Beschreibung
Zusammenfassung:	A control method and associated system provide for thermal management of cables within a structure of a wind turbine. An airflow is established through the structure, the airflow moving along and around the cables within the structure to remove heat generated in the cables via heat transfer from a core of the cables through a surrounding insulation layer of the cables. Ambient temperature and a volumetric flow rate of the airflow adjacent the cables is measure. Based on the flow rate and the ambient temperature, a threshold current capacity limit for the cables is determined and used as a control factor for increasing power production of the wind turbine within thermal limits of the cables.
