Description

Technical Field

[0001] The present invention relates to the technical field of gas energy supply equipment operation control, and in particular to an optimization control method and system for gas energy supply equipment operation. Background Art

[0002] With the transformation of energy structures and the improvement of industrial automation levels, gas-fired energy supply equipment (such as natural gas boilers, gas turbines, distributed energy stations, etc.) is increasingly being used in industrial production, residential heating, and power generation. However, gas leakage, pressure imbalance, and energy loss have become core bottlenecks restricting the efficient operation of equipment. Gas-fired energy supply equipment must operate at a stable pressure, and pressure fluctuations will reduce combustion efficiency. After the equipment triggers a protective shutdown due to pressure imbalance or leakage, the restart process consumes additional energy. Frequent starts and stops and pressure fluctuations will increase the thermal stress of the equipment and shorten the life of components.

[0003] The existing method is mainly based on real-time monitoring of gas pipeline pressure through a pressure balancing valve. The pressure balancing valve senses the pressure difference through the diaphragm and automatically drives the valve core to move, thereby balancing the pressure. The gas pipeline pressure is monitored in real time through the pressure balancing valve. Once the pressure exceeds the preset range, the valve will automatically adjust the opening to ensure pressure stability.

[0004] For example, the gas transmission and distribution monitoring system disclosed in the invention patent with publication number CN103324184B includes a valve position transmitter, a pressure regulator, a valve position transmitter, a controller, a flow meter, and a power supply communication box. The pressure regulator has an upper chamber, a lower chamber, a diaphragm, a valve core, an air inlet pipe, and an air outlet pipe. The valve position transmitter is installed on the top of the pressure regulator, detects the valve position opening of the valve core, and outputs a valve position opening signal loaded with the valve position opening. The controller receives the valve position opening signal, detects the inlet pressure of the pressure regulator, detects the outlet pressure of the pressure regulator, and calculates the instantaneous flow value of the pressure regulator based on the valve position opening, inlet pressure, and outlet pressure. The flow meter is installed on the air inlet pipe to measure the total flow value flowing through the pressure regulator. The power supply communication box includes a communication module, which is used to send the instantaneous flow value and the total flow value to the remote control center.

[0005] For example, the invention patent with announcement number CN102778880B discloses a coordinated control method for an integrated coal gasification combined cycle power plant based on energy balance, which includes: collecting field signals, calculating the heat signal of the gasifier and the energy signal of the gas turbine, adjusting the gasifier and the gas turbine, realizing decoupling control of the power island and the gasification island, synchronously controlling the gas turbine power and the gas pressure before the regulating valve, making the heat signal track the energy signal, and realizing coordinated control of the integrated coal gasification combined cycle power plant.

[0006] However, in the process of implementing the technical solutions of the invention in the embodiments of the present application, the present application found that the above technology has at least the following technical problems:

[0007] In the existing technology, gas leakage directly leads to fuel loss, destroying the pressure balance of the gas energy supply equipment, resulting in increased energy loss, which may cause insufficient output of the gas energy supply equipment or frequent start and stop. Due to insufficient pressure balance of the gas energy supply equipment, the control accuracy of the gas energy supply equipment operation is low. Summary of the Invention

After the leakage and pressure stability monitoring is qualified, the gas energy supply equipment operation qualification monitoring is performed to determine whether to perform gas energy supply qualification optimization, thereby achieving improved operating efficiency of the gas energy supply equipment.

[0020] The technical solution in the embodiment of the present application is to solve the problem of low control accuracy of the operation of the gas energy supply equipment due to insufficient pressure balance of the gas energy supply equipment. The overall idea is as follows:

