Description

Technical Field

[0001] This disclosure relates to the field of coal-fired power generation technology, and in particular to a method, apparatus, electronic equipment and storage medium for controlling the operation of a boiler fan. Background Technology

[0002] Deep regulation technology is currently widely used in coal-fired power generating units. However, due to the low operating load of the units, the load on each boiler fan is also low, resulting in low operating efficiency and high power consumption of the boiler fans. Therefore, how to control the operation of boiler fans under peak load to improve the operating efficiency of each fan and reduce their power consumption is a problem that needs to be solved by the entire power industry.

[0003] In related technologies, the common approach is to add a speed regulating device to the boiler blower to control its operation. For example, by fixing the blower blades (or stationary blades) at a more economical angle, the boiler blower speed is changed to adjust the furnace negative pressure, thereby controlling the operation of the boiler blower and improving its operating efficiency under low load conditions.

[0004] In this way, simply fixing the blades (or stationary blades) of the boiler fan will usually cause jamming of the blades and stationary blades during long-term operation. Moreover, due to the inherent structural limitations of the boiler fan, the operating safety of the boiler fan is relatively poor. Summary of the Invention

[0005] This disclosure aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, the purpose of this disclosure is to provide a method, device, electronic equipment and storage medium for the operation control of a boiler fan, which can effectively improve the accuracy of the operation control of the boiler fan, improve the safety of the boiler fan operation, and thus effectively improve the robustness and applicability of the operation control method of the boiler fan.

[0007] The boiler fan operation control method proposed in the first aspect of this disclosure includes: acquiring multiple initial state parameters of the boiler, wherein the multiple initial state parameters include: initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed; constructing a first objective function relating the initial fan speed, initial total boiler air volume, and initial boiler load; constructing a second objective function relating the initial fan opening degree, initial boiler load, and initial total boiler air volume; determining a target fan speed and a target fan opening degree for the boiler fan when the boiler is in a target operating condition based on the first objective function and the second objective function; and controlling the boiler fan to operate at the target fan speed and target fan opening degree in response to the boiler being in the target operating condition.

[0008] The boiler fan operation control method proposed in the first aspect of this disclosure obtains multiple initial state parameters of the boiler, including initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed. It then constructs a first objective function relating the initial fan speed, initial total boiler air volume, and initial boiler load, and a second objective function relating the initial fan opening degree, initial boiler load, and initial total boiler air volume. Based on the first and second objective functions, it determines the target fan speed and target fan opening degree of the boiler fan when the boiler is in the target operating condition. In response to the boiler being in the target operating condition, it controls the boiler fan to operate at the target fan speed and target fan opening degree. This effectively improves the accuracy of boiler fan operation control, enhances the safety of boiler fan operation, and thus effectively improves the robustness and applicability of the boiler fan operation control method.

[0009] The boiler fan operation control device according to the second aspect embodiment of this disclosure includes: an acquisition module for acquiring multiple initial state parameters of the boiler, wherein the multiple initial state parameters include: initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed; a first construction module for constructing a first objective function between the initial fan speed, the initial total boiler air volume, and the initial boiler load; a second construction module for constructing a second objective function between the initial fan opening degree, the initial boiler load, and the initial total boiler air volume; a determination module for determining the target fan speed and the target fan opening degree of the boiler fan when the boiler is in the target operating condition, based on the first objective function and the second objective function; and a control module for controlling the boiler fan to operate at the target fan speed and the target fan opening degree in response to the boiler being in the target operating condition.

[0010] The boiler fan operation control device proposed in the second aspect of this disclosure acquires multiple initial state parameters of the boiler, including initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed. It then constructs a first objective function relating the initial fan speed, initial total boiler air volume, and initial boiler load, and a second objective function relating the initial fan opening degree, initial boiler load, and initial total boiler air volume. Based on the first and second objective functions, it determines the target fan speed and target fan opening degree of the boiler fan when the boiler is in the target operating condition. In response to the boiler being in the target operating condition, it controls the boiler fan to operate at the target fan speed and target fan opening degree. This effectively improves the accuracy of boiler fan operation control, enhances the safety of boiler fan operation, and further improves the robustness and applicability of the boiler fan operation control method.

[0011] A third aspect of this disclosure provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the boiler fan operation control method as proposed in the first aspect of this disclosure.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] Figure 1 This is a schematic flowchart of a boiler fan operation control method according to an embodiment of this disclosure.

