Abstract
A cross current compensation system for controlling reactive currents in a generator is provided. A control system for receives voltage feedback from a first generator of a plurality of generators and cross current feedback from at least a second generator of the plurality of generators. The control system determines a phase angle based on the voltage feedback from the first generator and cross current feedback from the at least a second generator. The control system determines a compensation signal corresponding to the phase angle and cross current feedback. The control system modifying a generator excitation signal for the first generator based on the respective compensation signal and a bi-linear transformation technique.
