Description

Technical Field

[0001] The invention relates to the technical field of electrochemical energy storage, in particular to a fuel cell power system for airships based on flexible photovoltaic hydrogen production and a monitoring method. Background Art

[0002] Hydrogen is recognized as the cleanest fuel because its combustion product is water. If green electricity generated by photovoltaic solar energy is used to produce hydrogen, then both the production and use processes can be clean. Fuel cells can directly convert the chemical energy of fuel into electrical energy. This conversion technology, combined with green electricity hydrogen production technology generated by photovoltaic solar energy, has been applied to the use of airships. The technical process is to decompose the water generated by the fuel cell reaction into hydrogen and oxygen through electrolysis, and then input the hydrogen and oxygen into the fuel cell to generate electricity, thereby providing power for the airship. Hydrogen is not only the most basic and important fuel for fuel cells, but also an indispensable intermediary for realizing electrochemical reactions. During the continuous high-altitude flight, the airship needs to continuously obtain hydrogen for the power output of the fuel cell, and the obtained hydrogen and hydrogen density will change with the flight altitude of the airship. The difference in the amount of hydrogen obtained and the density of hydrogen will affect the flight safety of the airship. In the existing technical research on the flight safety of airships, the application document with application number CN201710570241.3 provides a hydrogen fuel cell system based on solar photovoltaic hydrogen production and a power generation method thereof, which can maximize the power generation capacity of the photovoltaic system on the airship by converting the current; another application document with application number CN201910909419.1 provides a photovoltaic and fuel cell integrated power generation system based on photovoltaic hydrogen production and energy storage, which uses photovoltaic hydrogen production and energy storage as the energy storage link, stores excess energy by electrolyzing water to produce hydrogen, converts the stored hydrogen into electrical energy through fuel cells, and even supplies power to the load together with the power grid, thereby ensuring the continuity of the system power supply and improving the utilization rate of solar energy. However, the designs of airships vary, and during the actual flight of an airship, the technical solution of the above-mentioned technical application cannot predict and analyze the amount of photovoltaic hydrogen production that can be obtained under different light intensities, and thus cannot determine the amount of hydrogen replenishment for the fuel cell. Due to the changes in air pressure that the airship is subjected to in the air, and due to the friction between the airship and the air during its continuous flight, hydrogen will continue to leak. Therefore, if the amount of photovoltaic hydrogen production that can be obtained under different light intensities cannot be predicted, it will have an adverse effect on the power output of the fuel cell, and thus endanger the flight safety of the airship. Summary of the invention

[0003] In view of the above problems existing in the technical field of existing electrochemical energy storage, the present invention is proposed.

[0004] Therefore, one of the purposes of the present invention is to provide a fuel cell power system and monitoring method for airships based on flexible photovoltaic hydrogen production, which calculates the amount of photovoltaic hydrogen production that can be obtained by the airship under different light intensities, and calculates the amount of hydrogen required for the airship fuel cell power output. In this way, the amount of photovoltaic hydrogen production that can be obtained under different environmental conditions in the future can be predicted, and the amount of hydrogen required for the airship fuel cell power output can be predicted, so as to ensure the sustainable and safe flight of the airship.

When the required and / or preset fuel cell power output value of the flight altitude matching the flight route is greater than the difference in the obtained hydrogen production to the power output of the preset airship fuel cell, the system issues an early warning.

[0019] As a preferred solution of the present invention, the amount of hydrogen consumed by the preset airship in a unit time period is collected based on the molar flow rate, including collecting the amount of hydrogen consumed every 3 to 5 minutes as a unit time period, and the flight time that the fuel cell of the preset airship can continue under the preset power output value is calculated based on the collected hydrogen consumption, and the calculation is obtained according to the following formula:

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0040] Since the existing technology cannot predict and analyze the amount of photovoltaic hydrogen production that can be obtained under different light intensities, and thus cannot determine the amount of hydrogen replenishment for the fuel cell, the air pressure changes that the airship is subjected to in the air, and the friction between the airship and the air during continuous flight will cause hydrogen to continuously leak. Therefore, if the amount of photovoltaic hydrogen production that can be obtained under different light intensities cannot be predicted, it will have an adverse effect on the power output of the fuel cell, and thus endanger the flight safety of the airship.

[0041] Based on this, the present invention proposes a fuel cell power system and monitoring method for airships based on flexible photovoltaic hydrogen production. By calculating the amount of photovoltaic hydrogen production that the airship can obtain under different light intensities, and by calculating the amount of hydrogen required for the airship fuel cell power output, the system can predict the amount of photovoltaic hydrogen production that can be obtained under different environmental conditions in future time periods, and at the same time predict the amount of hydrogen required for the airship fuel cell power output, so as to ensure the sustainable and safe flight of the airship.