[0027] It should be noted that the execution subject of the boiler fan operation control method in this embodiment is the boiler fan operation control device. This device can be implemented by software and / or hardware. This device can be configured in an electronic device, which may include, but is not limited to, a terminal, a server, etc.

[0028] like Figure 1 As shown, the operation control method of the boiler fan includes:

[0029] S101: Obtain multiple initial state parameters of the boiler, including: initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed.

[0030] Among them, the boiler's state parameters can be used to describe the boiler's operating state. These state parameters can be, for example, the boiler's probability, the boiler's power consumption, etc., without any restrictions.

[0031] In the initial stage of the boiler fan operation control method, the unprocessed boiler state parameters obtained can be referred to as initial state parameters. There are multiple initial state parameters, which may include: initial boiler load P. d Initial total boiler air volume Q d Initial fan opening degree n d Initial fan speed K d No restrictions are placed on this.

[0032] In this embodiment of the disclosure, obtaining multiple initial state parameters of the boiler can be achieved by pre-setting multiple measuring point sensors on the boiler during boiler operation, and collecting the initial boiler load P through these measuring point sensors. d Initial total boiler air volume Q d Initial fan opening degree nd Initial fan speed K d And the initial boiler load P of the boiler obtained above. d Initial total boiler air volume Q d Initial fan opening degree n d Initial fan speed K d These parameters are used together as initial state parameters, and no restrictions are imposed on them.

[0033] In some embodiments, obtaining multiple initial state parameters of the boiler can also be achieved by pre-configuring a corresponding data transmission interface for the boiler fan operation control device, and obtaining the initial boiler load P of the boiler via this data transmission interface. d Initial total boiler air volume Q d Initial fan opening degree n d Initial fan speed K d and the initial boiler load P obtained above. d Initial total boiler air volume Q d Initial fan opening degree n d Initial fan speed K d These parameters are used together as initial state parameters, and no restrictions are imposed on them.

[0034] S102: Construct the first objective function relating the initial fan speed, the initial total boiler air volume, and the initial boiler load.

[0035] The function used to characterize the relationship between the initial fan speed, the initial total boiler air volume, and the initial boiler load can be called the first objective function.

[0036] In some embodiments, constructing a first objective function relating the initial fan speed, the initial total boiler air volume, and the initial boiler load may involve determining the correlation between the initial fan speed, the initial total boiler air volume, and the initial boiler load, and constructing the first objective function relating the initial fan speed, the initial total boiler air volume, and the initial boiler load based on this correlation.

[0037] In other embodiments, the first objective function between the initial fan speed, the initial total boiler air volume, and the initial boiler load can be constructed. Alternatively, it can be generated by customizing the first objective function between the initial fan speed, the initial total boiler air volume, and the initial boiler load using Matrix Laboratory (MATLAB). There are no restrictions on this.

[0038] Optionally, in some embodiments, constructing the first objective function relating the initial fan speed, the initial total boiler air volume, and the initial boiler load can be achieved by constructing a first function relating the initial fan speed and the initial boiler load based on a first correlation between them, and a second function relating the initial fan speed and the initial total boiler air volume based on a second correlation between them. The first and second functions are then used together as the first objective function. This allows for the construction of a first function that clearly represents the first correlation between the initial fan speed and the initial boiler load, and a second function that clearly represents the second correlation between them. Therefore, using both the first and second functions together as the first objective function effectively improves the reference value of the first objective function.

[0039] There can be a correlation between the initial fan speed and the initial boiler load, which can be called the first correlation.

[0040] The function used to characterize the first correlation between the initial fan speed and the initial boiler load can be called the first function.

[0041] There can be a correlation between the initial fan speed and the initial total boiler air volume, which can be called the second correlation.

[0042] The function used to characterize the second correlation between the initial fan speed and the initial total boiler air volume can be called the second function.

[0043] In other words, in this embodiment of the disclosure, a first function relating the initial fan speed and the initial boiler load can be constructed based on the first correlation between the initial fan speed and the initial boiler load (the function curve of the first function can be as follows). Figure 2 As shown, Figure 2 This is a schematic diagram of a first function curve proposed in an embodiment of this disclosure. The first function can be expressed as:

[0044] n d =ap d +c;

[0045] Where, n d It is the initial fan speed, p d is the initial boiler load, and a and c are the parameters of the first function.

