the optimized efficiency curve.
[0042] like Figure 1 As shown, the power measurement module 101 can be connected to the power distribution cabinet and the power supply of the hydrogen production device, and can be used to detect the voltage and current on the AC side and the DC side of the hydrogen production device. The detected voltage and current are provided to the calculation and analysis module 103 for electric power calculation.
[0043] The hydrogen measurement module 102 is connected to the electrolyzer of the hydrogen production device. Since the function of the electrolyzer is to electrolyze water into hydrogen and oxygen, the hydrogen measurement module 102 connected to the electrolyzer can detect the hydrogen mass flow rate, and the detected hydrogen mass flow rate is used to provide the calculation and analysis module 103 to calculate the hydrogen production amount. Among them, the hydrogen mass flow rate refers to the mass of hydrogen passing through the pipeline cross section per unit time.
[0044] After the current measurement module 101 detects the voltage and current, and the hydrogen measurement module 102 detects the hydrogen mass flow rate, the calculation and analysis module 103 can determine the input electric power and the output electric power based on the voltage and the current, and then determine the electric power efficiency according to the input electric power and the output electric power. At the same time, the calculation and analysis module 103 can determine the amount of hydrogen produced according to the hydrogen mass flow rate. In addition, the reference efficiency curve is a relationship curve between the electric power efficiency of the hydrogen production device and the amount of hydrogen produced. Under normal circumstances, the reference efficiency curve of the hydrogen production device is nonlinear, that is, as the amount of hydrogen produced increases, its electric power efficiency will also increase accordingly.
[0045] In addition, the efficiency curve of the hydrogen production device is affected by many factors, including the purity of the reactants, reaction temperature, pressure, catalyst type and quality, etc. Generally speaking, when the reaction temperature and pressure increase, the efficiency of the hydrogen production device will increase, because high temperature and high pressure can increase the reaction rate and the separation rate of the reaction products. However, when the temperature and pressure exceed a certain range, the efficiency will be reduced, because excessive reaction conditions will lead to side reactions, thereby reducing the production of hydrogen. In other words, the corresponding efficiency curve of the hydrogen production device may be different when it is under different operating conditions. However, the reference efficiency curve is usually the efficiency curve of the hydrogen production device set according to standard operating conditions. For non-standard operating conditions, it cannot accurately reflect the relationship between the electrical power efficiency of the hydrogen production device and the amount of hydrogen produced.
[0046] In this regard, the embodiment of the present invention can optimize the reference efficiency curve according to the electric power efficiency and hydrogen production amount calculated by the calculation and analysis module 103 to obtain an optimized efficiency curve. For example, the actual efficiency of the hydrogen production device can be calculated based on the electric power efficiency and hydrogen production amount calculated by the calculation and analysis module 103, and the reference electric power efficiency corresponding to the hydrogen production amount obtained by the calculation and analysis module 103 can be found in the reference efficiency curve, and the reference efficiency can be determined based on the reference electric power efficiency and hydrogen production. If the actual efficiency is greater than the reference efficiency, the reference efficiency curve can be updated with the calculated electric power efficiency to obtain an optimized efficiency curve.
[0047] After obtaining the optimized efficiency curve, the operation of the hydrogen production device can be controlled based on the optimized efficiency curve to make the hydrogen production device operate at the optimal efficiency. For example, the hydrogen production amount at time k and time k+1 can be determined based on the optimized efficiency curve, and the electric power efficiency corresponding to the hydrogen production amount with a larger hydrogen production amount is used as the electric power efficiency at time k+2, that is, the hydrogen production device is operated at the best efficiency under variable power.
[0048] It can be seen that the efficiency optimization operation and control system of the hydrogen production device provided in the embodiment of the present invention, by adding an electricity measurement module 101, a hydrogen measurement module 102, a calculation and analysis module 103 and an operation control module 104, can control the operation of the hydrogen production device based on the optimized efficiency curve without changing the original hydrogen production device and the hydrogen production process, thereby ensuring that the hydrogen production device can operate at the best efficiency, thereby reducing the loss in the hydrogen production process and thus reducing the production cost.
[0049] Based on the above embodiment, the system further includes a data preprocessing module 105;
[0050] The data preprocessing module 105 is used to filter the voltage and current sent by the electric quantity measurement module 101 and the hydrogen mass flow sent by the hydrogen measurement module 102 , and send the filtered data to the calculation and analysis module 103 .
[0051] Specifically, after receiving the voltage and current sent by the power measurement module 101 and the hydrogen mass flow rate sent by the hydrogen measurement module 102, the data preprocessing module 105 filters the voltage, current and hydrogen mass flow rate to remove data noise, and then the calculation and analysis module 103 can accurately optimize the reference efficiency curve based on the filtered data and obtain the optimized efficiency curve.

