摘　　要：汽轮机调节级的变工况计算是汽轮机热力计算中的主要内容。提出了一种改进方法,用于快速计算汽轮机调节级变工况的特性曲线,并以某型50MW汽轮机为例进行了对比计算。相比之前的方法,改进后的方法计算精确度有所提高。The calculation of off-design condition of steam turbine governing stage is the main issue in turbine thermodynamic calculation. An improved method of quick calculation for the characteristic curve of steam turbine governing stage in off-design condition is presented, and contrast calculation using a 50MW steam turbine as an example is conducted. Compared to the previous method, the improved method has better accuracy.
