Description

Technical Field

[0001] The present invention relates to the technical field of temperature control, and in particular to an electric steam generator control system and a use method thereof. Background Art

[0002] The field of temperature control technology encompasses the technical means of measuring, regulating, and maintaining the stability of temperature variables. This technology, which involves multiple disciplines such as thermodynamics, automatic control, and sensor measurement, is widely used in industrial production, environmental regulation, medical equipment, and household appliances. Common methods in temperature control technology include sensor-based data acquisition, the application of control algorithms, and the adjustment of actuators. Sensor elements such as thermocouples and thermistors are used to collect temperature information, microprocessors or dedicated control chips perform data processing, and electric heaters and refrigeration systems act as actuators for temperature regulation. This technical field encompasses sub-directions such as constant temperature control, temperature compensation, and adaptive regulation to ensure that the target environment or equipment operates within a predetermined temperature range.

[0003] The electric steam generator control system is a system used to control the operating status of the electric steam generator so that it generates steam within a set temperature range. This system involves technical aspects such as temperature detection, heating power adjustment, and water level management. Temperature detection typically uses thermocouples or thermistors to measure the internal temperature of the steam generator, and the temperature data is transmitted to a microprocessor for calculation and analysis. Heating power adjustment uses solid-state relays, thyristor rectifiers, or pulse width modulation to control the power output of the electric heating element, thereby precisely controlling the steam temperature. Water level management uses liquid level sensors to monitor the water storage status and, in conjunction with solenoid valves or water pumps, regulates the water inlet to ensure the continuous and stable operation of the steam generator. The core technology of this system lies in real-time monitoring of the steam generator's operating parameters and dynamically adjusting the heating power and water level based on temperature changes to ensure that the steam output meets the set requirements.

[0004] Existing technologies for monitoring the operating status of electric steam generators offer a relatively limited range of monitoring dimensions, lacking in-depth analysis of parameters such as steam flow and pressure change rate. This makes it difficult to precisely adjust heating power to match steam temperature adjustments, resulting in lags or excessive temperature fluctuations. Power distribution often utilizes a fixed compensation mode, making it difficult to respond to changes in steam flow and temperature in real time, limiting the stability and response speed of the steam supply. During steam transportation, the temperature lag between the high- and low-pressure ends is not fully considered, resulting in uneven temperature distribution across the heating area and impacting the thermal energy conversion efficiency at the steam-using end. Regarding abnormality monitoring, traditional methods rely on a single pressure monitoring point, unable to accurately identify blockage trends within the pipeline or abnormal valve openings. This makes it difficult for the heating system to issue early warnings before a failure occurs, potentially leading to unstable operation or delayed fault handling. Heating control strategies lack dynamic optimization methods, and steam supply power adjustment relies primarily on fixed parameter settings, making it difficult to adapt to rapid load changes. This results in decreased heating efficiency and increased energy consumption under certain operating conditions. Summary of the Invention

[0059] The operating status monitoring module extracts the start and stop status of the electric steam generator, water level status, water supply pump start and stop status, heating standby status, and air source heat pump water heater operating status.

[0065] See also Figure 2 , the operation status monitoring module includes:

[0066] The data acquisition submodule obtains the start and stop status of the electric steam generator, water level status, start and stop status of the water supply pump, heating standby status, and operating status of the air source heat pump water heater. It also collects steam flow, pressure, and temperature data, calculates the steam pressure change rate and steam temperature adjustment rate, and obtains the steam state change rate.

