Abstract : based on the operation data , the cold start - up and warm start - up curves of a czecho 200 mw steam turbine are worked out according to the operation rules ; the fem calculating models of the temperature field and stress field of the high pressure rotor are established , and the suitable boundary conditions are given ; the temperature field and stress field of the high pressure rotor are calculated and analysized during these two working situation 文摘:在现场实测数据的基础上，根据运行规程拟定捷制200mw机组的冷态启动和温态启动曲线；建立高压转子温度场和应力场有限元计算模型，确定相应的边界条件；计算分析在这两种工况下高压转子的温度场和热应力场。
