| 摘 要： | 对2013年100 MW及以上火电机组非计划停运次数及持续时间进行了统计与分析。机组共发生非计划停运920次，总持续时间53 443.5 h。其中因锅炉及其辅助设备所导致的非计划停运次数达到500次以上，因汽轮机系统导致的非计划停运次数为150次以上。通过对锅炉、汽轮机等系统非计划停运原因的分析，找出了影响火电机组可靠性的相对薄弱环节，为加强对机组可靠性薄弱部位的日常维护管理提供了参考和依据。

| Abstract: | The times and total duration of unplanned outages of thermal power units with the capacity of 100 MW grade and above in 2013 are counted and analyzed. The total times of unplanned outages of all the units are 920, and the total duration of unplanned outages is 53 443.5 hours. The times of unplanned outages caused by boilers and the boiler auxiliary equipment are more than 500, while the ones caused by turbine systems are more than 150. Through the analysis on the reasons for the unplanned outages caused by the boiler and turbine systems, the relative weak deficient parts that affect the unit reliabilities are figured out, which can provide the reference and basis for improving the routine maintenance and management of those deficient parts with poor reliabilities. |
