Harmonics are usually analyzed through Fourier transform or wavelet transform, both of which have their shortcomings. Wavelet neural-network is a new algorithm that combines wavelet analysis with neural-network, suitable for processing signals with time-varying frequency domain characters. To analyze the third and fifth harmonics, a wavelet network structure was constructed, training algorithm described...
It is important to make sure that the High Voltage Circuit Breaker (HVCB) have reliable performance in power system. So it is important to have a knowledge of when the HVCB need maintenance. The paper would use the data mining techniques to predict when to maintain HVCB. As the data is imbalanced, one class is less than the other, the paper would like to introduce an imbalanced learning processing...