[0042] The present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0043] Reference Figure 1 to Figure 2 , is an embodiment of the present invention, which provides a fuel cell power system for airships based on flexible photovoltaic hydrogen production, including:

[0044] The information acquisition module 110 is used to acquire the hull structure, flight route planning and flight positioning data of the preset airship, and acquire the environmental condition information of the planned flight route based on the planned flight route;

[0045] It should be noted that in this embodiment, the hull structure includes the design capacity of the airship and the sealing performance of the hull and the materials used, the environmental condition information includes the sun angle, wind direction, wind force, cloud height and precipitation of the flight route, and the information acquisition module includes GPS and / or Beidou satellite navigation positioning device;

[0046] It should be further explained that the environmental condition information obtained above is sent to the preset airship using ground equipment plus wireless communication network. It can also be realized by installing special equipment and / or sensors on the preset airship for real-time collection and processing, and the function of this module is realized. A hardware carrier is required, which includes wireless network transmission hardware equipment, sensors or special collection equipment, including special controllers and / or industrial computer computing equipment, and corresponding software algorithm support;

[0047] The design experience of airships shows that the capacity of the hull directly determines the maximum amount of hydrogen it can carry, which is a factor that has been determined in the design stage. The sealing performance of the airship is crucial to maintaining the amount of hydrogen inside. Good sealing performance can reduce hydrogen leakage and thus maintain the buoyancy of the airship.

[0048] A light intensity estimation module 120, which responds to the environmental condition information acquired by the information acquisition module, collects data features in the environmental condition information, and estimates the light intensity along the flight route;

[0049] The hydrogen production estimation module 130 is used to calculate the light intensity of the preset airship on the planned flight route to calculate the hydrogen production of photovoltaic power generation, and analyze and calculate the correlation characteristics between the obtained hydrogen volume and the light intensity along the flight route, and divide the correlation characteristics;

[0050] The classification of associated features includes air pressure and temperature;

[0051] The power analysis unit 140 responds to the light intensity obtained by the hydrogen production estimation module 130 on the preset airship in the planned route, and is used to analyze the power intensity that the hydrogen production obtained corresponding to the light intensity can provide to the fuel cell. The power analysis unit includes a power demand prediction module 1401 and a hydrogen consumption prediction module 1402;

[0052] The power demand prediction module 1401 is used to predict the power demand required at each moment during the entire flight process of the airship according to the known environmental conditions information on the planned route;

[0053] It should be emphasized in this embodiment that based on the power output change, the minimum power output data change, the maximum power output data change and the average power output data change of the fuel cell of the preset airship at the corresponding hydrogen production amount in the future period are collected, and the minimum power output data change, the maximum power output data change and the average power output data change are uploaded to the prediction model, and the Q-learning algorithm is used for reinforcement learning to optimize the prediction model;

[0054] It should be noted that in order to balance the complexity of the prediction model, the requirements of computing power, and the prediction accuracy, this embodiment decomposes the power demand P of the entire navigation process into power demands p1, p2, p3, ..., p in a continuous time window. n , where n represents the nth power demand, and the net output power of the fuel cell system must not be less than p in the corresponding time window. i , where i = 1, 2, 3, ..., n;

[0055] The hydrogen consumption prediction module 1402 is used to derive the hydrogen consumption for flight according to the power demand required by the airship;

[0056] The energy management and arbitration module 150 is used to compare and analyze the hydrogen production amount and the hydrogen consumption to determine whether the hydrogen production speed meets the required power demand;

[0057] It should be noted that the power system of the entire preset airship is a capacitive coupling system, and since it also includes a hydrogen production system, it forms a complex multi-domain coupling system, so the working status of each subsystem can be coordinated. For example, since the hydrogen production system consumes energy, the hydrogen production efficiency is different under different lighting conditions, so it can be selected whether to prioritize hydrogen production or use the electric energy stored in the fuel cell to drive the airship to fly, which improves flexibility.

