[0044] The embodiment of the present invention provides a method for calculating carbon emissions during a photovoltaic maintenance process. Figure 1 As shown, the specific steps include:

[0045] S101. Receive the accounting boundary of a photovoltaic maintenance process and information on carbon emission sources during the photovoltaic maintenance process.

[0046] The accounting boundary includes the accounting maintenance items and the accounting time; the accounting time is the period of this carbon emission accounting, and all carbon emission activities calculated by the present invention occur within the accounting time. The carbon emission source information during the photovoltaic maintenance process includes at least one carbon emission source during the photovoltaic maintenance process.

[0047] The accounting maintenance items include but are not limited to photovoltaic module maintenance, photovoltaic bracket maintenance, junction box maintenance, inverter maintenance, transformer maintenance, switch cabinet maintenance, monitoring and communication system maintenance, DC and AC control power supply maintenance, relay protection and safety automatic device maintenance, battery maintenance, reactive power compensation device maintenance, fire protection and security system maintenance, lightning protection device maintenance, power cable maintenance, etc. during the photovoltaic power maintenance process. No limitation is made here.

[0048] Sources of carbon emissions during photovoltaic maintenance include, but are not limited to, emissions from net purchased electricity and heat, emissions from fossil fuel combustion (including the use of maintenance transportation vehicles), carbon emissions from the repair and decommissioning of sulfur hexafluoride equipment, emissions from fire drills or fire extinguisher filling, fugitive emissions from air conditioning refrigerant filling, waste disposal emissions, etc., which are also not limited here.

[0049] S102. Collect carbon emission analysis data based on all accounting maintenance items, accounting time, and carbon emission sources during the photovoltaic maintenance process.

[0050] As shown in Table 1, it is a statistical table of carbon emission analysis data provided by the present invention.

[0051]

[0052]

[0053]

[0054] Table 1

[0055] S103. For each carbon emission source in the photovoltaic maintenance process, the carbon emission of the carbon emission source is calculated based on the carbon emission analysis data of the carbon emission source.

[0056] Optionally, in the specific implementation of the present invention, different calculation methods are used for carbon emissions from different carbon emission sources:

[0057] (1) The carbon emissions from the net purchased electricity used for maintenance operations during the accounting period can be calculated based on, but not limited to, the net purchased electricity used for maintenance operations during the accounting period and the grid emission factor.

[0058] It should be noted that during the photovoltaic power maintenance process, the activity level data required for the calculation of carbon emissions from net purchased electricity is the purchased electricity measured during the maintenance carbon accounting period. Therefore, in the specific implementation of the present invention, the carbon emissions of net purchased electricity used in the maintenance operation during the accounting period can be calculated using the following calculation formula: 电力 :

[0059] C 电力 =∑AD 电力 ×EF 电力

[0060] Among them, C 电力 The carbon emissions of the net purchased electricity used for maintenance operations during the accounting period, in tons of carbon dioxide equivalent (tCO2e); AD 电力 The net amount of electricity purchased for maintenance operations during the accounting period, in megawatt-hours (MWh); EF 电力 is the grid emission factor, unit: tons of carbon dioxide / MWh (tCO2 / MWh).

[0061] It should be noted that the net purchased electricity used for maintenance operations during the accounting period includes the total amount of electricity consumed in the entire maintenance process, including fault handling, testing, replacement, etc., minus the waste heat power generation and self-provided power plant power generation provided by the maintenance project for the maintenance operation. The renewable energy power and purchased green power used in the maintenance operation during the accounting period are included in the carbon emission offset. The acquisition of electricity emission factor data uses the average carbon emission factor data of the power grid where the maintenance project is located.

[0062] (ii) The carbon dioxide emissions from the net purchase of heat during the accounting period can be calculated based on, but not limited to, the net heat purchased during the accounting period and the carbon dioxide emission factor of the purchased heat.

