1. WO/2015/040730 OFFSHORE WIND POWER GENERATOR DEVICE AND OIL-IMMERSED TRANSFORMER USED IN SAMEWO26.03.2015
F03D 11/00
PCT/JP2013/075427HITACHI INDUSTRIAL EQUIPMENT SYSTEMS CO., LTD.MASHIMA Yasushi
In offshore wind power generator devices, with the objectives of safety and the suppression of loss during power transmission, there is the requirement of installing a transformer within the offshore wind power generator devices. When doing so, an increase in cooling performance of oil-immersed transformers used in the offshore wind power generator devices is called for. To solve said problem, an oil-immersed transformer housing in a tank a core, a coil, and insulating oil that cools and insulates the core and coil is installed below the sea surface within a wind power generator device, and the structure is such that the tank is immersed in liquid. As a result, greater compactness of the oil-immersed transformer and the offshore wind power generator device is possible by means of increasing the cooling performance of the oil-immersed transformer used in the offshore wind power generator device.

2. WO/2015/040360 HYDRAULIC TRANSMISSIONWO26.03.2015
F04B 1/053
PCT/GB2014/050566ARTEMIS INTELLIGENT POWER LIMITEDCALDWELL, Niall
A hydraulic transmission comprising a variable displacement pump and motor, at least one of which has cylinders having valves which are controllable on each cycle of cylinder working volume to determine the net displacement of working fluid by the cylinder. The transmission has a valve control module which determines a displacement of the pump and the motor by specifying a displacement demand. The pump and/or motor valve control module determine the frequency of intensity peaks in the frequency spectrum of the pattern of cylinders carrying out active and inactive cycles of cylinder working volume using a first procedure and, if these will fall within disallowed frequency bands including the resonant frequency of components with which the transmission is in mechanical communication, the displacement demand, or another input, is periodically modified to supress generation of those frequencies. The hydraulic transmission is useful for example in a wind turbine generator, or a vehicle.

F03D 9/02
PCT/CN2014/085450HUANG, JieHUANG, Jie
Disclosed are an apparatus for replenishing flywheel battery (3) energy using wind power during travel of a bicycle, and a method of use. An inner drive device is added to a vacuum box (33) of a flywheel battery (3), and comprises a magnetomotive wheel (51), a centrifugal mechanism (53) and a concave friction wheel (54); and an outer drive device is provided outside the vacuum box (33) and comprises an impeller (41), a speed increaser (42) and a driving sleeve (43) containing a magnet (431). One end of a flywheel (31) of the flywheel battery (3) is connected to a convex friction wheel (32), and the convex friction wheel (32) is connected to the concave friction wheel (54) intermittently. A method of use involves: during travel of a bicycle, the impeller (41) rotates because of the wind, making the speed increaser (42) drive the rotation of the driving sleeve (43), the magnet (431) in the driving sleeve (43) couples with the magnetomotive wheel (51) by means of a magnetic field, driving the rotation together of the magnetmotive wheel (51), the centrifugal mechanism (53) and the concave friction wheel (54), thereby driving the rotation of the flywheel (31) to store energy. The benefit is: in the case of no power source, the bicycle can be used to input kinetic energy into the flywheel battery. When the impeller rotates at a certain rotating speed, a drive mechanism automatically approaches the flywheel to provide kinetic energy. After the impeller stops, the drive mechanism automatically separates from the flywheel to prevent energy wastage.

The invention relates to a method of controlling a wind turbine, the wind turbine comprising wind turbine blades attached to a rotor hub and a control system for pitching the blades relative to the hub. The method comprises providing wake sectors assigned to different wind directions and providing a normal pitch schedule to control an output parameter of the wind turbine (e.g. power, rotational speed), comprising pitch reference values as a function of the wind speed and at least one of the parameters of thrust coefficient Ct and axial induction factor a. Further, is provided a modified pitch schedule to control a modified output parameter of the wind turbine, comprising pitch reference values in dependence of the wind speed and at least one modified parameter of the thrust coefficient and/or the axial induction factor. Upon receiving indications of a wind speed and a wind direction at the wind turbine is determined a pitch reference value for the wind turbine blades according to the normal pitch schedule if the wind direction falls outside the wake sector and otherwise according to the modified pitch schedule. The wind turbine is then controlled according to the pitch reference value. The invention further relates to a method of controlling the wind turbines in a wind park, wherein each wind turbine in the park is controlled locally according to the above mentioned control method.
