Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The core of the invention is to provide an energy-saving optimization method of the low-temperature economizer, which can enable the low-temperature economizer to have the optimal energy-saving. Another core of the present invention is to provide a low-temperature economizer energy-saving optimizing device, apparatus and computer-readable storage medium, which all have the above-mentioned beneficial effects.
Referring to fig. 1, a flowchart of a low-temperature economizer energy-saving optimization method according to an embodiment of the invention is shown.
The invention provides an energy-saving energy optimization method of a low-temperature economizer, which comprises the following steps.
S1: the method comprises the steps of obtaining a pre-disturbance preset operation parameter when the current low-temperature economizer operates under the current working condition, and calculating first energy saving of the current low-temperature economizer according to the pre-disturbance preset operation parameter.
As is known, the low-temperature economizer has different structures, mounting modes and mounting positions, and the energy conservation amounts corresponding to the low-temperature economizer are different, so that the current low-temperature economizer is a low-temperature economizer with determined structures, mounting modes and mounting positions.
It should be noted that, the energy saving amount of the current low-temperature economizer refers to the energy consumption saved for the whole unit of the thermodynamic system after the current low-temperature economizer is applied, and a specific calculation formula of the energy saving amount of the current low-temperature economizer can be referred to the prior art, and is not repeated herein.
It is understood that the preset operation parameters refer to parameters required for calculating the energy saving amount of the current low-temperature economizer, and are related to the operation parameters of the thermodynamic system unit, and can be determined by a person skilled in the art according to a specific calculation formula of the energy saving amount of the current low-temperature economizer.
In view of the convenience of description, the preset operation parameter corresponding to the thermodynamic system unit before the disturbance is applied to the preset variable of the current low-temperature economizer is referred to as a pre-disturbance preset operation parameter, and the energy saving amount of the current low-temperature economizer calculated by using the pre-disturbance preset operation parameter is referred to as a first energy saving amount.
It should be noted that, the preset operation parameters before disturbance may be obtained in real time from a system such as SIS (safety instrument system) or DCS (distributed control system).
S2: disturbance is applied to preset variables of the current low-temperature economizer.
It can be understood that the operation value of the preset variable of the current low-temperature economizer, for example, the flow of the current low-temperature economizer, the water inlet temperature value of the current low-temperature economizer and the like have a critical influence on the first energy saving of the current low-temperature economizer, so that in order to enable the current low-temperature economizer to have the optimal energy saving amount, the operation value of the preset variable of the current low-temperature economizer is changed by applying disturbance to the preset variable of the current low-temperature economizer, when the operation value of the preset variable of the current low-temperature economizer is changed, the first energy saving of the current low-temperature economizer is also changed, and whether the operation value of the preset variable of the current low-temperature economizer is the optimal operation value can be judged according to the change of the energy saving amounts of the current low-temperature economizer before and after the disturbance, wherein the preset variable can be any operation parameter of the current low-temperature economizer.
It should be noted that, the disturbance applied to the preset variable by the present invention may be a positive step disturbance, a negative step disturbance, or other disturbance forms.
S3: and acquiring a post-disturbance preset operation parameter of the current low-temperature economizer when the current low-temperature economizer operates under the current working condition, and calculating the second energy-saving amount of the current low-temperature economizer according to the post-disturbance preset operation parameter.
It should be noted that, the preset operation parameters after disturbance refer to preset operation parameters corresponding to the thermodynamic system unit after disturbance is applied to preset variables of the current low-temperature economizer; the second energy saving amount is the energy saving amount of the current low-temperature economizer calculated by utilizing the preset operation parameters after disturbance.
Similarly, the preset operation parameters after disturbance can be obtained in real time from systems such as SIS (safety instrument system) or DCS (distributed control system).
S4: and judging whether the result of the preset relation between the first energy saving amount and the second energy saving amount meets a preset range or not.