[0063] In the specific implementation process of the present invention, the carbon dioxide emissions generated by the net purchased heat during the accounting period can be calculated by the following calculation formula:

[0064] C 热力 =AD 热力 ×EF 热力

[0065] Among them, C 热力 The carbon dioxide emissions generated by the net purchase of heat during the accounting period, unit: tons of carbon dioxide equivalent (tCO2e); AD 热力The net amount of heat (steam, hot water) purchased during the accounting period, unit: GJ; EF 热力 is the carbon dioxide emission factor of the purchased heat (steam, hot water), unit: tons of carbon dioxide / gigajoule (tCO2 / GJ). 热力 =AD 蒸汽 +AD 热水 , A.D. 蒸汽 The net amount of heat purchased from steam during the accounting period, unit: GJ; AD 热水 It is the net amount of hot water purchased during the calculation period, unit: GJ.

[0066] It should be noted that the purchased steam and hot water measured in mass units should be converted into heat units. The net consumption of purchased heat (steam, hot water) during the maintenance accounting period should be the sum of the heat consumed in all maintenance processes such as troubleshooting, testing, and replacement. The net purchased cooling capacity during the maintenance accounting period (within the accounting time) only considers the cooling form converted from heat, and its carbon emissions are uniformly calculated based on the purchased heat. The net purchased heat during the maintenance accounting period is the total heat used for maintenance (including cooling converted from heat) minus the self-used heat produced by burning fossil fuels during the maintenance process (this part is included in the fossil fuel combustion emissions), and the self-used heat generated by the utilization of waste heat during the maintenance process. The emission factor for purchased heat is 0.11tCO2 / GJ, or the latest value published by the national government department in charge and the government where the maintenance project is located.

[0067] (3) Greenhouse gas emissions from the combustion of fossil fuels during the accounting period can be calculated based on, but not limited to, the global warming potential of greenhouse gases produced by the combustion of each fossil fuel during the accounting period and the amount of greenhouse gas emissions.

[0068] It should be noted that greenhouse gases emitted from fossil fuel combustion mainly come from the emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) produced by fossil fuel combustion equipment during the maintenance of photovoltaic power equipment and the driving of transportation vehicles using fossil fuels such as gasoline and diesel.

[0069] Greenhouse gas emissions from fossil fuel combustion can be calculated using the following formula:

[0070] C 化石 =∑(E i ×GWP i )

[0071] Among them, C 化石 It is the greenhouse gas emissions from the combustion of fossil fuels during the accounting period, in tons of carbon dioxide equivalent (tCO2e); E i is the emission of the ith greenhouse gas, E 二氧化碳、E 甲烷 、E 氧化亚氮 Composition, E 二氧化碳 The unit is tons of carbon dioxide (tCO2), E 甲烷 The units are tons of methane (tCH4), E 氧化亚氮 The unit is tons of nitrous oxide (tN2O); GWP i is the global warming potential of greenhouse gases produced by the combustion of the i-th fossil fuel; i is the type of greenhouse gas. The GWP values ​​of different greenhouse gases can refer to the latest data provided by the Intergovernmental Panel on Climate Change (IPCC).

[0072] It is understandable that the CO2 emissions from fossil fuel burning equipment and maintenance transportation vehicles using fossil fuels such as gasoline and diesel can be calculated by adding up the CO2 emissions from the combustion of different fossil fuels, and the calculation formula is as follows:

[0073] E 二氧化碳 =∑(AD i ×EF i )

[0074] Among them, E 二氧化碳 AD is the carbon dioxide emissions from the combustion of fossil fuels, measured in tons of carbon dioxide (tCO2); i is the activity data of the i-th fossil fuel, in GJ; EF i is the carbon dioxide emission factor of the ith fossil fuel, expressed in tons of carbon dioxide per gigajoule (tCO2 / GJ).

[0075] Since the fossil fuel activity level data that causes carbon dioxide gas emissions is calculated by multiplying the net consumption of various fossil fuels during the maintenance accounting period by the average low-level calorific value, it can be calculated according to the following formula:

[0076] AD i =NCV i ×FC i

[0077] Among them, NCV i is the average lower calorific value of the ith fossil fuel, in GJ / t for solid and liquid fuels and GJ / 10 4 Nm 3 );FC i is the net consumption of the ith fossil fuel, in tons (t) for solid and liquid fuels and in 10,000 standard cubic meters (10 4 Nm 3The lower calorific value of each fuel should adopt the local measured value. If the measured value is unavailable, the standard recommended value can be used.

