[0070] Example 1
[0071] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a process regulation control method based on production line joint production, including:
[0072] S1: According to the joint production of the production line, the full load state operation is completed under load regulation, and the change of power generation load is indirectly adjusted by adjusting the load of the ethanol production process.
[0073] The full load state includes adjusting the load of the power generation device by reducing or increasing the load of the ethanol process when the production line is co-producing ethanol;
[0074] Adjusting the load of the power generation device includes adjusting it according to the synthetic gas distribution rule of the power generation device. The synthetic gas distribution rule includes establishing a mathematical model of the system according to the operating characteristics of the ethanol production line under full load. The mathematical model includes processing the load range, load change rate, inertia characteristics and production efficiency of the production line co-generation device and the power generation device, and pre-analyzing the mathematical model through a multi-objective optimization algorithm;
[0075] The multi-objective optimization algorithm includes optimizing the parameters of the synthesis gas allocation rule according to multiple objectives, and calculating based on the optimized parameters to obtain the synthesis gas allocation rule. The specific calculation formula of the parameters is:

[0077] ,
[0078] in, Indicates the parameters, represents the total synthesis gas volume, represents the amount of synthesis gas for the power generation unit, It indicates the amount of synthesis gas in the co-generation unit of the ethanol production line.
[0079] Furthermore, in order to realize the full load and efficient operation of the production line cogeneration system under load regulation, the load of the ethanol production process is adjusted to indirectly adjust the change of the power generation load. Specifically, when the load of the ethanol production line changes, the system will dynamically adjust the amount of synthesis gas of the power generation device based on the current operating status and load characteristics of the ethanol production line to ensure that the entire system can operate stably and efficiently under different load conditions. To achieve this goal, the system has established a mathematical model that comprehensively considers factors such as load range, change rate, inertia characteristics, and production efficiency, and optimizes the parameters in the model through a multi-objective optimization algorithm. The system can reasonably allocate the amount of synthesis gas under complex conditions of multiple variables and multiple objectives, and realize precise regulation of the power generation device and the ethanol production line, thereby ensuring the optimal operation of the production line cogeneration system under different load conditions. This method not only improves the response speed and regulation accuracy of the system, but also significantly enhances the automatic regulation capability of the entire production line cogeneration system. The load data of the production line cogeneration system under load regulation are shown in Table 1 below:
[0080] Table 1 Load data of production line co-generation system under load regulation
[0081] ,
[0082] The load data of each device in the production line co-production system under different load adjustment conditions show that as the load of the power generation device gradually increases from 50% to 100%, the load of the ethanol device shows a gradual downward trend, from 100% to 40%, and drops to 0% when the load of the power generation device reaches 85% and above. At the same time, the load of the air separation and gasification devices is maintained at 100% when the load of the power generation device is 50% to 75%, fluctuates slightly after the load of the power generation device reaches 85%, and finally returns to 100% when the load of the power generation device reaches 100%. This table reflects the load distribution and adjustment relationship between each device in the process of load adjustment of the production line co-production system.
[0083] S2: In order to adjust the changes in power generation load, based on the impact of the rate of co-production of the production line, the fuel provided by the ethanol storage tank is used to optimize the load rate provided by the gas turbine during the co-production of the production line.
[0084] Among them, adjusting the change of power generation load includes decomposing the production line co-production under the full load state of load regulation, and the decomposition includes carrying out full load production of the production line co-production units according to air separation, gasification, purification and desulfurization, and adjusting the amplitude of the power generation device and the ethanol production line co-production device by calculating the parameters of the synthetic gas volume distribution rule;
[0085] When the system requires to increase the load of the power generation unit, the system will detect the current load status of the ethanol production line co-generation unit and reduce the amount of synthesis gas in the ethanol production line co-generation unit through the intelligent control system. , increase the total synthesis gas volume , so that the power generation load increases;
[0086] When the system requires to reduce the load of the power generation unit, the system will detect the current load status of the ethanol production line co-generation unit and increase the synthesis gas volume of the ethanol production line co-generation unit through the intelligent control system. , reducing the total syngas volume , so that the power generation load is reduced.
