摘要
Experimental platform is used to simulate typical faults of turbine. Based on the frequency domain feature, energy eigenvector of frequency domain is presented using harmonic wavelet packet analysis method. Finally, the fault states are recognized using improved neural network, and the simulations show that it made a good performance with the method.