[0021] Gas leakage interference monitoring is carried out to determine whether leakage and pressure stability monitoring should be carried out. If leakage and pressure stability monitoring is carried out, whether leakage and pressure stability optimization should be carried out is determined based on the obtained leakage and pressure stability data. After the leakage and pressure stability monitoring is qualified, the gas energy supply equipment operation qualification monitoring is carried out to determine whether gas energy supply qualification optimization should be carried out, thereby achieving the effect of improving the operating efficiency of the gas energy supply equipment.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, it is a flow chart of an optimization control method for the operation of gas energy supply equipment provided in an embodiment of the present application, the method comprising the following steps: gas leakage interference monitoring: performing gas leakage interference monitoring to determine whether to perform leakage and pressure stability monitoring, the gas leakage interference monitoring is used to evaluate the impact of gas leakage on the combustion quality of the gas energy supply equipment, and the leakage and pressure stability monitoring is used to evaluate the pressure balance of the gas energy supply equipment; leakage and pressure stability optimization determination: if leakage and pressure stability monitoring is performed, then based on the obtained leakage and pressure stability data, it is determined whether to perform leakage and pressure stability optimization, otherwise a gas leakage level 1 risk prompt is sent and the gas energy supply equipment operation qualification monitoring is performed, and the leakage and pressure stability optimization is used to improve the pressure balance qualification of the gas energy supply equipment; gas energy supply equipment operation qualification monitoring: after the leakage and pressure stability monitoring is qualified, the gas energy supply equipment operation qualification monitoring is performed to determine whether to perform gas energy supply qualification optimization, the gas energy supply equipment operation qualification monitoring is used to evaluate the qualification of the operation of the gas energy supply equipment, and the gas energy supply qualification optimization is used to improve the operation qualification of the gas energy supply equipment.

[0024] like Figure 2As shown, it is a structural diagram of the optimization control system for the operation of the gas energy supply equipment provided by the embodiment of the present application, the optimization control system for the operation of the gas energy supply equipment provided by the embodiment of the present application, the gas leakage interference monitoring module, the leakage and pressure stability optimization judgment module and the gas energy supply equipment operation qualification monitoring module: wherein the gas leakage interference monitoring module is used to perform gas leakage interference monitoring to determine whether to perform leakage and pressure stability monitoring, the gas leakage interference monitoring is used to evaluate the impact of gas leakage on the combustion quality of the gas energy supply equipment, the leakage and pressure stability monitoring is used to evaluate the pressure balance of the gas energy supply equipment; the leakage and pressure stability optimization judgment module is used to If leakage and pressure stability monitoring is performed, it is determined whether leakage and pressure stability optimization is performed based on the obtained leakage and pressure stability data. Otherwise, a first-level gas leakage risk prompt is sent and the gas energy supply equipment operation qualification monitoring is performed. Leakage and pressure stability optimization is used to improve the pressure balance qualification of the gas energy supply equipment; the gas energy supply equipment operation qualification monitoring module is used to perform gas energy supply equipment operation qualification monitoring after the leakage and pressure stability monitoring is qualified to determine whether gas energy supply qualification optimization is performed. The gas energy supply equipment operation qualification monitoring is used to evaluate the qualification of the operation of the gas energy supply equipment, and the gas energy supply qualification optimization is used to improve the operation qualification of the gas energy supply equipment.

[0025] In this embodiment, if Figure 3 As shown in FIG, it is a thought diagram of the optimization control method for the operation of the gas energy supply equipment provided in the embodiment of the present application, such as Figure 4 As shown, it is a topological architecture diagram provided by an embodiment of the present application; a thermal power drop value is obtained by performing gas leakage interference monitoring. If the thermal power drop value is within a preset thermal power drop range, a first-level gas leakage risk prompt is sent, otherwise a second-level gas leakage risk prompt is sent, and leakage and pressure stability monitoring is performed to obtain leakage and pressure stability characteristic values. When the monitored leakage and pressure stability characteristic values ​​are not greater than the preset leakage and pressure stability values, leakage and pressure stability optimization is performed. The leakage and pressure stability optimization includes lowering the valve opening setting and increasing the valve opening setting. Otherwise, the gas energy supply equipment operation qualification is monitored to obtain the gas energy supply equipment operation qualification quantitative value. When the monitored gas energy supply equipment operation qualification quantitative value is not greater than the preset energy supply equipment operation qualification value, an operation failure prompt is sent, and gas energy supply qualification optimization is performed. The gas energy supply qualification optimization includes reducing the burner injection angle setting and increasing the burner injection angle setting. Otherwise, an operation qualification prompt is sent.

[0026] Through the interaction of gas leakage interference monitoring, leakage and pressure stability optimization judgment, and gas supply equipment operation qualification monitoring, the operation of gas supply equipment is made safer, more stable, and more efficient, and excessive wear and fatigue damage of gas supply equipment caused by gas leakage is reduced, thereby achieving the improvement of the operating efficiency of gas supply equipment.