[0046] In other words, in this embodiment of the disclosure, a second function relating the initial fan speed and the initial total boiler air volume can be constructed based on the second correlation between the initial fan speed and the initial total boiler air volume (the function curve of the second function can be as follows). Figure 3 As shown, Figure 3 This is a schematic diagram of a second function curve proposed in an embodiment of this disclosure. The second function can be expressed as:

[0047] n d =bQ d +e;

[0048] Where, n d It is the initial fan speed, Q d is the initial total boiler air volume, and b and e are the parameters of the second function.

[0049] S103: Construct a second objective function relating the initial fan opening, initial boiler load, and initial total boiler air volume.

[0050] The function used to characterize the relationship between the initial fan opening, the initial boiler load, and the initial total boiler air volume can be called the second objective function.

[0051] In some embodiments, constructing a second objective function relating the initial fan opening, the initial boiler load, and the initial total boiler air volume can be achieved by determining the correlation between the initial fan opening, the initial boiler load, and the initial total boiler air volume, and constructing the second objective function relating the initial fan opening, the initial boiler load, and the initial total boiler air volume based on this correlation.

[0052] In other embodiments, a second objective function is constructed between the initial fan opening, the initial boiler load, and the initial total boiler air volume. Alternatively, the second objective function can be custom-generated using Matrix Laboratory (MATLAB), without any limitations.

[0053] Optionally, in some embodiments, constructing the second objective function relating the initial fan opening, the initial boiler load, and the initial total boiler air volume can be achieved by constructing a third function relating the initial fan opening and the initial boiler load based on a third correlation, and a fourth function relating the initial fan opening and the initial total boiler air volume based on a fourth correlation. The third and fourth functions are then used together as the second objective function. This allows for the construction of a third function that clearly represents the third correlation between the initial fan opening and the initial boiler load, and a fourth function that clearly represents the fourth correlation between the initial fan opening and the initial total boiler air volume. Therefore, using both the third and fourth functions together as the second objective function effectively improves the reference value of the second objective function.

[0054] There can be a correlation between the initial fan opening and the initial boiler load, which can be called the third correlation.

[0055] The function used to characterize the third correlation between the initial fan opening and the initial boiler load can be called the third function.

[0056] Among them, there can be a corresponding correlation between the initial fan opening degree and the initial total boiler air volume, which can be called the fourth correlation relationship.

[0057] The function used to characterize the fourth correlation between the initial fan opening and the initial total boiler air volume can be called the fourth function.

[0058] In other words, in this embodiment of the disclosure, a third function relating the initial fan opening and the initial boiler load can be constructed based on the third correlation between the initial fan opening and the initial boiler load (the function curve of the third function can be as follows). Figure 4 As shown, Figure 4 This is a schematic diagram of a third function curve proposed in an embodiment of this disclosure. The third function can be expressed as:

[0059] k d =fp d +g;

[0060] Where, k d It is the initial fan opening, p d is the initial boiler load, and f and g are the parameters of the third function.

[0061] In other words, in this embodiment of the disclosure, a fourth function can be constructed based on the fourth correlation between the initial fan opening and the initial total boiler air volume (the function curve of the fourth function can be as follows). Figure 5 As shown, Figure 5 This is a schematic diagram of the fourth function curve proposed in an embodiment of this disclosure. The fourth function can be expressed as:

[0062] k d =hQ d +i;

[0063] Where, k d It is the initial fan opening, Q d is the initial total boiler air volume, and h and i are the parameters of the fourth function.

[0064] S104: Based on the first objective function and the second objective function, determine the target fan speed and target fan opening of the boiler fan when the boiler is in the target operating condition.

[0065] Specifically, the target operating conditions of the boiler can be, for example, boiler start-up and shutdown conditions, boiler feeding conditions, etc. Figure 2 , Figure 3 , Figure 4 , Figure 5 The TEST1, TEST2, ... TESTN conditions shown are not restricted.

[0066] Among them, when the boiler is in the target operating condition, the optimal fan speed of the boiler fan can be called the target fan speed, and the optimal fan opening of the boiler fan can be called the target fan opening, without any restrictions.

[0067] In other words, the boiler fan operation control method described in the embodiments of this disclosure can support the control and adjustment of the boiler fan speed and fan opening, so that the boiler fan runs at the target fan opening and target fan speed, without limitation.

