First embodiment
Referring to fig. 1, a system architecture for a boiler operation load parameter adjusting method or a boiler operation load parameter adjusting device according to the present invention is provided in this embodiment.
As shown in fig. 1, the system structure 100 includes a boiler group (also referred to as a boiler plant group) 120 and an optimization algorithm module 110, wherein the boiler group 120 includes a plurality of boilers (also referred to as boiler plants) 121, 122, 123, and each of the boilers 121, 122, 123 includes at least one electronic device 131, 132, 133 for controlling the boilers 121, 122, 123. The optimizing algorithm module 110 calculates data based on optimal configuration for the boiler group 120 and outputs a target parameter, and the boiler group 120 responds to the target parameter to achieve optimal configuration, such as load-optimized operation.
In particular, the electronic devices 131, 132, 133 may include software, hardware, or a combination of both. When the electronic devices 131, 132, and 133 are hardware, they may include a computer, a microcontroller, a storage medium, a custom chip, and the like, such as an industrial personal computer, or a controller based on a single chip or an application specific integrated circuit. When the electronic devices 131, 132, 133 are software, they may include application programs or computer programs installed in the above hardware, for example, a computer program implementing the optimization algorithm module 110. Of course, the electronic devices 131, 132, 133 may also be a combination of the above-mentioned software and hardware, such as a microcomputer system, which includes various computer programs for controlling and regulating the boiler and hardware devices supporting the operation of the computer programs.

In an implementation, the optimization algorithm module 110 can solve algorithms for various data-driven modeling, such as a modeling method based solely on evolutionary algorithms or linear programming. Since the optimization algorithm module 110 can be a conventional one, it is not described herein.
Second embodiment
Fig. 2 is a flowchart illustrating an implementation of a method for adjusting an operating load parameter of a boiler according to an embodiment of the present invention. In this embodiment, the main body of the boiler operation load parameter adjustment method may be any electronic device, such as the electronic devices 131, 132, and 133 shown in fig. 1.
Referring to fig. 2, the method for adjusting the operating load parameter of the boiler specifically includes the following steps S210 to S260:
s210: obtaining a first target parameter output by an optimization algorithm, wherein the first target parameter comprises a load related parameter obtained by aiming at each boiler in a boiler group to realize global optimal load operation under the optimization algorithm.
Specifically, the optimization algorithm is the prior art, and the first target parameter output by the optimization algorithm is a parameter for realizing global optimal load operation, which is obtained by performing a modeling algorithm solution based on data generated by operation of a boiler group or external data as a drive. Wherein, due to the fact that at least one or more boilers are included in one boiler group, the first target parameter includes an operation target parameter for each boiler in the boiler group, so as to realize the adjustment of the boiler load.
For example, in the case of fig. 1, the boilers 121, 122, 123 shown in fig. 1 are included in a boiler group, that is, a boiler group consisting of three boilers, wherein the load-related parameters obtained by implementing the global optimal load operation under the optimization algorithm for each boiler 121, 122, 123 in the boiler group are W1, W2, W3, and then the first target parameter can be represented as Wi, i e [1, 2, 3 ]. With this adjustment of the first target parameter Wi, each boiler 121, 122, 123 in the boiler group can be made to operate at the most economical or advantageous load under data based on closed-loop feedback. Specifically, the load-related parameter may specifically be an outlet flue gas amount, a fuel supply amount, or a load value of the boiler, that is, the load-related parameter may be any relevant parameter for realizing load adjustment of the boiler, and the load-related parameter may correspond to a specific load value of the boiler. In actual operation, the boiler is operated at too high or too low a load, neither being the most economical nor the most advantageous.
S220: and presetting a load upper and lower limit extreme value for the boilers in the boiler group.
Specifically, the upper and lower limit load values are an upper limit value and a lower limit value of an output load preset for each boiler in the boiler group, and are used for judging whether a load parameter output by the optimization algorithm exceeds the upper and lower limit load values of the boiler.