[0067] Get the start and stop status of the electric steam generator, call the steam generator start and stop control signal in turn, and judge whether the current steam generator is in operation by reading the on and off status of the control signal in real time. If the control signal is detected to be "on", the start state is recorded, otherwise the stop state is recorded. The water level status is obtained by reading the water level sensor signal. The water level sensor feeds back different electrical signals according to the liquid level height, corresponding to "low water level", "normal water level" and "high water level" respectively. The start and stop status of the make-up water pump is collected by reading the relay output signal. The make-up water pump works when the relay is energized and stops when the power is off. The sampling signal is periodically stored to record the start and stop changes of the make-up water pump. The collection of the heating standby state depends on the on and off status of the heating element. The power supply current of the heating element is detected. If the current is zero, it is judged that the heating is on. The thermal element is in standby mode. The operating status of the air source heat pump water heater is obtained through the water heater control module signal. The water heater start relay is read to determine whether it is in the energized state to determine whether it is running. The steam flow is measured by a flow meter. The flow meter converts the speed of steam through the flow sensor element into an electrical signal and outputs the corresponding flow value. The pressure data is obtained by a pressure sensor. The sensor measures the pressure change in the steam pipeline, outputs a standardized signal and converts it into pressure data. The temperature data is collected by the temperature sensor. The temperature sensor reads the temperature change in the steam pipeline and converts it into a corresponding digital signal. The steam temperature, pressure and flow data are periodically stored through the data acquisition module. The method for calculating the steam pressure change rate is to divide the pressure value difference at adjacent moments by the time interval. The formula is: ,in and are the steam pressure at the current moment and the previous moment respectively, The steam temperature adjustment rate is calculated in a similar way, using the temperature change at adjacent time points divided by the time interval. The formula is: ,in and They represent the steam temperature values ​​at the current moment and the previous moment respectively. After obtaining the steam state change rate, it is stored in the data recording module for subsequent analysis and call.

[0068] The data analysis submodule calls the steam state change rate, identifies the ratio of the steam temperature adjustment rate to the steam pressure change rate, filters out the steam temperature adjustment rates with ratios exceeding the limit, calculates the corresponding steam temperature offset value, and analyzes the degree of steam temperature offset based on the filtered steam temperature adjustment rates and the steam pressure change to obtain the steam temperature offset value.

[0069] The steam temperature offset calculation formula is as follows:

[0070] ;

[0071] in, Represents the calculated steam temperature offset value, Represents the steam temperature adjustment rate calculated at the current moment, Represents the ratio threshold of steam temperature adjustment rate to steam pressure change rate, Represents the steam pressure change rate calculated at the current moment, Represents the time from the first sampling point to the The data of the sampling points are summed. Represents the absolute error value calculated from the ratio of the steam temperature adjustment rate to the steam pressure change rate threshold. Representative The rate of change of steam pressure at a time point, Represents the number of sampled data points in the time window used for calculation:

[0072] To calculate the steam temperature offset , it is necessary to determine the current steam temperature adjustment rate , steam pressure change rate , and the ratio threshold The formula for calculating the steam temperature offset value depends on the above variables and their values ​​for different time windows. The cumulative average error.

[0073] Assume that we have collected the following real monitoring data: Degrees, indicating the steam temperature adjustment rate at the current moment. bar / min, indicating the rate of change of steam pressure at the current moment. , which represents the ratio threshold of the steam temperature adjustment rate to the steam pressure change rate. This value is set based on the system's previous operating experience and engineering requirements.

[0074] Collect data over a period of time (assuming ), the steam temperature adjustment rate at each time point and steam pressure change rate as follows: , , , , , , , , ,

[0075] Calculate the error value at each time point : , , , ,

[0076] Calculate the mean error value:

[0077] ;

[0078] Substitution The calculation formula is:

[0079] ;

[0080] The results show that the temperature adjustment rate of the current steam system deviates from the ideal adjustment model. The specific deviation is degrees, indicating that the actual temperature adjustment is slightly lower than expected, and it may be necessary to adjust the control strategy or conduct a system check to ensure the balance between steam supply and demand.

[0081] The power adjustment evaluation submodule uses the steam temperature offset to calculate the start / stop status indicator of the water supply pump, analyzes the impact of the heating standby state on the steam temperature offset, and generates steam generator operating status data based on the current steam generator operating power and heating standby state.

