International Classification:

F03D 9/00
H02P 9/00

US Classification:

290 44, 322 44

Abstract:

An integrated fault and personnel protection system and method for a multi-thread converter in a wind turbine power system is provided. The structure and method provide for system optimization, as well as, arc flash protection. Fault sensing with means of removing power applied to the converter minimizes the energy available to produce an arc flash event. Sensing and disconnects devices for the protections are provided close to the source of energy to protect more of the system. Converter controls detect, identify and isolate faults selecting the best combinations of the novel specific fault isolation devices. Components are distributed into separate physical to enhance protection.

International Classification:

F03D 11/00

US Classification:

290 1 B

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.

International Classification:

F03D 7/04
F03D 7/02

Abstract:

A system and method are provided for controlling a wind turbine to protect the wind turbine from anomalous operations. Accordingly, in response to receiving data indicative of an anomalous operational event of the wind turbine, the controller initiates an enhanced braking mode for the wind turbine. The enhanced braking mode is characterized by operating the generator at a torque setpoint that generates maximum available torque for a given set of operating conditions. Additionally, the torque setpoint is in excess of a nominal torque limit for the generator.

International Classification:

F03D 80/00

Abstract:

A system for adjusting environmental operating conditions associated with heat generating components located within a tower of a wind turbine may include a heat generating component located within an interior of the tower, a sensor configured to monitor a heat exchange parameter associated with the wind turbine and a split heat exchange system provided relative to the tower. The split heat exchange system may include a first heat exchanger located within the interior of the tower and a second heat exchanger located exterior to the tower. The system may also include a controller communicatively coupled to the sensor and the split heat exchange system. The controller may be configured to control the operation of the split heat exchange system based at least in part on the monitored heat exchange parameter to adjust an environmental operating condition associated with the heat generating component.