[0087] Furthermore, in the process of adjusting the changes in power generation load, the production line co-production system will optimize the load rate of the gas turbine according to the rate of the production line through the fuel provided by the ethanol storage tank. When the system detects that the load of the power generation unit needs to be increased, the system first analyzes the current load status of the ethanol production line. When the load of the power generation unit needs to be increased from 75% to 85%, the system will use the intelligent control system to gradually reduce the synthesis gas volume of the ethanol production line from 50% to 0%, and at the same time increase the total synthesis gas volume, so that the load of the power generation unit can be smoothly increased to 85%.
[0088] In the opposite case, if the load of the power generation unit needs to be reduced from 85% to 70%, the system will detect the current load status of the ethanol production line. At this time, the system will gradually increase the synthesis gas volume of the ethanol production line from 0% to 60%, so that the total synthesis gas volume is reduced, thereby reducing the load of the power generation unit to 70%. Through this series of operations, the production line co-production system can ensure reasonable load distribution of each unit under different load adjustment conditions, thereby optimizing overall production efficiency.
[0089] S2.1: Optimizing the load rate provided by the gas turbine during the production line co-production process includes using an intelligent control system to monitor the current load status of the power generation device and the ethanol production line co-production device. The specific calculation formula for monitoring is:
[0090] ,
[0091] in, It indicates the load rate of the gas turbine after the change in the production line co-production process. Indicates the current load of the power generation device, It indicates the current load of the ethanol production line co-generation unit;
[0092] When the load rate of the gas turbine changes during the production line co-production process When the preset threshold range of the production line joint production is exceeded, the system triggers the load rate adjustment mechanism;
[0093] The preset thresholds include setting safety parameters for the current loads of the power generation unit and the ethanol production line cogeneration unit based on the safe operation of the system, analyzing the operating status under different load conditions according to the simulation process of the mathematical model, and the simulation process of the mathematical model includes taking into account the load range, load change rate, inertia characteristics and production efficiency of the production line cogeneration unit and the power generation unit in the form of a multivariable linear or nonlinear equation system;
[0094] The calculation formula of the simulation process of the mathematical model is:
[0095] ,
[0096] in, Indicates the preset threshold value, It indicates the maximum load value that the mathematical model simulation system can bear. It indicates the minimum load value that the mathematical model simulation system can bear. It represents the rate of load change in the system simulated by the mathematical model. It indicates the response speed of load changes in the mathematical model simulation system. Represents a multivariate function;
[0097] The preset threshold is optimized by using a multi-objective optimization algorithm, and the optimized preset threshold is calculated. The specific calculation formula is:
[0098] ,
[0099] in, represents the optimized preset threshold, Represents the functional form of multi-objective optimization, represents the weight coefficient, Indicates the number of items, Indicates from 1 to Sum the number of items;
[0100] At this time, when When , the system triggers the load rate adjustment mechanism.
[0101] Furthermore, when optimizing the load rate of the gas turbine during the co-production process of the production line, the system monitors the current load status of the power generation unit and the ethanol production line through the intelligent control system. For example, if the current load of the power generation unit is 70% and the load of the ethanol production line is 60%, the system will calculate the load rate of the gas turbine. If the calculation result shows that the load rate of the gas turbine exceeds the system's preset threshold of 75%, the system will trigger the adjustment mechanism to ensure the safe and efficient operation of the entire production line co-production system.
[0102] S3: Based on the load regulation state of the production line joint production, the optimized load rate is adjusted, and the process regulation and control of the production line joint production is completed through the mutual feedback mechanism of the sensor and the data acquisition model.
