An electric power distribution system for an aircraft is provided, which includes an engine gearbox, a power distribution center, two or more three-phase synchronous electric power generators, a neutral current transformer per generator, a single set of power feeder wires, and a single generator control unit (GCU). The generators are connected in parallel with each other, and connected with the power distribution center by the same set of power feeder wires. The GCU is electrically coupled with each generator to feed the generator with an excitation field current, and with each neutral current transformer to sense an instantaneous neutral-current value. The GCU is adapted to perform a generator voltage regulation loop based on a desired voltage value and the at least two sensed instantaneous neutral-current values by individually modifying the excitation field current of each generator.
