摘　　要：采用开发的“大功率中间再热汽轮机热力性能和气动性能计算软件包和低压级组小容积流量流场、气动性能计算程序”,对沙角 A厂 30 0 MW汽轮机低压级组在小容积流量工况下性能进行计算和分析 ,预测了末级产生脱流工况的结果 ,可供调峰运行参考。图 9表 2参Performance computational analysis for LP section of Shajiao Power Plant's 300MW steam turbine operating under low volume flow condition is conducted, using the computational software package for thermal and pneumatic characteristics of high power double reheat steam turbines as well as the computational program for low volume flow (field) and pneumatic characteristics of LP section. The prediction results of the causes of the final stage stall are of referential value for peak and cyclic load operation. Figs 9, tables 2 and refs 6.
