Fault detection in transmission networks of power systems
International Journal of Electrical Power & Energy Systems, 2011 Abstract An online fault detection scheme for a sample power system is introduced in this paper. The detection approach is based on the use of a variable structure system called “sliding mode observer”, where information contained in the output measurements is utilized to detect the onset of faults in the transmission network of the sample power ...

Performance evaluation of machine learning for fault selection in power transmission lines [PDF]
Knowledge and Information Systems, 2022 AbstractLearning methods have been increasingly used in power engineering to perform various tasks. In this paper, a fault selection procedure in double-circuit transmission lines employing different learning methods is accordingly proposed. In the proposed procedure, the discrete Fourier transform (DFT) is used to pre-process raw data from the ...
