A steam turbine-generator vibration fault diagnosis method based on rough set
Jian Ping Ou, Caixin Sun, Bi Weimin, Bide Zhang, Liao Ruijin · 2003
According to turbine-generator vibration characteristic spectrum, a discretized generator fault attribute decision table and condition. attribute set reduction method based on rough set theory are presented in this paper, though the key character which influences classifying is picked up. BP network input dimension is reduced and training time is saved. Experiment shows that the result is effective.