[0027] Furthermore, gas leakage interference monitoring is performed to determine whether leakage and pressure stability monitoring should be performed. The specific process is as follows: the thermal power drop value of the gas energy supply equipment within a preset time period is obtained, and the monitored thermal power drop value is compared with the preset thermal power drop range obtained from the database; if the thermal power drop value is within the preset thermal power drop range, a first-level gas leakage risk warning is sent; if the thermal power drop value is not within the preset thermal power drop range, a second-level gas leakage risk warning is sent, and leakage and pressure stability monitoring is performed; the thermal power drop value is represented by the difference between the thermal power of the final gas energy supply equipment monitored by the gas turbine flowmeter during the preset time period and the thermal power of the initial gas energy supply equipment; the thermal power drop value is used to reflect the impact of gas leakage on the combustion quality of the gas energy supply equipment.

[0028] Specifically, leakage and pressure stability monitoring includes obtaining leakage and pressure stability characteristic values ​​and pressure stability judgment; leakage and pressure stability characteristic values ​​are obtained by quantifying leakage and pressure stability parameters and preset leakage and pressure stability parameters, and leakage and pressure stability quantification includes energy supply pressure and stability quantification, exhaust temperature and stability quantification, valve stem displacement and stability quantification and comprehensive stability quantification.

[0029] The energy supply pressure and stability quantification means that the average energy supply pressure deviation value and the preset average energy supply pressure deviation value are analyzed to obtain the energy supply pressure-stability quantification value, which is used to reflect the quantitative effect of the average energy supply pressure deviation value on the pressure balance of the gas energy supply equipment. Among them, the proportion analysis is to perform ratio operation. Specifically, the expression of the energy supply pressure-stability quantification value is: F represents the number of the preset time period, K represents the total number of preset time periods, S 1 (F) represents the energy supply pressure-stable quantitative value of the Fth preset time period, ΔYL(F) represents the average energy supply pressure deviation value of the Fth preset time period, ΔYL(0) represents the preset average energy supply pressure deviation value, and the average value corresponding to the absolute value of the difference between the initial and final state pressures of the preset position points of the energy supply pipeline of the gas energy supply equipment within the preset time period monitored by the pressure sensor is used as the average energy supply pressure deviation value. The units of the average energy supply pressure deviation value and the preset average energy supply pressure deviation value are both Pascal.

[0030] Exhaust temperature and stability quantification represent the exhaust temperature-stability quantification value obtained by analyzing the proportion of the average exhaust temperature and the preset average exhaust temperature. It is used to reflect the quantitative effect of the average exhaust temperature on the pressure balance of the gas energy supply equipment. Specifically, the expression of the exhaust temperature-stability quantification value is: S 2 (F) represents the exhaust temperature-stable quantitative value of the Fth preset time period, PW(F) represents the average exhaust temperature of the Fth preset time period, PW(0) represents the preset average exhaust temperature, and the average value corresponding to the absolute value of the final state temperature of the preset position point of the exhaust port of the gas power supply equipment during the preset time period monitored by the thermocouple temperature sensor is used as the average exhaust temperature. The units of the average exhaust temperature and the preset average exhaust temperature are both degrees Celsius.

[0031] The valve stem displacement and stability quantification represents the ratio analysis of the valve stem displacement and the preset valve stem displacement to obtain the valve stem displacement-stability quantification value, which is used to reflect the quantitative effect of the valve stem displacement on the pressure balance of the gas energy supply equipment. Specifically, the expression of the valve stem displacement-stability quantification value is: S 3 (F) represents the valve stem displacement-stable quantitative value of the Fth preset time period, QH(F) represents the valve stem displacement of the Fth preset time period, QH(0) represents the preset valve stem displacement, and the displacement of the pressure balancing valve in the preset time period is monitored by a laser displacement sensor as the valve stem displacement. The units of the valve stem displacement and the preset valve stem displacement are both millimeters.

[0032] Comprehensive stability quantification means coupling the leakage and pressure stability data with the corresponding leakage and pressure stability adjustment values ​​to perform weighted operations, and then performing negative correlation quantification to obtain leakage and pressure stability characteristic values, where negative correlation quantification is the inverse operation; the leakage and pressure stability characteristic values ​​are used to reflect the comprehensive quantitative effect of the leakage and pressure stability parameters and the preset leakage and pressure stability parameters on the pressure balance of the gas energy supply equipment.

[0033] Among them, the leakage and pressure stability characteristic values ​​are obtained by the following method:

[0034]

[0035] Where S(F) represents the leakage and pressure stability characteristic value of the Fth preset time period, A1 represents the preset exhaust temperature-stable adjustment value, A2 represents the preset energy supply pressure-stable adjustment value, and A3 represents the preset valve stem displacement-stable adjustment value.

