单元机组非计划停运时数分配不等性分析

Analysis on Unequal Distribution of Unplanned Outage Time of Generating Unit

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以上单元机组在1982年1月至1987年12月间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 for analysis of unequal distribution of unplanned outage hour of generating unit (or other equioment).which includes the characteristic curve of unplanned Outage mode and the unequal factor. was developed in this paper. The unequal factors of unplanned outage hours distribution of 48 units(100MW and up) in ECPN from Jan. 1982 to Dec. 1987 were calculated using this model and an evaluation of the degree of unequal distribution in unplanned outage hours in ECPN was carried out.
