Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power generation, in particular to a multifunctional and efficient SOFC power generation management method and system for islands. BACKGROUND

[0002] Power generation refers to the process of converting various forms of energy (such as heat energy, mechanical energy, electrical energy, light energy, chemical energy, etc.) existing in nature into electrical energy through specific technical means.

[0003] Currently, when generating power on islands, diesel generators are generally used to generate power. The diesel generator burns diesel, releases energy after burning diesel, and drives the rotor of the diesel generator to rotate, thereby converting chemical energy into mechanical energy and then into electrical energy, ultimately achieving power generation.

Attached Figure Description

[0080] Figure 1 This is a flowchart of a method for managing multifunctional and efficient SOFC power generation on islands. Detailed Implementation

[0081] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0082] A multifunctional and efficient SOFC power generation management method for islands collects and analyzes heating parameter information, temperature detection values, mixing information, current time point, island location, pure water production, and residual heat generated during power generation. This data is then used to determine intake control information and gas supply adjustment information, thereby precisely controlling the SOFC stack for power generation and reducing air pollution generated during island power generation.

[0083] Reference Figure 1 This invention discloses a multifunctional and efficient SOFC power generation management method for islands, comprising:

[0084] S1: Heat diesel fuel to evaporate into diesel vapor and collect heating parameter information.

[0085] The heating parameter information refers to parameters such as temperature, fuel inlet status, and sulfur content when heating diesel fuel. This includes the heating temperature, unit fuel inlet rate, and steam sulfur content. The heating temperature is the temperature at which diesel fuel is heated, obtained by querying the heating device used to heat the diesel. The unit fuel inlet rate is the amount of diesel fuel introduced per unit time, obtained by querying the valve controlling the diesel fuel inlet to the heating device. The steam sulfur content is detected by a sulfur detection device pre-installed on the heating device.

[0086] The heating device can be an electrically heated vaporizer, a flame-heated vaporizer, a heat carrier-heated vaporizer, or the like. In this embodiment, the heating device is an electrically heated vaporization chamber.

[0087] The sulfur element detection device can be an ultraviolet fluorescence sensor. After the ultraviolet fluorescence sensor irradiates sulfur oxides to produce fluorescence, the sulfur content is detected based on the direct proportionality between the fluorescence intensity and the sulfur content.

[0088] By introducing diesel fuel into a heating device for heating diesel fuel, the diesel fuel is volatilized and generated into diesel vapor, which facilitates subsequent cracking and reforming of the diesel fuel.

[0089] S2: Generate inhalation control information based on the heating parameter information.

[0090] The intake control information refers to the rate and time at which the micro-interface reformer draws in diesel vapor. The micro-interface reformer is a device that disperses and breaks down diesel vapor and water vapor into micron-sized bubbles or droplets, then reforms and pyrolyzes them to generate hydrogen and carbon monoxide. The micro-interface reformer is preset by the operator.

[0091] By processing the heating parameter information, inhalation control information is generated for subsequent use. The specific method for generating the inhalation control information is described in S21 to S26.

[0092] S3: Based on the inhalation control information, the preset micro-interface reformer is controlled to inhale water vapor and diesel vapor and perform cracking and reforming to generate a mixed gas.

[0093] In this process, by inputting intake control information into a preset micro-interface reformer, the preset micro-interface reformer is controlled to intake water vapor and diesel vapor and perform cracking and reforming to generate a mixed gas containing hydrogen and carbon monoxide, which is convenient for subsequent power generation using hydrogen and carbon monoxide.

[0094] S4: Collect temperature readings and mixing information of the mixed gas.

[0095] The temperature detection value refers to the temperature value corresponding to the mixed gas containing hydrogen and carbon monoxide. The temperature detection value is obtained by a temperature sensor preset on the micro-interface reformer.

[0096] Mixture information refers to the content and ratio of hydrogen and carbon monoxide in a gas mixture. This information can be obtained through detection using equipment such as gas chromatographs or infrared gas analyzers.

[0097] S5: Generate heat delivery control information based on the temperature detection value and the mixing information.