S230: setting a first load related parameter exceeding a preset upper and lower limit value of a corresponding boiler in the load related parameters as a new upper and lower limit value of the load of the boiler; and calculating the difference value between the first load related parameter in the boiler group and the preset upper and lower limit load extreme values of the corresponding boiler, accumulating the difference value, and calculating the total load difference of the boiler group.
Specifically, although the first target parameters output by the existing optimization algorithm implement the optimal operation parameter scheme of the boiler group under the global condition, the load-related parameters of some boilers in the first target parameters cannot be matched with the actual operation conditions of the boilers. For example, referring again to FIG. 1, assuming that the load-related parameter W1 for the boiler 101 in the first target parameter Wi would cause the load of the boiler operation to exceed the highest practical limit, the instability of the boiler would be caused, and a new problem would be caused.
In this embodiment, the upper and lower limit values of the preset load of each boiler in the boiler group are used to overcome the problem that the operation of the boiler exceeds the actual load limit due to the load-related parameters output by the optimization algorithm and specific to the boiler.
In some embodiments, the upper and lower load limits comprise an upper load limit and a lower load limit for each boiler in the group of boilers. Similarly, for example, the boiler group includes the boilers 121, 122, 123, and the upper and lower limit load values of the boilers 121, 122, 123 are X1, Y1, X2, Y2, X3, and Y3, respectively. The upper and lower limit load limit values include an upper limit load value and a lower limit load value, that is, the upper limit load value of the boiler 121 is X1, and the lower limit load value is Y1. Similarly, the upper limit of the load of the boiler 122 is X2, and the lower limit of the load is Y2; the upper limit load of the boiler 123 is X3, and the lower limit load is Y3. In this embodiment, the load upper limit value and the load lower limit value preset for each boiler are used to limit the load-related parameters of the first target parameters for the boiler, which easily causes the problem that the boiler exceeds the load limit operation.
In particular, the limitation of the load-related parameter for each boiler in this step will be described more clearly by way of specific examples.
For an example, please refer to fig. 3, which is a flowchart of an implementation of step S230 shown in fig. 2 in an embodiment. Referring to fig. 3, step S230 specifically includes steps S310 to S322:
s310: and aiming at the load related parameters of the boiler, comparing whether the load related parameters are greater than the preset load upper limit value of the corresponding boiler.
Specifically, the load upper limit value specifically preset for the boiler may not be the same parameter as the load-related parameter for the boiler in the first target parameter. For example, the upper load limit may be a specific power value, and the load-related parameter is the steam outlet amount, and the comparison between the two values requires conversion. For example, the upper limit load value may be converted into a parameter corresponding to the load-related parameter, for example, the power value corresponding to the upper limit load value may be converted into the corresponding steam outlet amount, or the steam outlet amount may be converted into the corresponding load value.
It should be noted that the conversion of the above different parameters is conventional or prior art for those skilled in the art, and therefore, will not be described herein.
S321: if yes, the load related parameter is a first load related parameter, the first load related parameter is set as a new upper limit value of the load of the boiler, the difference between the first load related parameter and the upper limit value of the load is calculated, and the total load difference of the boiler group is accumulated and calculated.
Specifically, the first load-related parameter is a classification of the load-related parameters, specifically, those load-related parameters that exceed the upper and lower limit values of the boiler load among the load-related parameters, that is, the first load-related parameter is not limited to the load-related parameter of a certain boiler. As the first load-related parameter exceeding the upper load limit value, it is necessary to limit it to exceed the upper load limit value, i.e., to make the first load-related parameter equal to the upper load limit value. For example, assume that the load-related parameter W2 of the boiler 122 exceeds the upper load limit X2, and the load-related parameter W3 of the boiler 123 exceeds the upper load limit X3; then, W2 and W3 are the first load-related parameters, and there are W2 ═ X2 and W3 ═ X3.
