Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of energy management, and particularly relates to a general IEMS energy unit unit consumption analysis method for industrial production. BACKGROUND

[0002] In 2022, the total energy consumption in China reached 54.1 billion tons of standard coal, an increase of 2.9% over the previous year. The energy situation in China is still severe, and the realization of the double carbon goal not only depends on the development of new energy, but also requires good overall planning of traditional energy. According to data from the National Bureau of Statistics, industrial energy consumption accounts for about 60% of the total energy consumption of society, making industry the main field of energy consumption and carbon dioxide emissions in China. Doing a good job in energy saving and emission reduction in the industrial field is one of the important means for China to achieve the carbon peak and carbon neutral goals.

[0003] Integrated Energy Management System (IEMS) is a system that integrates regional electricity, natural gas, coal, oil, heat and other multiple energies, realizes coordinated planning, collaborative management, optimized operation, interactive response and complementary mutual aid between multiple heterogeneous energy subsystems. IEMS plays an important role in energy fine management, especially in the industrial field, which plays an important role in improving the energy consumption management level of industrial production, mastering the real-time operation of energy, improving energy utilization efficiency, reducing energy costs, and reducing carbon emissions.

[0004] In industrial enterprises, an important indicator for evaluating energy management level is unit consumption, i.e. the amount of energy consumed per unit of product. Unit consumption is generally calculated for specific production units, which can be the entire factory, a workshop, a work section, or a device, collectively referred to as energy-consuming units in this patent. For a certain energy-consuming unit, the same type of product, under the same production output, if the energy consumption is too high, it means that there is a problem of energy leakage or unreasonable production arrangement. Unit consumption analysis is one of the important means to realize fine management of industrial production energy consumption and improve production management level. However, due to the high complexity of industrial production, energy consumption is closely related to the production process. For unit consumption analysis, energy-consuming units vary in type, energy input is diverse, and production products are complex and numerous. The lack of a universal model leads to a large amount of development of unit consumption analysis functions and high project investment costs. Most current unit consumption analysis is rarely involved in IEMS project construction, and the few IEMSs that exist still need to be customized for different projects and different scenarios, which are difficult to apply to other projects. The developed IEMS ends with the end of the project, causing a certain degree of waste of resources. SUMMARY

[0005] The present application aims to provide a general IEMS energy unit specific consumption analysis method for industrial production to solve the problems in the background.

[0006] To achieve the above object, the present application provides the following technical solution: a general IEMS energy unit specific consumption analysis method for industrial production, comprising the following steps:

[0007] S1, establishing an energy-using unit entity relationship E-R conceptual model;

[0008] S2, establishing an energy-using unit energy consumption statistical accounting model;

[0009] S3, establishing an energy-using unit specific consumption accounting model;

[0010] S4, establishing an energy-using unit analysis configuration and business display function model.

[0011] Preferably, in the S1, when the IEMS performs specific consumption analysis, the entities of the energy-using unit entity relationship E-R conceptual model include energy units, products, energy, and measuring meters; the core entity in the entities is the energy unit, the production object of the core entity is the product, and the consumption object of the core entity is the energy; the energy measuring instrument is the measuring instrument; the core attributes of the energy unit are the affiliated organization, the energy unit type, the energy unit code, and the energy unit name; the core attributes of the energy are the energy type and the energy consumption; the core attributes of the product are the product type, the product code, the product name, and the product yield; the core attributes of the measuring meter are the meter type, the meter code, the meter name, the meter address, and the statistical amount; the energy-using unit in the energy-using unit entity relationship E-R conceptual model is a factory, a workshop, a work section, or a device; and the energy data in the IEMS can be calculated by the measuring meter.

[0012] Preferably, the energy-using unit energy consumption statistical accounting model comprises an energy-using unit energy consumption physical quantity accounting model and an energy-using unit energy consumption standard coal accounting model.