[0036] In summary, the leakage and pressure stability data include the energy supply pressure-stable quantitative value, the exhaust temperature-stable quantitative value and the valve stem displacement-stable quantitative value, and the leakage and pressure stability data all consider the situation greater than 0; the leakage and pressure stability parameters include the average energy supply pressure deviation value, the average exhaust temperature and the valve stem displacement; the preset leakage and pressure stability parameters include the preset average energy supply pressure deviation value, the preset average exhaust temperature and the preset valve stem displacement; the leakage and pressure stability adjustment value includes the preset exhaust temperature-stable adjustment value, the preset energy supply pressure-stable adjustment value and the preset valve stem displacement-stable adjustment value, which are used to reflect the degree of influence of the leakage and pressure stability data on the leakage and pressure stability characteristic value.

[0037] It should be added that before the design of the optimization control method for the operation of gas power supply equipment provided in this application, a database for storing various setting data is established, which includes but is not limited to a preset average power supply pressure deviation value, a preset average exhaust temperature and a preset valve stem displacement, etc., and the various numerical values ​​are directly set by technical personnel; for example, the preset leakage and pressure stability parameters are represented by the average value of the leakage and pressure stability parameters in the historical time period; by inputting the real-time leakage and pressure stability data into the corresponding mapping group, the corresponding leakage and pressure stability adjustment value can be obtained; the mapping group is obtained from the database and contains a mapping set, which is used to reflect the mapping relationship between the leakage and pressure stability data and the corresponding leakage and pressure stability adjustment value, wherein the mapping relationship in the mapping set can be a one-to-one correspondence or a many-to-one relationship; for example, the value range of the leakage and pressure stability adjustment value is 0-1.

[0038] In this embodiment, further analysis of the leakage and pressure stability data yields a leakage and pressure stability characteristic value. Larger leakage and pressure stability data indicates a greater quantification effect of the average supply pressure deviation, the average exhaust temperature, and the valve stem displacement on the pressure balance of the gas energy supply equipment, leading to a smaller leakage and pressure stability characteristic value. In summary, in this embodiment, the leakage and pressure stability data and the leakage and pressure stability characteristic value are negatively correlated.

[0039] The leakage and pressure stability parameters monitored in this embodiment do not exist in isolation, but have interrelated characteristics, and correlation analysis is required to describe their joint effects. The larger the average energy supply pressure deviation value, the more likely the flow state of the gas in the gas energy supply equipment may be abnormal. This abnormal flow will affect the combustion process, and the gas combustion speed will increase, which may cause the average exhaust temperature to rise. The larger the average energy supply pressure deviation value, the greater the valve stem displacement and the increase in gas intake volume. The change in average exhaust temperature will affect the heat load and pressure distribution inside the equipment. When the average exhaust temperature is higher, the thermal stress inside the gas energy supply equipment increases, which may lead to uneven pressure distribution, and thus may lead to greater valve stem displacement. By analyzing the comprehensive impact of the parameters, an accurate assessment of the pressure balance of the gas energy supply equipment is achieved, thereby improving the operating efficiency of the gas energy supply equipment.

[0040] Furthermore, the pressure stability determination includes the pressure response time determination and the pressure stability determination: the specific process of the pressure response time determination is as follows: monitoring the response time of the pressure balancing valve; judging whether to optimize the leakage and pressure stability based on the pressure balancing valve response time and the preset pressure balancing valve response range obtained from the database, wherein the preset pressure balancing valve response range is set in advance by the preset personnel; if the monitored pressure balancing valve response time is within the preset pressure balancing valve response range, a valve response qualified prompt is sent; if the monitored pressure balancing valve response time is not within the preset pressure balancing valve response range, a valve response unqualified prompt is sent and an alarm prompt is sent; the specific process of the pressure stability determination is as follows: based on the leakage and pressure stability characteristic values ​​and the preset leakage obtained from the database The leakage and pressure stability value is used to determine whether to optimize the leakage and pressure stability, wherein the preset leakage and pressure stability value is represented by the average value of the leakage and pressure stability characteristic value of the historical time period; if the leakage and pressure stability characteristic value is not greater than the preset leakage and pressure stability value, a pressure stability unqualified prompt is sent, and the leakage and pressure stability optimization is performed; if the leakage and pressure stability characteristic value is greater than the preset leakage and pressure stability value, a pressure stability qualified prompt is sent, and the gas energy supply equipment operation qualification monitoring is performed; the leakage and pressure stability characteristic value is used to reflect the pressure balance of the gas energy supply equipment in the preset time period, wherein the pressure balancing valve response time is obtained by monitoring the timer from the time the pressure balancing valve receives the control signal to the time its output pressure reaches the preset target value in the preset time period.