[0078] The carbon dioxide emission factor due to fossil fuel combustion that causes carbon dioxide gas emissions can be calculated according to the following formula:

[0079] Among them, CC i is the carbon content per unit heat of the i-th fossil fuel, in tons of carbon dioxide per gigajoules (tCO2 / GJ); i is the carbon oxidation rate of the i-th fossil fuel, expressed in %. 44 / 12 is the ratio of the molecular weight of carbon dioxide to carbon. The carbon content of the fuel can be tested regularly, and the determination of the carbon content of the fuel should comply with relevant national standards. For common commercial fuels, the carbon content per unit calorific value and the carbon oxidation rate can use industry data or recommended values.

[0080] It should be noted that the calculation formula for methane and nitrous oxide gas emissions caused by fossil fuel combustion equipment and maintenance transportation vehicles using diesel, gasoline and other fuel oils during driving is as follows:

[0081] (1) Methane emissions from fossil fuel combustion are calculated as follows:

[0082] E 甲烷 =∑(D i ×CF i )

[0083] Among them, E 甲烷 is the nitrous oxide emissions from fossil fuel combustion, expressed in tons of methane (tCH4), D i is the net fossil fuel consumption of the i-th vehicle. It should be noted that fossil fuels are divided into solid fossil fuels, gaseous fossil fuels and liquid fossil fuels. For solid fossil fuels, D i The unit is tons (t); for liquid fossil fuels, D i The unit is liter (L); for gaseous fossil fuels, D i The unit is ten thousand standard cubic meters (10 4 Nm 3 );CF i is the methane emission factor of the i-th fossil fuel, with the unit of ton of methane per ton (tCH4 / t) for solid fossil fuels, ton of methane per liter (tCH4 / L) for liquid fossil fuels, and ton of methane per 10,000 standard cubic meters (tCH4 / 10 4 Nm 3 ).

[0084] (2) Nitrous oxide emissions from fossil fuel combustion are calculated as follows:

[0085] E 氧化亚氮 =Σ(D i ×NF i )

[0086] Among them, E 氧化亚氮 is the nitrous oxide emissions from fossil fuel combustion, measured in tons of carbon dioxide (tN2O); D i is the net fossil fuel consumption of the i-th vehicle. It should be noted that fossil fuels are divided into solid fossil fuels, gaseous fossil fuels and liquid fossil fuels. For solid fossil fuels, the unit is ton (t); for liquid fossil fuels, the unit is liter (L); for gaseous fossil fuels, the unit is ten thousand standard cubic meters (10 4 Nm 3 );NF i is the nitrous oxide emission factor for the i-th fossil fuel. For solid fossil fuels, NF i The unit is ton of nitrous oxide per ton (tN2O / t); for liquid fossil fuels, NF i The unit is tons of nitrous oxide per liter (tN2O / L); for gaseous fossil fuels, NF i The unit is tons of nitrous oxide per 10,000 standard cubic meters (tN2O / 10 4 Nm 3 ).

[0087] It should be noted that for the net consumption of fuel, the data measured by monitoring personnel shall be used, and the relevant measuring instruments shall comply with the requirements of GB17167 "General Rules for the Equipment and Management of Energy Measuring Instruments for Energy-consuming Units". For the determination of the average lower calorific value, unit calorific carbon content and carbon oxidation rate of fossil fuels, the recommended values ​​may be used.

[0088] (IV) Carbon emissions generated during the repair and decommissioning process of sulfur hexafluoride equipment during the accounting period can be calculated based on, but not limited to, the sulfur hexafluoride capacity and actual amount of sulfur hexafluoride recovered of each retired equipment during the accounting period, the sulfur hexafluoride capacity and actual amount of sulfur hexafluoride recovered of the repaired equipment, and the gas potential of sulfur hexafluoride.

