20080197638 | Wind Turbine Comprising a Generator Cooling System - The present invention concerns a wind power installation comprising a pylon, a pod mounted rotatably on the pylon, a generator arranged within the pod and having a rotor and a stator, and at least one fan in the region of the pod. In order to reduce the entry of moisture, sand and other foreign substances into the pod and also to reduce the fan noise which reaches the exterior, in accordance with the invention there is provided an arrangement of the fan within the pod, wherein the fan sucks in outside air through a downwardly open first air gap, in particular between the pylon and the pod. In that respect the invention is based on the realization that the air flow along the wind power installation and in particular in the region of the pod has a markedly pronounced horizontal component and at best a markedly less pronounced vertical component. In other words the wind and therewith the foreign substances transported thereby flow at the windward side along the pod to the lee side and have then passed the wind power installation. If therefore air is sucked in through a downwardly open air gap, then at most very fine particles can still also be sucked in, which more specifically can be borne upwardly by the air flow, against the effect of the force of gravity. As a result the suction intake of relatively large particles of sand and dust and also the suction intake of raindrops which, as anyone knows, are considerably heavier, is reduced to a high degree, if not entirely prevented. | 08-21-2008 |

20090058096 | METHOD FOR MOUNTING A ROTOR BLADE OF A WIND POWER INSTALLATION WITHOUT USING A CRANE - It has already long been known to use mobile cranes for mounting rotor blades to a wind power installation. Such cranes pick up the rotor blade at the base of the wind power installation and take it to the rotor blade connection of the hub of the wind power installation so that the rotor blade can be connected to the hub. That connection is usually made by screw means, in which case screw bolts are let into the connecting flange of the rotor blade and project into corresponding bores in the rotor blade connection of the hub so that nuts can be screwed on to the screw bolts. The object of the invention is attained by a blade mounting method having the features of claim | 03-05-2009 |
20090068019 | ROTOR BLADE FOR A WIND POWER PLANT - The present invention concerns a rotor blade for a wind power plant having an aerodynamic profile comprising a rotor blade leading edge and a rotor blade trailing edge. The invention also concerns a rotor blade tip for a rotor blade having an aerodynamic profile with a pressure and a suction side, wherein the rotor blade tip is curved or angled in its end region in the direction of the pressure side of the rotor blade. In order further to reduce the levels of sound emission of wind power plants the rotor blade is curved or angled in its edge region in the direction of the trailing edge of the rotor blade in the plane of the rotor blade. In that respect the invention is based on the realization that, in the case of a rotor blade which does not go to a point at the tip, the effective rotor blade area is maintained unreduced precisely in the outer region in which the effect is greatest. The curve or angling of the end region of the rotor blade however provides that the trailing edge is displaced rearwardly in the end region of the rotor blade so that the flow at the rotor blade trailing edge is detached with a time delay in the outer region. Alternatively to attain the object of the invention a rotor blade can be developed in such a way that the ‘outer region’ narrows. That configuration of the rotor blade tip is based on the realization that the decreasing blade depth results in a reduced flow around the blade tip as the energy thereof is previously distributed to the trailing edge vortices but at the same time the effective rotor blade area is also reduced. The angling of the rotor blade tip provides that the effective rotor blade depth remains at its optimum as far as the angled rotor blade tip. | 03-12-2009 |

According to the invention that object is attained by a scissor lattice-like carrier structure and a working platform arranged on the carrier structure. In that respect the invention is based on the that the working platform assembly according to the invention can be adapted to different inside diameters of the tower-like building by virtue of the scissor lattice-like carrier structure and can thus extend completely across the tower cross-section. That makes it possible to work on the platform assembly. The working platform assembly can be released from the tower wall by the scissor lattice-like carrier structure and fixed again in another region of the building of a different cross-section. | 07-09-2009 |

20110081226 | METHOD FOR OPERATING A WIND TURBINE - The present disclosure relates to a method for operating a wind turbine with the steps: detection of the values of predetermined operating parameters by means of suitable sensors, detection of at least one predetermined initial condition, comparison of the detected values to stored values of the operating parameters. The disclosure further relates to a wind turbine for implementing the method. Therefore, the object of the present disclosure is, to be able to adapt the operation of a wind turbine to changes using a method of the type named above, such that when the detected parameter values deviate from the stored parameter values, as a function of the initial condition, either the stored parameter values are adapted to the detected parameter values or the operation of the wind turbine is influenced as a function of the detected parameter values. In this way, the disclosure is based on the knowledge that, from a pragmatic view, the formation of ice on a rotor blade is also a (temporary, meteorologically-related) change to the rotor blade shape. From this it follows that the formation of ice on the rotor blades always leads to a change of the aerodynamic profile and thus to a negative effect of the output of the wind turbine. However, deviations from this shape and thus deviations in the magnitude of the generated output also result just from manufacturing-dependent deviations of the rotor blades from the predetermined optimum shape and from gradual soiling of the rotor blades during operation. | 04-07-2011 |
