Title
(EN) PROCESS FOR STABILIZING AN OSCILLATORY ELECTRICAL SUPPLY NETWORK
(FR) PROCEDE DE STABILISATION D'UN RESEAU D'ALIMENTATION ELECTRIQUE SOUMIS A DES OSCILLATIONS
Abstract
(EN)
To eliminate mains fluctuations, at least one signal dependent on the mains frequency is recorded and stored, and a fluctuation is detected by comparing consecutively stored signals. After detection of a fluctuation, at least one parameter of the regulator which determines the voltage or the frequency is varied in such a way that the fluctuation is attenuated. The adjustment time of pronounced mains fluctuations is increased by the use of a PI output regulator (4).
(FR)
Pour supprimer les oscillations d'un réseau, il est proposé de surveiller, d'identifier et de mettre en mémoire au moins un signal dépendant de la fréquence du réseau, de comparer entre eux des signaux successifs mis en mémoire afin de déceler une oscillation et, après avoir identifié une oscillation, de modifier au moins un paramètre d'un régulateur déterminant la puissance, la tension ou la fréquence, de manière à amortir l'oscillation. L'utilisation d'un régulateur de puissance PI (4) augmente le temps de compensation du régulateur lors de l'apparition d'oscillations dans le réseau.
