Power generation system including an apparatus for attaching a generator stator core to frame support and associated methods

DETAILED DESCRIPTION In view of the foregoing, the present invention advantageously provides a high voltage power generation system including an apparatus for attaching a generator stator core to a frame support and methods of stabilizing a power generation system and reducing vibration and eliminating lateral movement of a generator stator core during operation that are efficient and cost effective.
The present invention also advantageously provides an apparatus and methods for protecting a power generation system from the forces associated with transient faults and compensating for deformations that result in radial and tangential forces that are encountered when the generator stator core experiences an "oval mode" condition.
More particularly, the present invention provides a power generation system that includes a stator core frame support member having a lower inner surface portion and a lower outer surface portion.
The lower inner surface portion preferably has a substantially semi-annular shape, and the lower outer surface portion is positioned to contact a support surface.
The system also includes a generator stator core having a substantially annular shape.
The generator stator core includes a plurality of keybars positioned spaced-apart and extending along outer peripheral portions of the generator stator core.
The generator stator core is positioned to overlie the lower inner surface portion of the stator core frame support member and has a lower end portion positioned spaced-apart from and not in contact with bottom portions of the lower inner surface of the stator core frame support member.
The upper end portion of the generator stator core is also positioned spaced-apart from and not in contact with the stator core frame support.
The system further includes a core supporter connected to the stator core frame support member.
The core supporter is positioned to contact a plurality of keybars that are positioned along outer side peripheries of the generator stator core.
The core supporter preferably has first and second core connecting means for attaching the stator core frame support member to the generator stator core
