Abstract
This paper presents an algorithm used in the analysis of simultaneous fault characteristics. The system under investigations is the 500-kV transmission network in Thailand. The analysis is performed using PSCAD/EMTDC and MATLAB/Simulink. Wavelet transform is used in order to detect high frequency components of the fault current signals. The characteristics of the fault current with various fault inception angles, fault locations and faulty phases are observed. It is found that the technique proposed in this paper gives satisfactory results in the simultaneous fault classification. © 2008 IEEE.
