Description

Technology Field

[0001] The technical concept of the present disclosure relates to a control system and a control method for real-time linked operation of a fuel production process and a power generation process, and more specifically, to a fuel production process and power generation process control system and a control method thereof that automatically adjusts the process conditions of the power generation process according to fuel characteristic information and automatically adjusts the process conditions of the fuel production process according to output information of the power generation process. Background Technology

[0002] Solid biofuels, produced by compressing biomass into granular forms of a uniform size, are widely used as eco-friendly energy sources. Biomass refers to renewable biological resources and is recognized as an important energy source capable of replacing fossil fuels.

[0003] These biofuels can be used in a power generation process where they are burned through a boiler or combustor to generate thermal energy, and the generated thermal energy is converted into electrical energy through a turbine and a generator.

[0004] However, in power generation processes using biofuels, there is a problem in that combustion efficiency and power generation efficiency fluctuate significantly depending on variations in fuel quality. For example, if the moisture content of the fuel is high, a large amount of heat is consumed for the evaporation of water during combustion, which can lead to a decrease in combustion efficiency and a reduction in the output of the generator. Conversely, if the calorific value of the fuel is high, the combustion reaction proceeds excessively, causing the temperature of the combustion section to rise and potentially overloading the equipment.

[0005] Furthermore, if the variation in fuel particle size is large, the combustion speed becomes uneven, leading to reduced combustion stability and potentially causing fluctuations in the generator's output. Such output fluctuations not only reduce power generation efficiency but can also act as a factor that shortens the lifespan of the power generation equipment.

[0006] Nevertheless, conventional power generation processes faced a problem where fuel characteristic information, such as calorific value, moisture content, and particle size variation, was not sufficiently reflected in the process conditions. In other words, the fuel input and gas supply amounts to the combustion section were often set regardless of the fuel's condition or based on the operator's experience.

[0007] In addition, conventionally, the output status of the power generation process was not fed back to the fuel production process, so there was a problem in that it was difficult to properly adjust the fuel supply amount according to the load status of the power generation process. For example, even when the output of the generator was reduced, the fuel supply could not be sufficiently increased, or even when the output of the generator was excessively high, the fuel supply continued, which could cause equipment overload.

[0008] Therefore, there is a growing need for an integrated control system capable of precisely controlling process conditions of the power generation process based on fuel characteristic information and dynamically adjusting fuel supply by feeding back the output status of the power generation process to the fuel conversion process. The problem to be solved

[0036] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0037] FIG. 1 is a schematic system diagram of a fuel production process and power generation process system according to one embodiment.

[0038] According to one embodiment, the fuel production process may represent a process for producing fuel from forest biomass. According to one embodiment, the fuel production process may include a crushing process for crushing forest biomass, a drying process for drying the crushed forest biomass, a mixing process for mixing the dried forest biomass with a binder, and a molding process for molding the forest biomass mixed with the binder to produce fuel.

[0039] According to one embodiment, the power generation process may represent a process of producing electricity by burning fuel.

[0040] Conventionally, there was a problem in that specific information, such as the moisture content, calorific value, and particle size variation of the fuel produced by the fuel production process, was not sufficiently reflected in the process conditions of the power generation process. In addition, conventionally, since the fuel production process and the power generation process were operated independently of each other, the output status of the power generation process was not fed back to the fuel production process, making it difficult to appropriately adjust the fuel production conditions according to the output status of the power generation unit. For example, conventionally, even when the output of the power generation process was good, the fuel production speed of the fuel production process could not be sufficiently increased, resulting in a decrease in the overall production efficiency of the system. Conventionally, even in situations where the output of the power generation process was excessively high and could cause an overload on the equipment of the power generation process, fuel was continuously produced by the fuel production process, resulting in an oversupply of fuel. A control system (1) for real-time linked operation of the fuel production process and the power generation process according to one embodiment can perform the power generation process by reflecting the process conditions of the power generation process, which reflect the characteristic information of the fuel, in real time. A control system (1) for real-time linked operation of a fuel production process and a power generation process according to one embodiment can ensure stable operation of the fuel production process equipment by reflecting the output state of the power generation process in real time to the process conditions of the fuel production process, and can increase the production efficiency of the entire system.