[0098] Among them, the heat delivery control information refers to the control information used to control the delivery of the mixed gas to the SOFC stack. An SOFC stack is a device used to generate electricity from hydrogen and carbon monoxide gas. The SOFC stack is preset by the operator.

[0099] By analyzing the temperature detection values ​​and mixing information, heat delivery control information is generated for convenient subsequent use.

[0100] S6: Based on the heat delivery control information, the mixed gas is delivered to the preset SOFC stack for power generation.

[0101] The system controls the opening and closing of preset input pipelines and temperature conditions through heat delivery control information, thereby delivering mixed gas to preset SOFC stacks for power generation. This allows for precise control of the SOFC stacks to generate electricity, thereby reducing air pollution generated during island power generation.

[0102] The input pipeline is pre-installed on the SOFC stack and is used to input the mixed gas.

[0103] In step S2, in order to further ensure the rationality of the inhalation control information, it is necessary to perform further separate analysis and calculation on the inhalation control information, which will be explained in detail through the following steps.

[0104] The method for generating inhalation control information includes the following steps:

[0105] S21: Retrieve the heating temperature value and unit oil intake based on the heating parameter information.

[0106] The system retrieves heating temperature and unit oil intake information via heating parameters for convenient subsequent use.

[0107] S22: Determine the heating pressure value based on the heating temperature value and the unit oil intake quantity.

[0108] The heating pressure value refers to the pressure value of the diesel vapor formed after heating diesel fuel.

[0109] Since the heating pressure is positively correlated with the heating temperature, the higher the temperature, the stronger the tendency for the liquid to evaporate into gas, and the greater the saturated vapor pressure. Furthermore, when conditions such as pipe diameter and fuel viscosity remain constant, the heating pressure is also positively correlated with the unit fuel intake. Therefore, by inputting the heating temperature and unit fuel intake into a preset heating pressure database to obtain the matching heating pressure value, subsequent use is facilitated.

[0110] The heating pressure database has a pre-stored table of different heating temperature values ​​and unit oil intake quantities and corresponding heating pressure values. The heating pressure database is obtained and stored by the operator after conducting tests on different heating temperature values ​​and unit oil intake quantities.

[0111] S23: Generate an inhalation rate value and an inhalation time value based on the heating pressure value.

[0112] The intake rate value refers to the rate at which the micro-interface reformer draws in diesel vapor or water vapor, while the intake time value refers to the time at which the micro-interface reformer draws in diesel vapor or water vapor.

[0113] By analyzing the heating gas pressure value, the inhalation rate value and inhalation time value are generated for convenient subsequent use.

[0114] The specific methods for generating the inhalation rate and inhalation time values ​​are described in S231 to S235.

[0115] S24: Collect the current time point and the island's location.

[0116] The current time point refers to the time corresponding to the current time, which is obtained by querying the database that keeps track of time in real time.

[0117] The island location point refers to the location of the island where the SOFC fuel cell stack generates electricity. The island location point can be obtained by querying the position sensor preset at the location of the SOFC fuel cell stack, or it can be obtained by pre-entering the location point by the operator.

[0118] S25: Generate the intake molar ratio based on the unit oil intake, the current time point, and the island location point.

[0119] The intake molar ratio refers to the ratio between the number of moles of diesel vapor and the number of moles of water vapor inhaled by the intake micro-interface reformer.

[0120] By analyzing the unit oil intake, the current time point, and the island location, the intake molar ratio is generated for convenient subsequent use.

[0121] For the specific method of generating the inhalation molar ratio, refer to S251 to S256.

[0122] S26: Determine inhalation adjustment information based on the inhalation rate value, the inhalation time value, and the inhalation molar ratio, and use the inhalation adjustment information as the inhalation control information.

[0123] Among them, the intake adjustment information refers to the control information corresponding to the intake of diesel vapor or water vapor by the micro-interface reformer.

[0124] By combining the inhalation rate value, inhalation time value, and inhalation molar ratio, control information for the inhalation of diesel vapor or water vapor is formed and used as inhalation adjustment information. Then, the inhalation adjustment information is used as inhalation control information, thereby improving the accuracy of the acquired inhalation control information.

