Abstract: A method for repairing an electric generator having a rotor that rotates about a vertical axis, the rotor including a spider having a number of spider arms extending radially away from the axis, and a rim surrounding the spider. The weight of the rim is normally carried at least in part by rim support ledges of the spider arms. The method for repair includes supporting the rim from the top of the spider and thereby relieving some or all of the weight of the rim being supported by the rim support ledges.

Abstract: A method of controlling reactive power in a power generation system that includes a grid and a cross compound turbine generator system having a first turbine arranged to drive a first generator and a second turbine arranged to drive a second generator includes replacing the first turbine with a motor, the motor coupled to the first generator and operable to drive the first generator. The method also includes decoupling the second turbine and the second generator to allow the second generator to rotate separate from the second turbine, connecting an electrical output of the first generator to the second generator, and powering the motor to drive the first generator and to synchronize the first generator to the grid.
