摘要
Abstract
The times and total duration of forced outages of thermal power units with the capacity of 1 000 MW between 2012 and 2016 are counted and analyzed.There are 166 forced outages for all the units,and the total duration is 9 440.22 hours.The times of forced outages caused by boilers and their auxiliary equipments are 78 and the total duration is 5 409.22 hours,accounting for 57.30％ of the total forced outage time;while that caused by the turbine systems are 42 and the total duration is 3 060.85 hours,accounting for 32.42％ of the total forced outage time.The analysis of technical and liability reasons of the forced outages helps to find out the relative weakness which lowers the unit operating reliability and provides the reference and basis for improving the routine maintenance and management.关键词