S5: if not, taking the preset operation parameters after disturbance as the preset operation parameters before disturbance, taking the second energy saving amount as the first energy saving amount, and repeatedly executing S2 to S4 until the result of the preset relation satisfies the preset range.
That is, after the first energy saving amount and the second energy saving amount of the current low-temperature economizer are calculated, whether the operation value of the preset variable of the current low-temperature economizer is the optimal operation value can be judged according to the relation between the first energy saving amount and the second energy saving amount.
Specifically, whether the operation value of the preset variable of the current low-temperature economizer is the optimal operation value is judged by judging whether the result of the preset relation between the first energy saving amount and the second energy saving amount meets the preset range or not.
If the result of the preset relation between the first energy saving amount and the second energy saving amount meets the preset range, the operation value of the preset variable of the current low-temperature economizer before disturbance is applied is indicated to meet the requirement, and the operation value is the optimal operation parameter. If the result of the preset relation between the first energy saving amount and the second energy saving amount does not meet the preset range, the operation value of the preset variable of the current low-temperature economizer before disturbance is indicated to be a non-optimal parameter, at this time, the preset operation parameter after disturbance is taken as a new preset operation parameter before disturbance, the second energy saving amount is taken as the first energy saving amount, and then the steps S2 to S4 are repeatedly executed until the result of the preset relation between the first energy saving amount and the second energy saving amount meets the preset range.
That is, the present invention aims at energy saving by continuously applying disturbance to the preset variable of the current low-temperature economizer to continuously optimize the operation value of the preset variable of the current low-temperature economizer until the energy saving amount of the current low-temperature economizer reaches the optimum.
Therefore, the energy-saving energy optimization method of the low-temperature economizer provided by the invention can monitor the energy-saving effect of the current low-temperature economizer in real time by calculating the energy-saving energy of the current low-temperature economizer under the current working condition; and the energy saving amount of the current low-temperature economizer is taken as a target, whether the operation value of the preset variable of the current low-temperature economizer is the optimal operation parameter is judged according to the result of a relational expression between the energy saving amounts of the current low-temperature economizer before and after the disturbance is applied by applying the disturbance to the preset variable of the current low-temperature economizer, and the operation value of the preset variable of the current low-temperature economizer is continuously optimized by continuously applying the disturbance to the preset variable of the current low-temperature economizer, so that the current low-temperature economizer works under the optimal operation parameter, and the current low-temperature economizer has the optimal energy saving amount.
It should be noted that, the energy saving amount of the current low-temperature economizer corresponds to the working condition of the thermodynamic system unit, and under different working conditions, the thermodynamic system unit has different pre-disturbance preset operation parameter values and post-disturbance preset operation parameter values, so that the corresponding values of the first energy saving amount and the second energy saving amount of the current low-temperature economizer under different working conditions are different. Therefore, by changing the working conditions of the thermodynamic system unit, the running values of the preset variables of the current low-temperature economizer under different working conditions can be optimized according to the method, so that the current low-temperature economizer has the best energy saving capacity under different working conditions.
In addition, the specific form of the preset relation of the first energy saving and the second energy saving is not limited in the present invention, for example, the preset relation of the first energy saving and the second energy saving may be a comparison relation, a difference relation, a proportional relation or other functional relation, and those skilled in the art may select according to actual needs.
Based on the above embodiment, step S4: judging whether the result of the preset relation between the first energy saving amount and the second energy saving amount meets a preset range or not, comprising:
and judging whether the absolute value of the difference value between the second energy saving amount and the first energy saving amount is smaller than or equal to a set value.
That is, the present embodiment determines whether the operation value of the preset variable of the current low-temperature economizer is the optimal operation parameter by making a difference between the second energy saving amount and the first energy saving amount and by determining whether the absolute value of the difference between the two is less than or equal to the set value.
It should be noted that, in this embodiment, the specific value of the set value is not limited, and those skilled in the art may select according to actual situations.
