In a method of series compensating rotating electric alternating current machines (2) connected, directly or via a static current converter (28), to a three-phase distribution or transmission network (6), wherein the stator winding of the alternating current machine is Y-connected, a capacitive circuit (14) for the fundamental frequency of the voltage is connected in each phase between the down side of the winding and the earth point (20) of the distribution or transmission network (6). A device for such series compensation comprises a capacitive circuit (14) for the fundamental frequency of the voltage, connected between the down side of the winding and the earth point (20) of the distribution or transmission network (6).

Cette invention se rapporte à un procédé de compensation en série de machines électriques tournantes à courant alternatif (2) connectées directement ou via un convertisseur de courant statique (28), à un réseau de distribution ou de transmission triphasé (6), procédé dans lequel l'enroulement du stator de la machine à courant alternatif présente une connexion en Y, et un circuit capacitif (14) pour la fréquence fondamentale de la tension est connecté dans chaque phase entre le côté bas de l'enroulement et le point de mise à la terre (20) du réseau de distribution ou de transmission (6). Un dispositif servant à réaliser une telle compensation en série comprend un circuit capacitif (14) pour la fréquence fondamentale de la tension, connecté entre le côté bas de l'enroulement et le point de mise à la terre (20) du réseau de distribution ou de transmission (6).