[0089] It should be noted that during the maintenance of photovoltaic power plants, the carbon emissions generated by the repair and decommissioning of sulfur hexafluoride equipment can be calculated according to the following formula:

[0090]

[0091] Among them, C SF6 REC is the carbon emissions generated during the repair and decommissioning of sulfur hexafluoride equipment during the maintenance process, measured in tons of carbon dioxide equivalent (tCO2e); 容量,i is the sulfur hexafluoride capacity of the retired equipment i, expressed in kilograms (kg) according to the nameplate data; REC 回收,iis the actual amount of sulfur hexafluoride recovered from the retired equipment i, in kilograms (kg); REC 容量,j The sulfur hexafluoride capacity of repair equipment j, expressed as the nameplate data, in kilograms (kg); REC 回收,j The actual amount of sulfur hexafluoride recovered to repair equipment j, in kilograms (kg); GWP SF6 The SF6 gas potential of sulfur hexafluoride.

[0092] (V) Carbon emissions from fire drills or filling of fire extinguishing systems during the accounting period can be calculated based on, but not limited to, the carbon emissions from carbon dioxide fire extinguishers, carbon emissions from gaseous fire extinguishing agents, and carbon emissions from filling of fire extinguishing systems during the accounting period.

[0093] It is understandable that during the maintenance of photovoltaic power plants, the emissions from fire drills or filling of fire extinguishers are the sum of the carbon emissions generated by the filling of the corresponding fire extinguishing system, the carbon dioxide fire extinguishers and the carbon emissions of gas fire extinguishing agents in the fire drills, which can be calculated according to the following formula:

[0094] C 消防 =C 二氧化碳 +C 气体药剂 +C 填充

[0095] Among them, C 消防 Carbon emissions for fire drills or filling fire extinguishing systems, in tons of carbon dioxide equivalent (tCO2e); C 二氧化碳 is the carbon dioxide fire extinguisher carbon dioxide emission, the unit is tons of carbon dioxide equivalent (tCO2e); C 气体药剂 is the carbon emission of gas fire extinguishing agent, in tons of carbon dioxide equivalent (tCO2e); C 填充 Carbon emissions for filling the fire suppression system, measured in tonnes of carbon dioxide equivalent (tCO2e).

[0096] 1. The carbon emissions of carbon dioxide fire extinguishers during fire drills are calculated according to the following formula:

[0097] C 二氧化碳 =N×m 二氧化碳 / 1000

[0098] Where: C 二氧化碳 is the carbon dioxide fire extinguisher carbon dioxide emission, the unit is tons of carbon dioxide equivalent (tCO2e); N is the number of carbon dioxide fire extinguishers used, the unit is m 二氧化碳 The amount of carbon dioxide required for each carbon dioxide fire extinguisher, in kilograms per extinguisher (kg / extinguisher).

[0099] 2. The carbon emissions of gas fire extinguishing agents during fire drills are calculated according to the following formula:

[0100] C 气体药剂 =FC气体药剂 ×GWP 气体药剂 / 1000

[0101] Where: C 气体药剂 is the carbon emission of gas fire extinguishing agent, in tons of carbon dioxide equivalent (tCO2e); FC 气体药剂 The amount of extinguishing agent used in the gas fire extinguishing system, in kilograms (kg); GWP 气体药剂 is the global warming potential of greenhouse gases of gaseous fire extinguishing agents.

[0102] 3. Carbon emissions generated by filling the fire extinguishing system are calculated according to the following formula:

[0103] C 填充 =Σ(D j ×E j ×GWP j )

[0104] Where: C 填充 Carbon emissions for filling the fire extinguishing system, in tons of carbon dioxide equivalent (tCO2e); D j is the filling amount (usage) of the jth maintenance process during the maintenance process, in tons (t); E j is the dissipation factor of the filler in the jth maintenance process; GWP j is the global warming potential of greenhouse gases emitted by the jth filler, in kilograms of carbon dioxide equivalent per kilogram (kgCO2e / kg).

[0105] D of the stock fire extinguishing system j According to the inventory, for the D of the fire extinguishing system used j Calculated as the difference between purchase quantity and inventory quantity.