[0013] Preferably, the energy-using physical quantity in the energy-using unit energy consumption physical quantity accounting model is the sum of the actual consumption of the same type of energy; when the input energy of the energy-using unit is only one type of energy, the measuring meter is of the same type, the statistical amount of the meter is directly used to calculate the energy physical consumption, the energy-using unit physical quantity accounting is related to the statistical amount calculated by the meter, the allocation coefficient, and the inclusion or exclusion in a certain time period, and the energy-using unit physical quantity calculation model is shown in formula (1).

[0014]

[0015] In formula (1), u represents a unit of energy consumption, t represents a time period of energy consumption, m represents a meter included in the unit of energy consumption u, N u represents the total number of meters included in the unit of energy consumption u, E u,t represents the actual amount of energy consumption of the unit of energy consumption u in the time period t, E m,t represents the amount of energy consumption of the meter m in the time period t, a m represents the allocation coefficient of the meter m for accounting for the unit of energy consumption t, and the coefficient is 1 by default. When the meter is shared, the allocation is shared. [-]: the logic of whether the meter m is subtracted in the accounting of the unit of energy consumption u. This item can be omitted by default. When omitted, it means accumulation.

[0016] For a unit of energy consumption containing multiple types of energy, the actual amount of energy consumption of each type of energy in the unit is calculated using formula (1). At this time, m represents only the meter of the specific calculated energy type in the unit of energy consumption u.

[0017] Preferably, in the standard coal calculation model of the unit of energy consumption, the standard coal equivalent is a unified unit of measurement for comprehensive calculation of energy, including converting the energy contained in various different energies into the amount of standard fuel according to the equivalent calorific value. When the unit of energy consumption contains meters of multiple energy types, the unit of energy consumption accounts for the sum of multiple energy types. Since the units of the actual amounts of each energy are inconsistent, standard coal conversion is used for measurement during accounting. Different energy conversion coefficients are different, and the coefficients are sunk to meter calculation. The conversion coefficients of meters measuring the same type of energy are the same. The standard coal calculation model of the unit of energy consumption is shown in formula (2):

[0018]

[0019] In formula (2), u, t, m, N u , E m,t , a m have the same meaning as formula (1); Sce u,t represents the standard coal amount of the unit of energy consumption u in the time period t, p m,e represents the conversion coefficient of the energy type e to which the meter m belongs. In actual development, according to the given entity relationship model E-R of the unit of energy consumption, the corresponding configuration function is developed, and then according to the related calculation model of the unit of energy consumption given by S2, a general energy consumption statistical function module of the unit of energy consumption is generated.

[0020] Preferably, in S3, on the basis of the energy consumption model of the unit of energy consumption, a unit consumption accounting model of the unit of energy consumption is further established. The unit consumption accounting model of the energy unit is established in two ways: including a single energy unit consumption accounting model and a comprehensive energy unit consumption accounting model.

[0021] In the single energy unit consumption accounting model: the input energy of the energy-using unit is one kind of energy, or there are multiple energy inputs, and the single energy consumption analysis model is shown in formula (3):

[0022]

[0023] In formula (3), U u,e represents the consumption of a certain energy in the energy-using unit u to produce a unit product, E u,t represents the real amount of a certain single energy consumed by the energy-using unit u in the time period t, which is the calculation result of the energy consumption real amount accounting model formula (1) of the energy-using unit, N u,p represents the total number of products produced by the energy-using unit u, O i,t represents the output of the i-th product in the time period t, δ i is the product conversion coefficient.

[0024] In the comprehensive energy unit consumption accounting model:

[0025] The input energy of the energy-using unit is multiple energy, and the comprehensive unit consumption analysis of all energy of the energy-using unit is needed, and the comprehensive energy unit consumption analysis model is shown in formula (4):

[0026]

[0027] In formula (4), U u,sce represents the comprehensive consumption of multiple energy in the energy-using unit u to produce a unit product, Sce u,t represents the standard coal consumption of multiple energy consumed by the energy-using unit u in the time period t, which is the calculation result of the energy consumption standard coal accounting model formula (2) of the energy-using unit, and other parameters are the same as formula (3).

[0028] Preferably, in S4, the system function prototype design, the IEMS general energy-using unit consumption analysis function prototype includes configuration function model and business display function model;

The product yield configuration is used to realize the yield input of products in a time period, and the main information of the product yield configuration includes: product type, product code, start time, end time, and yield.

[0030] In the business display function model, two kinds of general business display function models are included, which are: an energy unit statistical function model and a unit consumption analysis function model.

[0036] Fig. 2 Figure 2 is a system block diagram of the present application. DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0038] Embodiment 1

[0039] Referring to Figs. 1-2 , the present application provides a technical solution: a general IEMS energy unit specific consumption analysis method for industrial production, a modeling process as shown in Fig. 1 , mainly including: establishing an energy consumption analysis entity connection conceptual model, establishing an energy unit energy consumption statistical accounting model, establishing an energy unit specific consumption accounting model, and establishing an energy unit analysis function model. The energy unit energy consumption accounting model includes an energy unit physical quantity accounting model and an energy unit standard coal accounting model. The energy unit specific consumption accounting model includes a single energy specific consumption accounting model and a comprehensive energy specific consumption accounting model. The energy unit analysis function model includes a configuration function model and a business display function model. Generally, the latter model is established on the basis of the former model. For the business display function model, the energy unit statistical function mainly depends on the energy unit energy consumption statistical accounting model, and the energy unit specific consumption analysis function depends on both the energy unit energy consumption statistical accounting model and the energy unit specific consumption accounting model.

[0040] S1. Establish an energy unit entity connection conceptual model:

[0041] The general energy unit specific consumption analysis entity connection E-R conceptual model given by the present application is as shown in Fig. 2 , when IEMS performs specific consumption analysis, the entities mainly involve energy units, products, energy, and measurement meters. The core entity is the energy unit, the production object is the product, the consumption object is the energy, and the energy measuring tool is the measuring instrument. The core attributes of the energy unit are the affiliated organization, the energy unit type, the energy unit code, and the energy unit name. The core attributes of the energy are the energy type and the energy consumption. The core attributes of the product are the product type, the product code, the product name, and the product yield. The core attributes of the measurement meter are the meter type, the meter code, the meter name, the meter address, and the statistical quantity.

[0042] For the energy unit in the above model, it can be a factory, a workshop, a work section or a device, and the core factors for energy unit consumption analysis can be classified as energy input and product output. According to the model analysis, the core data for consumption calculation is energy consumption data and production yield data, and the energy data can be obtained by measuring the meter in IEMS.

[0043] S2. Establishing an energy consumption statistical accounting model of the energy unit:

[0044] In the energy unit consumption analysis, the energy consumption is the input. The energy input types of different energy units may be different. For the similarities and differences of energy types, the present application proposes two types of energy consumption accounting models of energy units: energy consumption physical quantity accounting model of energy unit and energy consumption standard coal accounting model of energy unit.

[0045] (1) Energy consumption physical quantity accounting model of energy unit

[0046] The energy physical quantity refers to the actual consumption sum of the same type of energy. When the input energy of the energy unit is only one type of energy, the measuring meter is of the same type, and the statistical amount of the meter can be directly used to calculate the energy physical consumption. The physical quantity accounting of the energy unit is related to the statistical amount calculated by the meter measurement in a certain time period, the allocation coefficient, and the inclusion or exclusion. The present application researches and gives the energy unit physical quantity calculation model as shown in formula (1):

[0047]

[0048] In formula (1), u represents the energy unit, t represents the energy use time period, m represents the measuring meter contained in the energy unit u, N u represents the total number of measuring meters contained in the energy unit u, E u,t represents the energy physical quantity of the energy unit u in the time period t, E m,t represents the energy consumption of the measuring meter m in the time period t, a m represents the allocation coefficient of the measuring meter m for accounting the energy unit t, and the default coefficient is 1. When the measuring meter is public, public allocation needs to be performed. [-] represents the logic of whether the measuring meter m is subtracted in accounting the energy unit u, and this item can be omitted by default. When omitted, it means accumulation.

[0049] For example, scenario 1: a lathe production workshop as a energy unit carries out energy physical quantity accounting, its main energy consumption is electricity, there are three lines of electricity, respectively, lighting electricity, air conditioning electricity and power electricity. Among the three electricity lines, the air conditioning electricity is installed with an electric meter M1 for independent measurement of the workshop. The lighting electricity is installed with an electric meter M2 for shared electricity, which shares a line with other workshops, and the public sharing ratio is 0.4. The power electricity is installed with two electric meters, one electric meter M3 measures the electricity of all production equipment located in the workshop, and the other electric meter M4 specially measures a special production equipment located in the workshop, which does not belong to the production workshop and is borrowed by other workshops.

[0050] Suppose, on December 19, 2023, the daily electricity consumption of each electric meter is: M1: 312kwh, M2: 128kwh, M3: 5860kwh, M4: 424kwh. Then the total physical electricity consumption of the lathe production workshop on December 19, 2023 is calculated according to formula (1) as follows:

[0051] E 车床车间,2023-12-19 = 312 + 128 * 0.4 + 5860 - 424 = 5799.2 (kwh)

[0052] When calculating the public sharing ratio of lighting electricity is 0.4, it needs to be multiplied by 0.4 based on the electricity consumption. For M4, since it does not belong to the aluminum alloy workshop, it needs to be subtracted.

[0053] It should be noted that for a energy unit containing multiple types of energy, formula (1) can also be used to calculate the energy physical quantity of a specific type of energy in the energy unit. At this time, m represents only the measurement meter of all the energy types in the energy unit u that belong to the specific calculation.

[0054] (2) Energy unit standard coal consumption accounting model

[0055] When the energy unit contains multiple types of energy meters, i.e. the energy unit needs to account for the sum of multiple types of energy, since the physical quantity units of each type of energy are different, they cannot be directly calculated, and need to be measured by standard coal conversion. Different energy conversion coefficients are different, and the coefficient can be sunk to the meter calculation. The meter consumption of the same type of energy has the same conversion coefficient. The standard coal calculation model of the energy unit is shown in formula (2).

[0056]

[0057] In formula (2), u, t, m, N u , E m,t , a m have the same meaning as formula (1). Sce u,trepresents the standard coal consumption of the energy unit u in the t time period, p m,e represents the conversion factor of the energy type e of the measuring meter m.

[0058] For example, scenario 2: energy unit statistics accounting is carried out for a bogie section, and the input energy of the energy unit is electricity, natural gas and compressed air. The installed measuring meters, conversion factors and consumption on December 19, 2023 of each type of energy are shown in the following table.

[0059] Table 1

[0060]

[0061]

[0062] Then, the standard coal consumption of the bogie section on December 19, 2023 is calculated according to formula (2) as follows:

[0063] Sce 转向架车间,2023-12-19

[0064] = 532*0.1229 + 403*0.1229 + 396*0.1229 + 4008*0.1229 + 436*0.1229 + 0.6*128*0.1229 + 102*1.2143 + 2293.4*0.01

[0065] = 65.3828 + 49.5287 + 48.6684 + 492.5832 + 53.5844 + 9.43872 + 123.8586 + 22.934

[0066] = 865.97882 (kgce)

[0067] Finally, the standard coal consumption of the energy unit bogie section is calculated to be 865.97882 kgce.

[0068] S3. Establishing energy unit unit consumption accounting model

[0069] On the basis of the energy consumption model of the energy unit, the energy unit unit consumption accounting model is further established. Similarly, the unit consumption accounting model of the energy unit can be established in two ways: single energy unit consumption accounting model and comprehensive energy unit consumption accounting model.

[0070] (1) Single energy unit consumption accounting model

[0071] For the scenario where the input energy of the energy unit is one kind of energy, or there are multiple energy inputs and only one kind of energy is analyzed for unit consumption analysis, the single energy unit consumption analysis model is given by formula (3).

[0072]

[0073] In formula (3), U u,e represents the amount of a certain energy consumed by the energy-using unit u to produce a unit product, E u,t represents the amount of a certain single energy consumed by the energy-using unit u in the time period t, which is the calculation result of the energy-using unit energy consumption physical quantity accounting model formula (1), N u,p represents the total sum of product types produced by the energy-using unit u, O i,t represents the output of the i-th product produced in the time period t, δ i is the product conversion coefficient.

[0074] In the above model, it should be noted that the product conversion coefficient δ i is mainly due to the fact that different types of products may differ in size, weight, etc., resulting in differences in product consumption time and energy consumption. Therefore, for the analysis of unit consumption of the same energy-using unit with different types of products, the product conversion coefficient is added, and a certain type of product is taken as the standard, and other types of products are converted.

[0075] For example, scenario 3: taking the lathe production workshop in scenario 1 as the energy consumption background, the energy-using unit produced 3 types of products on December 19, 2023, and the output and conversion coefficient of each product are shown in Table 2.

[0076] Table 2

[0077]

[0078] Then, the unit product energy consumption of the lathe workshop can be calculated as follows:

[0079]

[0080] The unit consumption calculation result of the lathe workshop energy-using unit is 88.1337 kwh / table.

[0081] (2) Comprehensive energy unit consumption accounting model

[0082] For the scenario where the input energy of the energy-using unit is multiple energies, comprehensive unit consumption analysis of all energies of the energy-using unit is needed, and the comprehensive energy unit consumption analysis model of the present application is shown in formula (4).

[0083]

[0084] In formula (4), U u,sce represents the comprehensive amount of multiple energies consumed by the energy-using unit u to produce a unit product, Sce u,tThe standard coal consumption of the energy unit u in the time period t is a calculation result of the energy consumption standard coal accounting model formula (2), and other parameters are the same as formula (3).

[0085] It should be noted that for the single energy input scene, the above model can also be used for standard coal consumption analysis, at this time, all the measuring meters belong to the same energy type, and there is only one standard coal conversion coefficient.

[0086] For example, scene 4: taking the comprehensive energy consumption of a bogie section in scene 2 as the energy consumption background, taking the product output data in scene 3 as the background, according to formula (4), the relevant data can be calculated as follows:

[0087]

[0088] The comprehensive unit consumption of the bogie section energy unit is 13.16 kgce per bogie.

[0089] S4, establishing an energy unit analysis configuration and business display function model

[0090] For the purpose of generalization, the system function prototype is designed, and the present application provides an IEMS generalization energy unit consumption analysis function prototype, mainly including a configuration function model and a business display function model.

The energy unit configuration mainly realizes the configuration of the basic information of the energy unit, and the main information includes: unit code, unit name, unit belonging to the organization, unit input energy type, unit measuring meter information, etc. The product information configuration mainly realizes the configuration of the related information of the enterprise production product, and the main information includes: product type, product id, product code, product name, conversion coefficient, belonging to the energy unit, unit. The product output configuration mainly realizes the input of the product output in a certain time period, and the main information includes: product type, product code, start time, end time, and output.

[0093] (2) Business display function model:

[0094] The present application provides two general business display function models: an energy unit statistical function model and a consumption analysis function model.

[0095] Energy unit statistical function prototype:

[0096] According to the energy unit consumption accounting model provided in S2, a general standard energy unit statistical function prototype can be designed. The input of the function prototype mainly includes: energy unit, physical consumption / standard coal consumption, time granularity, time range, query type, chart type. The output of the function prototype mainly includes: daily evaluation, monthly evaluation, annual evaluation, energy consumption trend display based on granularity, peak and valley proportion analysis (only for electricity), and correlation equipment energy consumption proportion.

[0097] It should be noted that the energy unit statistical function model provided by the present application can not only be applied to unit analysis of workshops, sections and equipment of industrial enterprises, but also be applicable to energy consumption statistics of buildings, medical treatment and other industries.

[0098] Energy unit consumption analysis function prototype:

The input of the function prototype mainly includes: time granularity, time range, unit type, energy unit, query type, product output. The output mainly includes unit product consumption trend display chart and list display. The list includes date, energy consumption, output, and unit consumption.

For different projects or different production environments, the specific project site personalized energy unit analysis requirements can be met through configuration, thereby reducing the construction investment of IEMS.
