A system for stiffening and pre-stressing a generator frame in a wind turbine is provided. The system includes a plurality of stress-inducing members configured for imparting a predetermined amount of stress on the generator frame. Each of the plurality of stress-inducing members has a length, a first end, and a second end and the length of each of said plurality of stress-inducing members is selectively adjustable. A coupling plate is configured for coupling the second ends of at least some of the plurality of stress-inducing members together. A plurality of brackets are coupled to the generator frame and configured to couple the first ends of the plurality of stress-inducing members to the generator frame.
