Abstract: A power generation system comprising a plurality of power generation units; a plurality of energy storage units; a plurality of switch units for connecting or disconnecting the power generation units and the energy storage units; and a controller for controlling the switch units to disconnect one or more idle power generation units from their corresponding energy storage units when the idle power generation units stop operating and to connect the disconnected energy storage unit to one operating power generation unit of the plurality of power generation units based on states-of-charge of the energy storage units. The power generation system may make best use of the energy storage units.

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.

Abstract: The invention relates to a method for performing up-tower maintenance on a gearbox bearing of a wind turbine. In particular, a method for performing up-tower maintenance on a gearbox of a wind turbine is disclosed. The gearbox has at least one bearing with an outer race and an inner race that rotates with respect to the outer race. The method includes forming a through-hole in a front cover of the gearbox, the front cover being stationary with respect to an axis of rotation of the bearing. The method also includes forming a recess in the outer race of the bearing. Further, the method includes inserting a connecting member through the through-hole and the recess so as to prevent movement of the outer race of the bearing with respect to a torque arm of the gearbox.

Abstract: A gearbox assembly includes a gearbox housing and a planetary gear system configured within the gearbox housing. The planetary gear system includes a plurality of planet gears, at least one sun gear, at least one ring gear, at least one planetary carrier operatively coupled with the plurality of planet gears, and a plurality of pin shafts. Each of the plurality of planet gears are arranged so as to rotate around one of the plurality of pin shafts. Further, the plurality of planet gears are engaged with the ring gear and configured to rotate about the sun gear. The gearbox assembly also includes a first lubricant path defined from a first location to a second location through the at least one planetary carrier. Moreover, the first lubricant path is located outside of the plurality of pin shafts.

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.
