High impedance fault has always been difficult for distribution network fault identification due to its unobvious fault signature and difficult detection. This paper decomposed the transient signal in multi-scale by utilizing the good localization performance of the wavelet in both time domain and frequency domain, reconstructed the wavelet coefficients under each scale, took the wavelet reconstruction...
This paper presents a pattern-based information-processing approach, called characteristics recognition (CR), for on-line supervision of knowledge-based control systems. This approach provides a method for the analysis and automatic extraction of different types of process behaviour features during operation without a precise description of the process model. By combining the use of symbolic manipulation,...