[0125] In step S21, in order to further ensure the rationality of the heating temperature value, it is necessary to perform a further separate analysis and calculation on the heating temperature value, which will be explained in detail through the following steps.

[0126] Following the step of retrieving the heating temperature value and unit oil intake based on the heating parameter information, the following steps are also included:

[0127] S211: Calculate the sulfur content of the steam based on the heating parameter information.

[0128] Among them, steam sulfur content refers to the sulfur content in diesel steam.

[0129] The sulfur content of the steam can be retrieved by adjusting the heating parameter information, which facilitates subsequent use.

[0130] S212: Determine the unit sulfur content based on the unit oil intake.

[0131] The sulfur content per unit refers to the maximum tolerable sulfur content during normal evaporation of diesel fuel at a given unit feed rate. Different feed rates correspond to different sulfur contents per unit.

[0132] The product between the unit oil intake and the preset sulfur content benchmark ratio is calculated, and the result is used as the unit sulfur content for convenient subsequent use.

[0133] The sulfur content benchmark ratio refers to the ratio between a unit amount of oil intake and a unit sulfur content. The sulfur content benchmark ratio is obtained after being pre-input by the operator.

[0134] S213: If the sulfur content of the steam is greater than the unit sulfur content, determine the sulfur content adjustment value.

[0135] The sulfur content adjustment value refers to the adjustment value used when adjusting the sulfur content in diesel vapor.

[0136] When the sulfur content in the steam exceeds the unit sulfur content, it indicates that the temperature is too high, causing the sulfur content in the diesel steam to exceed the standard. Therefore, the difference between the sulfur content in the steam and the unit sulfur content is calculated, and the calculation result is used as a sulfur content adjustment value for subsequent use.

[0137] S214: Determine the heating adjustment value based on the sulfur content adjustment value.

[0138] The heating adjustment value refers to the adjustment value required when the heating temperature needs to be adjusted. Different sulfur content adjustment values ​​correspond to different heating adjustment values.

[0139] By inputting the sulfur content adjustment value into a preset heating adjustment database, a matching heating adjustment value is obtained, which facilitates subsequent use.

[0140] The heating adjustment database has a pre-stored table of different sulfur content adjustment values ​​and their corresponding heating adjustment values. The heating adjustment database is obtained after the operator pre-inputs the values.

[0141] S215: Adjust and update the heating temperature value based on the heating adjustment value.

[0142] Specifically, by adjusting and updating the heating temperature value through heating adjustment, the accuracy of the obtained heating temperature value is improved, the sulfur content of diesel vapor obtained based on the heating temperature value is reduced, thereby reducing air pollution and improving subsequent power generation efficiency.

[0143] In step S23, in order to further ensure the rationality of the inhalation rate value and the inhalation time value, it is necessary to perform further separate analysis and calculation on the inhalation rate value and the inhalation time value, which will be explained in detail through the following steps.

[0144] The method for generating inhalation rate and inhalation time values ​​includes the following steps:

[0145] S231: Obtain the device specifications corresponding to the preset micro-interface remodeler.

[0146] The device specifications refer to the specific model and specifications of the micro-interface remodeler. These specifications can be obtained by querying the micro-interface remodeler.

[0147] S232: Retrieve the inhalation diameter and inhalation volume based on the device specifications.

[0148] Here, the suction diameter refers to the diameter of the pipe through which the micro-interface reformer draws in diesel vapor, and the suction volume refers to the volume of diesel vapor drawn in by the micro-interface reformer during reforming.

[0149] The device specifications are queried from a pre-set database to obtain the inhalation diameter and volume, facilitating subsequent use.

[0150] The specification database contains a pre-stored table of different equipment specifications and their corresponding inhalation diameters and volumes, which are obtained after pre-input.

[0151] S233: Determine the inhalation flow rate value based on the heating gas pressure value and the inhalation diameter.

[0152] The intake flow rate value refers to the flow rate corresponding to the intake of diesel vapor. Different heating gas pressures and intake diameters correspond to different intake flow rates.

[0153] The inhalation flow rate value is obtained by inputting the heating gas pressure value and the inhalation diameter into a preset inhalation flow rate database, which facilitates subsequent use.

