Title (EN) METHOD AND APPARATUS FOR ANALYZING WAVEFORM SIGNALS OF A POWER SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR ANALYSER DES SIGNAUX DE FORME D’ONDE D’UN SYSTÈME D’ALIMENTATION
Abstract: front page image
(EN)Method and apparatus for analyzing waveform signals of a power system. A waveform signal obtained from the power system is digitalized and then filtered. One or more segments are identified on the filtered waveform signal and, based on the information content of the identified segments, each of the one or more identified segments are classified as corresponding to a normal or abnormal condition occurred in the power system.
(FR)La présente invention concerne un procédé et un appareil pour analyser des signaux de forme d’onde d’un système d’alimentation. Un signal de forme d’onde obtenu à partir du système d’alimentation est numérisé, puis filtré. Un ou plusieurs segments sont identifiés sur le signal de forme d’onde filtré et, sur la base du contenu des informations des segments identifiés, chaque segment identifié est classé comme correspondant à une condition normale ou anormale s’étant produite dans le système d’alimentation.