[0041] That is, according to one embodiment, the fuel production process and the power generation process can be operated in real time by means of a control system (1) for real-time linked operation of the fuel production process and the power generation process. More specifically, characteristic information including the moisture content, calorific value, and particle size deviation of the fuel produced in the fuel production process can be reflected in the operating conditions of the power generation process, and the output state of the power generation process can be fed back to the production conditions of the fuel production process. Accordingly, combustion stability and output stability of the power generation process can be maintained even in a forest biomass environment with large fuel quality deviations, and stable continuous operation, fuel quality homogenization, and production efficiency improvement can be achieved at the actual production site.

[0042] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process may include a fuel production unit (10), a characteristic acquisition unit (20), a receiving unit (40), a power generation unit (50), and a control unit (30). According to one embodiment, fuel may be sequentially moved to the fuel production unit (10), the characteristic acquisition unit (20), the receiving unit (40), and the power generation unit (50). The fuel production unit (10), the characteristic acquisition unit (20), the receiving unit (40), and the power generation unit (50) are arranged in-line so that a fuel production process for manufacturing fuel can be performed continuously.

[0043] According to one embodiment, the control unit (30) can control the overall operation of the control system (1) for real-time linked operation of the fuel production process and the power generation process.

[0044] According to one embodiment, the fuel production unit (10) can produce fuel using forest biomass. More specifically, the fuel production unit (10) can produce forest biomass in the form of pellets. According to one embodiment, the pellets may represent solid fuel formed by compressing raw materials into granular shapes of a certain size.

[0045] According to one embodiment, the fuel production unit (10) may include an input unit (11), a crushing unit (12), a drying unit (13), a mixing unit (14), and a molding unit (15). According to one embodiment, forest biomass may be input into the input unit (11). According to one embodiment, the crushing unit (12) may crush the forest biomass. According to one embodiment, the drying unit (13) may dry the crushed forest biomass. According to one embodiment, the mixing unit (14) may mix the dried forest biomass with a binder. According to one embodiment, the molding unit (15) may compress the forest biomass mixed with the binder to obtain fuel in the form of pellets.

[0046] According to one embodiment, forest biomass may include unused wood, sawdust, wood chips, and agricultural by-products. Unused wood may include products from logging for forest tending, logging products from forest pest and disease control processes such as removing damaged trees, products from logging and pruning processes for the establishment and management of street trees, and products that are not used for raw timber production as forest fire-damaged trees.

[0047] According to one embodiment, the characteristic acquisition unit (20) may be configured to acquire characteristic information including the calorific value, moisture content, and particle size deviation of the fuel. According to one embodiment, the calorific value may be defined as an indicator representing the thermal energy generated per unit mass when the fuel is burned. According to one embodiment, the moisture content may be defined as an indicator representing the amount of moisture contained in the fuel, and may be defined as the mass ratio of moisture to the total mass of the fuel. According to one embodiment, the particle size deviation may be defined as an indicator representing the standard deviation of the size of the particles constituting the fuel.

[0048] According to one embodiment, the characteristic acquisition unit (20) may include a sensor for acquiring characteristic information of fuel. According to one embodiment, the characteristic acquisition unit (20) may include at least one of a moisture sensor, a near-infrared sensor, or an image sensor. According to one embodiment, the characteristic acquisition unit (20) may further include a module that stores a lookup table in which a sensing value acquired by the sensor and corresponding characteristic information are mapped.

[0049] According to one embodiment, the characteristic acquisition unit (20) can acquire the moisture content of forest biomass using a moisture sensor. According to one embodiment, the characteristic acquisition unit (20) can measure electrical characteristics (e.g., resistance, permittivity) in a contact or non-contact manner using a moisture sensor. According to one embodiment, the characteristic acquisition unit (20) can acquire the moisture content corresponding to the measured electrical characteristics by comparing the measured electrical characteristics with the previously stored electrical characteristics based on a lookup table.