[0154] The inhalation flow rate database contains a pre-stored table of different heating pressure values, inhalation diameters, and corresponding inhalation flow rate values. The inhalation flow rate database is obtained and stored by the operator after conducting experiments based on different heating pressure values ​​and inhalation diameters.

[0155] S234: Generate a flow rate adjustment value based on the inhalation flow rate value and the equipment specifications.

[0156] The flow rate adjustment value refers to the flow rate value after the flow rate has been adjusted.

[0157] By analyzing the inhalation flow rate and equipment specifications, flow rate adjustment values ​​are generated for convenient subsequent use.

[0158] The specific method for generating the flow rate adjustment value is described in S2341 to S2347.

[0159] S235: Determine the required time value based on the inhalation volume and the flow rate adjustment value, and use the required time value as the inhalation time value and the flow rate adjustment value as the inhalation rate value.

[0160] The demand time value refers to the time corresponding to the intake of diesel vapor. By calculating the quotient between the intake volume and the flow rate adjustment value, and using the calculation result as the demand time value, and then using the demand time value as the intake time value, and the flow rate adjustment value as the intake rate value, the accuracy of the obtained intake time value and intake rate value is improved.

[0161] In step S234, in order to further ensure the rationality of the flow rate adjustment value, it is necessary to perform a further separate analysis and calculation on the flow rate adjustment value, which will be explained in detail through the following steps.

[0162] The method for generating flow rate adjustment values ​​includes the following steps:

[0163] S2341: Retrieve the maximum flow rate value based on the device specifications.

[0164] The maximum flow rate refers to the maximum flow rate that the micro-interface reformer can achieve when drawing in diesel vapor through its pipes. Different equipment specifications correspond to different maximum flow rate values.

[0165] The maximum flow rate value is obtained by inputting the equipment specifications into a preset specification database, which facilitates subsequent use.

[0166] The specification database also pre-stores a table of different equipment specifications and their corresponding maximum flow rates, which is obtained after pre-input.

[0167] S2342: Determine whether the inhalation flow rate value is less than the maximum flow rate value. If yes, proceed to S2343; if no, proceed to S2344.

[0168] Specifically, by determining whether the inhalation flow rate is less than the maximum flow rate, it can be determined whether the inhalation flow rate needs to be adjusted.

[0169] S2343: The inhalation flow rate value is directly used as the flow rate adjustment value.

[0170] When the inhalation flow rate is less than the maximum flow rate, it means that there is no need to adjust the inhalation flow rate at this time, so the inhalation flow rate is directly used as the flow rate adjustment value.

[0171] S2344: Calculate the product between the inhalation flow rate value and the preset spiral unit adjustment value, and use it as the initial flow rate adjustment value.

[0172] The spiral unit adjustment value refers to the adjustment value corresponding to the flow rate adjustment when using a spiral tube of unit length. The spiral unit adjustment value is obtained after pre-input. The initial flow rate adjustment value refers to the adjustment value corresponding to the initial adjustment of the flow rate.

[0173] When the inhalation flow rate is not less than the maximum flow rate, it means that the inhalation flow rate needs to be adjusted. Therefore, the product between the inhalation flow rate and the preset spiral unit adjustment value is calculated and used as the initial flow rate adjustment value for convenient subsequent use.

[0174] S2345: Calculate the difference between the initial flow rate adjustment value and the maximum flow rate value and use it as the flow rate deviation value.

[0175] Among them, the flow velocity deviation value refers to the deviation value corresponding to the existence of a flow velocity deviation.

[0176] The difference between the initial flow rate adjustment value and the maximum flow rate value is calculated and used as the flow rate deviation value for convenient subsequent use.

[0177] S2346: Determine the adjustment value based on the flow rate deviation value.

[0178] Here, the adjustment value refers to the number of units of spiral tube required per unit length. Different flow rate deviations correspond to different adjustment values.

[0179] By inputting the flow velocity deviation value into a preset adjustment number database, the adjustment number corresponding to the matched flow velocity deviation range can be obtained, which is convenient for subsequent use.

