Title
(DE) EREIGNISÜBERWACHUNG BEI EINEM STROMRICHTER
(EN) MONITORING AN EVENT IN A POWER CONVERTER
(FR) SURVEILLANCE D'UN ÉVÉNEMENT DANS UN CONVERTISSEUR DE PUISSANCE
Abstract
(DE) Bei einem Verfahren zum Erzeugen einer Ereignisüberwachung bei einem Stromrichter, werden Protokolldaten nach einem Start des Stromrichters verwendet, wobei die Protokolldaten für eine Zeitperiode nach dem Start keinen Fehler zeigen, wobei die Zeitperiode bestimmbar ist. Meldungen werden Quellen für Fehler zugeordnet, wobei für eine Zuordnung eine Wahrscheinlichkeit errechnet wird.
(EN) The invention relates to a method for monitoring an event in a power converter. Record data is used after starting the power converter, wherein the record data does not indicate an error for a period of time after the power converter is started, and the period of time can be determined. Messages are assigned to error sources, and a degree of probability is calculated for an assigning process.
(FR) L'invention concerne un procédé de surveillance d'un événement dans un convertisseur de puissance. Des données d'enregistrement sont utilisées après le démarrage du convertisseur de puissance, les données d'enregistrement n'indiquant pas une erreur pendant une période de temps après le démarrage du convertisseur de puissance, et la période de temps pouvant être déterminée. Des messages sont attribués à des sources d'erreur, et un degré de probabilité est calculé pour un processus d'attribution.
