汽轮机转子寿命损耗在线监测系统开发及应用

摘要

基于有限差分法，采用MATLAB和组态软件开发了基于火电厂SIS数据平台的汽轮机组寿命在线监测系统，实时考虑放热系数变化，转子材料物性变化等因素。通过现场运行，结果表明该系统能很好的反映出转子温度场及应力场分布，可以为机组的安全、经济运行及寿命管理提供有效的技术手段，能够很好地满足工程实际需要。%Based on the finite difference method,the online life loss monitoring system was developed by using Matlab and Configuration software tools, basing on data center platform of SIS, the real -time heat transfer coefficient and the rotor material properties changes and other factors have been considered.The actual field operations showed that the system can well reflect the distribution of temperature field and stress field.The system can provide effective technical means for the safe, economical operation and life management for the steam turbine,can effectively meet the needs of engineering practical.
