Abstract
Wind turbine systems and methods for operating wind turbine systems are provided. In one embodiment, a method includes gating on a dynamic brake switch of a dynamic brake in a wind turbine power converter when an experienced direct current (DC) bus voltage is equal to or greater than a threshold DC bus voltage. The method further includes disabling a threshold temperature rating for the dynamic brake switch when the dynamic brake switch is gated on, and gating off the dynamic brake switch when the experienced DC bus voltage is less than the threshold DC bus voltage.