[0041] In this embodiment, the pressure balancing valve response time reflects how quickly the valve adjusts to pressure changes. By comparing the pressure balancing valve response time with the preset pressure balancing valve response range, it is helpful to promptly detect abnormal conditions such as slow valve response or failure; the pressure response time judgment and the pressure stability judgment work together to help effectively reduce the system operation risk, and can ensure that the system can monitor the operation qualification of the gas energy supply equipment under stable pressure, avoid problems such as frequent start and stop of equipment and reduced efficiency due to pressure fluctuations, improve the overall operation stability and reliability of the system, and thus achieve the effect of improving the operating efficiency of the gas energy supply equipment.

[0042] Furthermore, the specific process of optimizing leakage and pressure stability is as follows: compare the monitored leakage and pressure stability characteristic values ​​with the preset leakage and pressure stability ranges obtained from the database; the maximum value corresponding to the preset leakage and pressure stability range is not greater than the preset leakage and pressure stability value; if the leakage and pressure stability characteristic value is greater than the maximum value of the preset pressure range, send a high valve opening prompt, and lower the valve opening setting; the preset pressure range maximum value represents the maximum value of the preset leakage and pressure stability range; if the leakage and pressure stability characteristic value is not greater than the maximum value of the preset pressure range, send a low valve opening prompt, and increase the valve opening setting; lowering the valve opening setting means sending a prompt to the preset personnel to reduce the valve opening step by step with the first pressure amplitude obtained from the database. If the obtained pressure balancing valve response time and leakage and pressure stability characteristic values ​​meet the leakage and pressure stability qualification conditions, the execution is stopped. If the valve opening is reduced to the preset minimum valve opening and still does not meet the leakage and pressure Stability qualified conditions, send an alarm prompt; the first pressure amplitude represents the amplitude corresponding to the ratio of the leakage and pressure stability characteristic value to the preset pressure range maximum value; increasing the valve opening setting means sending a prompt to the preset personnel to increase the valve opening step by step with the second pressure amplitude obtained from the database. If the obtained pressure balancing valve response time and leakage and pressure stability characteristic values ​​all meet the leakage and pressure stability qualified conditions, stop execution. If the valve opening is increased to the preset maximum valve opening, it still does not meet the leakage and pressure stability qualified conditions, send an alarm prompt; the second pressure amplitude represents the amplitude corresponding to the ratio of the preset pressure range maximum value and the leakage and pressure stability characteristic value; the leakage and pressure stability qualified conditions indicate that the monitored pressure balancing valve response time is within the preset pressure balancing valve response range, and the leakage and pressure stability characteristic value is greater than the preset leakage and pressure stability value, among which the preset leakage and pressure stability range, the preset pressure range maximum value, the preset maximum valve opening and the preset minimum valve opening are all set in advance by the preset personnel.

[0043] In this embodiment, when the monitored leakage and pressure stability characteristic values ​​are greater than the maximum value of the preset pressure range, this indicates that the resistance to gas passing through the pressure balancing valve is reduced, which may cause the downstream pressure to fall below the preset set value. The gas energy supply equipment may not operate normally, resulting in frequent starts and stops. Gradually reducing the valve opening according to the first pressure amplitude obtained from the database helps gradually increase the resistance to gas passing through the pressure balancing valve, thereby avoiding frequent starts and stops of the gas energy supply equipment due to insufficient pressure. When the monitored leakage and pressure stability characteristic values ​​are not greater than the maximum value of the preset pressure range, this indicates that the resistance to gas passing through the pressure balancing valve is increased, which may cause the preset combustion system of the gas energy supply equipment to be subjected to higher pressure, resulting in increased wear of the gas energy supply equipment. Gradually increasing the valve opening according to the second pressure amplitude obtained from the database helps reduce the resistance to gas passing through the pressure balancing valve, alleviate the workload of various components of the gas energy supply equipment, and reduce the wear rate. Gradually changing the valve opening according to the first pressure amplitude or the second pressure amplitude helps avoid drastic pressure fluctuations caused by larger valve opening adjustments, making the pressure adjustment process more stable and controllable, gradually approaching the preset pressure stable state, and helping to improve the precision and accuracy of pressure adjustment, thereby achieving the effect of improving the operating efficiency of the gas energy supply equipment.