[0068] In this embodiment of the disclosure, determining the target fan speed and target fan opening of the boiler fan when the boiler is in the target operating condition, based on the first objective function and the second objective function, can be achieved by obtaining the reference boiler load, reference total boiler air volume, reference fan opening, and reference fan speed of the boiler under the target operating condition when the boiler is operating in a relatively optimal state. The parameters of the first and second objective functions are then revised based on these parameters, and the revised first and second objective functions are solved to determine the target fan speed and target fan opening of the boiler fan when the boiler is in the target operating condition.

[0069] Alternatively, the target fan speed and target fan opening of the boiler fan can be determined based on the first objective function and the second objective function when the boiler is in the target operating condition. Alternatively, the function curves of the first objective function and the second objective function can be fitted, and the target fan speed and target fan opening of the boiler fan when the boiler is in the target operating condition can be determined by combining the fitted function curves. There are no restrictions on this.

[0070] S105: In response to the boiler being in the target operating condition, control the boiler fan to operate at the target fan speed and the target fan opening.

[0071] In this embodiment of the disclosure, after determining the target fan speed and target fan opening degree of the boiler fan when the boiler is in the target operating condition according to the first objective function and the second objective function, the boiler fan can be controlled to operate at the target fan speed and target fan opening degree in response to the boiler being in the target operating condition.

[0072] In other words, in this embodiment of the present disclosure, a corresponding monitoring device may be pre-set for the boiler, and the boiler operation process may be continuously monitored through the monitoring device. When the boiler is detected to be in the target operating condition, the boiler fan may be controlled to run at the target fan speed and the target fan opening, without any restrictions.

[0073] Optionally, in some embodiments, in response to the boiler being in the target operating condition, controlling the boiler fan to operate at the target fan speed and target fan opening can be achieved by determining the current fan speed and current fan opening of the boiler fan in response to the boiler being in the target operating condition, adjusting the current fan speed to the target fan speed, and adjusting the current fan opening to the target fan opening. This accurately achieves the control of the boiler fan to operate at the target fan speed and target fan opening, effectively ensuring the operating control effect of the boiler fan.

[0074] In the context of boiler operation, the current speed of the boiler fan and the current opening degree of the boiler fan can be referred to as the current fan speed and the current fan opening degree.

[0075] In other words, in this embodiment of the present disclosure, the boiler fan operation control device may be pre-configured with a corresponding data transmission interface, and the current fan speed and current fan opening of the boiler fan may be obtained through the data transmission interface. The current fan speed may be adjusted to the target fan speed, and the current fan opening may be adjusted to the target fan opening, so as to control the boiler fan to run at the target fan speed and target fan opening. There are no restrictions on this.

[0076] In this embodiment, multiple initial state parameters of the boiler are obtained, including initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed. A first objective function is constructed between the initial fan speed, initial total boiler air volume, and initial boiler load, and a second objective function is constructed between the initial fan opening degree, initial boiler load, and initial total boiler air volume. Based on the first and second objective functions, the target fan speed and target fan opening degree of the boiler fan when the boiler is in the target operating condition are determined. In response to the boiler being in the target operating condition, the boiler fan is controlled to operate at the target fan speed and target fan opening degree. This effectively improves the accuracy of boiler fan operation control, enhances the safety of boiler fan operation, and thus effectively improves the robustness and applicability of the boiler fan operation control method.

[0077] Figure 6 This is a schematic flowchart of a boiler fan operation control method according to another embodiment of this disclosure.

[0078] like Figure 6 As shown, the operation control method of the boiler fan includes:

[0079] S601: Obtain multiple initial state parameters of the boiler, including: initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed.

[0080] S602: Construct the first objective function relating the initial fan speed, the initial total boiler air volume, and the initial boiler load.

[0081] S603: Construct a second objective function relating the initial fan opening, initial boiler load, and initial total boiler air volume.

[0082] For a detailed description of S601-S603, please refer to the above embodiments, which will not be repeated here.

[0083] S604: Fit the first objective function and the second objective function to obtain the third objective function between the initial fan opening and the initial fan speed.

[0084] The function used to characterize the data correlation between the initial fan opening and the initial fan speed can be called the third objective function.

[0085] In this embodiment of the disclosure, after constructing a first objective function between the initial fan speed, the initial total boiler air volume, and the initial boiler load, and a second objective function between the initial fan opening degree, the initial boiler load, and the initial total boiler air volume, the first objective function and the second objective function can be fitted to obtain a third objective function between the initial fan opening degree and the initial fan speed.

