1. WO/2015/099204 HORIZONTAL SHAFT WIND POWER GENERATORWO02.07.2015
F03D 1/00
PCT/KR2013/010933SAM WON TECH CO.,LTDLEE, Taek Woo
The present invention relates to a horizontal shaft wind power generator comprising: a power generation unit which is positioned at a given height from the ground; a rotational blade unit which is positioned on one side of the power generation unit and includes a plurality of blades; and a reinforcement support unit which is positioned between the rotational blade unit and the power generation unit, wherein the reinforcement support unit includes a reinforcement support unit housing, the reinforcement support unit housing including a bearing unit and a coupler unit. Since a horizontal shaft is dualized into a first horizontal shaft connected to the rotational blade unit and a second horizontal shaft connected to the power generation unit, even if the size of the blades increases and excessive force is applied to the first horizontal shaft, the force is distributed to the reinforcement support unit including the first horizontal shaft so that excessive force is not applied to the second horizontal shaft. Therefore, the present invention can prevent malfunctions of the power generator caused by an increase in the size of the blades.

2. WO/2015/097795 WIND-SPEED EVALUATION METHOD, POWER GENERATION AMOUNT ESTIMATION METHOD, OUTPUT AND VOLTAGE ESTIMATION METHOD, PLACEMENT METHOD FOR WIND POWER GENERATOR, AND WIND-SPEED EVALUATION DEVICEWO02.07.2015
F03D 7/02
PCT/JP2013/084745HITACHI, LTD.IKEDA Masaki
The objective of the invention is to provide a more reliable power generation amount estimation method and power generation amount estimation apparatus for a wind farm by improving the accuracy of evaluation of wind speed for wind power generation systems. This method for evaluating the wind speed of a wake from a wind power generator comprises the steps of measuring wind speed upstream of a wind power generator installed on land or sea, measuring the wind speed of the wake from the wind power generator with a wind-speed measurement means installed downstream of the wind power generator, and calculating the wind speed of a first wake from the wind power generator using at least one parameter among wind speed upstream of the wind power generator, radius of a wind turbine rotor of the wind power generator, distance between the wind power generator and the wind-speed measurement means, thrust coefficient of the wind power generator, and wake attenuation coefficient for the wake from the wind power generator. This method is characterized by calculating the wind speed of a second wake from the wind power generator from a correlation between the wind speed of the wake from the wind power generator measured by the wind-speed measurement means and the wind speed of the first wake from the wind power generator calculated using the parameter(s).

 A divided holder has a pair of annular parts in which a plurality of concavities are formed in the inner peripheries at intervals in the circumferential direction, and a column part having column ends that fit in the concavities in both axial sides, reactive force acting on the column part the other way in the circumferential direction. Between the concavities and the outer peripheral surface of an inner ring, the concavities have wedge surfaces for configuring wedge-shaped spaces that narrow in the radial direction towards the other way in the circumferential direction. The column ends have wedge shapes of which the radial dimensions narrow towards the other side in the circumferential direction, and also have radially inner surfaces that come in contact with the outer peripheral surface of the inner ring and radially outer surfaces in contact with the wedge surfaces.

F03D 7/02
PCT/US2014/069288GOOGLE INC.VANDER LIND, Damon
Methods and systems described herein relate to power generation control for an aerial vehicle of an air wind turbine (AWT). More specifically, the methods described herein relate to balancing power generation or preventing a component of the aerial vehicle using rotor speed control. An example method may include operating an aerial vehicle in a crosswind- flight mode to generate power. The aerial vehicle may include a rotor configured to help generate the power. While the aerial vehicle is in the crosswind-flight mode the method may include comparing a power output level of the aerial vehicle to a power threshold and, based on the comparison, adjusting operation of the rotor in a manner that generates an optimal amount of power or minimizes overheating of the aerial vehicle.

A method of making an elongate wind turbine blade is described. The wind turbine blade extends longitudinally between a root end and a tip end in a spanwise direction, and the method comprises: (a) providing an elongate mould tool (20) extending longitudinally in a spanwise direction; (b) arranging an elongate spar structure (40) in the mould tool, the spar structure (40) extending longitudinally in the spanwise direction; (c) arranging core material (24) adjacent to the spar structure (40); (d) providing resin-permeable material (114) between the spar structure (40) and the core material (24); and (e) administering resin into the mould during a resin infusion process. The resin-permeable material (114) restricts the flow of resin between the spar structure (40) and the core material (24) in the spanwise direction and thereby substantially prevents lock-offs from forming during the infusion process.
