Title (EN) TIME DELAY COMPENSATION IN POWER SYSTEM CONTROL
(FR) COMPENSATION DES RETARDS DANS LA COMMANDE DES SYSTÈMES ÉLECTRIQUES
Abstract: front page image
(EN)The present invention is concerned with the compensation of time delays in remote feedback signals in power system control. A method is describedwhich comprises converting the time delay into a phase shift and calculating four compensation angles from the phase shift. Theoptimal compensation angleis determined and applied to the remote feedback signals. A technique of equipping a controller with a global clock is also disclosed.
(FR)La présente invention concerne la compensation des retards qui se produisent dans les signaux de retour distants pour commander des systèmes électriques. Un procédé ci-décrit consiste à convertir le retard en déphasage et à utiliser ce déphasage pour calculer quatre angles de compensation. L’angle de compensation optimal est déterminé, puis appliqué auxdits signaux de retour distants. Une technique consistant à équiper un contrôleur d’une horloge globale est également décrite.