[0082] Call the steam temperature offset data, combine the start and stop status of the water supply pump to calculate the start and stop status index of the water supply pump, and define the start and stop frequency of the water supply pump as ,in For the water supply pump The number of starts within the time period is calculated, and the influence of the heating standby state on the steam temperature offset is calculated. The statistical analysis method is used to calculate the correlation between the heating standby state and the steam temperature offset. If the heating standby time Exceeding the set threshold , and the steam temperature offset Beyond normal range , it is determined that the heating standby state affects the steam temperature deviation. Based on the current steam generator operating power, the power adjustment demand is analyzed and the operating power adjustment step is set. If the steam temperature deviation is positive and the absolute value exceeds the set range, the operating power will be reduced. If the steam temperature deviation is negative and the absolute value exceeds the set range, increase the operating power , and finally generates the steam generator operating status data and stores it in the system control module.

[0083] See also Figure 2 , the dynamic power allocation module includes:

[0084] The ratio calculation submodule obtains the steam generator operating status data, calls the steam pressure change rate, steam flow adjustment rate, and steam temperature adjustment rate, calculates the ratio of the steam flow increase rate to the steam temperature decrease rate, and obtains the steam temperature flow ratio;

[0085] After obtaining the steam generator operating status data, the steam pressure change rate, steam flow adjustment rate and steam temperature adjustment rate are called in sequence. First, to obtain the steam pressure change rate, the pressure sensor data in the steam pipeline is called, and the pressure values ​​at multiple moments from the current time point are traced back, the pressure change at adjacent time points is calculated, and divided by the corresponding time interval. Each calculated change rate data will be stored in the ratio calculation module for subsequent calls. If the pressure change rate at a certain moment is detected to be zero or abnormal, the data point will be marked as invalid and the calculation of the point will be skipped. The steam flow adjustment rate is obtained in a similar way. The steam flow data at the current time point is read through the flow meter, and the change between the current flow and the flow at the previous moment is calculated. The flow adjustment rate is calculated based on the time interval. At the same time, the system will identify the overall trend of the flow adjustment after comparing the data at multiple time points, and determine whether the flow is continuously rising, falling or fluctuating. If it is detected that the flow adjustment rate is zero or the change range is extremely small for multiple consecutive time points, the flow adjustment rate for this period is marked as abnormal. The steam temperature adjustment rate is calculated by reading the temperature sensor data, extracting the steam temperature values ​​at the current moment and multiple historical moments, calculating the temperature change at each moment and combining the time interval to obtain the temperature adjustment rate, and setting the temperature reduction rate to a negative value. If the temperature adjustment rate at the current time point is abnormal, for example, the temperature fluctuates violently or suddenly exceeds the preset threshold, the data point is marked as abnormal and stored in the abnormal database. Finally, when calculating the ratio of the steam flow increase rate to the steam temperature decrease rate, the system takes a positive value for the flow adjustment rate and an absolute value for the temperature adjustment rate. If the temperature adjustment rate is zero, the ratio calculation is invalid, and the system automatically skips the data point and records the abnormal point in the data storage module for subsequent data analysis. Finally, the steam temperature flow ratio is obtained and stored in the ratio calculation module for subsequent use.

[0086] The power demand screening submodule calls the steam temperature-flow ratio, screens the power compensation demand values ​​whose ratios exceed the threshold, calculates the dynamic compensation power interval corresponding to the power compensation demand value, analyzes the corresponding relationship between the compensation power interval and the steam pressure change rate, and obtains the dynamic compensation power interval adjustment amount;

[0087] The steam temperature flow ratio data is called, and the currently calculated ratio is compared with the set threshold range. The power compensation demand value exceeding the threshold is screened out, and the historical data stored in the ratio calculation module is read. The changing trend of the steam temperature flow ratio is analyzed. If the ratio deviates from the set threshold for multiple consecutive time points, the system records the changing trend and calculates the power compensation value required under the current working conditions. The calculation of the power compensation demand value is based on the deviation degree of the steam temperature flow ratio. If the deviation is large, the power compensation demand value is increased accordingly. If the deviation is small, the power compensation demand value is reduced accordingly. After the calculation is completed, the system stores the compensation demand value in the data module and uses it for subsequent dynamic compensation power interval calculations. The power interval is calculated by multiplying the power compensation demand value by the adjustment coefficient, where the adjustment coefficient is calculated based on the steam temperature flow ratio. The abnormal degree of the ratio is dynamically set. If the ratio is significantly higher than the set upper limit, the adjustment coefficient takes a lower value to reduce the compensation power. If the ratio is significantly lower than the set lower limit, the adjustment coefficient takes a higher value to increase the compensation power. After calculating the dynamic compensation power interval, the system further analyzes the relationship between the power interval and the steam pressure change rate, calls the pressure change rate data, and determines whether the current operating condition is in the low pressure, medium pressure or high pressure interval. If it is in the low pressure interval, the low pressure compensation strategy is adopted to adjust the compensation power range to adapt to the needs of the low pressure state. If it is in the medium pressure interval, the standard compensation strategy is adopted. If it is in the high pressure interval, the compensation power is appropriately reduced to prevent the steam system from overloading. Finally, the system calculates the dynamic compensation power interval adjustment amount and stores it in the power parameter adjustment module for subsequent power allocation.

