摘　　要：基于机组寿命损耗机理,对汽轮机转子寿命损耗的在线监测进行了研究。首先结合有限元分析软件分析结果确定转子应力在线监测的监测面位置及其他重要参数,其次引入有限差分法对转子进行分层建模,建立了转子应力及寿命损耗的在线监测模型。在理论研究的基础上,通过.Net平台采用B/S/S 3层模式开发了基于SIS数据平台的机组寿命监测系统,并应用于某电厂600 MW机组,现场实际运行表明该系统能较好地反映机组转子的温度场和应力场分布,并能在线计算转子寿命损耗,给出可靠的运行指导。The turbine rotor online life expenditure monitoring system based on the life loss theory was studied in this paper.Firstly,the online monitoring surface position and some key parameters were confirmed according to the results of finite element analysis software.Secondly,the online monitoring model of stress and life loss of turbine rotor was built through hierarchical modeling with the finite difference method.Finally,on the basis of theoretical research,the online life loss monitoring system,developed by using data center platform of SIS and B/S/S mode on.NET platform,was applied to a 600MW unit.The onsite operation showed that the system could well reflect the distribution of temperature field and stress field,calculate the life expenditure,and provide reliable operation guidance.
