摘要:

从广州某天然气发电厂2台S109FA型390MW级燃气-蒸汽联合循环机组的实际运行状况出发,分析影响该类机组发电热耗率变化的主要因素,借助PI数据库的历史数据查询功能,通过实例对各种影响因素的影响程度进行量化分析。量化分析结果验证了此种分析方法的有效性,同时也为机组的变工况特性量化分析提供了计算依据。

Abstract:

:Based on the actual operation conditions of two 390MW S109FA gassteam combined cycle generating units of a power plant in Guangzhou,it analyses the major influencing factors of thermal power consumption rate of power generation. According to the query function of historical data in PI database, quantitative analysis can be made on the influence of these factors through practical cases. The quantitative analysis result proves the availability of the analysis method above. At the same time,the result of  analytic procedure provides calculating basis for the quantitative analysis on the features of variable working condition of the units.