[0044] Furthermore, the gas energy supply equipment operation qualification monitoring includes obtaining the gas energy supply equipment operation qualification quantitative value and operation qualification judgment; the specific process of obtaining the gas energy supply equipment operation qualification quantitative value is as follows: first, the number of start and stop times and the preset number of start and stop times are analyzed to obtain a first operation qualification quantitative value, which is used to reflect the effect of the number of start and stop times on the operation qualification of the gas energy supply equipment. Specifically, the expression of the first operation qualification quantitative value is: E represents the number of the preset operation time period, M represents the total number of preset operation time periods, G 1 (E) represents the first qualified quantitative value of the E-th preset operating time period, QTN(E) represents the number of starts and stops in the E-th preset operating time period, QTN(E) represents the preset number of starts and stops, and the number of times the gas energy supply equipment stops running in the preset operating time period is monitored by an electronic counter as the number of starts and stops. The number of starts and stops and the preset number of starts and stops have no units.

[0045] Next, the maximum temperature difference value of the region and the maximum temperature difference value of the preset region are analyzed to obtain the second qualified operation quantitative value, which is used to reflect the effect of the maximum temperature difference value of the region on the qualified operation of the gas energy supply equipment. Specifically, the expression of the second qualified operation quantitative value is: G 2(E) represents the second qualified quantitative value of the E-th preset operating time period, ΔWCZ(E) represents the regional maximum temperature difference value of the E-th preset operating time period, ΔWCZ(0) represents the preset regional maximum temperature difference value, and the difference between the maximum temperature and the minimum temperature of the position point of the preset device output heat area during the preset operating time period is monitored by the thermal resistance temperature sensor as the regional maximum temperature difference value, and the units of the regional maximum temperature difference value and the preset regional maximum temperature difference value are both in degrees Celsius.

[0046] Then, the gas energy supply equipment startup time and the preset gas energy supply equipment startup time are analyzed to obtain the third operation qualified quantitative value, which is used to reflect the effect of the gas energy supply equipment startup time on the operation qualified status of the gas energy supply equipment. The expression of the third operation qualified quantitative value is: G 3 (E) represents the third qualified operation quantitative value of the Eth preset operation time period, QDT(E) represents the start-up time of the gas energy supply equipment in the Eth preset operation time period, QDT(0) represents the preset gas energy supply equipment start-up time, and the time from the gas energy supply equipment receiving the start-up instruction to reaching the preset operation state during the preset operation time period is monitored by an electronic timer as the start-up time of the gas energy supply equipment, and the units of the gas energy supply equipment start-up time and the preset gas energy supply equipment start-up time are both seconds.

[0047] Finally, the proportion of the regional gas energy supply equipment gas flow and the preset average gas flow is analyzed to obtain the fourth operation qualified quantitative value, which is used to reflect the effect of the regional gas energy supply equipment gas flow on the operation qualified status of the gas energy supply equipment. The expression of the fourth operation qualified quantitative value is: G 4 (E) represents the fourth qualified quantitative value of the Eth preset operating time period, RQLL(E) represents the gas flow of the regional gas energy supply equipment in the Eth preset operating time period, RQLL(0) represents the preset average gas flow, and the gas flow of the preset point of the gas supply pipeline of the gas energy supply equipment in the preset operating time period is monitored by the nozzle flowmeter as the gas flow of the regional gas energy supply equipment. The units of the gas flow of the regional gas energy supply equipment and the preset average gas flow are both cubic meters per hour.

[0048] After coupling the results of weighted analysis of the qualified operation quantitative data with the corresponding qualified operation adjustment value, negative correlation quantification is performed to obtain the qualified operation quantitative value of the gas energy supply equipment, wherein the negative correlation quantification is the inverse operation; the qualified operation quantitative value of the gas energy supply equipment is used to reflect the comprehensive effect of the qualified operation quantitative parameters and the preset qualified operation quantitative parameters on the qualified operation of the gas energy supply equipment.

[0049] Among them, the qualified quantitative value of gas energy supply equipment operation is obtained by the following method:

[0051] Wherein, G(E) represents the leakage and pressure stability characteristic value of the E-th preset operating time period, B1 represents the preset first operating qualified adjustment value, B2 represents the preset second operating qualified adjustment value, B3 represents the preset third operating qualified adjustment value, and B4 represents the preset fourth operating qualified adjustment value.

