摘　　要：论述了国产引进型 30 0MW汽轮机起停调峰运行时出现的问题和改进对策 ,并对其冷态起动的冲转参数选择、中速暖机、起动方式的改进 ,以及热态起动、停机等进行了分析。根据该型汽轮机的特点 ,提出了提高参与起停调峰运行汽轮机安全性和经济性的对策。The selection of rotorimpulsing parameters during coldstate starting, warmingup at medium speed, improvement of starting mode, as well as hotstate startup and shutdown etc. of homemade imported type steam turbine of 300MW unit have been analysed and expounded. Based on features of this type steam turbine, countermeasures for enhancing safe and economic behavier of peakload regulating operation by starting and stooping the said steam turbine have been put forward.