In addition, the load-related parameters exceeding the load limit are limited to the extreme values of the upper and lower load limits. The total load difference caused by the limitation is also recorded, because the first target parameter is based on the optimal parameter solution realized globally by the boiler group, so that the first target parameter corresponds to a balanced system for the whole boiler group, and when a certain load-related parameter is limited, specific change of the parameter is necessarily caused, and the change can destroy the balance of the system, and therefore, the total load difference caused by the limitation is recorded.
Specifically, since the number of the first load-related parameters may be more than one, when the plurality of load-related parameters are limited due to exceeding the upper and lower limit load values, the load differences between the plurality of different load-related parameters and the upper and lower limit load values may be accumulated to obtain a total difference value, i.e., a total load difference. For example, also taking the example that the boiler group includes the boilers 121, 122, 123, when the load-related parameter W2 of the boiler 122 exceeds the load upper limit value X2, assuming that the total load difference is Z, in this case, Z is W2-X2; when the load-related parameter W3 of the boiler 123 exceeds the load upper limit value X3, the total load difference is (W2-X2) + (W3-X3).
The total load difference Z is W2-X2, which is not inconsistent with W2 being X2 in the above example. Since the first load-related parameter is another name for the load-related parameter, its specific value is not limited. For example, when the load-related parameter W2 is greater than X2, the load-related parameter W2 is the first load-related parameter, and assuming that the load-related parameter W2 is 13 and the load upper limit value X2 is 10, that time, the first load-related parameter W2 is 10, the total load difference Z is initially 0, and the total load difference Z is W2-X2 is 13-10-3.
S322: if not, comparing whether the load related parameters are smaller than the load lower limit value of the corresponding boiler or not.
Similarly, when the load-related parameter does not exceed the upper limit of the load, it is also necessary to determine whether the load-related parameter exceeds the lower limit of the load of the boiler.
For a second example, please refer to fig. 4, which is a flowchart illustrating the implementation of step S322 shown in fig. 3 in an embodiment.
As shown in fig. 4, the step S322 may specifically include the steps of:
s410: if yes, the load related parameter is a first load related parameter, the first load related parameter is set as a new load lower limit value of the boiler, the difference between the first load related parameter and the load lower limit value is calculated, and the total load difference of the boiler group is accumulated and calculated.
Also, the present step S410 is different from the step S321 only in the load limit. Specifically, for example, the boiler group includes the boilers 121, 122, and 123, and assuming that the load-related parameter W2 of the boiler 122 exceeds the lower load limit value Y2, that is, W2 < Y2, at this time, W2 is Y2, and Z is (W2-Y2). Specifically, in the boiler group, the boiler 123 exceeds the upper limit of the load of the boiler, i.e., W3 < X3, and the total load difference Z is (W2-Y2) + (W3-X3).
S420: and if not, marking the load related parameter as a second load related parameter.
Specifically, the second load-related parameter and the first load-related parameter are both load-related parameters under different conditions.
It should be noted that, in practical applications, the determination of whether the load-related parameter exceeds the upper and lower limit values of the boiler load is not limited to the steps in the above examples. For example, in the specific implementation, it may be determined whether the load-related parameter exceeds the lower limit of the load of the boiler, and then determined whether the load-related parameter exceeds the upper limit of the load. The method and the device do not limit the judgment sequence of the upper limit value and the lower limit value of the load.
S240: and redistributing the total load difference to a second load-related parameter which does not exceed the upper and lower limit values of the preset load of the corresponding boiler in the load-related parameters in proportion.
Specifically, more than one way of distributing the total difference in load may be used, for example, an even distribution may be used. However, considering that the distribution of the total difference also needs to be guaranteed not to exceed the extreme value of the boiler, the distribution can be realized by utilizing a preset distribution coefficient.
Example three, as shown in fig. 5, is a flowchart of the implementation of step S240 in fig. 2 in an embodiment. As shown in fig. 5, the step S240 specifically includes the steps of:
s510: and determining the distribution proportion of the boiler corresponding to the second load related parameter based on the preset distribution coefficient aiming at each boiler in the boiler group.
