Abstract: The present disclosure is directed to a system and method for reducing ice or condensation that forms on a power component of a wind turbine during a power outage. The method includes determining an ambient temperature near the power component; providing one or more parameters of the power component; determining a down time of the power component for the power outage; determining a wait time for the power component to stay offline as a function of the ambient temperature, the one or more parameters, and the down time of the power component; and, heating the power component for the wait time before supplying power to the power component such that a surface temperature of the power component is raised above the ambient temperature. As such, the method prevents the power component from being energized when condensation or ice may be present.

Abstract: A cooling system for use in cooling an electrical component of a wind turbine is described herein. The cooling system includes a first heat exchange assembly that is coupled to the electrical component. The first heat exchange assembly is configured to transfer heat from the electrical component to a cooling fluid. A fluid distribution assembly is coupled to the first heat exchange assembly for selectively channeling the cooling fluid to the first heat exchange assembly. The fluid distribution assembly is configured to adjust a flowrate of the cooling fluid being channeled to the first heat exchange assembly to adjust a temperature of the component.
