Abstract:
(EN) Disclosed are a method and an arrangement for testing the working order of a DC link (60) in a multi-voltage power network (50) comprising a d.c-d.c. converter (56). According to said method a fixed current is set and supplied to the DC link (60) and a voltage applied to the DC link (60) is measured at temporally sequential sampling points, a capacity (64) of the DC link (60) being calculated from the measured voltage values, taking into consideration the intervals between the sampling points.
(FR) L'invention concerne un procédé et un système de contrôle de la fonctionnalité d'un circuit intermédiaire (60) dans un réseau multi-tensions (50) qui comprend un convertisseur de tension continu-continu (56). Le procédé consiste à régler un courant fixe qui est appliqué au circuit intermédiaire (60) et à mesurer une tension aux bornes du circuit intermédiaire (60) à des temps de scrutation successifs dans le temps. A partir des valeurs de tension mesurées, on calcule une capacité (64) du circuit intermédiaire (60) en tenant compte des durées qui séparent les temps de scrutation.
(DE) Es werden ein Verfahren und eine Anordnung zum Überprüfen der Funktionsfähigkeit eines Zweischenkreises (60) in einem Mehrspannungsnetz (50), das einen Gleichspannungswandler (56) umfasst, vorgestellt. Bei dem Verfahren wird ein fester Strom eingestellt, mit dem der Zwischenkreis (60) beaufschlagt wird, und eine Spannung, die am Zwischenkreis (60) anliegt, an zeitlich aufeinanderfolgenden Abtastpunkten gemessen, wobei aus den gemessenen Spannungswerten unter Berücksichtigung von Zeitabständen zwischen den Abtastpunkten eine Kapazität (64) des Zwischenkreises (60) berechnet wird.
