摘要
为了优化机组运行水平,提高企业管理能力,构建了综合对标评价体系对机组进行打分评价。对七台超临界机组进行综合管理水平评价,应用层次分析法(AHP)对指标进行权重分析,使用灰色管理度分析法(GRA)进行打分评价。结果表明:各机组间安全性差别不大,部分机组出现主汽超温和管道超温现象;稳定性整体波动较大,安全性是稳定性的前提;除个别机组NH_(3)超标严重外,其余机组环保性水平较高;经济性与稳定性联系密切,D机组稳定性排名最低,同时经济性得分也最低;稳定性对综合管理水平评价影响最明显,E机组稳定性评分最高,综合水平排名也最高,D机组稳定性评分最低,综合水平排名也最低。机组综合对标评价可以有效反映机组安全性、稳定性、环保性、经济性的差异,促进生产管理水平的提高。
In order to optimize the operation level of units and improve the management ability of enterprises,a comprehensive evaluation system was established to evaluate the units.This paper evaluates the comprehensive management level of seven supercritical units,uses analytic hierarchy process(AHP)to analyze the weight of indexes,and uses grey management degree analysis(GRA)to evaluate.There is little difference in safety among units,some units have main steam over-temperature and pipeline over-temperature phenomenon,overall stability fluctuates greatly,safety is the premise of stability,except some units have serious NH_(3)over-standard,the other units have a higher level of environmental protection;the economy and stability are closely related,and Unit D has the lowest ranking in stability and the lowest economic score;and the stability has the most obvious influence on the evaluation of comprehensive management level,unit E has the highest stability score and the highest comprehensive level ranking,while unit D has the lowest stability score and the lowest comprehensive level ranking.The comprehensive benchmarking evaluation of units can effectively reflect the differences in safety,stability,environmental protection and economy of units,and promote the improvement of production management level.