[0050] According to one embodiment, the characteristic acquisition unit (20) may acquire the moisture content and heat output using a near-infrared sensor. According to one embodiment, the characteristic acquisition unit (20) may irradiate the fuel with near-infrared light using a near-infrared sensor and measure the reflected or absorbed spectrum. According to one embodiment, the characteristic acquisition unit (20) may acquire the moisture content and heat output by comparing the measured spectrum with a stored spectrum based on a lookup table.

[0051] According to one embodiment, the characteristic acquisition unit (20) can acquire particle size deviation using an image sensor. According to one embodiment, the characteristic acquisition unit (20) can acquire an image containing fuel using an image sensor. According to one embodiment, the characteristic acquisition unit (20) can acquire the size and particle size deviation of the fuel particles included in the image.

[0052] According to one embodiment, the power generation unit (50) may include a combustion unit (51) and a generator (52). The combustion unit (51) may burn fuel. The generator (52) may produce power from the heat generated in the combustion unit (51). For example, the generator (52) may include a turbine generator.

[0053] According to one embodiment, the control unit (30) may obtain power generation conditions corresponding to characteristic information and control the power generation unit (50) to perform a power generation process according to the power generation conditions. According to one embodiment, the power generation conditions may include a gas supply amount supplied to the combustion unit (51) and a fuel input amount introduced into the combustion unit. According to one embodiment, the gas supplied to the combustion unit (51) may include at least one of air, inert gas, or oxygen, and the type of gas may not be limited thereto. According to one embodiment, the gas supplied to the combustion unit (51) may include exhaust gas discharged from a previously performed power generation process.

[0054] According to one embodiment, the control unit (30) can obtain a combustion stability index using characteristic information and mathematical formula 1.

[0055]

[0056] w1 represents the calorific value weight, w2 represents the moisture content weight, and w3 represents the particle size deviation weight.

[0057] According to one embodiment, weights (w1, w2, w3) may be set based on simulation results. For example, the weights may be determined by measuring the combustion efficiency and power generation efficiency of the power generation unit (50) under various calorific value, moisture content, and particle size deviation conditions, and analyzing the influence of characteristic information on combustion stability based on the measurement results. Combustion efficiency may represent the ratio of the calorific value during complete combustion to the calorific value during actual combustion, and power generation efficiency may represent the ratio of supplied thermal energy to generated electrical energy.

[0058] According to one embodiment, weights may be calculated using regression analysis, a machine learning model, or an optimization algorithm, and may be updated using data accumulated during the power generation process and fuel conversion process.

[0059] According to one embodiment, w1 may be greater than w2 and w3, and w2 may be greater than w3. According to one embodiment, since the calorific value is the factor that has the greatest influence on combustion stability, w1 may be set to be greater than w2 and w3; since the moisture content affects combustion efficiency and ignitability, w2 may be set to an intermediate level; and since the particle size variation affects combustion uniformity, w3 may be set to a relatively small value.

