A method for checking the correlation degree of carbon emission data of gas-fired units based on cumulative difference analysis

Abstract

The invention discloses a method for checking the correlation degree of gas unit carbon emission data based on cumulative difference analysis. Firstly, the real-time monitoring data of the carbon emission concentration of the gas unit is converted into instantaneous carbon emission data, and then the gas unit intake gas is calculated by using the product difference analysis method. Finally, according to the size of the correlation coefficient, the rationality of the correlation degree between the carbon emission monitoring data is judged, and the abnormality of the carbon emission data is checked. The calculation logic of the method of the present invention is simple, and can be used for on-site on-line monitoring, find abnormal monitoring data in time, remind the on-site operators to troubleshoot data faults, and ensure the reliability of the carbon emission monitoring data of gas-fired units from the source; at the same time, it can be based on the update frequency of on-site monitoring data Reasonable selection of the length of the correlation coefficient time period not only satisfies the sample size requirements of the cumulative difference analysis, but also can be applied to different business scenarios such as online detection and early warning of abnormal data, data validity judgment, and parameter correlation analysis.

Description

technical field [0001] The invention belongs to the technical field of continuous monitoring of flue gas emissions, and in particular relates to a method for checking the correlation degree of carbon emission data of a gas-fired unit based on cumulative difference analysis. Background technique [0002] In October 2011, in order to further encourage greenhouse gas-emitting enterprises to reduce carbon dioxide emissions and achieve carbon emission reduction targets at a lower cost, the National Development and Reform Commission officially determined that Beijing, Tianjin, Shanghai, Chongqing, Guangdong, Hubei, and Shenzhen will carry out carbon trading in seven provinces and cities Pilot work, and officially implemented the pilot in 2013. As of September 2017, the cumulative quota trading volume of the carbon emission trading pilot program reached 197 million tons of carbon dioxide equivalent, or about 4.5 billion yuan, and the pilot work has achieved remarkable results. On ...

Problems solved by technology

Under the situation that my country took the lead in starting the construction of the national carbon market with the power industry as a breakthrough, the existing carbon emission accounting method based on emission factors can no longer meet the requirements for accurate verification and timely reporting of carbon emissions, and continuous monitoring of carbon dioxide emissions should be used The system conducts accurate real-time carbon emission monitoring of thermal power units, and uses the actual measurement method to calculate carbon dioxide emissions online based on on-site monitoring data, improving the timeliness and accuracy of carbon emission accounting data