[0088] The power parameter correction submodule calls the dynamic compensation power interval adjustment amount, combines the current heating power allocation parameter, calculates the corrected heating power allocation value, and outputs the heating power allocation parameter;

[0089] The corrected calculation formula for the heating power distribution value is:

[0090] ;

[0091] in, Represents the corrected heating power distribution value, represents the current baseline heating power allocation value, Represents the adjustment coefficient, which is used to adjust the sensitivity of the power. Represents the time from the first sampling point to the The data of the sampling points are summed. Representative The dynamic compensation power adjustment value at a time point, Represents the weight coefficient, which adjusts the relationship between the current heating power and the compensation value. Representative The current heating power value at a time point, represents another adjustment coefficient used to smooth the fluctuation of the corrected power. Represents the dynamic compensation power interval adjustment calculated at the current moment, Represents the heating power at the current moment, Represents the number of sampled data points in the time window used for calculation, Indicates taking the cube root of the difference between the compensation value and the current power:

[0092] This formula is used to calculate the corrected heating power distribution value The specific calculation process is as follows:

[0111] ;

[0112] The results show a slight increase in the corrected heating power, reflecting a minor adjustment to the base power based on the dynamic compensation power adjustment. This indicates that the system maintains the original heating power while making subtle optimization adjustments based on actual operating conditions to cope with possible short-term changes in power demand.

[0113] See also Figure 2 , the temperature and pressure compensation module includes:

[0114] The transfer delay calculation submodule obtains the heating power distribution parameters, calls the high-pressure end steam temperature change rate and the low-pressure end steam temperature lag time, calculates the steam transfer delay index, and obtains the steam transfer delay coefficient;

[0115] The high-pressure end steam temperature change rate and the low-pressure end steam temperature lag time are called sequentially. First, the heating power allocation parameters are read, and the current heating power is extracted from the steam generator's heating module. The steam temperature data for the corresponding time period is matched to obtain the temperature change rate of the steam generator's high-pressure end. The temperature change rate is calculated by taking the ratio of the high-pressure end temperature change to the time interval at adjacent moments and storing it in the data processing module. The low-pressure end steam temperature lag time is calculated based on the data from the pressure sensor and temperature sensor. First, the high-pressure end steam temperature data is called to detect the temperature change trend. Then, the temperature data for the same time period is detected at the low-pressure end, and the lag time of the temperature response is calculated. That is, the time alignment point between the high-pressure end temperature change and the low-pressure end temperature change is found, the time difference between the two is measured, and the time difference data is stored. When calculating the steam transfer delay index, the high-pressure end temperature change rate and the low-pressure end temperature lag time are combined. The steam transfer delay index is obtained by dividing the lag time by the high-pressure end temperature change rate. The data for multiple time periods are smoothed to eliminate data noise. Finally, the steam transfer delay coefficient is obtained and stored in the delay calculation module for subsequent use.

