[0194] Among them, G s Emissions related to the production and transportation of required replacement parts; d Emissions related to the production and transportation of consumables used; G eI = is the emission from the production and transportation stages of all parts of electrical equipment; s is the proportion of replacement parts required during the life cycle to all parts of electrical equipment; Q i is the amount of related consumables; g i The emission intensity of consumables.

[0195] (4) Demolition stage

[0196] 1) Building facilities

[0197] The dismantling phase of the substation needs to consider the recycling of materials. According to the life span of the materials, the recyclable materials have a loss rate Z. i In theory, the calculation of carbon emissions during the demolition phase is mainly divided into the carbon emissions generated by the energy consumption of demolition machinery and the transportation of waste materials, minus the carbon emissions of recyclable materials.

[0198]

[0199] In the formula, E c is the carbon emission during the demolition phase; Z i is the loss rate of recyclable materials.

[0200] 2) Power equipment

[0201] The calculation model for CO2 emissions during the dismantling and disposal phase of substation power equipment is:

[0202] Ge ab =G' d +G” t -G" c (18)

[0203] In the formula, Ge ab G' is the total emission during the dismantling and disposal phase of power equipment in substations; d Carbon emissions from dismantling construction and consumables; G′ t The carbon emissions associated with transportation for recycling and landfill after disassembly; G′ c To recycle carbon emissions from equipment and materials.

[0204] ① Dismantle and discharge G′ d The calculation model is:

[0205]

[0206] Where m is the type of energy used in the disassembly process, including electricity, fuel, etc.; Ep′ i is the energy consumption of the i-th energy source during the disassembly process; g′ p is the CO2 emission intensity of the i-th energy source in the disassembly process.

[0207] ② Recycling and landfill G″ t The calculation model is:

[0208]

[0209] Where n is the type of waste that needs to be processed after disassembly; Q ti The total weight of type i waste generated for recycling or landfill; L i is the distance between the construction site and the recycling facility or landfill site of the i-th type of waste; gt i is the emission intensity of the i-th type of garbage transportation.

[0210] ③Recyclable equipment and materials G″ c The calculation model is:

[0211]

[0212] Where k is the type of recycling equipment; E′ ki is the total number of recycled equipment of type i; S′ i is the actual recovery rate of recycled materials; g′ ci is the emission intensity of the i-th recovery equipment.

[0213] In step 3, the carbon emissions of the substation at each stage are summarized, mainly including the sum of carbon emissions from building materials and carbon emissions from power equipment, to obtain the total carbon emissions of the substation.

[0214]

[0215] In step 4, uncertainty analysis is performed on the assessment results, a confidence interval of the assessment results is proposed, and the carbon emission level of the substation is evaluated.

[0216] The Monte Carlo simulation method is used to randomly generate sample data and conduct uncertainty analysis on the carbon emission evaluation of the substation throughout its life cycle. In order to make the Monte Carlo simulation closer to the actual substation project, a data quality evaluation method is introduced to combine data information quantification with expert experience judgment, and then use some descriptive indicators to evaluate data uncertainty or reliability in a semi-parametric, semi-empirical method.

[0217] Five uncertainty factors are used as basic descriptive evaluation indicators, and a data quality evaluation table is developed (see Table 1). The 1 to 5 points represented by the indicator scores in the table are used to indicate data quality from low to high. The reliability classification of actual engineering data can be specifically divided into unknown or unevaluated data, data judged based on experience, data calculated based on quotas or BIM models, and indirect data on site and data directly measured on site.

[0218] Table 1 Data quality evaluation matrix

[0219]

[0220] The relationship between the semi-parametric probability distribution and the data quality score is obtained based on the Beta function, and the overall uncertainty of the data is expressed as variance, which is then used for uncertainty analysis of carbon emissions over the entire life cycle of the substation:

[0221]

[0222] Relevant researchers proposed the following conversion relationship between distribution parameters and comprehensive data quality scores based on expert experience:

[0223]

[0224] In the formula, S m is the comprehensive score of data quality; u is the representative value of the data calculation result.

[0225] The comprehensive scoring of data quality can adopt the average method, comprehensive evaluation method (AHP) and minimum method:

[0226]

[0227] In the formula, S m,i is the data quality score for indicator i; W F,i is the weight coefficient of indicator i.

[0228] The parameter uncertainty is divided into basic fixed uncertainty and additional uncertainty, and the corresponding data conversion relationship table is given by the above data conversion relationship, see Table 2.

[0229] Table 2 Conversion relationship between additional uncertainty and data quality

[0230]

[0231] The basic fixed uncertainty is generally the engineering data differences that cannot be eliminated, as well as random statistical and calculation errors, etc., but it can be determined through expert experience or some statistical methods; the source of additional uncertainty is generally the difference between inaccurate data measurement and calculation results, and also includes time, space and some related technical conditions, but the additional uncertainty can be determined through semi-parametric probabilistic methods such as data quality evaluation. For general projects such as building materials and mechanical energy consumption, the value of the basic uncertainty of the data expressed as variance can be taken as 0.0006; and the additional uncertainty can be obtained according to the data quality score by the semi-parametric probability distribution calculated by the following formula to obtain the conversion relationship in the above table, where:

[0232]

[0233] In the formula, is the value of the overall uncertainty of the data expressed as variance; is the value of the data basis uncertainty expressed as variance; Add uncertainty expressed as a variance to the data corresponding to indicator i.

[0234] The additional uncertainty variance obtained by this conversion relationship is only applicable to converting data quality indicators into lognormal distribution, and the distribution range of application is limited. Therefore, to represent other distributions, the degree of uncertainty needs to be expressed by the coefficient of variation. The conversion relationship table obtained by the above formula can be applied to some other distribution forms, such as normal distribution; in the lognormal distribution, the value of the coefficient of variation CV can be calculated according to the variance in the above table, and the conversion of the coefficient of variation of each data indicator has been attached to the above table.

[0235]

[0236] The overall uncertainty of the parameter, CVt, can be calculated as follows:

[0237]

[0238] The basic uncertainty CV b The value directly calculated based on the data basic uncertainty expressed in variance is 0.051; the additional uncertainty comprehensive coefficient of variation CV a The value of can be calculated according to the above table and the following formula:

[0239]

[0240] Normal distribution parameter transformation:

[0241]

[0242] Where, σ = μCV t ; μ is the representative value of the data.

[0243] Taking a 220 substation as an example, the calculation results of its carbon emissions are shown in the following table. The total carbon emissions are 105604.2tCO2e; while the mean of 10,000 Monte Carlo random simulations is 107716.3tCO2e, with a relative error of 0.02%, which is relatively small.

By collecting various consumption data of various raw material equipment in the substation during production, transportation, operation and decommissioning, considering the uncertainty factors of data collection and carbon emission factor selection, giving the confidence interval of the evaluation result, and improving the reliability of the calculation result, the carbon emission result of the present invention is highly accurate and has good operability.
