Un armazón (144) de generador de turbina eólica que incluye un sistema (200) de refuerzo, comprendiendo dicho sistema de refuerzo: una pluralidad de elementos (210) inductores de tensión configurados para ejercer una cantidad predeterminada de tensión sobre el armazón de generador, teniendo cada uno de dicha pluralidad de elementos inductores de tensión un primer extremo (214) y un segundo extremo (212), estando dicho primer extremo configurado para acoplarse al armazón de generador; caracterizado porque dicho sistema de refuerzo comprende además una placa (220) de acoplamiento configurada para acoplar entre sí dichos segundos extremos de dos o más de dicha pluralidad de elementos inductores de tensión; en el que la longitud de cada uno de dicha pluralidad de elementos (210) inductores de tensión es ajustable. A stiffening system (200) for use in a generator frame (144) of a wind turbine (100) is provided. The stiffening system includes a plurality of stress-inducing members (210) configured for imparting a predetermined amount of stress on the generator frame, each of the plurality of stress-inducing members having a first end (214) and a second end (212), the first end configured to be coupled to the generator frame, each of the plurality of stress-inducing members having a second end, and a coupling plate (220) configured for coupling the second ends of two or more of the plurality of stress-inducing members together.