[0060] According to one embodiment, w1 may be 0.5 to 0.7, 0.55 to 0.7, 0.6 to 0.7, or 0.65 to 0.7. According to one embodiment, w2 may be 0.2 to 0.4, 0.25 to 0.4, 0.3 to 0.4, or 0.35 to 0.4. According to one embodiment, w3 may be 0.05 to 0.2, 0.1 to 0.2, or 0.15 to 0.2. For example, if w1 is less than 0.5, the influence of calorific value is underreflected, so the combustion stability index may not sufficiently reflect actual combustion performance; conversely, if w1 exceeds 0.7, the influence of moisture content and particle size deviation is relatively underreflected, so the accuracy of the combustion stability judgment may be reduced. Furthermore, if w2 is less than 0.2, the decrease in combustion efficiency due to increased moisture content may not be sufficiently reflected, and if w2 exceeds 0.4, the influence of moisture content relative to calorific value may be excessively reflected, potentially distorting the combustion stability index. Additionally, if w3 is less than 0.05, combustion non-uniformity due to particle size variation may not be sufficiently reflected, and if w3 exceeds 0.2, the influence of particle size variation may be excessively reflected, potentially lowering the reliability of the overall combustion stability index. Therefore, by setting the above weights within the above range, a combustion stability index that reflects fuel characteristic information in a balanced manner can be obtained, thereby improving combustion stability and power generation efficiency. More specifically, w1 can be set to 0.6, w2 to 0.3, and w3 to 0.1. In this case, the influence of calorific value is reflected most significantly, followed by the influence of moisture content, and the influence of particle size variation is reflected relatively less, allowing for a high improvement in combustion stability and power generation efficiency. However, the numerical ranges of w1, w2, and w3 may not be limited to this.

[0061] According to one embodiment, the control unit (30) can obtain the amount of fuel input and the amount of gas supplied to the combustion unit (51) based on the combustion stability index. According to one embodiment, the greater the combustion stability index, the greater the amount of fuel input and the smaller the amount of gas supplied to the combustion unit (51). According to one embodiment, the control unit (30) can obtain the amount of fuel input and the amount of gas supplied using a lookup table that maps the combustion stability index to the amount of fuel input and the amount of gas supplied. That is, as the combustion stability index increases, the combustion efficiency improves, so the amount of gas supplied to the combustion unit can be reduced so that it is not oversupplied.

[0062] According to one embodiment, the receiving section (40) may receive fuel supplied from the fueling section (10). According to one embodiment, the receiving section (40) may be a silo. According to one embodiment, the receiving section (40) may include a chamber (41 in FIG. 3), a first inlet member (41a in FIG. 3), a second inlet member (42a in FIG. 3), a first outlet member (41b in FIG. 3), a second outlet member (42b in FIG. 3), and a mixing member (not shown). According to one embodiment, the chamber (41) may include a first receiving space (41c) for receiving fuel with a moisture content lower than a reference moisture content and a second receiving space (42c) for receiving fuel with a moisture content greater than or equal to a reference moisture content. According to one embodiment, the first inlet member (41a) may be an inlet passage through which fuel is introduced into the first receiving space (41c), and the second inlet member (42a) may be an inlet passage through which fuel is introduced into the second receiving space (42c). The first discharge member (41b) may be positioned at a location corresponding to the first receiving space (41c) to discharge the fuel contained in the first receiving space (41c) to the outside, and the second discharge member (42b) may be positioned at a location corresponding to the second receiving space (42c) to discharge the fuel contained in the second receiving space (42c) to the outside.

[0063] According to one embodiment, the control unit (30) can obtain a mixing ratio of fuel contained in the first receiving space (41c) and fuel contained in the second receiving space (42c) by comparing the target calorific value of the fuel with the calorific value of the fuel. According to one embodiment, if the target calorific value is less than the calorific value of the fuel, the control unit (30) can obtain a mixing ratio such that the amount of fuel contained in the second receiving space (42c) is greater than the amount of fuel contained in the first receiving space (41c). According to one embodiment, if the target calorific value is greater than or equal to the calorific value of the fuel, the control unit (30) can obtain a mixing ratio such that the amount of fuel contained in the first receiving space (41c) is greater than the amount of fuel contained in the second receiving space (42c).

[0064] According to one embodiment, the control unit (30) may obtain a mixing ratio of fuel contained in the first receiving space (41c) and fuel contained in the second receiving space (42c) by comparing the target moisture content of the fuel with the moisture content of the fuel. According to one embodiment, if the target moisture content is less than the moisture content of the fuel, the control unit (30) may obtain a mixing ratio such that the amount of fuel contained in the first receiving space (41c) is greater than the amount of fuel contained in the second receiving space (42c). According to one embodiment, if the target moisture content is greater than or equal to the moisture content of the fuel, the control unit (30) may obtain a mixing ratio such that the amount of fuel contained in the second receiving space (42c) is greater than the amount of fuel contained in the first receiving space (41c).

