巨型机组补气系统研究

Research on air admission system for large generator units

本文探讨了巨型机组的选用原因及可能会遇到的不稳定运行,对传统意义上的机组稳定运行的含义进行了更深刻的剖析和拓展,研究探讨了如何应对不稳定运行的措施,提出了机组补气时补气量计算的数学模型,并进行了数值模拟计算及结果分析,为其他电站或运行情况类似机组提供借鉴及预防的经验与措施,同时,为进行相关领域的研究工作开拓了新的思路。

The reason of chosing large units,the unstability of large units operation and the implication of stability operation are discussed. The calculating models for air admission to prevent the units from unstable operation and the simulation calculation and analysis results are performed. The above results can be used for reference to other similar units of hydropower station.
