Abstract
Ein Differenzialgetriebe (4) für eine Energiegewinnungsanlage, insbesondere für eine Windkraftanlage, weist drei An- bzw. Abtriebe auf, wobei ein erster Antrieb mit einer Antriebswelle (2) der Energiegewinnungsanlage, ein Abtrieb mit einem mit einem Netz (9) verbindbaren Generator (13) und ein zweiter Antrieb mit einer elektrischen Maschine (14, 8) als Differenzial-Antrieb (14) verbunden ist. An die elektrische Maschine (14, 18) sind wenigstens zwei maschinenseitige Frequenzumrichter-Endstufen (22) angeschlossen. Damit kann die elektrische Maschine (14, 18) eine Überdrehzahl des zweiten Antriebs bei Ausfall einer maschinenseitigen Frequenzumrichter-Endstufe (22) durch elektrisches Bremsen mit Hilfe wenigstens einer weiteren maschinenseitigen Frequenzumrichter-Endstufe (22) verhindern.