[0065] According to one embodiment, the control unit (30) obtains the opening rate of each of the first discharge member (41b) and the second discharge member (42b) corresponding to the mixing ratio, and can control the first discharge member (41b) and the second discharge member (42b) to be opened by their respective opening rates. For example, if the target calorific value is greater than or equal to the calorific value of the fuel, the control unit (30) can adjust the opening rate of the first discharge member (41b) to be greater than the opening rate of the second discharge member (42b). Accordingly, the calorific value of the fuel supplied to the power generation unit (50) can be adjusted by controlling the ratio of fuel discharged from the first receiving space (41c) and the second receiving space (42c). This is because the lower the moisture content of the fuel, the lower the heat energy that can be effectively used for combustion, i.e., the lower calorific value, is relatively larger because the lower the moisture content of the fuel, the lower the moisture content relative to the same mass. Therefore, increasing the supply ratio of fuel with low moisture content can increase the calorific value of the fuel supplied to the power generation unit. For example, if the target moisture content is less than the moisture content of the fuel, the control unit (30) can adjust the opening rate of the first exhaust member (41b) to be greater than the opening rate of the second exhaust member (42b).

[0066] According to one embodiment, the control unit (30) can control the power generation unit (50) to perform a power generation process with the acquired power generation conditions. According to one embodiment, the power generation unit (50) can perform a power generation process using the fuel mixing ratio, fuel input amount, and gas supply amount supplied to the combustion unit (51) that are fed into the combustion unit (51).

[0067] According to one embodiment, the control unit (30) can adjust the production speed of the fuel unit (10) based on the output information of the power generation unit (50). According to one embodiment, the output information of the power generation unit (50) may include power generated by the generator (52), the number of rotations of the generator (52), and the power generation efficiency of the generator (52). According to one embodiment, the control unit (30) can obtain an output index based on the output information and Equation 2.

[0068]

[0086] FIG. 3 schematically illustrates the connection relationship between the fuel unit, the receiving unit, and the power generation unit according to one embodiment.

[0087] Referring to FIG. 3, according to one embodiment, the receiving section (40) may be connected to the fueling section (10). According to one embodiment, the receiving section (40) may be connected to the power generation section (50).

[0088] According to one embodiment, the receiving portion (40) may include a chamber (41), a first inlet member (41a), a second inlet member (42a), a first discharge member (41b), and a second discharge member (42b). According to one embodiment, the chamber (41) may include a first receiving space (41c) for receiving fuel with a moisture content lower than a reference moisture content and a second receiving space (42c) for receiving fuel with a moisture content greater than or equal to a reference moisture content. The first receiving space (41c) and the second receiving space (42c) may be partitioned by a partition member (48). According to one embodiment, the distance between the lower surface of the chamber (41) and the first discharge member (41b) may be smaller than the distance between the lower surface of the chamber (41) and the second discharge member (42b). That is, the first receiving space (41c) may be provided on the lower side of the chamber (41) than the second receiving space (42c).

[0089] A control system (1) for real-time linked operation of a fuel production process and a power generation process may further include a branching section (70) that separates fuel with a moisture content lower than a reference moisture content and fuel with a moisture content higher than a reference moisture content to selectively branch the fuel transfer path. Fuel separated according to moisture content by the branching section (70) may be introduced into a first receiving space (41c) through a first inlet member (41a) or into a second receiving space (42c) through a second inlet member (42a). For example, the branching section (70) may be provided in a valve type, a gate type, or a conveyor type. For example, the valve type may include a damper, a slide valve, or a rotary valve. For example, the gate type may include a slide gate or a flap gate.

