随着国民经济的飞速发展,机组国产化进程的迅猛提高,研究适合国产机组故障诊断的方法具有重要理论意义和重大经济价值。汽轮发电机组是一个由锅炉、汽轮机、发电机三大设备,它主要由主轴、叶轮、动叶栅等组成,因而其工作的稳定性和安全性就显得格外重要,在运行过程中,利用模糊数学中模糊综合评判理论对汽轮机转子的故障进行诊断,用以确定病症,提高电力企业生产率。
With the rapid development of the national economy and the rapid increase of unit localization, it is of important theoretical significance and significant economic value to study the method suitable for the fault diagnosis of domestic units. Turbine generator set is a boiler, steam turbine, generator three major equipment, which is mainly composed of the spindle, impeller, moving cascade and other components, so its stability and safety of work is particularly important in the operation, the use of The theory of fuzzy comprehensive judgment in fuzzy mathematics diagnoses the fault of turbine rotor to determine the condition and improve the productivity of electric power enterprises.
