Title (EN) FAULT DETECTION IN DUAL MICROPROCESSOR ELECTRONIC TRIP UNIT
(FR) DÉTECTION DE DÉFAUT DANS UNE UNITÉ DE DÉCLENCHEMENT ÉLECTRONIQUE
Abstract:
(EN) The invention relates to a fault detection method and system in an Electronic Trip Unit (ETU). An ETU includes a Protection Function (PF) and a Metering Function (MF), each of the PF and MF measuring in parallel the same one or more power line parameters. A comparator compares the first measurement and the second measurement and outputs a fault signal when a disagreement is detected with a given level of accuracy between the first measurement and the second measurement. At least one further comparator may be used that compares the first measurement and the second measurement, and a voter circuit that collects signals resulting from each said comparing and detects a fault when at least one fault signal exists among said collected signals.
(FR) L'invention porte sur un procédé et un système de détection de défaut dans une unité de déclenchement électronique (ETU). Une ETU inclut une fonction de protection (PF) et une fonction de mesure (MF), la PF et la MF mesurant chacune en parallèle un ou plusieurs paramètre(s) identique(s) de ligne électrique. Un comparateur compare la première mesure et la seconde mesure et émet un signal de défaut quand un désaccord est détecté avec un niveau de précision donné entre la première mesure et la seconde mesure. Au moins un autre comparateur qui compare la première mesure et la seconde mesure peut être utilisé, ainsi qu'un circuit votant qui collecte les signaux résultant de chacune desdites comparaisons et qui détecte un défaut quand au moins un signal de défaut existe parmi lesdits signaux collectés.