[0054] The first calculation module is used to determine the input electric power based on the input voltage and the input current;
[0055] The second calculation module is used to determine the output electric power based on the output voltage and the output current;
[0056] The third calculation module is used to determine the hydrogen production amount of the hydrogen production device based on the hydrogen mass flow rate;
[0057] The analysis module is used to optimize the reference efficiency curve based on the input electric power, the output electric power and the hydrogen production amount of the hydrogen production device to obtain the optimized efficiency curve.
[0058] Specifically, the input electric power refers to the electric power obtained from the power supply of the hydrogen production device, which represents the power conversion efficiency from the power supply to the load in the circuit, that is, the ratio of the useful power provided by the power supply to the load to the total input power. Optionally, the input electric power can be calculated with the input voltage and the input current, such as input electric power = input voltage × input current.
[0059] Output power refers to the actual output power of the circuit, which represents the ratio of the useful power provided by the circuit to the load to the total output power, that is, the actual energy conversion efficiency of the circuit to the load. Optionally, the output power can be calculated with the output voltage and the output current, such as output power = output voltage × output current.
[0060] After obtaining the input power and output power, the power efficiency η(k) per unit hydrogen production under variable power can be determined based on the following formula:
[0061]
[0062] Among them, P out (k) represents the output power, P in (k) represents the input electric power.
[0063] In addition, the hydrogen mass flow rate refers to the mass of hydrogen passing through the gas pipeline per unit time, and the hydrogen production amount refers to the mass of hydrogen produced by the water electrolysis method. Optionally, the hydrogen production amount can be determined by the product of the hydrogen mass flow rate, the hydrogen density and the heat of vaporization of water.
[0064] After obtaining the electric power efficiency and the amount of hydrogen produced, the reference efficiency curve can be optimized based on the electric power efficiency and the amount of hydrogen produced to obtain an optimized efficiency curve. For example, the actual efficiency of the hydrogen production device can be calculated based on the electric power efficiency and the amount of hydrogen produced, and the reference electric power efficiency corresponding to the amount of hydrogen produced can be found in the reference efficiency curve, and the reference efficiency can be determined based on the reference electric power efficiency and the amount of hydrogen produced. If the actual efficiency is greater than the reference efficiency, the reference efficiency curve can be updated with the calculated electric power efficiency to obtain an optimized efficiency curve.
[0065] Based on any of the above embodiments, the input electric power includes the input active power on the AC side and the input active power on the DC side, and the output electric power includes the output active power on the AC side and the output active power on the DC side.
[0066] Specifically, the AC side active power includes the AC side input active power and the AC side output active power. The AC side active power refers to the part of the AC circuit output by the power supply that can be consumed by the load and generate useful power.
[0067] The active power on the DC side includes the active power output on the AC side and the active power output on the DC side. The active power on the DC side refers to the part of the power supply output in the DC circuit that can be consumed by the load and generate useful power.
[0068] Based on any of the above embodiments, the operation control module 104 includes a hydrogen production amount calculation module and a control module;
[0069] The hydrogen production amount calculation module is used to determine the hydrogen production amount at time k based on the electric power efficiency at time k and the current increment at time k; determine the hydrogen production amount at time k+1 based on the electric power efficiency at time k+1 and the current increment at time k+1; the electric power efficiency at time k is determined based on the input electric power at time k and the output electric power at time k, and the electric power efficiency at time k+1 is determined based on the input electric power at time k+1 and the output electric power at time k+1;
[0070] The control module is used to determine the electric power efficiency of the hydrogen production device at time k+2 based on the hydrogen production amount at time k and the hydrogen production amount at time k+1, and control the operation of the hydrogen production device based on the electric power efficiency at time k+2.
[0071] The control module is specifically used for:
[0072] When the amount of hydrogen produced at time k is less than the amount of hydrogen produced at time k+1, the electric power efficiency at time k+1 is used as the electric power efficiency at time k+2, and the operation of the hydrogen production device is controlled based on the electric power efficiency at time k+2;
[0073] When the hydrogen production amount at time k is greater than the hydrogen production amount at time k+1, the electric power efficiency at time k is used as the electric power efficiency at time k+2, and the operation of the hydrogen production device is controlled based on the electric power efficiency at time k+2.
[0074] Optionally, the operation control module 104 may control the operation of the hydrogen production device based on the optimization efficiency curve according to the following formula:
[0075]
[0076] Wherein, k represents the control period of the hydrogen production device, H(k) represents the hydrogen production at time k, and I k represents the current at time k, ΔI k represents the current increment at time k, η(k) represents the electric power efficiency at time k, T s represents the duration of the sth control cycle of the hydrogen production device, H(k+1) represents the hydrogen production at time k+1, and I k+1 represents the current at time k+1, ΔI k+1 represents the current increment at time k+1, η(k+1) represents the electric power efficiency at time k+1, and η(k+2) represents the electric power efficiency at time k+2.
