Slowly rotating electrical machines, for example, ring generators, as used in wind energy plants produced by the firm Enercon of the types E-33, E-40, E-12 and E-66, require a high excitation power. The required excitation power rises with the number of poles, with increasing airgap and with the size of the reactive power. The aim of the invention is to improve the efficiency of directly-driven generators, as described above and to avoid the disadvantages described above. Said aim is achieved, whereby the generator of a slowly rotating synchronous generator (ring generator) for a wind energy plant, comprises a rotor and a stator, surrounding the rotor. The stator has at least one three-phase winding, injected with a capacitive current and/or part of the excitation power is generated by the stator.

Les machines électriques tournant lentement, par exemple les générateurs annulaires, utilisés dans les éoliennes de la société Enercon du type E-33, E-40, E-12 et E-66, requièrent une grande puissance d'excitation. Ces besoins en puissance d'excitation augmentent avec le nombre de pôles, la dimension de l'entrefer et la valeur de la puissance apparente. L'invention vise à accroître le rendement de générateurs du type mentionné, à entraînement direct, et à éviter les inconvénients décrits précédemment. A cet effet, on utilise un générateur synchrone tournant lentement (générateur annulaire), destiné à une éolienne, présentant un rotor et un stator entourant ce dernier. Le stator présente au moins un enroulement triphasé auquel est appliqué un courant capacitif, et/ou une partie de la puissance d'excitation du générateur est produite par le stator.
