Abstract:
A wind turbine generator (10) includes a tower (12), a nacelle (14) rotatably mounted to the tower (12), the nacelle having a longitudinal axis and being configured to align the longitudinal axis with the direction of the incoming wind during operation of the wind turbine generator (10), one or more heat-generating components (22) housed in the wind turbine generator (10), and a containerized HVAC module (26) mounted on a roof (31) of the nacelle (14) and operably connected to the one or more heat-generating h components (22) for cooling the heat-generating components (22). The module (26) includes a shipping container (30) having a floor (32), a roof (34), a pair opposed longer side walls (36), a pair of opposed shorter end walls (38), and a longitudinal axis, the longitudinal axis of the shipping container (30) being oriented generally perpendicular to the longitudinal axis of the nacelle (14), the shipping container (30) having at least one heat exchanger (40) therein.
Abstract:
A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor-supporting assembly, the nacelle comprising a main unit, and at least one auxiliary unit. To increase flexibility and improve assembly and maintenance procedures of the wind turbine, the auxiliary unit comprises at least two sub units each accommodating at least one wind turbine component, e.g. a converter or a transformer. The sub units are attached individually to the main unit or they are joined and attached as one component to the main unit.
Abstract:
An offshore wind turbine comprising a tower, where said wind turbine at a level above sea level comprises at least one structure for storing at least one container, said container having the size and measures of a standard container, where said structure is arranged on the side of the tower, and a method of manufacturing such a concrete structure for an offshore wind turbine. The structure for storing one or more containers includes a deck, and at least one bed for supporting at least one container along the container's lower surface and/or edges, where the structure is a concrete structure. By manufacturing the structure from concrete, a very robust and strong structure is achieved.
Abstract:

A wind turbine is attached to the second end of the telescopic boom and the wind turbine is capable of transforming wind into electricity. The first end of the telescopic boom and the first retractable support leg are attached to the base. The mobile electricity generator can further comprise a first solar panel that is capable of transforming light into electricity, the base can further comprise an external surface, and the first solar panel can be attached to the external surface of the base. The mobile electricity generator can further comprise a battery in electric communication with the wind turbine and first solar panel and the battery can be capable of at least temporarily storing the electricity.
Abstract:
A three aerogenerator blades (1, 2, 3) packing system for transporting, handling and storing of aerogenerator blades (1, 2, 3). The prior art does not provide for cost-effective packing systems for sets of three blades. One aspect of the invention is directed to a method of packing three aerogenerator blades (1, 2, 3) and other aspect is directed to a packing system comprising a root frame (4) and a binding frame (5), wherein the blades (1, 2, 3) are in a edgewise position.
Abstract:
A linear-motion guiding device is disposed on the wall of the container. The wind turbine includes, at the lower end of the support column, a support-column lower end member capable of being fixed to the linear-motion guiding device. A slider of the linear-motion guiding device is provided with a guide member, and a bolt is inserted through a bolt insertion hole in the support-column lower end member and is screwed into a threaded hole in the guide member. The apparatus includes an attachment guide part including a stepped bolt and a flanged step part, the attachment guide part being configured to guide the support-column lower end member to a position and an attitude in which the bolt insertion hole in the support-column lower end member is aligned with the threaded hole in the guide member when the support-column lower end member is not fixed to the slider.
Abstract:
Wind energy systems and devices comprise a nacelle, a rotor driven alternator housed in the nacelle, a rotor connected to the alternator, and a load control system in communication with the alternator. The rotor includes a rotor hub and three or more rotor blades, and each blade has a foil shape and is connected to the rotor hub by a full foil attachment mechanism. The alternator is configured to operate at low rpm and to increase rotation speed without a step-up mechanism. The load control system is configured to anticipate changes in wind speed and adjust alternator load such that when wind speed increases the load control system adjusts the alternator load to optimize rotor rpm and optimize tip-speed ratio.

Abstract:
The mobile hybrid electrical power source (100) is reconfigurably disposed in a street-legal size compact metallic container (105) positioned on a hydraulic trailer (107) that can be towed by a truck. An alignment pin (109) is provided on the container (105) for aligning and mating the container with a rotary bearing (111) on the trailer (107). The rotary bearing (111) allows the metallic container (105) to rotate about a vertical central axis +/−180° from an initial position of the container (105). The generator (100) combines a plurality of power sources to provide optimal operation in multiple applications and conditions. The power sources comprise wind, solar, and fossil fuel energy components. When a power grid is available, the mobile hybrid electrical power source (100) can be connected to the grid to sell energy back to the grid.