It can be understood that when the absolute value of the difference between the second energy saving amount and the first energy saving amount is smaller than or equal to the set value, the change amount between the first energy saving amount and the second energy saving amount is small, which indicates that the current low-temperature economizer works under the optimal operation parameters, and at this time, the operation values of the preset variables of the current low-temperature economizer before and after the disturbance can be considered as the optimal operation values.
When the absolute value of the difference between the second energy saving amount and the first energy saving amount is larger than a set value, the change amount between the first energy saving amount and the second energy saving amount is larger, at the moment, the operation value of the preset variable of the current low-temperature economizer before disturbance is proved to be a non-optimal operation value, the operation value of the preset variable of the current low-temperature economizer needs to be adjusted, at the moment, the operation value of the preset variable of the current low-temperature economizer after disturbance is taken as a new operation value, and whether the operation value of the preset variable of the current low-temperature economizer is the optimal operation value is judged by further applying disturbance to the preset variable of the current low-temperature economizer.
Specifically, on the basis of the above embodiment, after taking the post-disturbance preset operation parameter as the pre-disturbance preset operation parameter and taking the second energy saving amount as the first energy saving amount, and before repeatedly executing S2 to S4, the method further includes:
it is determined whether the second energy saving amount is greater than the first energy saving amount.
If yes, repeating S2 to S4, wherein, when repeating S2, applying a disturbance to a preset variable of the current low-temperature economizer, including:
and (3) applying external positive step disturbance to preset variables of the current low-temperature economizer.
Further, on the basis of the above embodiment, after determining whether the second energy saving amount is larger than the first energy saving amount, it further includes:
if not, repeating S2 to S4, wherein, when repeating S2, applying a disturbance to a preset variable of the current low-temperature economizer, including:
and applying an external negative step disturbance to a preset variable of the current low-temperature economizer.
That is, when the second energy saving amount is greater than the first energy saving amount, an external forward step disturbance is applied to a preset variable of the current low-temperature economizer; and when the second energy saving energy is smaller than the first energy saving energy, applying external negative step disturbance to a preset variable of the current low-temperature economizer.
Referring to fig. 2, a flowchart of a method for optimizing energy saving of a low-temperature economizer according to a second embodiment of the present invention is shown.
In order to make the current low-temperature economizer always in the optimal operation state, after judging whether the result of the preset relation between the first energy saving amount and the second energy saving amount meets the preset range or not, the method further comprises the following steps of:
s6: if so, the first operation value of the preset variable before disturbance is applied or the second operation value of the preset variable after disturbance is applied is used as the optimal operation parameter of the current low-temperature economizer, so that the current low-temperature economizer operates according to the first operation value or the second operation value.
That is, the operation value of the preset variable before the disturbance is applied is referred to as a first operation value, and the operation value of the preset variable after the disturbance is applied is referred to as a second operation value, and when the result of the preset relation between the first energy saving amount and the second energy saving amount satisfies the preset range, it is explained that the operation values of the preset variable of the current low-temperature economizer before and after the disturbance are both optimal operation parameters, and at this time, the current low-temperature economizer can be operated according to the first operation value, and also can be operated according to the second operation value.
Referring to fig. 3, a flowchart of a method for optimizing energy saving of a low-temperature economizer according to a third embodiment of the present invention is shown.

S72: it is determined whether the third energy saving amount is greater than the first energy saving amount.
S73: if yes, outputting a conclusion that the structure of the second low-temperature economizer is better than that of the current low-temperature economizer.
That is, the embodiment judges the advantages and disadvantages of the energy conservation amounts of the current low-temperature economizer and the second low-temperature economizer by comparing the energy conservation amounts of the current low-temperature economizer and the second low-temperature economizer under the same working condition, so as to find the low-temperature economizer with a better structure, so that the low-temperature economizer in the whole unit of the thermodynamic system is structurally modified in the later period, and the purpose of maximizing the energy conservation amount of the low-temperature economizer is achieved.
