Abstract
(DE)
Stromrichter einer Hochspannungs-Gleichstromübertragungsanlage oder anderer Stromrichteranlagen erfordern häufig Regelkreise für mehrere Regelgrössen. Nur ein Regelkreis bestimmt dabei den Steuerwinkel, während die anderen Regelkreise in Bereitschaft gehalten werden müssen, um diesen Regelkreis bei schnellen Änderungen des Betriebszustandes abzulösen. Erfindungsgemäss werden zwar die Regeldifferenzen aller Regelgrössen erfasst und für jede Regelgrösse die Reglerparameter einer vorprogrammierten allgemeinen Regelstruktur bereitgestellt. Jedoch ist nur ein Regler mit der vorprogrammierten allgemeinen Regelstruktur vorhanden. Dieser Regler ist stets im Eingriff, greift aber nur auf den Minimalwert oder Maximalwert der Regeldifferenzen ein und benutzt jeweils die Reglerparameter, die zu dem jeweils aktivierten Regelkreis gehören.

Power converters of a high-voltage d.c. transmission installation or other converter installations often require regulating circuits for several parameters. Here only one regulating circuit determines the control angle while the others must be kept ready to back up this circuit during rapid changes in the operating condition. According to the invention, the adjustment differences of all parameters are indeed covered and the adjustment parameters of a preprogrammed general control structure are prepared for each adjustment value, but there is only one regulator with the preprogrammed general control structure. This regulator is always engaged but acquires only the minium or maximum of the control differences and uses the control parameters allocated to the regulating circuit concerned at the time.
(FR)
Les convertisseurs d'une installation haute tension de transmission en courant continu ou d'autres installations de convertisseurs nécessitent fréquemment des circuits de réglage pour plusieurs grandeurs de réglage. Un seul circuit de réglage détermine alors l'angle de retard à la commande, cependant que les autres circuits de réglage doivent être maintenus en attente, afin de relayer ce circuit de réglage lors de variations rapides de l'état de fonctionnement. Conformément à l'invention, les différences de réglage de toutes les grandeurs de réglage sont saisies et, pour chaque grandeur de réglage, les paramètres de réglage d'une structure de réglage pré-programmée de façon générale sont disponibles. Il n'existe toutefois qu'un seul régulateur à structure de régulation pré-programmée de façon générale. Ce régulateur est constamment opérationnel, mais n'agit qu'à une valeur minimale ou maximale des différences de réglage, et utilise à chaque fois les paramètres de réglage appartenant au circuit de réglage activé respectif.
