SVD-BASED AUTOMATIC IDENTIFICATION OF AXIS TRACK OF HYDROPOWER GENERATING SETS

Ni Chuankun, Zhou Jianzhong (Huazhong University of Science and Technology, Wuhan 430074, China)  
The axis track is an important characteristic to be used to diagnose the unit condition in the condition-based maintenance system of hydropower generating sets. The automatic identification of axis track of the generating sets is studied by use of the nearest-neighbor classifier, in combination with the method of SVD, the characteristic value of which is used as feature vector. The principle of the method is introduced in detail, and simulations of automatic identification for some typical axis tracks are given. The results prove the effectiveness, simplicity and feasibility of the method.