[0058] A data and safety monitoring unit 160, used to obtain and process real-time data during flight;

[0059] It should be noted that in this embodiment, the real-time data includes fuel cell system operation data, photovoltaic power generation system operation data and hydrogen production system operation data;

[0060] Specifically, this embodiment is used to correct the prediction results of other modules to avoid risks caused by model errors, and at the same time independently monitor and verify the rationality of important output results of other modules to achieve safety redundancy;

[0061] Specifically, this embodiment further includes monitoring the change of hydrogen production data obtained by the preset airship in the preset region on a quarterly basis;

[0062] This embodiment also includes calculating the change difference of the preset airship fuel cell power output based on the minimum power output data change, the maximum power output data change and the power output average data change, analyzing the correlation between the change difference of the fuel cell power output and the hydrogen production amount, and generating a data model, and at the same time obtaining the fuel cell power output value required and / or preset for the preset airship on the planned flight route. When the fuel cell power output value required and / or preset for the flight altitude matching the planned flight route is greater than the change difference of the obtained hydrogen production amount to the preset airship fuel cell power output, the system issues an early warning;

[0063] At the same time, this embodiment collects the amount of hydrogen consumed by the preset airship in a unit time period based on the molar flow rate, including collecting the amount of hydrogen consumed every 3 to 5 minutes as a unit time period, and calculates the flight time that the fuel cell of the preset airship can continue under the preset power output value based on the collected hydrogen consumption, and calculates it according to the following formula:

[0064] in, is the hydrogen consumption;

[0065] In the formula, represents the molar mass of hydrogen, T is the power output consumption of the fuel cell when one hydrogen is consumed, is the amount of hydrogen produced per second, in moles, and the amount of hydrogen produced per second is the amount of hydrogen obtained when corresponding to the preset airship flight altitude and route;

[0066] On the basis of the above, this embodiment adopts the Monte Carlo method to sample the amount of hydrogen obtained by the preset airship at the preset flight altitude and route in a unit period of one minute, and to count the amount of photovoltaic hydrogen production obtained in a sampling period of ten minutes. The statistical reference object is the photovoltaic hydrogen production obtained in the first unit period. Based on the photovoltaic hydrogen production, when the photovoltaic hydrogen production obtained in the ten unit periods does not match the total amount of hydrogen obtained in the sampling period, the system determines that the photovoltaic system carried by the preset airship is in a fault state, otherwise, it is not determined;

[0067] In this embodiment, when the system determines that the photovoltaic system carried by the preset airship is in a fault state, the five hydrogen production data with the largest number of occurrences are collected in ten unit time periods, and the hydrogen production data are divided into five evaluation indicators, and the weights of the five evaluation indicators are calculated in the hydrogen production data collected in the next ten unit time periods.

[0068] Based on the above, the present application can predict the amount of photovoltaic hydrogen production that can be obtained under different environmental conditions in the future period by calculating the amount of photovoltaic hydrogen production that can be obtained by the airship under different light intensities, and by calculating the amount of hydrogen required for the airship fuel cell power output. At the same time, it predicts the amount of hydrogen required for the airship fuel cell power output to ensure the sustainable and safe flight of the airship.

[0069] This embodiment combines the above-mentioned fuel cell power system for airship based on flexible photovoltaic hydrogen production, and also proposes a monitoring method of the system, as follows:

[0070] S10: obtaining a preset airship hull structure, a flight route plan, and flight positioning data of the airship, and obtaining environmental condition information of the planned flight route based on the planned flight route;

[0071] S20: Collect data features in the environmental condition information and estimate the light intensity along the flight route;

[0072] S30: calculating the light intensity of the preset airship on the planned flight route to calculate the amount of hydrogen produced by photovoltaic power generation, and analyzing and calculating the correlation characteristics between the amount of hydrogen obtained and the light intensity along the flight route, and dividing the correlation characteristics;

[0073] S40: Analyzing the power intensity that can be provided by the fuel cell based on the amount of hydrogen produced corresponding to the light intensity according to the light intensity obtained by the preset airship on the planned route;

[0074] S50: predicting the power demand of the airship at each moment during the entire flight process according to known environmental condition information on the planned route, and deriving the hydrogen consumption for flight according to the power demand of the airship;

[0075] S60: Compare and analyze the hydrogen production amount and the hydrogen consumption to determine whether the hydrogen production speed meets the required power demand;

[0076] S70: Acquire and process real-time data during flight.

[0077] In summary, the present invention calculates the amount of hydrogen produced by photovoltaic power generation that can be obtained by the airship under different light intensities, and calculates the amount of hydrogen consumed by the airship fuel cell power output, so that the airship can predict the amount of hydrogen produced by photovoltaic power generation that can be obtained under different environmental conditions in the future period, and at the same time predict the amount of hydrogen consumed by the airship power output under different environmental conditions. In addition, the present invention can also calculate the power output value that can be provided by the remaining hydrogen according to the flight environment of the airship and / or the preset fuel cell power output value. When the fuel cell power output that can be provided by the calculated remaining hydrogen is insufficient, the system issues an early warning to ensure the sustainable and safe flight of the airship.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