[0106] (VI) Carbon emissions generated by refrigerant filling of air conditioners during the accounting period can be calculated based on, but not limited to, the refrigerant filling amount during the maintenance process of each air-conditioning unit during the accounting period, the refrigerant escape factor, and the global warming potential of greenhouse gases generated by the escape of refrigerant from the air conditioner.

[0107] In the implementation process of the present invention, the carbon emissions generated by filling the air conditioning refrigerant during the photovoltaic power maintenance process can be calculated according to the following formula:

[0108] C 冷媒 =∑(D vj ×EF j ×GWP j )

[0109] Where: C 冷媒 Carbon emissions from recharging air conditioners, measured in tons of carbon dioxide equivalent (tCO2e); D vjis the refrigerant filling amount (usage) of the jth air-conditioning unit during the maintenance process, in tons (t); EF j is the refrigerant escape factor of the jth air-conditioning unit; GWP j is the global warming potential of greenhouse gases generated by the escape of the j-th air-conditioning refrigerant, in kilograms of carbon dioxide equivalent per kilogram (kgCO2e / kg). It should be noted that the greenhouse gas filling amount (usage amount) of the refrigeration equipment is calculated by the difference between the purchase amount and the inventory amount.

[0110] (VII) The amount of greenhouse gas emissions generated by waste treatment during the accounting period can be calculated based on, but not limited to, the amount of emissions of each greenhouse gas generated by waste treatment during the accounting period.

[0111] It should be noted that if there is waste treatment during the maintenance of photovoltaic power, the greenhouse gas emissions generated during the waste treatment should be included in the total carbon emissions of the maintenance process. Waste treatment during the maintenance process includes solid waste treatment and sewage treatment. Greenhouse gas emissions from waste treatment mainly include methane (CH4) emissions from solid waste landfill treatment, carbon dioxide (CO2) emissions from solid waste incineration, and methane (CH4) and nitrous oxide (N2O) emissions from sewage treatment. Greenhouse gas emissions from solid waste incineration should be equal to the sum of carbon dioxide emissions from the incineration of mineral carbon in the waste, carbon dioxide emissions implied by net purchased electricity and heat, and fossil fuel combustion emissions from ignition or auxiliary fuel addition. If there are waste incineration power generation facilities in the incineration site, the carbon emissions generated by its own or externally supplied electricity and heat should be deducted from the total emissions. Methane emissions from solid waste landfills and methane emissions and nitrous oxide emissions from domestic sewage treatment should be calculated in accordance with national and industry standards and specifications. Greenhouse gas emissions generated by waste treatment should be converted from global warming potential (GWP) into carbon dioxide equivalent and included in the total carbon emissions of the maintenance process.

[0112] The greenhouse gas emissions generated by waste treatment during the maintenance process can be calculated according to the following formula:

[0113] C 废弃 =∑(EW i ×GWP i )

[0114] Where: C 废弃 EW is the greenhouse gas emissions generated by waste treatment during the accounting period, in tons of carbon dioxide equivalent (tCO2e); i is the i-th greenhouse gas emission generated by waste treatment, unit: ton (t); i is the type of greenhouse gas.

[0115] S104. The sum of carbon emissions from all carbon emission sources is taken as the first carbon emission amount.

[0116] S105. Use the first carbon emission amount as the total carbon emission amount during the photovoltaic maintenance process.

[0117] In the actual implementation of this application, carbon emission sources include net purchased electricity, heat emissions, fossil fuel combustion emissions (including the use of maintenance transportation vehicles), carbon emissions from sulfur hexafluoride equipment repair and decommissioning, fire drills or fire extinguisher filling emissions, air conditioning refrigerant filling fugitive emissions, and waste treatment emissions. The carbon emission source information in step S101 includes at least one carbon emission source in the photovoltaic maintenance process. In other words, the carbon emission source information includes one or a combination of the above-mentioned carbon emission sources.