[0077] The following is a description of the efficiency optimization operation control method for a hydrogen production device provided by the present invention. The efficiency optimization operation control method for a hydrogen production device described below and the efficiency optimization operation control device for a hydrogen production device described above can be referenced to each other.
[0078] Based on any of the above embodiments, the present invention further provides a method for controlling the efficiency optimization operation of a hydrogen production device based on the efficiency optimization operation control system of the hydrogen production device as described in any of the above embodiments, the method comprising:
[0079] Step 210, detecting the voltage and current of the hydrogen production device;
[0080] Step 220, detecting the hydrogen mass flow rate of the electrolyzer connected to the hydrogen production device;
[0081] Step 230: Optimize the reference efficiency curve based on the voltage, current and hydrogen mass flow rate to obtain an optimized efficiency curve;
[0082] Step 240: Control the operation of the hydrogen production device based on the optimized efficiency curve.
[0083] like Figure 2 As shown, the electric quantity measurement module 101 can be used to detect the voltage and current of the AC side and the DC side of the hydrogen production device, and the detected voltage and current are provided to the calculation and analysis module 103 for electric power calculation. The hydrogen measurement module 102 is used to detect the hydrogen mass flow rate, and the detected hydrogen mass flow rate is provided to the calculation and analysis module 103 for hydrogen production calculation. The hydrogen mass flow rate refers to the mass of hydrogen passing through the pipeline cross section per unit time.
[0084] After the voltage and current are detected, and the hydrogen mass flow rate is detected, the voltage, current and hydrogen mass flow rate can be uploaded to the data preprocessing module 105, and the data preprocessing module 105 performs filtering processing and sends it to the calculation and analysis module 103, so that the calculation and analysis module 103 can determine the input electric power and the output electric power based on the voltage and current, and then determine the electric power efficiency according to the input electric power and the output electric power. At the same time, the calculation and analysis module 103 can determine the amount of hydrogen produced according to the hydrogen mass flow rate. In addition, the reference efficiency curve is a relationship curve between the electric power efficiency of the hydrogen production device and the amount of hydrogen produced. Under normal circumstances, the reference efficiency curve of the hydrogen production device is nonlinear, that is, as the amount of hydrogen produced increases, its electric power efficiency will also increase accordingly.
[0085] In addition, the efficiency curve of the hydrogen production device is affected by many factors, including the purity of the reactants, reaction temperature, pressure, catalyst type and quality, etc. Generally speaking, when the reaction temperature and pressure increase, the efficiency of the hydrogen production device will increase, because high temperature and high pressure can increase the reaction rate and the separation rate of the reaction products. However, when the temperature and pressure exceed a certain range, the efficiency will be reduced, because excessive reaction conditions will lead to side reactions, thereby reducing the production of hydrogen. In other words, the corresponding efficiency curve of the hydrogen production device may be different when it is under different operating conditions. However, the reference efficiency curve is usually the efficiency curve of the hydrogen production device set according to standard operating conditions. For non-standard operating conditions, it cannot accurately reflect the relationship between the electrical power efficiency of the hydrogen production device and the amount of hydrogen produced.
[0086] In this regard, the embodiment of the present invention can optimize the reference efficiency curve according to the electric power efficiency and hydrogen production amount calculated by the calculation and analysis module 103 to obtain an optimized efficiency curve. For example, the actual efficiency of the hydrogen production device can be calculated based on the electric power efficiency and hydrogen production amount calculated by the calculation and analysis module 103, and the reference electric power efficiency corresponding to the hydrogen production amount obtained by the calculation and analysis module 103 can be found in the reference efficiency curve, and the reference efficiency can be determined based on the reference electric power efficiency and hydrogen production amount. If the actual efficiency is greater than the reference efficiency, the reference efficiency curve can be updated with the calculated electric power efficiency to obtain an optimized efficiency curve; if the actual efficiency is less than or equal to the reference efficiency, the detection voltage, current and hydrogen mass flow rate are returned.
[0087] After obtaining the optimized efficiency curve, the operation of the hydrogen production device can be controlled based on the optimized efficiency curve to make the hydrogen production device operate at the optimal efficiency. For example, the hydrogen production amount at time k and time k+1 can be determined based on the optimized efficiency curve, and the electric power efficiency corresponding to the hydrogen production amount with a larger hydrogen production amount is used as the electric power efficiency at time k+2, that is, the hydrogen production device is operated at the best efficiency under variable power.
