| 摘 要： | 目前,国内积累了大量关于火电机组的可靠性数据,但对它们的统计分析还远远不够。作者对600MW机组的某些可靠性数据进行了统计分析并应用最小二乘法建立了数学模型,同时对该模型进行了分析和应用,发现600MW机组的非计划停运小时、强迫停运小时、降低出力等效停运小时和等效强迫停运率EFOR基本上是按逐年递减的规律变化的,而其等效可用系数则是逐年递增的。

| Abstract: | A lot of data of reliability are stored at present, but only a few of them are used to analyse statistically. Some data of reliability in 600MW units are analysed statistically and methmatic models are built by using least squares in this article. The application of the model is discussed. It is found that in 600MW units UOH, EUNDH and EFOR is decreased and EAF increased year after year. |