[0116] The compensation amount screening submodule calls the steam transfer delay coefficient, screens the steam temperature adjustment compensation amount, analyzes the pressure gradient change rate in the steam flow valley area, calculates the temperature change interval value of the steam transmission path, evaluates the steam transmission temperature index based on the steam temperature adjustment compensation amount and the pressure gradient change rate, and obtains the steam transmission temperature deviation interval;

[0117] Compare the currently calculated delay coefficient with the set normal range, screen out the steam temperature adjustment compensation amount, read historical data, analyze the change trend of the delay coefficient, if the delay coefficient continues to exceed the set range at multiple time points, the system will record the abnormal data and calculate the corresponding steam temperature adjustment compensation amount. When calculating the compensation amount, set the compensation intensity according to the size of the transmission delay coefficient. If the delay coefficient is large, the compensation amount will increase, and if the delay coefficient is small, the compensation amount will decrease. The calculated compensation amount is stored in the data module and used for subsequent steam transmission temperature evaluation. When analyzing the pressure gradient change rate in the steam flow valley area, call the flow The system uses the flow rate data to identify the flow valley section and calculate the pressure change rate in the section. If the pressure change rate is low, the section is marked as a low-speed pressure gradient area. If the pressure change rate is high, the section is marked as a high-speed pressure gradient area. Combined with the temperature change data of the steam transmission path, the temperature change interval value is calculated. Based on the steam temperature adjustment compensation amount and the pressure gradient change rate, the system further evaluates the steam transmission temperature index. If the compensation amount is high and the pressure gradient change rate is low, the temperature transmission parameters are adjusted to ensure the rationality of the temperature regulation. Finally, the steam transmission temperature deviation interval is obtained and stored in the data processing module.

[0118] The pressure regulation correction submodule calls the steam delivery temperature deviation interval, calculates the pressure regulation compensation value correction amount, and generates the temperature and pressure adjustment parameters in combination with the pressure regulation compensation value;

[0119] First, compare the upper and lower limits of the temperature deviation range to determine whether the current temperature deviation exceeds the normal range. If the deviation exceeds the set range, calculate the pressure regulation compensation value correction amount, call the pressure regulation compensation value, and calculate the corrected pressure regulation compensation value according to the size of the temperature deviation range. If the temperature deviation is too large, increase the compensation value. If the temperature deviation is small, reduce the compensation value. The calculated correction amount is stored in the data module and combined with the pressure regulation parameters of the current system to generate the temperature and pressure adjustment parameters and store them in the system control module for subsequent steam delivery pressure and temperature regulation.

[0120] See also Figure 2 , the abnormal monitoring and early warning module includes:

[0121] The pressure difference change calculation submodule obtains the temperature and pressure adjustment parameters, calls the main steam pipeline inlet pressure and branch outlet pressure, calculates the pressure difference change rate between the two, filters out the pressure difference change rate exceeding the limit value, and obtains the pressure difference change result;

[0122] First, the system extracts real-time pressure data from the main steam pipe inlet from the steam pipe pressure sensor, and synchronously reads the outlet pressure data of the branch pipe to calculate the instantaneous pressure difference between the inlet and outlet. Subsequently, the system extracts the pressure difference values ​​at different time points in sequence and divides the pressure difference change between the two time points by the corresponding time interval to obtain the pressure difference change rate. During the calculation process, if an abnormality is detected in the inlet or outlet pressure data, such as no change or abnormal fluctuation of the pressure value at multiple consecutive time points, the system marks the data point as invalid and stores it in the abnormal data marking library. When filtering out the pressure difference change rate exceeding the limit value, the system calls the set pressure difference change rate threshold. If the currently calculated pressure difference change rate is higher than the set upper limit or lower than the set lower limit, the system records the abnormal change rate and stores it in the abnormal data recording module. At the same time, trend analysis is performed on the data at multiple consecutive time points. If the pressure difference change rate is found to be excessive for a long time, the trend data is further recorded and the average rate of the trend change is calculated. Finally, the system stores the filtered pressure difference change rate data and uses it as the pressure difference change result for subsequent sub-modules to call.

