电站锅炉非计划停运时数分配不等性分析

Distribution Unequalness Analysis of Utility Boiler Uncheduled Shutdown Hours

本文提出了单元机组(或设备)非计划停运时数分配不等性分析的统计模型——非计划停运状态分布特性曲线和不均匀系数,并使用该模型计算了华东电网48台100MW以上单元机组和对应的锅炉设备的非计划停运时数分配的不均匀系数,以此对该电网非计划停运时数分配不等性的程度作出了判断。

A statistical model involving unscheduled shutdown state distribution characteristics and non-uniformity factor is provided for the unequalness analysis of unscheduled shutdown hours of monoblock unit (or equipment). With the help of such a model the unscheduled shutdown hour distribution non-uniformity factor of 100 MW monobloek units (totaling 48 together with corresponding boiler units) of Eastern China Electric Network has been calculated with the extent of the said Network unscheduled shutdown hour distribution unequalness being evaluated.