[0180] The adjustment quantity database pre-stores different flow velocity deviation ranges and their corresponding adjustment values. The operator conducts experiments based on different adjustment values ​​to obtain and store the flow velocity deviation ranges.

[0181] S2347: Determine the final flow rate adjustment value based on the initial flow rate adjustment value, the preset spiral unit adjustment value, and the adjustment quantity value, and use the final flow rate adjustment value as the flow rate adjustment value.

[0182] The final adjustment value of the flow velocity refers to the final adjustment value after the flow velocity has been adjusted.

[0183] The accuracy of the obtained flow rate adjustment value is improved by inputting the adjustment value into a preset number adjustment database to match the number adjustment coefficient, calculating the product between the number adjustment coefficient and the spiral unit adjustment value, calculating the product between the adjustment value and the initial flow rate adjustment value, and using the final flow rate adjustment value as the flow rate adjustment value.

[0184] The number adjustment database pre-stores different adjustment values ​​and corresponding number adjustment coefficients, which are obtained after pre-input.

[0185] In step S25, in order to further ensure the rationality of the inhalation molar ratio, it is necessary to perform a further separate analysis and calculation of the inhalation molar ratio, which will be explained in detail through the following steps.

[0186] The method for generating the intake molar ratio includes the following steps:

[0187] S251: Determine the population density, industry type, and energy storage type based on the location of the island.

[0188] Population density refers to the number of people per unit area on the island, industry type refers to the type of industry on the island that requires electricity, and energy storage type refers to the type of equipment used to store electrical energy. Different locations on the island correspond to different population density values, industry types, and energy storage types.

[0189] By inputting the island location points into a preset island location database, population density, industry type, and energy storage type can be matched to facilitate subsequent use.

[0190] The island location database pre-stores a table showing the correspondence between different island locations and their corresponding population density, industry type, and energy storage type. The island location database is obtained after pre-input.

[0191] S252: Determine the industrial electricity consumption value based on the industry type and the current time point.

[0192] Among them, industrial electricity consumption value refers to the electricity consumption corresponding to the industry type at the current time. Different industry types correspond to different industrial electricity consumption values ​​at the current point in time.

[0193] By inputting the industry type and the current time point into a preset industry electricity consumption database, the industry electricity consumption value is obtained for convenient subsequent use.

[0194] The industrial electricity consumption database pre-stores a table mapping different industry types to their corresponding electricity consumption values ​​at the current time. The database is accessed by pre-storing the electricity consumption values ​​for different time points and industry types.

[0195] S253: Determine the population electricity consumption value based on the population density value.

[0196] Among them, the population electricity consumption value refers to the amount of electricity required by the population. Different population densities correspond to different population electricity consumption values.

[0197] The population electricity consumption value is obtained by multiplying the population density value with the preset electricity consumption value per unit of population, which is convenient for subsequent use.

[0198] The electricity consumption per unit of population is the electricity consumption per unit of population density. The electricity consumption per unit of population is obtained after pre-input.

[0272] Among them, the heating requirement refers to the amount of heat required to heat the pure water produced to the required heating value.

[0273] When the amount of hot water heated is greater than the amount of pure water produced, it indicates that the SOFC stack needs to dissipate heat. Therefore, by calculating the amount of pure water produced and the required heating value, the required heat can be obtained for subsequent use.

[0274] S66: Determine the remaining heat dissipation information of power generation based on the remaining heat generated and the heat demanded for heating, and output the remaining heat dissipation information of power generation to control the preset SOFC stack to dissipate heat.

Finally, the residual heat dissipation information is output to control the preset SOFC stack to dissipate heat, thereby ensuring that the SOFC stack can continue to generate electricity.

[0277] The database of residual heat dissipation from power generation is pre-stored with different heat differences and corresponding residual heat dissipation information from power generation. The database of residual heat dissipation from power generation is obtained after pre-input.

[0280] By separating the water corresponding to the hot water heating from the pure water production, water distribution control information is generated and output to control the preset SOFC stack to distribute water. This allows the hot water heating to dissipate heat from the SOFC stack while the remaining water is output as cold water, making it convenient for people on the island to use both cold and hot water at the same time.