[0123] The pipeline anomaly analysis submodule calls the pressure difference change results, screens the pipeline blockage judgment value and the pressure drop trend judgment value, calculates the change rate of the pipeline blockage judgment value, evaluates the degree of deviation of the pressure drop trend, analyzes the pipeline abnormal state, calls the valve opening data, calculates the valve opening fluctuation rate, and based on the ratio of the fluctuation rate to the pressure drop trend change rate, combined with the pressure drop trend judgment value, evaluates the pipeline transportation stability and obtains the pipeline abnormal state parameters;

[0124] First, the system extracts historical data and compares the current pipeline pressure difference change rate with the standard pressure difference rate range under normal operating conditions. If the pressure difference change rate increases abnormally, it is determined that there may be a risk of pipeline blockage. If the pressure difference change rate decreases abnormally, there may be a pipeline leakage or unstable gas supply problem. The system sets the pipeline blockage judgment value and calculates the change rate of the judgment value. It calls historical time period data to calculate the pipeline blockage judgment value at different times, and calculates the change rate of the judgment value based on the changes before and after. If the change rate continues to increase, it is considered that the pipeline blockage trend is increasing. If the change rate continues to decrease, the pipeline blockage risk is reduced. At the same time, the system analyzes the pressure drop trend, calculates its offset, calls historical pressure data, analyzes the pressure change rate at multiple time points, and calculates its offset value relative to the set standard pressure change trend. If the pressure drops If the trend deviates from the normal range, the trend is further marked as abnormal and stored in the data module. Subsequently, the system analyzes the abnormal state of the pipeline. Combined with the pipeline pressure drop trend and the change rate of the blockage judgment value, the system further evaluates the current operating state of the pipeline and calls the valve opening data. The valve opening data at the current moment is extracted from the steam pipeline control system, and the valve opening change value at the previous and next time points is calculated. The valve opening fluctuation rate is calculated. If the fluctuation rate is high and the pressure drop trend change rate is large, it indicates that the flow state inside the pipeline is unstable. If the fluctuation rate is low and the pressure drop trend change rate is small, the pipeline transportation state is relatively stable. Finally, the system evaluates the pipeline transportation stability based on the ratio of the valve opening fluctuation rate to the pressure drop trend change rate, combined with the pressure drop trend judgment value, and stores the evaluated pipeline abnormal state parameters for use by subsequent modules.

[0125] The heating abnormality warning submodule calls pipeline abnormality state parameters, calculates the impact of steam flow changes on pressure stability, screens abnormal state judgment signals, calculates heating abnormality level parameters, establishes abnormality warning trigger thresholds, and generates steam heating abnormality warning data based on pressure gradient change characteristics;

[0126] First, the system analyzes the impact of steam flow changes on pressure stability, extracts steam pipeline flow sensor data, calculates the change in steam flow at different time points, and analyzes flow fluctuation trends in combination with historical data. If the flow fluctuation is large, it may have a greater impact on pressure stability. If the flow fluctuation is small, the impact is weak. Subsequently, the system screens the abnormal state judgment signal, calls the set abnormal state threshold, and compares the current pipeline abnormal state parameter with the set standard value. If the current abnormal state parameter exceeds the set range, the abnormal state judgment signal is triggered and stored in the abnormal state recording module. Next, the system calculates the heating abnormality level parameter, calls historical data, and calculates the current abnormal state. The deviation of the previous abnormal state relative to the historical average state, and the duration of the abnormal state are combined to divide the abnormal level. If the abnormal state lasts for a short time and the deviation is small, it is judged as a low-level abnormality. If it lasts for a long time and the deviation is large, it is judged as a high-level abnormality. Finally, the system establishes an abnormal warning trigger threshold, and combined with the pressure gradient change characteristics, the system calculates the pressure gradient change rate at different time points and analyzes the pressure change trend. If the current pressure gradient change exceeds the set normal range, the system adjusts the abnormal warning threshold to adapt to the changes under different working conditions. Finally, the system generates steam heating abnormal warning data and stores it in the warning system for use by the control module.

