Abstract
A power generation system (10) including an apparatus for attaching a generator stator core (20) to a frame support (30) and associated methods are provided. The system (10) preferably includes a stator core frame support member (30) and a generator stator core (20) including a plurality of keybars (22) positioned spaced-apart and extending along outer peripheral portions of the generator stator core (20). The generator stator core (20) is positioned to overlie the stator core frame support member (30). The system (10) further includes a core supporter (40) connected to the stator core frame support member (30) and positioned to contact the generator stator core (20). The core supporter (40) includes first (43) and second (44) core connectors (42) for low tuning the natural frequency of a generator stator core (20) and for stabilizing the power generation system during operation. The method of stabilizing the power generation system (10) during operation includes attaching first (43) and second (44) core supporters (42) along a stator core frame support (30) and positioning the generator stator core (20) to overlie the stator core frame support (30). The method also includes connec…