[0052] The qualified operation quantitative data include the first qualified operation quantitative value, the second qualified operation quantitative value, the third qualified operation quantitative value and the fourth qualified operation quantitative value, and the qualified operation quantitative data all consider the situation greater than 0; the qualified operation quantitative parameters include the number of starts and stops, the maximum temperature difference in the area, the start time of the gas energy supply equipment and the gas flow of the regional gas energy supply equipment; the preset qualified operation quantitative parameters include the preset number of starts and stops, the preset maximum temperature difference in the area, the preset gas energy supply equipment start time and the preset average gas flow; the qualified operation adjustment value includes the preset first qualified operation adjustment value, the preset second qualified operation adjustment value, the preset third qualified operation adjustment value and the preset fourth qualified operation adjustment value, which are used to reflect the influence of the qualified operation quantitative data on the qualified operation quantitative value of the gas energy supply equipment.

[0053] It should be added that the preset operation qualified quantitative parameter is represented by the average value of the operation qualified quantitative parameter in the historical time period; by inputting the real-time operation qualified quantitative data into the corresponding mapping group, the corresponding operation qualified adjustment value can be obtained; the mapping group is obtained from the database and contains a mapping set, which is used to reflect the mapping relationship between the operation qualified quantitative data and the corresponding operation qualified adjustment value, wherein the mapping relationship in the mapping set can be a one-to-one correspondence or a many-to-one relationship; for example, the value range of the operation qualified adjustment value is 0-1.

[0054] In this embodiment, the qualified operation quantitative data is further analyzed to obtain the qualified operation quantitative value of the gas energy supply equipment. A larger qualified operation quantitative data indicates a greater impact of the number of starts and stops on the qualified operation of the gas energy supply equipment, a greater impact of the maximum regional temperature difference on the qualified operation of the gas energy supply equipment, and a greater impact of the gas energy supply equipment startup time on the qualified operation of the gas energy supply equipment, resulting in a smaller qualified operation quantitative value of the gas energy supply equipment. In summary, in this embodiment, the qualified operation quantitative data and the qualified operation quantitative value of the gas energy supply equipment are negatively correlated.

[0055] The qualified operation quantitative parameters monitored in this embodiment do not exist in isolation, but have interrelated characteristics, and correlation analysis is required to describe their joint effects. The more times the start and stop times are, the more thermal cycles will be generated inside the gas energy supply equipment, which may lead to a decrease in the sealing performance between the heat exchange tube and the tube sheet, an increase in local thermal resistance, and an increase in the maximum temperature difference in the region; as the number of starts and stops increases, it may affect the response speed of the preset combustion system, reduce the control accuracy of the gas supply, and make the combustion unstable, thereby prolonging the start-up time; the larger the regional gas flow rate, the more likely it is that the combustion temperature will be too high, the gas energy supply equipment components will be heated unevenly, and it will take longer to stabilize the temperature, thereby prolonging the start-up time; the larger the regional gas flow rate, the more likely it is that the gas energy supply equipment will have combustion anomalies during operation, causing the gas energy supply equipment to shut down, and thus leading to a greater number of starts and stops. By analyzing the comprehensive impact of the parameters, an accurate assessment of the qualified operation of the gas energy supply equipment is achieved, thereby achieving the effect of improving the operating efficiency of the gas energy supply equipment.

[0056] Furthermore, the specific process of operation qualification judgment is as follows: a difference comparison is performed based on the gas energy supply equipment operation qualification quantitative value and the preset energy supply equipment operation qualification value obtained from the database, wherein the preset energy supply equipment operation qualification value is represented by the average value of the gas energy supply equipment operation qualification quantitative value in the historical time period; if the gas energy supply equipment operation qualification quantitative value is greater than the preset energy supply equipment operation qualification value, an operation qualification prompt is sent; if the gas energy supply equipment operation qualification quantitative value is not greater than the preset energy supply equipment operation qualification value, an operation failure prompt is sent, and gas energy supply qualification optimization is performed.