[0086] In this embodiment of the disclosure, the above can be achieved by modifying the... Figure 2 , Figure 3 , Figure 4 , Figure 5 The analysis of the curve of the function shown involves fitting the first and second objective functions to obtain a third objective function relating the initial fan opening and the initial fan speed (the curve of the third objective function can be shown as follows). Figure 7 As shown, Figure 7 This is a schematic diagram of the third objective function curve proposed in an embodiment of this disclosure. Then, it can be combined with... Figure 7 The third objective function curve shown determines the speed and opening degree of the boiler fan to be processed when the boiler is in the target operating condition. For details, please refer to the following embodiments.

[0087] S605: Based on the third objective function, determine the speed and opening degree of the boiler fan to be processed when the boiler is in the target operating condition.

[0088] In this embodiment of the present disclosure, after fitting the first objective function and the second objective function to obtain the third objective function between the initial fan opening and the initial fan speed, the fan speed of the boiler fan when the boiler is in the target operating condition can be determined and the fan speed is taken as the fan speed to be processed, and the fan opening of the boiler fan when the boiler is in the target operating condition can be determined as the fan opening to be processed.

[0089] For example, determining the speed and opening degree of the boiler fan under target operating conditions can be achieved, for instance, by determining the boiler under target operating conditions. Figure 7 When the target operating condition (TEST1) is shown, the fan speed corresponding to the data point of TEST1 in the third objective function curve is determined, and this fan speed is used as the fan speed to be processed. The fan opening corresponding to the data point of TEST1 in the third objective function curve is also determined, and this fan speed is used as the fan opening to be processed. Then, based on the fan speed and fan opening to be processed, the subsequent boiler fan operation control method can be executed. For details, please refer to the following embodiments.

[0090] S606: Determine the target fan speed based on the fan speed to be processed.

[0091] In this embodiment of the invention, after determining the speed of the fan to be processed, the target fan speed can be determined to be 90%-110% of the speed of the fan to be processed. That is to say, the speed of the fan to be processed can be any fan speed value within the range of 90%-110% of the speed of the fan to be processed. Thus, a certain speed margin can be given to the boiler fan speed, so that when the boiler fan enters the resonance speed range, a rapid override increase / decrease method can be used to avoid resonance, thereby keeping the boiler fan away from the resonance range and ensuring the safety of boiler fan operation.

[0092] S607: Determine the target fan opening based on the fan opening of the fan to be processed.

[0093] In this embodiment of the present disclosure, after determining the opening degree of the fan to be processed, the target fan opening degree can be determined to be 60%-90% of the fan opening degree to be processed. That is to say, the fan opening degree to be processed can be any fan opening degree value within the range of 60%-90% of the fan opening degree to be processed. Thus, it can effectively ensure that the opening degree of the moving blade of the boiler fan can be in the high-efficiency range of the boiler fan, thereby effectively improving the operating efficiency of the boiler fan and effectively improving the economic efficiency of the boiler fan operation.

[0094] S608: In response to the boiler being in the target operating condition, control the boiler fan to operate at the target fan speed and the target fan opening.

[0095] For a detailed description of S608, please refer to the above embodiments, which will not be repeated here.

[0096] In this embodiment, multiple initial state parameters of the boiler are acquired, including initial boiler load, initial total boiler air volume, initial fan opening degree, and initial fan speed. A first objective function is then constructed relating the initial fan speed, initial total boiler air volume, and initial boiler load. A second objective function is also constructed relating these parameters. The first and second objective functions are then fitted to obtain a third objective function relating the initial fan opening degree and initial fan speed. Based on the third objective function, the required fan speed and opening degree are determined when the boiler is in the target operating condition. Finally, the target fan speed is determined based on the required fan speed. Thus, a certain target fan speed can be assigned to the boiler fan. The system allows for a margin of safety in the boiler fan's speed. This allows for rapid overdrive adjustments when the fan enters the resonance speed range, preventing resonance and ensuring safe operation. Furthermore, by determining the target fan opening based on the fan opening to be addressed, the system effectively ensures the fan's blade opening remains within its high-efficiency range, thus improving operating efficiency and economy. Finally, in response to the boiler operating at the target condition, the system controls the fan to run at the target speed and opening, thereby enhancing the accuracy and safety of the control, and ultimately improving the robustness and applicability of the control method.
