Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen energy technology, and relates to a modular skid-mounted hydrogen supply and hydrogen refueling station system integration and intelligent management method. Background Art

[0002] With the transformation of the global energy structure towards low-carbon and clean energy, hydrogen energy, as an efficient and zero-emission energy carrier, is gradually becoming an important development direction in the energy field. The application scenarios of hydrogen energy are continuously expanding, especially in the fields of transportation, industry, and energy storage. The demand for hydrogen fuel cell vehicles, hydrogen forklifts, and industrial hydrogen is growing rapidly. As a key infrastructure for hydrogen energy utilization, the construction and technical level of hydrogen refueling stations directly affect the improvement and popularization of the hydrogen energy industry chain. However, there are still many deficiencies in the current hydrogen refueling station technology in terms of design, operation, and management, making it difficult to meet the increasing diversified hydrogen demand.

[0003] Existing hydrogen refueling stations mostly adopt a fixed construction mode, usually including main components such as hydrogen storage tanks, compressors, hydrogen dispensers, and control systems. This design played a certain role in the early application of hydrogen energy, but its limitations have gradually emerged. First of all, the construction period of fixed hydrogen refueling stations is relatively long, usually taking several months to one year, and the floor area is relatively large, making it difficult to meet the requirements of rapid deployment. For example, in centralized hydrogen consumption scenarios such as industrial parks or logistics centers, the existing technology is difficult to achieve rapid installation and flexible expansion. Secondly, the hydrogen storage and supply systems perform poorly in the face of complex working conditions. Traditional hydrogen storage modules mostly adopt a single high-pressure storage tank design, lacking a dynamic adjustment mechanism. When the hydrogen supply flow fluctuates, the compressor needs to start and stop frequently to maintain pressure stability, which not only increases energy consumption but also accelerates equipment wear. In addition, the pipeline hydrogen supply system in the existing technology usually only has simple pressure sensors and manual valves, making it difficult to achieve precise control of hydrogen flow and pressure. Especially in high-demand scenarios such as supporting the durability experiments of hydrogen fuel cells or internal combustion engines, the system stability is insufficient.

[0004] In terms of intelligent management, the control technology of existing hydrogen refueling stations is also relatively primitive. At present, most hydrogen refueling stations rely on traditional PLC (Programmable Logic Controller) systems to perform basic adjustments on equipment such as compressors and valves through preset thresholds. However, this control method cannot adapt to the dynamic requirements under variable working conditions. For example, when there are various types of hydrogen-consuming equipment (such as forklifts, logistics vehicles, commuter vehicles) or the hydrogen pressure requirements vary greatly, the system is difficult to automatically adjust the filling pressure and requires manual intervention, resulting in low efficiency. At the same time, the existing technology lacks the ability of in-depth analysis in fault detection and early warning, mostly relying on simple threshold alarms, making it difficult to predict potential faults in advance or optimize operation parameters. This limits the operation safety and long-term stability of hydrogen refueling stations. Especially in high-load or extreme environments, the risk of equipment failure increases significantly.

[0005] In recent years, some technologies have attempted to improve hydrogen refueling stations. For example, the modular skid-mounted design has been proposed in the literature. By integrating functions such as hydrogen storage and hydrogen refueling on a movable skid-mounted platform, the construction period can be shortened. However, these designs still remain in the primary stage of module splicing, lacking specific technical solutions for quick connection and efficient assembly. Traditional flange connections are mostly used for the interfaces between modules, resulting in a long installation time and insufficient airtightness guarantee. In addition, some basic intelligent controls have been introduced in hydrogen refueling stations. For example, the valve opening is adjusted through a single-point pressure sensor and PID (Proportional-Integral-Derivative) control logic. However, this method is only applicable to a single stable working condition and cannot handle complex scenarios such as flow gradient changes or multi-device coordinated operation. In terms of compressor optimization, existing technologies mostly achieve frequency adjustment through frequency converters, but the adjustment logic is relatively simple and lacks the ability to analyze historical data and future trends, resulting in limited optimization effects.