[0127] See also Figure 2 , the operation control optimization module includes:

[0128] The start-stop control submodule obtains steam heating abnormality warning data, calls the electric steam generator automatic control system, calculates the steam generator start-stop control index, screens the start-stop control range, and obtains the steam generator start-stop control parameters;

[0129] First, the steam generator automatic control system is called to extract the current operating status data, identify heating pressure fluctuations, steam temperature anomalies, or flow deviations in the abnormal warning data, and calculate the steam generator start-stop control index. The system calls historical data, analyzes the start-stop status of the steam generator over the past period of time, and calculates the corresponding power demand changes. Combined with the steam temperature fluctuation range in the abnormal warning data, the temperature offset is calculated, and the start-stop control index range is delineated based on the temperature offset. If the temperature offset is small, the start-stop control adjustment range is correspondingly reduced. If the temperature offset is large, the control range is expanded. Subsequently, the system screens the start-stop control range and calls the set start-stop threshold to determine whether the current steam generator operating status needs to be adjusted. If the deviation value in the steam heating abnormal warning data exceeds the set normal operating range and the pressure or temperature continues to be unstable, the system determines that the current state requires start-stop control and sets the start-stop delay time based on the steam generator's operating cycle. Finally, the steam generator start-stop control parameters are calculated and stored for subsequent sub-module calls.

[0130] The power adjustment submodule calls the steam generator start and stop control parameters, retrieves the steam supply power adjustment value, measures the electric steam generator heating state adjustment value, calculates the steam supply adjustment interval value, and based on the ratio of the steam supply adjustment interval to the heating state adjustment value, screens the power adjustment range and obtains the steam supply adjustment interval based on the operating status.

[0131] First, retrieve the current steam supply power adjustment, extract the steam generator power distribution data, and compare the start-stop control parameters to determine whether the current power needs to be adjusted. When calculating the heating state adjustment value of the electric steam generator, the system calls historical data to calculate the heating state changes of the current steam generator under different temperature offset conditions. Combined with the current load demand, calculate the appropriate heating adjustment amount. If the current temperature offset is large, increase the power adjustment range. If the temperature offset is small, reduce the adjustment range. At the same time, calculate the steam supply adjustment interval value. Combine the current steam supply and historical supply trends to set the adjustment range. If the supply exceeds the expected range, appropriately shrink the adjustment. Interval. If the supply is lower than the demand, the adjustment interval is expanded. Subsequently, the system calculates the power adjustment range based on the ratio of the steam supply adjustment interval value to the heating state adjustment value. If the ratio is large, it indicates that the steam supply is highly dependent on the heating power and requires more precise power adjustment. If the ratio is small, the power adjustment range can be appropriately reduced. Combined with the operating status data of the steam generator, the system evaluates whether the current operating mode is suitable for power adjustment. If the current operating load is high and the pressure is stable, the power adjustment range is appropriately increased. If the operating load is low and the temperature fluctuates greatly, the power adjustment range is appropriately reduced. Finally, the steam supply adjustment interval is stored for subsequent sub-modules to call.

[0132] The flow optimization submodule calls the steam supply adjustment interval, analyzes the impact of steam supply adjustment on flow distribution, optimizes the steam transmission path, calculates the adjusted flow distribution value, and generates the electric steam generator operation control plan based on the power adjustment range;

[0133] First, the impact of steam supply adjustment on flow distribution is analyzed. Steam pipeline flow sensor data is extracted, and the flow distribution before and after adjustment is compared. The flow deviation before adjustment and the degree of flow balance after adjustment are calculated. If the flow distribution of each branch pipeline is more balanced after the flow adjustment, the adjustment is considered reasonable; otherwise, further optimization is required. When optimizing the steam transmission path, the system calls the steam pipeline flow data, analyzes the flow fluctuations of different pipelines, and sets optimization goals. If the flow load of a pipeline is too high, the steam flow direction needs to be redistributed to reduce the flow load of the pipeline. If the flow of a pipeline is low, the flow transmission is appropriately increased. When calculating the adjusted flow distribution value, the system recalculates the flow distribution ratio based on the current steam supply adjustment range and the demand of each pipeline, and compares the flow balance before and after adjustment. If the flow balance is improved after adjustment, the optimized flow distribution value is stored. Combined with the power adjustment range, the system analyzes the impact of steam power adjustment on flow distribution. If the power adjustment range is large, the flow optimization plan needs to be appropriately adjusted to adapt to the power change. Finally, the electric steam generator operation control plan is generated and stored in the system control module for the steam generator to execute control instructions.