[0103] The optimized load rate is adjusted by calculating the distribution ratio of the syngas between the power generation device and the ethanol production line co-generation device according to the syngas distribution rule, and adjusting the load rate of the gas engine based on the syngas distribution ratio and the fuel provided by the ethanol storage tank;
[0104] The calculation formula for the distribution ratio of synthesis gas is:
[0105] ,
[0106] in, Indicates the distribution ratio of synthesis gas, Indicates the maximum syngas demand of the power generation unit;
[0107] when When the load rate increases, the current load state of the ethanol production line co-production device is detected. ;
[0108] like When the syngas volume of the ethanol production line co-generation unit is reduced, the syngas volume of the power generation unit is increased, so that the load of the ethanol production process is in a normal state. Indicates the minimum value of the current load of the ethanol production line co-production device. At this time, the load rate of the gas turbine is adjusted. The specific calculation formula for the adjustment is:
[0109] ,
[0110] in, Indicates the load rate of adjusting the gas turbine. represents the base load rate, Indicates the fuel regulation factor for the load rate, Indicates the amount of fuel provided by the ethanol tank;
[0111] when When the load rate decreases, the current load of the ethanol production line co-production unit is detected. ;
[0112] like When the syngas volume of the ethanol production line co-production unit is increased, the syngas volume of the power generation unit is reduced, so that the load of the ethanol production process is in a normal state. At this time, the secondary load rate of the gas turbine is adjusted. The specific calculation formula for the adjustment is:
[0113] ,
[0114] in, Indicates the secondary load rate of adjusting the gas turbine. Indicates the fuel adjustment factor for the secondary load rate.
[0115] Furthermore, during the load regulation process of the production line, the system accurately adjusts the load rate of the gas turbine through the feedback mechanism of the sensor and data acquisition model. When the load of the power generation unit needs to increase from 75% to 85%, the system will reduce the syngas supply of the ethanol production line from 60% to 50%, and at the same time increase the syngas volume of the power generation unit to support higher power output. At the same time, the regulation amount of fuel oil is increased by 10% to ensure that the load rate of the gas turbine is increased to the required level. If the load of the power generation unit needs to be reduced to 70%, the syngas supply of the ethanol production line will be increased to 60% to maintain its production stability, and the load rate of the gas turbine will be reduced accordingly. By reasonably adjusting the amount of syngas and fuel oil, the system can ensure the stability and efficiency of the production line under different load conditions.
[0116] S3.1: The mutual feedback mechanism includes the system deploying sensors in the production line co-production process and sending the data collected by the sensors to the data acquisition model;
[0117] If the system detects that the data collected by the sensor exceeds the set range of a certain parameter in the co-production process of the production line, the data acquisition model transmits the feedback information to the control system, and the control system automatically adjusts the distribution ratio of the synthesis gas amount according to the feedback information to obtain the secondary distribution ratio;
[0118] The result of the secondary allocation ratio is transmitted to the data acquisition model for analysis through the sensor to verify whether the result of the secondary allocation ratio achieves the expected effect of the synthesis gas volume allocation rule;
[0119] If the expected effect is not achieved, the mutual feedback mechanism will be triggered N times. If the expected effect is achieved, the system will adjust the load rate of the gas turbine for a second time according to the secondary distribution ratio result that achieves the expected effect.
[0120] Furthermore, during the co-production process of the production line, the system uses sensors to monitor key parameters in real time. Assuming that the sensor detects that the distribution ratio of the synthesis gas volume deviates from the set range, the data acquisition model transmits this data to the control system. The control system then adjusts the distribution ratio of the synthesis gas volume based on the feedback information, from the initial 70% to 80%. The adjusted secondary distribution ratio result is sent back to the data acquisition model through the sensor for verification. If the secondary distribution ratio fails to achieve the expected effect, the mechanism will iterate multiple times (N times) for adjustment until it meets expectations. After three adjustments, the system reaches the expected ratio of 80%, and the control system adjusts the load rate of the gas turbine accordingly to maintain stable production.
[0121] S3.2: Secondary adjustment of the load rate of the gas turbine includes adjusting the load rate of the gas turbine again according to the secondary allocation ratio result;
[0122] like When the load rate of the gas turbine is adjusted again, the specific calculation formula for the adjustment is:
[0123] ,
[0124] in, The load rate of the adjusted gas turbine representing the result of the secondary distribution ratio, Indicates the fuel regulation coefficient of the secondary adjustment of the engine load rate, Indicates the amount of fuel provided by the ethanol tank of the secondary adjustment engine;
[0125] like When the load rate of the gas turbine is adjusted again, the specific calculation formula for the adjustment is:
[0126] ,
[0127] in, The secondary load rate of the adjusted gas turbine is expressed as a result of the secondary distribution ratio.
