Claim 0:
1. A power system comprising:
a turbine assembly comprising a turbine and a turbine shaft;
a generator assembly comprising a generator and a generator shaft, the generator shaft extending from a first end to a second end;
an inertia assembly comprising a flywheel shaft and a flywheel coupled to said flywheel shaft, said flywheel shaft coupled to said generator shaft at said second end; and
a first clutch assembly for coupling said turbine shaft to said generator shaft at said first end, said first clutch assembly being transitionable between a closed state, in which said turbine shaft is coupled to said generator shaft, and an open state, in which said turbine shaft is decoupled from said generator shaft, wherein said power system is operable in a power generation mode when said first clutch assembly is in the closed state and a synchronous condenser mode when said first clutch assembly is in the open state; and
a second clutch assembly for coupling said flywheel shaft to said generator shaft, said second clutch assembly enabling operation of said power system in a standard inertia synchronous condenser mode and a high inertia synchronous condenser mode, wherein said power system has a first inertia constant when operating in the standard inertia synchronous condenser mode and a second inertia constant when operating in the high inertia synchronous condenser mode, the second inertia constant being greater than the first inertia constant by at least a factor of 2.5.
