基于层次分析法的大型超临界火力发电机组优化运行分析

Analysis of Optimizing Operation of Large Supercritical Thermal Power Units Based on the Analytic Hierarchy Process

论文以大型超临界火力发电机组为研究对象,通过层次分析法对优化大型超临界火力发电机组可以采用的各项措施进行了分析。建立层次分析模型,再用两两比较法分析各措施分别对于经性、快速性、稳定性的影响比重,进而构造判断矩阵,最后通过层次总排序计算出四种措施的优先顺序,得到所讨论的四种措施相对优先排序为:材料、燃烧系统、启动系统、运行方式,通过论文的分析为实现大型超临界火力发电机组的优化运行提供了理论依据。

The various measure for optimizing large supercritical thermal power generating unit are analyzed by Analytic Hierarchy Process.A hierarchical model is established,and then the influence proportion of various measures is analyzed in economic,fast and stability by pairwise comparison method.Then judgment matrix is constructed,and the level sort table of four kind of measures is calculated.The conclusion is gotten that the sort of the four measures discussed is materials,combustion system,startup system,operation mode.So it can provide theoretical basis for the optimization of the large supercritical thermal power unit.
