Zusammenfassung: | Wind turbine systems 100 and methods for operating wind turbine systems 100 are provided. In one embodiment, a method includes gating on a dynamic brake switch 184 of a dynamic brake 180 in a wind turbine power converter 130 when an experienced direct current (DC) bus voltage 202 is equal to or greater than a threshold DC bus voltage 204. The method further includes disabling a threshold temperature rating 222 for the dynamic brake switch 184 when the dynamic brake switch 184 is gated on, and gating off the dynamic brake switch 184 when the experienced DC bus voltage 202 is less than the threshold DC bus voltage 204. |
