Abstract: A repair method for a gearbox assembly for a wind turbine is disclosed. The gearbox includes a gearbox housing having an upwind end and a downwind end, a gear assembly configured within the gearbox housing, at least one shaft configured with the gear assembly and extending from the gearbox housing to a generator of the wind turbine, and a sleeve assembly configured with the gearbox housing. Further, the sleeve assembly is removable so as to provide additional space in the gearbox housing during at least one of disassembly or assembly of the gearbox assembly such that the various components can be easily repaired and/or replaced.

Abstract: A power generation system is provided. The system includes a bus, at least two converters, an energy-type energy storage unit (ES), a power-type energy storage unit (PS) and a controller. The ES and the PS are coupled in parallel to the bus through corresponding converters of the at least two converters. The controller is configured to control the ES and the PS through the corresponding converters in at least two conditions during a charging mode and a discharging mode: when a power for the ES and PS is below a power threshold, control the power to flow between the ES and the bus; and when the power is above the power threshold, control a part of the power to flow between the ES and the bus and another part of the power to flow between the PS and the bus. And a method for generating power is also provided.

Abstract: The present subject matter is directed to a wind turbine blade alignment method. A sensor provided on the blade at a blade station with a known twist angle is used to measure an installation angle of the blade station. The installation angle is adjusted if the installation angle measured by the sensor is not equal to the known twist angle. A wind turbine with such a sensor for measuring an installation angle used for blade alignment is also provided.