[0057] It should be added that the optimization of gas energy supply qualification includes the determination of the qualified operation range and the adjustment of qualified operation; the specific process of determining the qualified operation range is as follows: comparing the difference between the monitored qualified operation quantitative value of the gas energy supply equipment and the preset qualified operation range of the gas energy supply equipment obtained from the database; the maximum value corresponding to the preset qualified operation range of the gas energy supply equipment is less than the preset qualified operation value of the energy supply equipment; if the qualified operation quantitative value of the gas energy supply equipment is greater than the maximum value of the preset qualified operation range, a first-level qualified operation prompt of the gas energy supply equipment is sent, and the burner injection angle setting is reduced; the maximum value of the preset qualified operation range represents the maximum value of the preset qualified operation range of the gas energy supply equipment; if the qualified operation quantitative value of the gas energy supply equipment is not greater than the maximum value of the preset qualified operation range, a second-level qualified operation prompt of the gas energy supply equipment is sent, and the burner injection angle setting is increased; among them, the preset qualified operation range of the gas energy supply equipment and the maximum value of the preset qualified operation range are set in advance by the preset personnel.

[0058] Specifically, the operation qualification adjustment includes reducing the burner injection angle setting and increasing the burner injection angle setting; reducing the burner injection angle setting means sending a prompt to the preset personnel to gradually reduce the burner injection angle with the qualified operation first amplitude obtained from the data. If the burner injection angle is reduced to the preset minimum injection angle, the gas energy supply equipment operation qualification quantitative value still does not meet the gas energy supply equipment operation qualification condition, and an alarm prompt is sent; the qualified operation first amplitude represents the amplitude corresponding to the ratio of the gas energy supply equipment operation qualification quantitative value to the preset operation qualification range maximum value; increasing the burner injection angle setting means sending a prompt to the preset personnel to gradually increase the burner injection angle with the qualified operation second amplitude obtained from the data. If the burner injection angle is increased to the preset maximum injection angle, the gas energy supply equipment operation qualification quantitative value still does not meet the gas energy supply equipment operation qualification condition, and an alarm prompt is sent, wherein the preset maximum injection angle is set in advance by the preset personnel; the qualified operation second amplitude represents the amplitude corresponding to the ratio of the preset operation qualification range maximum value to the gas energy supply equipment operation qualification quantitative value; the gas energy supply equipment operation qualification condition indicates that the gas energy supply equipment operation qualification quantitative value is greater than the preset energy supply equipment operation qualification value.

[0059] It should be understood that the operation qualification adjustment involved also includes monitoring the operating load of the gas energy supply equipment, as follows; comparing the difference between the monitored gas energy supply equipment operating load and the preset operating load range obtained from the database, wherein the energy load within the preset preset area is monitored by a calorific value analyzer as the gas energy supply equipment operating load; if the gas energy supply equipment operating load is within the preset operating load range, a load qualification prompt is sent; if the gas energy supply equipment operating load is not within the preset operating load range, the operation qualification adjustment is stopped and an alarm prompt is sent, wherein the preset operating load range is set in advance by the preset personnel.

[0060] In this embodiment, by monitoring the qualified quantitative value of the gas energy supply equipment and the preset qualified range of the gas energy supply equipment, when the qualified quantitative value of the gas energy supply equipment is not within the preset qualified range of the gas energy supply equipment, it means that the gas energy supply equipment is in an overloaded or abnormal combustion efficiency state; when it is monitored that the burner injection angle setting is reduced, the burner injection angle is gradually reduced with the qualified operation first amplitude obtained from the data, which helps to increase the mixing time of the gas and air, making the mixing more uniform, thereby improving the combustion efficiency; when it is monitored that the burner injection angle setting is increased, the burner injection angle is gradually increased with the qualified operation second amplitude obtained from the data, which helps to increase the diffusion range of the gas, making the mixing of the gas and air more complete, thereby improving the combustion efficiency, reducing incomplete combustion, ensuring stable combustion, and improving the output of the gas energy supply equipment, thereby achieving the effect of improving the operating efficiency of the gas energy supply equipment.

[0061] In summary, the embodiment of the present application performs gas leakage interference monitoring to determine whether to perform leakage and pressure stability monitoring. If leakage and pressure stability monitoring is performed, it determines whether to perform leakage and pressure stability optimization based on the acquired leakage and pressure stability data. After the leakage and pressure stability monitoring is qualified, the gas energy supply equipment operation qualification monitoring is performed to determine whether to perform gas energy supply qualification optimization, thereby achieving the improvement of the operation qualification of the gas energy supply equipment, and then achieving the improvement of the operation efficiency of the gas energy supply equipment, effectively solving the problem of low control accuracy of the gas energy supply equipment operation due to insufficient pressure balance of the gas energy supply equipment in the prior art.
