Abstract
A power generation system that includes a prime mover configured to generate mechanical energy. The power generation system also includes a power generator configured for generating electrical power from the mechanical energy received from the prime mover. The power generation system further includes a fault ride-through switch electrically coupled in series between the power generator and a power grid. The fault ride-through switch includes a first branch configured to carry the electrical power during normal operating conditions and includes an LC resonance circuit. The fault ride-through switch also includes a multiphase transformer configured for providing voltage phases of different polarities to the LC resonance circuit. The fault ride-through switch further includes a second branch coupled in parallel with the first branch and including a resistive element and an inductive element electrically coupled in series wherein the resistive element configured to absorb the electrical power during fault conditions.
