摘　　要：采用克兰克-尼科尔森差分法对亚临界300 MW汽轮机进行了冷态启动过程的转子温度场仿真计算,通过其结果分析,提出了运行建议。该方法可直接用于转子温度场的在线计算,具有数据处理实时、准确、稳定性好等优点。Crank-Nicolson finite-difference method is used to calculate the temperature field in the rotor artificially during sub-critical 300MW steam turbine cold startup. By the analysis of the results, some suggestions of steam turbine operation are given. The method can be used directly in online calculation of temperature field of the rotor. Moreover, this method has the advantages of dealing with data fast and accurately, and the stability of the calculation is performed well.