[0090] According to one embodiment, the first inlet member (41a) may be an inlet passage through which fuel is introduced into the first receiving space (41c), and the second inlet member (42a) may be an inlet passage through which fuel is introduced into the second receiving space (42c). The first discharge member (41b) may be positioned at a location corresponding to the first receiving space (41c) to discharge the fuel contained in the first receiving space (41c) to the outside, and the second discharge member (42b) may be positioned at a location corresponding to the second receiving space (42c) to discharge the fuel contained in the second receiving space (42c) to the outside.

[0091] According to one embodiment, fuel with a moisture content lower than a reference moisture content can be introduced into a first receiving space (41c) through a first inlet member (41a). According to one embodiment, fuel with a moisture content greater than or equal to a reference moisture content can be introduced into a second receiving space (42c) through a second inlet member (42a).

[0092] According to one embodiment, the control unit (30) can obtain a mixing ratio of fuel contained in the first receiving space (41c) and fuel contained in the second receiving space (42c) by comparing the target calorific value of the fuel with the calorific value of the fuel. According to one embodiment, the control unit (30) can obtain a mixing ratio by using a lookup table in which the mixing ratio corresponds to the relationship and difference between the target calorific value and the calorific value of the fuel. According to one embodiment, if the target calorific value is less than the calorific value of the fuel, the control unit (30) can obtain a mixing ratio such that the amount of fuel contained in the second receiving space (42c) is greater than the amount of fuel contained in the first receiving space (41c). According to one embodiment, if the target calorific value is greater than or equal to the calorific value of the fuel, the control unit (30) can obtain a mixing ratio such that the amount of fuel contained in the first receiving space (41c) is greater than the amount of fuel contained in the second receiving space (42c).

[0093] According to one embodiment, the control unit (30) can obtain a mixing ratio of fuel contained in the first receiving space (41c) and fuel contained in the second receiving space (42c) by comparing the target moisture content of the fuel with the moisture content of the fuel. According to one embodiment, the control unit (30) can obtain a mixing ratio by using a lookup table in which the mixing ratio corresponds to the relationship and difference between the target moisture content and the moisture content of the fuel. According to one embodiment, if the target moisture content is less than the moisture content of the fuel, the control unit (30) can obtain a mixing ratio such that the amount of fuel contained in the first receiving space (41c) is greater than the amount of fuel contained in the second receiving space (42c). According to one embodiment, if the target moisture content is greater than or equal to the moisture content of the fuel, the control unit (30) can obtain a mixing ratio such that the amount of fuel contained in the second receiving space (42c) is greater than the amount of fuel contained in the first receiving space (41c).

[0094] According to one embodiment, the control unit (30) can obtain the opening rate of each of the first discharge member (41b) and the second discharge member (42b) based on the obtained mixing ratio. For example, if the target calorific value is greater than or equal to the calorific value of the fuel, the control unit (30) can adjust the opening rate of the first discharge member (41b) to be greater than the opening rate of the second discharge member (42b). Accordingly, the calorific value of the fuel supplied to the power generation unit (50) can be adjusted by controlling the ratio of fuel discharged from the first receiving space (41c) and the second receiving space (42c). This is because the lower the moisture content of the fuel, the lower the heat energy that can be effectively used for combustion, i.e., the lower calorific value, is relatively larger because the moisture content is lower on the same mass basis. Therefore, increasing the supply ratio of fuel with low moisture content can increase the calorific value of the fuel supplied to the power generation unit. For example, if the target moisture content is greater than the moisture content of the fuel, the control unit (30) can adjust the opening rate of the second discharge member (42b) to be greater than the opening rate of the first discharge member (41b).

[0095] The opening rate of the first discharge member (41b) and the opening rate of the second discharge member (42b) corresponding to the mixing ratio can be stored in a lookup table. According to one embodiment, the control unit (30) can obtain the opening rate of the first discharge member (41b) and the opening rate of the second discharge member (42b) corresponding to the difference between the target calorific value of the fuel and the calorific value of the fuel by using the lookup table.

