Claim:
1. 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, the method comprising: replacing the first turbine with a motor, the motor coupled to the first generator and operable to drive the first generator; 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; powering the motor to drive the first generator and to synchronize the first generator to the grid; providing electrical power to the second generator from the first generator to power the second generator and synchronize the second generator to the grid; and varying an excitation voltage for one of the first generator and the second generator to vary the reactive power output of the first generator and the second generator.
