摘要(Abstract)：

国内300MW及以上容量机组增效扩容改造以后,部分辅机设备存在未能适应机组扩容要求的情况。以某发电厂600MW机组汽轮机扩容改造为实例,基于机组超额定出力试验和主要辅机设备参数变化趋势,分析了机组扩容后汽机、锅炉主要辅机和电气设备存在的问题,提出合理的建议,保证机组扩容后的稳定运行。
After efficiency upgrade and capacity expansion of the domestic 300MW or larger capacity units,some auxiliary equipments cannot meet the requirements of capacity expansion. This paper takes capacity expansion of 600MW steam turbine as an example and analyzes problems in steam turbine, main boiler auxiliary and electrical equipment after capacity expansion on the basis of rated output of boiler and parameter change of main auxiliary equipment; furthermore, it proposes reasonable suggestions to guarantee operation stability of units after capacity expansion.