[0096] According to one embodiment, the receiving portion (40) may further include a mixing member. The mixing member may be rotatably provided within the chamber (41) and may be provided through the partition member (48). The mixing member may homogenize fuel contained in the first receiving space (41c) by stirring, and may homogenize fuel contained in the second receiving space (42c) by stirring.

[0100] Referring to FIG. 4, according to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can perform a fuel production process under a first production condition through a fuel production unit (10) in operation S410.

According to one embodiment, the characteristic information may include the calorific value of the fuel, moisture content, and particle size deviation.

[0102] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can obtain power generation conditions corresponding to characteristic information in operation S430.

[0103] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can perform a power generation process according to power generation conditions through a power generation unit (50) in operation S440. According to one embodiment, the power generation conditions may include at least one of a fuel input amount supplied to a combustion unit (51), a gas supply amount supplied to a combustion unit (51), or an opening rate of a first discharge member (41b) and a second discharge member (42b).

[0104] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can obtain output information of a power generation unit (50) in operation S450. According to one embodiment, the output information of the power generation unit (50) may include power generated by a generator (52), the number of rotations of the generator (52), and the power generation efficiency of the generator (52).

[0105] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can obtain a second production condition corresponding to output information in operation S460. The second production condition may include at least one of an input speed of an input section (11), a crushing speed of a crushing section (12), a drying temperature of a drying section (13), a flow rate of gas for drying in the drying section (13), an amount of binder of a mixing section (14), a molding temperature of a molding section (15), or a molding pressure of a molding section (15). According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can adjust at least one of the input speed of the input section (11), the grinding speed of the grinding section (12), the drying temperature of the drying section (13), the flow rate of gas for drying in the drying section (13), the amount of binder of the mixing section (14), the molding temperature of the molding section (15), or the molding pressure of the molding section (15) included in the second production condition according to output information, differently from the size of at least one of the input speed of the input section (11), the grinding speed of the grinding section (12), the drying temperature of the drying section (13), the flow rate of gas for drying in the drying section (13), the amount of binder of the mixing section (14), the molding temperature of the molding section (15), or the molding pressure of the molding section (15) included in the first production condition.

[0106] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can perform a fuel production process under a second production condition through a fuel production unit (10) in operation S470.

[0108] FIG. 5 is a flowchart illustrating a method for obtaining power generation conditions of a power generation unit using a combustion stability index based on characteristic information according to one embodiment.

[0109] Referring to FIG. 5, according to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can obtain a combustion stability index in operation S510.

[0110] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can obtain a combustion stability index according to Equation 3. According to one embodiment, the fuel production process and power generation process system (1) can calculate a combustion stability index based on the moisture content, calorific value, and particle size deviation of the fuel measured in real time in the fuel production process. Accordingly, the characteristic information of the fuel can be reflected in real-time in the power generation conditions of the power generation process.

[0111]

[0112] w1 represents the calorific value weight, w2 represents the moisture content weight, and w3 represents the particle size deviation weight.

[0113] According to one embodiment, weights (w1, w2, w3) may be set based on simulation results. For example, the weights may be determined by measuring combustion efficiency and power generation efficiency under various calorific values, moisture content, and particle size deviation conditions, and analyzing the influence of characteristic information on combustion stability based on the measurement results. Combustion efficiency may represent the ratio of the calorific value during complete combustion to the calorific value during actual combustion, and power generation efficiency may represent the ratio of supplied thermal energy to generated electrical energy.

[0114] According to one embodiment, weights may be calculated using regression analysis, a machine learning model, or an optimization algorithm, and may be updated using data accumulated during the power generation process and fuel conversion process.

[0115] According to one embodiment, w1 may be greater than w2 and w3, and w2 may be greater than w3. According to one embodiment, since the calorific value is the factor that has the greatest influence on combustion stability, w1 may be set to be greater than w2 and w3; since the moisture content affects combustion efficiency and ignitability, w2 may be set to an intermediate level; and since the particle size variation affects combustion uniformity, w3 may be set to a relatively small value.

