摘　　要：针对某电厂1000MW引进型超超临界汽轮机的运行现状及改造的必要性进行了分析。对汽轮机通流部分改造方案进行了说明;对改造前后的性能数据结果进行了对比分析,从高、中压缸效率、热耗率及抽汽段级效率等方面对改造效果进行了评价。同时针对汽轮机改造存在的不足,给出了进一步提高经济性的措施建议,为后续同类型1000MW汽轮机通流改造提供借鉴和参考。This paper analyzes the operating status and the necessity of retrofit of the first-generation 1000MW imported steam turbine,and compares and analyzes the performance data results before and after the retrofit of the HP and IP turbine flow section of a plant's No.4 unit.The efficiency of the HP and IP turbine and heat rate have reached the design values of the manufacturer.At the same time,in view of the existing problems of the turbine,suggestions for further improving the economy are put forward,which provides reference for the follow-up 1000MW unit retrofit.