Specifically, the setting of the distribution coefficients is not limited, and it is only required to ensure that the sum of the distribution coefficients of all the boilers in the boiler group is equal to 1.
S520: and determining the total load difference share distributed by the boiler according to the distribution proportion.
S530: calculating the sum of the second load-related parameter and the corresponding total difference share of the load.
Specifically, the total load difference share allocated to each second load-related parameter that does not exceed the upper and lower limit of load is equal to the allocation ratio of the total load difference to the second load-related parameter.
The determination of the allocation ratio in step S510 can be shown in fig. 6, which is a flowchart of the implementation of step S510 in fig. 5 in an embodiment. As shown in fig. 6, the step S510 specifically includes:
s610: and determining the distribution proportion of the boiler corresponding to the second load related parameter.
Specifically, for example, in combination with the boilers 121, 122, 123 shown in fig. 1, it is assumed that the distribution coefficients of the boilers 121, 122, 123 are a1, a2, a3, and the load-related parameters of the boilers 121, 122, 123 are W1, W2, W3, where the load-related parameters for the boilers 122 and 123 exceed the upper and lower limit load extremes, that is, the total load difference is distributed in the second load-related parameters W2 and W3.
S620: and determining the sum of the distribution coefficients of all the second load-related parameters corresponding to the boilers.
Specifically, in conjunction with the above assumptions, the sum of the partition coefficients is (a2+ a 3).
S630: and calculating the ratio of the distribution coefficient of the boiler corresponding to the current second load related parameter to the sum of the distribution coefficients, and taking the ratio as the distribution proportion of the total load difference.
Specifically, the distribution ratio of the second load related parameter corresponding to the boiler 122 is as follows: a2/(a2+ a3), and in the same way, the distribution proportion of the second load-related parameter corresponding to the boiler 123 is: a3/(a2+ a 3).
From the above, the total differential load share allocated to the boiler 122 is: a2/(a2+ a3) × Z, the total differential load share distributed to the boiler 123 is: a3/(a2+ a3) Z.
In addition, after the total load difference is distributed, the actual human load related parameters, such as the boiler 122, may exist, i.e., W2 ═ W2+ (a2/(a2+ a2)) × Z. At this time, after the load total difference distribution is performed, the second load-related parameter is increased, so that there is a possibility that the load upper and lower limit values are exceeded.
Specifically, in some embodiments, after the step S530, the method may further include the steps of: judging whether the sum of each second load related parameter and the corresponding load total difference share exceeds a preset upper and lower load limit extreme value of the corresponding boiler or not; if yes, initializing the total load difference to be zero, and returning to the step S230; if not, the process proceeds to step S250. In this embodiment, it is equivalent to perform the re-load upper and lower limit value judgment on the second load-related parameter, and if the second load-related parameter exceeds the load upper and lower limit value, the total load difference is accumulated again and the second load-related parameter is redistributed, so as to implement the operation of the boiler within the composite limit without damaging the optimal operation adjustment of the first target parameter output by the optimization algorithm on the boiler group.
S250: and updating the first target parameter based on the first load related parameter and the second load related parameter to obtain a second target parameter.
Specifically, after the load upper and lower limit extreme values are judged according to the load related parameters of all the boilers in the boiler group, the total load difference exceeding the load upper and lower limit extreme values is redistributed, so as to realize the balance of the system. Accordingly, the load-related parameter in the original first target parameter is also changed, and the changed load-related parameter becomes the final target parameter, i.e., the second target parameter.
S260: and outputting the second target parameter.
By the method provided by the embodiment, the optimization algorithm can be directly applied to the on-site boiler group without changing the existing optimization algorithm, and the optimal load operation target parameter output by the optimization algorithm can be directly responded under the condition of ensuring that the boiler operates within the load limit.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