[0006] At the same time, the application requirements of the hydrogen energy industry are developing towards diversification and high efficiency. Taking a green park as an example, hydrogen forklifts, logistics vehicles, and experimental equipment may be operating simultaneously inside, involving hydrogen demand in a wide pressure range from low pressure (0.1 MPa) to high pressure (12 MPa). The existing hydrogen refueling station designs are difficult to meet such differentiated requirements. Especially in the scenario of centralized hydrogen supply, the coordination between the hydrogen supply and hydrogen refueling systems is insufficient, making it difficult to support experiments and operations under complex working conditions. In addition, with the advancement of the standardization process of hydrogen energy technologies, the existing hydrogen refueling stations lack systematic technical means to support the formulation of specifications and cannot provide a reliable technical basis for industrial promotion.

[0007] In summary, the existing hydrogen refueling station technologies have obvious deficiencies in modular design, dynamic pressure regulation, pipeline hydrogen supply control, and intelligent management, and are difficult to meet the efficient, safe, and flexible requirements of centralized hydrogen consumption scenarios such as green parks. Therefore, there is an urgent need to develop a new type of hydrogen refueling station system. Through innovative hardware design and intelligent technical means, the limitations of existing technologies can be solved, the adaptability and operation efficiency of hydrogen supply and refueling can be improved, and technical support can be provided for the large-scale application of the hydrogen energy industry. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to solve the above problems and provide a method for system integration and intelligent management of a modular skid-mounted hydrogen supply and refueling station.

[0009] To achieve the above purpose, the present invention provides the following technical solutions:

[0010] A method for system integration and intelligent management of a modular skid-mounted hydrogen supply and refueling station, including:

[0011] (1) Construct a modular skid-mounted hydrogen supply and hydrogenation equipment system. The system includes a hydrogen supply module, a hydrogenation module, and a hydrogen storage module. Among them, the hydrogen storage module adopts a series structure of a high-pressure storage tank and a low-pressure buffer tank. A two-way dynamic pressure regulating valve is installed inside the buffer tank. The regulating valve adjusts the pressure inside the tank bidirectionally according to the fluctuation of the hydrogen supply flow through a spring-electromagnetic composite drive mechanism.

[0012] (2) Set up a pipeline hydrogen supply system. The system forms a closed-loop control circuit through a non-uniform multi-point pressure sensor array and an intelligent flow control valve group arranged along the pipeline. The sensor array adaptively adjusts the sampling frequency based on the flow gradient, and the control valve group adjusts the opening degree in real time through an improved PID control logic.

[0013] (3) Implement an intelligent management technology based on deep learning. Through an embedded controller, a double-layer adaptive full-condition optimization algorithm is run. The algorithm includes a load prediction layer based on a long short-term memory neural network (LSTM) and a frequency optimization layer based on reinforcement learning, dynamically adjusting the operating frequency of the compressor.

[0014] Furthermore, the hydrogen supply module adopts a linkage hydrogen supply mechanism between the tube bundle vehicle and the in-station hydrogen storage tank. Combined with the two-way dynamic pressure regulating valve, the regulating valve quickly switches through the spring-electromagnetic composite drive mechanism when the input flow fluctuates.

[0015] Furthermore, the non-uniform multi-point pressure sensor array includes at least 6 sensor nodes. The node spacing is dynamically designed according to the pipeline curvature and the flow change rate. The improved PID control logic adjusts the opening degree of the control valve group by introducing a flow acceleration compensation factor.

[0016] Furthermore, the double-layer adaptive full-condition optimization algorithm adjusts the operation of the compressor through the following steps:

[0017] (a) Collect the temperature, pressure, flow, and vibration data during the operation of the compressor to construct a four-dimensional condition feature matrix;

[0018] (b) Predict the load change trend within the next 10 minutes through the LSTM network;

[0019] (c) Optimize the combination of the compressor frequency and the valve opening degree according to the predicted trend through the reinforcement learning model.

[0020] Furthermore, the modular skid-mounted hydrogen supply and hydrogenation equipment system adopts a self-locking quick-install interface and a prefabricated module design. The self-locking interface connects each module through a combination of a wedge-shaped buckle and an airtight sealing ring.

[0021] Furthermore, it is characterized in that the hydrogenation module realizes wide-pressure-range filling through a multi-stage filling pressure distribution device. The device includes a high-pressure filling channel and a low-pressure filling channel. The channels automatically switch the filling pressure according to the requirements of the hydrogen-consuming equipment through a two-way switching valve.

[0022] Furthermore, the intelligent management technology integrates a fault self-diagnosis function. By analyzing the abnormal patterns of the sensor array and compressor operation data through an embedded controller, it predicts the fault probability based on the Bayesian network model and issues early warning signals.

