By comparing two types of feature reduction methods
the principal component analysis and the rough set theory
the integrated feature reduction of vibration fault diagnosis model of principal component analysis was established
applying the improved support vector machine platform.Taking the fault signal of oil film whirl vibration in a steam turbine and the mass unbalance vibration in a 600 MW unit steam turbine as the example
the new fault diagnosis method combing the principal component analysis with the improved support vector machine was verified.The results show that
this new fault diagnosis method not only can shorten the diagnosis time
