摘　　要：为实时掌握综合反映燃煤机组能耗及环保排放水平的特性,构建了考虑机组供电煤耗与大气污染物排放绩效的综合指标计算模型,提出了基于数据挖掘的兼顾能耗与环保的燃煤机组特性曲线的获取方法,并以1000 MW超超临界燃煤机组为例进行了验证和应用分析。结果表明:基于数据挖掘的兼顾能耗与环保的燃煤机组特性曲线能真实反映机组本身的节能减排特性,且随机组特性变化而变化,其为实现机组之间进行综合排序提供了便利。In order to monitor the characteristics of comprehensive reflection of energy consumption and environmental protection emission level of coal-fired units in real time,a comprehensive index calculation model considering the power supply coal consumption of units and the emission performance of air pollutants is constructed.Based on data mining,a method of obtaining the characteristic curve of coal-fired unit considering both energy consumption and environmental protection is proposed,and a 1000 MW ultra supercritical coal-fired unit is taken as an example for verification and application analysis.The results show that the characteristic curve of coal-fired unit considering energy consumption and environmental protection based on data mining can truly reflect the energy-saving and emission reduction characteristics of the unit itself,and change with the characteristics of the unit,which provides convenience for the comprehensive sequencing between units.
