Problems solved by technology

The method fails to cover SF containing 6 All aspects of carbon emissions from electrical equipment, in fact SF 6 Emissions also exist in SF-containing 6 Installation process of electrical equipment, SF 6 Purification process after recovery and recharging process after purification
In addition, the method simply uses the equipment nameplate capacity as the SF 6 content is not accurate

Abstract

The present invention discloses a method for accounting the carbon emission of sulfur hexafluoride-containing electrical equipment in an electric network system. The method comprises: S1, determining organization boundaries; S2, determining operation boundaries; and S3, establishing a quantification method. According to the present invention, the complete method for accounting the carbon emission of SF6-containing electrical equipment is established, the problem of inaccuracy of the single emission factor calculation is effectively avoided, the accurate calculation method for the SF6 content after the refilling in the electrical equipment is solved, the carbon emission of the SF6-containing electrical equipment in the electric network system at each stage is completely covered, the accurate accounting method is established for the tracking of the emission data of the SF6-containing electrical equipment at the life cycle stage by the electric network enterprise, the evaluation and management control measures for the SF6 emission can be easily established, and the influence of the SF6 emission on the climate change can be reduced.

Description

technical field [0001] The invention relates to a method for calculating the carbon emission of electrical equipment containing sulfur hexafluoride in a power grid system. Background technique [0002] Sulfur hexafluoride (SF 6 ) gas is widely used in electrical equipment in power transmission and distribution systems because of its excellent electrical insulation and arc extinguishing properties. But SF 6 The greenhouse effect of the gas is CO 2 It is 23,900 times that of carbon dioxide and can exist stably in the atmosphere for 3,200 years. It is one of the six greenhouse gases that are restricted in the Kyoto Protocol. [0003] The Intergovernmental Panel on Climate Change (IPCC) compiled the "2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC 2006)", proposing national-level SF 6 Emission estimation methods: emission factor method and mass balance method. For the emission factor method, the guidelines only provide the default values ​​of emission fac...
