Abstract
An electrical power system connectable to a power grid includes a plurality of electrical power subsystems, each of the plurality of electrical power subsystems including a power converter electrically coupled to a generator having a generator rotor and a generator stator. The electrical power system further includes an intermediate power path extending from each of the plurality of electrical power subsystems for providing power from each of the plurality of electrical power subsystems to the power grid. The electrical power system further includes a zig-zag transformer electrically coupling each of the plurality of intermediate power paths to the power grid, the zig-zag transformer including a primary winding and a plurality of secondary windings, each of the plurality of secondary windings connected to one of the plurality of intermediate power paths, and wherein at least one of the plurality of secondary windings is a zig-zag winding.
