Abstract

LA PRESENTE INVENTION A POUR BUT D'ELIMINER LES FLUCTUATIONS DE TENSION RAPIDES ET A CARACTERE ALEATOIRE, SENSIBLES A L'OEIL HUMAIN, INTRODUITES DANS UN RESEAU DE DISTRIBUTION D'ENERGIE PAR LA MODIFICATION DE LA COMPOSANTE REACTIVE DU COURANT. SELON L'INVENTION, LE CIRCUIT DE COMMANDE INCLUT UNE CHAINE COMPORTANT UN FILTRE ACTIF 13 IMPRIMANT AVEC UN GAIN SENSIBLEMENT UNITAIRE UNE AVANCE DE PHASE EGALE AU RETARD DE PHASE INTRODUIT PAR L'ENSEMBLE CONSTITUE PAR LE COMPENSATEUR STATIQUE ET UN CAPTEUR 11 POUR DES FREQUENCES INFERIEURES A 25HERTZ. LES SIGNAUX ISSUS DE CETTE CHAINE SONT APPLIQUES A L'ENTREE D'UN GENERATEUR 8 DES IMPULSIONS DE COMMANDE DES THYRISTORS DU COMPENSATEUR. APPLICATION: FOUR A ARC.
