摘　　要：汽轮机通流部分改造是否可以达到预期效果在某种程度上取决于辅机系统对改造的适应性,因此分析与探讨关键辅机的适应性对确保机组增容改造后的安全经济运行具有重要意义。以某型300MW汽轮机的通流部分改造为实例,分析其部分辅机设备主要参数在改造前后的变化趋势,重点讨论关键辅机在汽轮机通流部分改造后其固有特性对机组性能的潜在影响,进而为优化改造方案提出建议,以期为同类机组增容改造提供参考。Whether the retrofit of flow passage of steam turbines could achieve the expectation effect depends on the auxiliary equipment applicability in a certain respect, so the analysis and investigation of the auxiliary equipment applicability is of gTeat significance in ensuring the safety and economical operation after the retrofit. Based on an example of retrofit of flow passage in a 500MW steam turbine, the variation tendency of some principal parameters of auxiliary equipments after retrofit is analyzed in this paper. The potential impacts on the unit performance from the inherent characteristic of the key auxiliary equipment after the steam turbine retrofit are discussed, thereby some suggestions in optimizing the retrofit plan are presented for the reference of the retrofitted units with the same type.
