摘　　要：近年来,人们对环境保护越来越重视,国家也开始大力开展清洁高效能源的应用。2016年国家能源局公布了首批建设的20个太阳能光伏发电项目。本文以其中某50MW光热汽轮机为例,建立了轴系的连续质量模型,并采用传递矩阵法对该机组轴系振动特性进行了分析。计算结果表明,机组轴系振动特性满足设计规范要求,能够满足机组安全运行要求。In recent years,people pay more attention to environmental protection,the country starts to develop and apply clean and high efficient energy vigorously.In 2016,National Energy Administration announced the list of the first 20 solar thermal steam turbine projects.In this paper, a continuous mass model of the shaft system is established with a 50 MW unit as an example, and the vibration characteristics of the shaft system are analyzed by using the transfer matrix method. The calculation results show that the vibration characteristics of the shaft system meet the requirements of design specifications,and the safe operation of the unit is guaranteed.
