不同计量方法对燃气机组碳排放监测的影响分析
Analysis of the Influence of Different Measurement Methods on Carbon Emission Monitoring of Gas-Fired Units
摘要
Abstract
Gas turbine units will play an important supporting and regulating role in the new power system for a long time.Conducting precise monitoring of carbon emissions from gas turbine units can not only optimize the operation and management of these units but also support their participation in the carbon market trading.Based on the common carbon emission measurement methods(monitoring method and emission factor method),a digital monitoring method based on machine learning and online monitoring and an online calculation method based on supervisory information system(SIS)online data and emission factors of power plants are proposed.Taking a gas unit as the research object,CO2 emission are obtained through four measurement methods(manual accounting based on guidelines,online accounting,online monitoring based on cold and dry method and dilution method,and digital monitoring)during the statistical period.The accuracy of data from different monitoring methods is compared,and the conclusions are as follows:Carbon emission online accounting based on SIS online data and emission factor method is comparable with manual accounting CO2 emission amount,with an error rate of less than 1%.They can be used as references to achieve internal data verification within the factory;Both dilution and cold-dry online monitoring technologies can obtain accurate carbon emission volumes,but dilution need regular calibration to maintain measurement accuracy;A digital monitoring model established by a large number of operational data of the unit achievs real-time prediction of carbon emissions with high accuracy.When online monitoring data miss,it can provide guidance for unit operation and is expected to be promoted to similar types of units.关键词