[0128] Preferably, during the process of production line co-production, if the initial adjustment fails to meet the expected effect, the system will make a secondary adjustment to the load rate of the gas engine. When the secondary distribution ratio initially set by the system is 80%, the control system will adjust the load rate of the gas engine according to this ratio. If the system detects that the load rate still needs to be further optimized, the load rate of the gas engine will be readjusted based on the new data. When it is detected that the actual load rate deviates from the expected 80%, the system will adjust the load rate of the gas engine by increasing or decreasing the amount of fuel from the ethanol tank for optimization. Assuming that the original fuel adjustment coefficient is 0.5 and the amount of fuel provided by the ethanol tank is 1000 liters, the system will make a secondary adjustment based on these data to ensure that the load rate accurately reaches the expected value. Finally, the load rate after the secondary adjustment will be verified again, and the operation of the gas engine will be further adjusted to ensure stable and efficient production line co-production.

[0133] Example 2
[0134] Reference Figure 1 and Figure 2 , which is the second embodiment of the present invention, and this embodiment provides a process regulation and control method based on production line co-production. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.
[0135] During the experimental process to verify the present invention, multiple sensors were deployed in the production line co-production system to monitor the load status of the power generation unit and the ethanol production line co-production unit in real time. At the beginning of the experiment, the system set the load target of the power generation unit to 75% and the load of the ethanol production line co-production unit to 60%, and calculated the synthesis gas allocation ratio through the synthesis gas allocation rule and set it to 85%.
[0136] During the initial adjustment stage, the system automatically adjusted the load rate of the gas turbine according to the set ratio and set the amount of fuel provided by the ethanol tank to 1,200 liters. Experimental data showed that under this setting, the load rate of the power generation unit increased to 70%, but the system detected that the proportion of the synthesis gas volume deviated from the expected level and the actual load rate reached 67%, which was lower than the target load rate.
[0137] The system triggered the secondary adjustment mechanism. In the secondary adjustment stage, the control system adjusted the secondary distribution ratio to 82% according to the feedback, optimized the load rate of the gas turbine again, adjusted the fuel regulation coefficient to 0.6, and increased the amount of fuel provided by the ethanol tank to 1,300 liters. After the secondary adjustment, the load rate of the power generation unit increased to 74%, close to the expected target. After the secondary adjustment, the gap between the actual load rate and the target load rate was narrowed to 3%, which was in line with the expected effect of the system. The system ensured that the load rate reached the set value through the N-time mutual feedback mechanism and maintained a stable production line co-production effect throughout the experiment, thereby verifying the effectiveness and optimization ability of the technical solution. The experimental data adjustment record data is shown in Table 2 below:
[0138] Table 2 Experimental data adjustment record table
[0139] ,
[0140] During the experiment, the load adjustment of the power generation unit and the ethanol production line was tested, and the table shows the load changes of the ethanol unit and the air separation and gasification units at different power generation unit load percentages from 50% to 100%. When the load of the power generation unit gradually increases, the load of the ethanol unit gradually decreases from 100% to 0%, while the load of the air separation and gasification units is maintained at 100% when the load of the power generation unit is low, and gradually decreases to 85% as the power generation load increases. The data reflects the dynamic changes in the load of each device during the load adjustment process, and verifies the effectiveness of the optimized load adjustment mechanism. The comparison between the present invention and the prior art is shown in Table 3 below:

[0143] The present invention is superior to the existing technology in load regulation, and has the advantages of real-time precise adjustment, high flexibility and dynamic optimization. Through the intelligent control system and data feedback mechanism, the present invention can quickly adapt to load changes and adjust the load rate of the gas turbine through ethanol storage tank fuel to ensure effective regulation under full load conditions, thereby improving the efficiency and accuracy of load regulation.