[0023] Furthermore, through the collaborative action of the dynamic pressure regulating valve and the closed-loop control loop in the hydrogen supply module and the pipeline hydrogen supply system, the system supports the durability experiments of hydrogen fuel cells and internal combustion engines under complex working conditions.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. Quick deployment and flexible expansion

[0026] Adopting a self-locking quick-install interface and prefabricated module design, through the combined connection of wedge-shaped buckles and airtight sealing rings, compared with the flange connection method of traditional hydrogen refueling stations, the module installation time is significantly shortened. The construction of traditional fixed hydrogen refueling stations takes several months, while the present invention can shorten the construction period to several weeks through modular design, and at the same time supports flexible addition and subtraction of modules according to hydrogen demand, especially suitable for temporary or dynamic hydrogen use scenarios such as green parks, improving the deployment efficiency and adaptability of hydrogen refueling stations.

[0027] 2. Efficient hydrogen supply and pressure stability

[0028] The hydrogen storage module adopts a series structure of high-pressure storage tanks and low-pressure buffer tanks, combined with a two-way dynamic pressure regulating valve, and uses a spring-electromagnetic composite drive mechanism to achieve rapid pressure regulation. When the hydrogen supply flow fluctuates, the regulating valve can respond in real time, avoiding frequent start and stop of the compressor, and significantly improving the stability of the hydrogen supply system. Compared with the traditional single storage tank design, the present invention can smooth the pressure fluctuation under complex working conditions, ensure the continuity of hydrogen supply, and provide reliable support for downstream hydrogen refueling and experimental equipment.

[0029] 3. Precise flow and pressure control

[0030] The pipeline hydrogen supply system adopts a non-uniform multi-point pressure sensor array and an intelligent flow control valve group to form a closed-loop control loop. The sensor array adaptively adjusts the sampling frequency according to the flow gradient, and combines an improved PID control logic to introduce a flow acceleration compensation factor to achieve dynamic and precise regulation of hydrogen flow and pressure. Compared with the single-point sensor and simple valve control in the prior art, the present invention can adapt to changing working conditions, ensure the efficiency and consistency of pipeline hydrogen supply, and is especially suitable for high-precision demand scenarios such as hydrogen fuel cell durability experiments.

[0031] 4. Intelligent operation optimization

[0032] Through a double-layer adaptive full-condition optimization algorithm based on deep learning, the LSTM network is used to predict the load change trend and combined with reinforcement learning to optimize the compressor frequency and valve opening, significantly improving the operating efficiency of the system. Traditional hydrogen refueling stations mostly rely on fixed threshold control and are difficult to cope with dynamic loads. However, through the intelligent analysis of historical data and real-time operating conditions, the present invention can adjust the operating parameters of equipment in advance, reduce energy consumption and extend the equipment life, providing an efficient management means for centralized hydrogen supply scenarios.

[0033] 5. Adaptability to wide pressure range refueling

[0034] The hydrogen refueling module is equipped with a multi-stage refueling pressure distribution device, with high-pressure and low-pressure refueling channels, and automatically switches the refueling pressure through a two-way switching valve, capable of meeting the wide pressure range requirements from 0.1 MPa to 12 MPa. Compared with traditional single-pressure refueling systems, the present invention supports the differentiated refueling needs of various equipment such as hydrogen forklifts, logistics vehicles, and commuter vehicles, improving the versatility and service capacity of hydrogen refueling stations.

[0035] 6. Safety guarantee and fault prevention

[0036] The intelligent management technology integrates a fault self-diagnosis function. By analyzing the abnormal patterns of the sensor array and compressor operation data through an embedded controller, it predicts the fault probability based on the Bayesian network model and issues a warning signal. Compared with the simple threshold alarm in the prior art, the present invention can identify potential faults in advance, improve the operating safety of the system, and provide technical support for high-reliability scenarios such as green parks.

[0037] 7. Support for complex working condition experiments

[0038] Through the coordinated action of the dynamic pressure regulating valve and the closed-loop control loop, the system can support the durability experiments of hydrogen fuel cells and internal combustion engines under complex working conditions. Traditional hydrogen refueling stations are difficult to maintain stability in the face of the highly fluctuating hydrogen demand of experimental equipment. However, through the integration of multi-level technical means, the present invention ensures the continuity and reliability of the experimental process, providing important support for hydrogen energy technology research and development.