[0116] According to one embodiment, w1 may be 0.5 to 0.7, 0.55 to 0.7, 0.6 to 0.7, or 0.65 to 0.7. According to one embodiment, w2 may be 0.2 to 0.4, 0.25 to 0.4, 0.3 to 0.4, or 0.35 to 0.4. According to one embodiment, w3 may be 0.05 to 0.2, 0.1 to 0.2, or 0.15 to 0.2. For example, if w1 is less than 0.5, the influence of calorific value is underreflected, so the combustion stability index may not sufficiently reflect actual combustion performance; conversely, if w1 exceeds 0.7, the influence of moisture content and particle size deviation is relatively underreflected, so the accuracy of the combustion stability judgment may be reduced. In addition, if w2 is less than 0.2, the decrease in combustion efficiency due to increased moisture content may not be sufficiently reflected, and if w2 exceeds 0.4, the influence of moisture content relative to calorific value may be excessively reflected, potentially distorting the combustion stability index. Furthermore, if w3 is less than 0.05, combustion non-uniformity due to particle size variation may not be sufficiently reflected, and if w3 exceeds 0.2, the influence of particle size variation may be excessively reflected, potentially lowering the reliability of the overall combustion stability index. More specifically, w1 can be set to 0.6, w2 to 0.3, and w3 to 0.1. In this case, the influence of calorific value is reflected most significantly, followed by the influence of moisture content, while the influence of particle size variation may be reflected relatively less.

[0117] According to one embodiment, a control system (1) for real-time linked operation of a fueling process and a power generation process can obtain power generation conditions corresponding to a combustion stability index in operation S530. The power generation conditions may include a combustion stability index, a fuel input amount, and a gas supply amount. According to one embodiment, a control system (1) for real-time linked operation of a fueling process and a power generation process can obtain a fuel input amount and a gas supply amount by using a lookup table that maps the combustion stability index, the fuel input amount, and the gas supply amount. Accordingly, the combustion stability and output stability of the power generation process can be maintained even in a forest biomass environment where fuel quality fluctuations are large, and stable continuous operation can be made possible at an actual production site.

[0118] According to one embodiment, a control system (1) for real-time linked operation of a fuel production process and a power generation process can perform a power generation process according to power generation conditions through a power generation unit (50) in operation S550.

[0119] Accordingly, the control system (1) for real-time linked operation of the fuel production process and the power generation process can reflect the characteristics of the fuel produced in the fuel production process in real-time linked to the power generation conditions of the power generation process, and can enable integrated linked operation between the fuel production process and the power generation process.

For example, if the production ratio of fuel with a high calorific value increases, the discharge ratio of fuel with a low calorific value increases, thereby maintaining the average calorific value of the fuel supplied to the power generation unit (50) within the target calorific value range.

[0124] According to one embodiment, a control system (1) for real-time linked operation of a fueling process and a power generation process can control the opening rate of each of the first discharge member (41b) and the second discharge member (42b) in operation S650.

[0125] According to one embodiment, by adjusting the opening rate of the first discharge member (41b) and the second discharge member (42b), fuels with different calorific values ​​can be mixed in real time. Accordingly, the quality of the fuel supplied to the power generation unit (50) can be maintained homogeneously, and fluctuations in power output and combustion unevenness due to fuel quality deviations can be reduced. In addition, stable continuous operation and improved power generation efficiency can be achieved in the actual forest biomass production process.

That is, a control system (1) for real-time linked operation of a fueling process and a power generation process can adjust the discharge ratio of the fuel contained in the first receiving space (41c) and the fuel contained in the second receiving space (42c) in real time so that the moisture content of the fuel corresponds to the target moisture content. For example, when the proportion of fuel with a high moisture content increases, the proportion of fuel with a low moisture content is increased, thereby maintaining the average moisture content of the fuel supplied to the power generation unit (50) within the target moisture content range.

[0132] According to one embodiment, a control system (1) for real-time linked operation of a fueling process and a power generation process can control the opening rate of each of the first discharge member (41b) and the second discharge member (42b) in operation S750.