[0118] Assuming that the carbon emission source information includes two carbon emission sources, that is, any two emission source combinations of the above seven carbon emission sources, for example: carbon emissions from the repair and decommissioning process of sulfur hexafluoride equipment and emissions from fire drills or fire extinguisher filling, or emissions from net purchased electricity and heat, or emissions from fossil fuel combustion (including the use and maintenance of transportation vehicles) and waste treatment emissions..., according to the mathematical calculation formula, there are a total of combinations; assuming that the carbon emission source information includes three carbon emission sources, that is, any three emission source combinations of the above seven carbon emission sources, such as: carbon emissions from the repair and decommissioning process of sulfur hexafluoride equipment, fire drills or fire extinguisher filling emissions, and net purchased electricity; thermal emissions, fossil fuel combustion emissions (including the use of maintenance transportation vehicles) and waste treatment emissions... According to the mathematical calculation formula, there are a total of Assuming that the carbon emission source information includes four carbon emission sources, according to the mathematical calculation formula, there are a total of Assuming that the carbon emission source information includes five carbon emission sources, according to the mathematical calculation formula, there are a total of Assuming that the carbon emission source information includes six carbon emission sources, according to the mathematical calculation formula, there are a total of Assuming that the carbon emission source information includes seven carbon emission sources, according to the mathematical calculation formula, there are a total of Combinations. That is, a total of For each carbon emission source in the carbon emission source combination, the carbon emission of the carbon emission source is calculated, and the sum of the carbon emissions of all carbon emission sources is taken as the first carbon emission. Finally, the first carbon emission is taken as the total carbon emission of the photovoltaic maintenance process.

[0119] For example: the carbon emission source information only includes one carbon emission source: fugitive emissions from the filling of air-conditioning refrigerant. In this case, you only need to collect the carbon emission analysis data of fugitive emissions from the filling of air-conditioning refrigerant: the refrigerant filling amount, refrigerant fugitive factor and global warming potential of greenhouse gases generated by the fugitive emissions of air-conditioning refrigerant during the maintenance process of each air-conditioning unit within the accounting time. Based on the above carbon emission analysis data, calculate the carbon emissions generated by the filling of air-conditioning refrigerant. Since there is only one carbon emission source, the carbon emissions generated by the filling of air-conditioning refrigerant are directly taken as the first carbon emissions, that is, the total carbon emissions of the photovoltaic maintenance process.

[0120] For example, the carbon emission source information includes six carbon emission sources: carbon emission sources include net purchased electricity, heat emissions, fossil fuel combustion emissions (including the use of maintenance transportation vehicles), carbon emissions from the repair and decommissioning process of sulfur hexafluoride equipment, fire drills or fire extinguisher filling emissions, and fugitive emissions from air conditioning refrigerant filling. Then the carbon emissions of the above six carbon emission sources are calculated according to the calculation method provided in this application to obtain C 电力 , C 热力 , C 化石 , C SF6 , C 消防 , C 冷媒 , then the first emission = C 电力 +C 热力 +C 化石 +C SF6 +C 消防 +C 冷媒 , the first carbon emission is taken as the total carbon emission of the photovoltaic maintenance process C 总 .

[0135] C 抵消 =∑C 碳汇 +∑C 绿色电力 +∑C 市场交易

[0136] Where: C 抵消 is the carbon emission offset during the maintenance process, unit: tons of carbon dioxide equivalent (tCO2e); C 碳汇 is the total carbon sink, unit: tons of carbon dioxide (tCO2); C 绿色电力 The carbon emissions reduced by electricity produced by renewable energy power generation facilities can offset the carbon emissions generated by purchased electricity, unit: tons of carbon dioxide (tCO2); C 市场交易 It refers to the carbon emission offset amount obtained in the market trading center, such as purchasing green electricity and green certificates, unit: tons of carbon dioxide (tCO2).

The method for calculating the fourth corrected emission amount can refer to the method for calculating the second corrected emission amount in the above embodiment, which is also not described in detail here.

[0153] ⑦ Summarize and calculate the total carbon emissions during the maintenance process of photovoltaic power equipment.

[0154] The specific calculation formula can be as follows:
