Description

Technical Field

[0001] This disclosure relates to the field of carbon emission accounting and measurement technology, specifically to a method, apparatus, equipment, storage medium, and product for determining carbon emissions. Background Technology

[0002] Reducing carbon emissions is one of the important means to mitigate global warming caused by the greenhouse effect. As a traditional industry, underground coal mining involves important carbon emission accounting and measurement. With breakthroughs in advanced technologies, mechanization in underground coal mining has been widely applied, and it mainly uses purchased electricity as its energy supply. Therefore, in order to quantify the carbon emissions generated by the underground coal mining process, it is necessary to accurately calculate the use of purchased electricity in the mining process.

[0003] On the one hand, some power branches lack electricity meters, or the electricity reports are incomplete, statistically incorrect, or unusable. On the other hand, there are errors in measuring or calculating electricity consumption using meters on branch circuits. For example, the electricity consumption measured or calculated on the main circuit is often not equal to the sum of the electricity consumption measured or calculated on all branch circuits in the entire plant. This results in the electricity consumption measured or calculated on the branch circuits not being equal to the actual electricity consumption of the branch circuits.

[0066] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of these messages or information. It is understood that before using the technical solutions disclosed in the embodiments of this disclosure, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in this disclosure in an appropriate manner in accordance with relevant laws and regulations, and user authorization should be obtained.

[0067] First, the application scenario of this disclosure will be explained. Taking the power supply system of XXX coal mine as an example, the 35kV substation at the ventilation shaft site serves as the mine's main substation. The 35kV voltage is transformed to 10kV and connected to the 10kV main distribution cabinet in a specific form. Let the average active power metering of this main distribution cabinet be P (kW). It is then distributed to various area or functional distribution cabinets via the 10kV distribution cabinet, such as the main shaft drive room distribution cabinet, ventilation fan distribution cabinet, underground central substation distribution cabinet, industrial plant substation distribution cabinet, underground central frequency converter system distribution cabinet, and air compressor station distribution room distribution cabinet. The average active power metering of the above distribution cabinets are P1 (kW), P2 (kW), P3 (kW), P4 (kW), P5 (kW), and P6 (kW), respectively. In practical scenarios, each area or functional distribution cabinet is connected to other electrical equipment or sub-distribution cabinets. For example, the main shaft drive room distribution cabinet is connected to equipment 11, equipment 12, and so on up to equipment 1n. The underground central substation distribution cabinet is not only connected to equipment 31, equipment 32, and so on up to equipment 3n, but also to a sub-distribution cabinet 31, whose average hourly active power is measured as P. 31(kW) When calculating carbon emissions from the use of purchased electricity across the entire plant, it is necessary to calculate the hourly active power consumption P of the purchased electricity. When it is necessary to separately calculate carbon emissions from each power-consuming branch, process stage, or individual large electrical equipment due to the use of purchased electricity, some power-consuming branches can use the hourly average active power consumption P from their respective distribution cabinets. i (i = 1, 2, 3, 4, 5, 6), some process steps are distributed across different power branches, and some individual large electrical equipment lines do not have average active power metering, or only average current intensity I. ij (A) (i = 1, 2, 3, ..., m; j = 1, 2, 3, ..., n) data can be used. Therefore, the actual electricity consumption of each power-consuming branch, process link, or individual large-scale electrical equipment requires a certain standardized and reasonable calculation method to ensure that the accurate carbon emissions of these branches or equipment can be obtained. The following describes this disclosure in conjunction with specific embodiments.

[0068] Figure 1 This is a flowchart illustrating a method for determining carbon emissions according to an exemplary embodiment. Figure 1 As shown in the embodiments of this disclosure, a method for determining carbon emissions is provided, which may include the following steps:

[0069] In step S10, the metering power of the electrical equipment in each branch circuit of the main circuit is obtained, wherein the power used by the main circuit is external power.

[0070] In this step, the metered power of the electrical equipment in each branch circuit of the main circuit is obtained, wherein the power used by the main circuit is external power. For example, the external power can be purchased power, which may include conventional power, green power, and / or energy storage power.

[0071] In step S20, the percentage of the metered power of the electrical equipment in the branch circuit in the sum of the metered power of all electrical equipment in the branch circuit is obtained.

[0072] In this step, the percentage of the metered power of the electrical equipment in this branch circuit in the sum of the metered power of the electrical equipment in all branch circuits is obtained.

[0073] In step S30, the actual power consumption of the electrical equipment in the branch circuit is obtained based on the proportion and the metered power consumption of the total distribution cabinet of the trunk circuit.

[0074] In this step, the actual power consumption of the equipment in the branch circuit is obtained based on the proportion and the metered power consumption of the total distribution cabinet of the trunk circuit. For example, the actual power consumption of the equipment in the branch circuit can be obtained by multiplying the proportion and the metered power consumption of the total distribution cabinet of the trunk circuit.

[0075] Generally, assuming the total hourly purchased electricity consumption of the entire plant is P1 (kWh), theoretically, P1 should equal the sum of the purchased electricity metering values ​​of each area or functional distribution cabinet, P2. However, in reality, due to line losses and metering errors, P1 ≠ P2. If the average hourly active power metering of each area or functional distribution cabinet is used directly, the metering of purchased electricity consumption in each branch will be inaccurate, indirectly leading to inaccurate carbon emission metering due to the use of purchased electricity in each branch. Therefore, the average hourly active power metering of the entire plant can be redistributed to each branch according to the proportion of purchased electricity consumption in each branch. This way, the actual power consumption of the equipment in the branch circuit can be accurately obtained, and thus the actual carbon emissions of the equipment in the branch circuit can be obtained.

[0076] In step S40, the carbon emission factor of the external power is obtained.

[0077] In this step, the carbon emission factor of external electricity is obtained. For example, this carbon emission factor can be a mixed carbon emission factor that includes various electricity sources.

[0078] In step S50, the actual carbon emissions of the electrical equipment in the branch circuit are determined based on the actual power consumption and the carbon emission factor.

[0079] In this step, the actual carbon emissions of the electrical equipment in the branch circuit are determined based on the actual power consumption and the carbon emission factor. For example, the actual carbon emissions of the electrical equipment in the branch circuit can be determined by multiplying the actual power consumption of the branch circuit by the carbon emission factor.

[0080] In summary, this disclosure provides a method for determining carbon emissions. The method includes: obtaining the metered power of electrical equipment in each branch circuit of a main circuit, wherein the power used by the main circuit is external power; obtaining the proportion of the metered power of the electrical equipment in the branch circuit to the sum of the metered power of all electrical equipment in the branch circuits; obtaining the actual power consumption of the electrical equipment in the branch circuits based on the proportion and the metered power consumption of the main circuit's total distribution cabinet; obtaining the carbon emission factor of the external power; and determining the actual carbon emissions of the electrical equipment in the branch circuits based on the actual power consumption and the carbon emission factor.
