摘　　要：选取安徽省34家燃煤电厂作为研究对象,对其气态污染物中NO_x数据传输至省电力公司的数据与省环保厅的数据进行比对核查。通过分析发现NO_x重复换算、标准氧重复折算、数据采集时间点差异、数据采集频次差异、采集传输仪表量程变更等问题是造成NO_x折算值存在着一定差异的主要原因,并提出了相应的解决方法。研究结果对提高CEMS数据传输的准确性和真实性,同时对提高电厂CEMS运行和管理有一定的指导意义。This article selects 34 coal-fired power units as the research object in Anhui,compare the gaseous pollutants of NOx data transmission to the provincial Grids and the department of environmental protection.Through the analysis found that NOx and standard oxygen repetitive conversion,data acquisition time and frequency difference,and gathering transmission instrument range change are the reason of differences between NOx conversion value,and propose the corresponding solution. The research results improved the accuracy and authenticity of CEMS data transmission,and has a certain guiding in improve the CEMS of operation and management in coal-fired units.
