Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the proposal of the targets of carbon peak reaching and carbon neutralization, the power grid enterprise plays a role in leading an industrial chain and actively responds to national call and action schemes. As the supply chain upstream of the power grid enterprise, the green transformation also becomes one of the social responsibility and the important task of the transformer enterprise. Development of carbon emission accounting becomes a basic premise of accurately mastering the variation trend of carbon emission of transformer enterprises, effectively promoting development of various carbon emission reduction works and promoting green transformation of enterprises, and is also an important support for actively responding to transformation of green supply chains of power grid enterprises. Therefore, transformer enterprises push the supply chain to reduce carbon under the double-carbon background, and the full-chain business emission needs to be checked more finely, so that a method for identifying the carbon emission of the enterprises more effectively and accurately is created.
Under the background of 'double carbon', the state provides a deepened electric power system reform, constructs a novel carbon power system taking new energy as a main body, and determines the target directions of green energy transformation and excitation decarburization in the electric power industry. With the increase of power demand and the continuous deepening of the policy of energy conservation and consumption reduction, the nation encourages the green sustainable development of transformer enterprises and supports energy-saving, low-noise and intelligent distribution transformer products.
In order to support green transformation of enterprises, carbon checking is developed to promote the carbon reduction of transformer enterprises, and carbon emission accounting can help the transformer enterprises to find the emission and develop the carbon reduction more accurately and efficiently. The method is very important for creating a set of transformer enterprise production logistics carbon emission accounting model.
The embodiment of the application provides a logistics carbon emission accounting method for transformer production, which is used for helping transformer enterprises to find out emission amount and more accurately and efficiently carry out carbon reduction work.
The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for accounting for carbon emission of a transformer production stream according to an embodiment of the present application. As shown in fig. 1, the method mainly comprises the following steps:
In an embodiment of the present application, the carbon emission accounting boundary of the transformer includes: obtaining raw materials and energy sources of transformer enterprises, producing and assembling transformers and transporting transformer finished products.
That is, the carbon emission accounting of the transformer products is mainly performed in three links of transformer enterprise raw material and energy acquisition, transformer production and assembly and transformer finished product transportation.
It should be noted that carbon emissions of the transformer product may be generated in other links in the full life cycle, for example, in the using link of the transformer and the waste recycling link of the transformer, considerable carbon emissions may be generated, and especially in the using link of the transformer, the generated carbon emissions may account for more than half of the total carbon emissions in the full life cycle of the transformer product. However, in the present application, statistics and accounting are performed only for the transformer product production logistics link, that is, the carbon emission generated by the transformer enterprise raw material and energy acquisition, the transformer production and assembly, and the transformer finished product transportation link determined by the transformer carbon emission accounting boundary.
Further, the energy consumption of the transformer in the production and assembly stages includes: direct energy consumption and indirect energy consumption; the numerical value obtaining process of the direct energy consumption and the indirect energy consumption comprises the following steps:
measuring the energy consumption value of a single transformer, and multiplying the energy consumption value by the number of the transformers to obtain direct energy consumption;
and receiving the reported public energy consumption data of the factory area, the office area and the storage area, and evaluating to obtain indirect energy consumption.
And 102, generating a carbon emission accounting list of the transformer.
In the embodiment of the present application, a carbon emission accounting list of the transformer is generated through three links of obtaining raw materials and energy sources of a transformer enterprise, producing and assembling the transformer and transporting a finished transformer product, which are determined in the carbon emission accounting boundary of the transformer determined in step 101, and the accounting list is shown in the following table,

In one embodiment of the present application, the process of evaluating the indirect energy consumption is: the direct energy consumption and transportation energy consumption of transformer production are reduced by the total energy consumption of enterprises, and public energy consumption is obtained; and performing linear regression analysis on the public energy consumption and the number of the transformers to obtain the indirect energy consumption of transformer production.
It should be noted that, regarding the evaluation of indirect energy consumption, since the public energy consumption of the enterprise includes a part which is not highly related to the production of the transformer, it is difficult to accurately distinguish and measure in reality, and therefore, an evaluation method of linear regression is designed. Firstly, the total energy consumption of an enterprise is reduced by direct production energy consumption and transportation energy consumption, and then the public energy consumption is obtained. And then performing linear regression analysis on the common energy consumption and the transformer production data in the observation period to obtain indirect production energy consumption which is highly linearly related to the transformer production and partial energy consumption which is not highly related to the transformer production.
Therefore, after accurate evaluation, the carbon emission accounting model of the transformer is optimized as follows:
S＝[Rn+n*Pd++Ln+Tn]*F
wherein S is the total carbon emission of the transformer, n is the number of the transformer, and RnEnergy consumption, P, for transformer enterprises in raw material and energy acquisition stagesdFor direct energy consumption of production, LnIndirect energy consumption for transformer production, TnEnergy consumption for transportation of transformer finished product, F is energy carbon emission factor parameter, and P isdAnd F are all experimentally determined theoretical values, LnAre statistical analysis values. The total carbon emission generated in the production logistics link in the whole life cycle of the transformer can be calculated according to the carbon emission accounting model of the transformer.
According to the transformer production logistics carbon emission accounting method, the carbon emission accounting boundary of the transformer enterprise is cleared through carding, the carbon emission accounting list of the transformer enterprise is formed, energy consumption data generated in each link are collected and collected according to the accounting list, data collection can be complete and accurate, and therefore the carbon emission accounting result in the whole link is prevented from being large in error. By building a transformer carbon emission measuring and calculating model, all carbon emission generated in the whole life cycle of one transformer is automatically counted, complex and variable carbon emission influence factors in the transformer production process are clearly combed, and complex and huge whole-link carbon emission is calculated. The quantity linear regression analysis of the transformers is carried out, theoretical indirect energy consumption and carbon emission are converted, the defect that the indirect energy consumption cannot be accurately distinguished and determined in the traditional statistical process is overcome, and a theoretical basis is provided for transformer enterprise management and comprehensive energy consumption level assessment.
