摘要
实时监测汽轮机转子疲劳损耗,能提高机组运行的安全性和机动性。重点论述了应用雨流法实时统计转子的应力循环,详细分析了雨流法原理和应用条件以及雨流法程序的实现方法,并采用300 MW机组实际启动过程进行实例计算,其结果能真实反映汽轮机转子启动载荷谱,从而提高转子疲劳损耗实时监测的真实性与灵敏度。
That monitoring the fatigue expenditure of turbine rotor can improve security and flexibility of the unit. The Rain-Flow Method counting stress circulation and the principle are discussed, finally it is applied on a 300MW unit start-process. The result can reflect actual stress-chart.
