29 Jun 2010TL;DR: In this article, the authors proposed a method of calculating an electrical output of a wind power plant comprising a plurality of wind turbines, taking into account parameters which may vary stochastically throughout the wind power plants, e.g. pitch angle, stiffness in drive train, different possible production with regard to reactive and active effect, mechanical component properties as well as variability in relation to communication times between a power plant controller and the individual wind turbines.
Abstract: The invention relates to a method of calculating an electrical output of a wind power plant comprising a plurality of wind turbines. Instead of calculating the electrical output of the wind power plant as a simple aggregation of the outputs of each wind turbine, the method takes into account parameters which may vary stochastically throughout the wind power plant, e.g. pitch angle, stiffness in drive train, different possible production with regard to reactive and active effect, mechanical component properties as well as variability in relation to communication times between a power plant controller and the individual wind turbines. The method proposes to make adjustment to a simple aggregation calculation method based on analysis of such stochastic varying parameters.

04 Aug 2011TL;DR: In this article, an apparatus for forming a trailing edge of a wind turbine blade having first and second shells is described, and an engaging element is configured to securely support a turbine blade.
Abstract: An apparatus (60) is provided for forming a trailing edge (52) of a wind turbine blade having first and second shells (40, 42). The first and second shells define a gap therebetween, and the apparatus has a first mold component (62) that is adapted to form the first or second shell, and an engaging element (77). The engaging element is configured to securely support a trailing edge component to be coupled to the first and second shells. The engaging element is coupled to the first mold component. The apparatus may additionally include a second mold component (64) that is adapted to form the other of the first or second shells and which is coupled to the first mold component. In this embodiment, the first and second mold components have a closed position in which the first and second shells are closed over one another so as to define a generally closed profile of the wind turbine blade.

TL;DR: In this paper, a wind power plant where the driving shaft communicates with a synchronous generator (3) optionally through a gear (2) and with a transformer, if any, communicating through an AC/DC inverter 7 with an HVDC transmission cable is described.
Abstract: A wind power plant where the driving shaft communicates with a synchronous generator (3) optionally through a gear (2) and with a transformer, if any, communicating through an AC/DC inverter 7 with an HVDC transmission cable 9 The synchronous generator (3) is connected to a magnetic field controller (3) In response to an output parameter, such as the power generated by the synchronous generator (3), this magnetic field controller (4) is adapted to vary the magnetic field in the generator (3) in response to said output parameter As a result it is possible to compensate for a possible variation in the output parameter, whereby said output parameter is stabilized As a result it is possible to compensate for a varying speed of rotation

03 Jul 2012TL;DR: In this article, a wind turbine in which the yaw speed of a rotor (4) of the wind turbine (1) is increased, in a direction to reduce yaw error, from a first speed to a faster second speed, is shown.
Abstract: A wind turbine (1) in which the yaw speed of a rotor (4) of the wind turbine (1) is increased, in a direction to reduce yaw error, from a first speed to a faster second speed when at least one of a yaw error threshold and a rate of change in yaw error threshold is exceeded. Yaw error is an amount an axis about which the rotor (4) is rotatable is offset from the wind direction to which the rotor (4) is exposed. As a result, the maximum loads that a wind turbine 1 should withstand may be reduced and lighter wind turbine components result.

28 Jan 2011TL;DR: In this paper, a nacelle for a wind turbine and a method for erecting it is described, where the main unit and at least one of the side units are arranged side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine.
Abstract: A nacelle (2) for a wind turbine (1) and a method for erecting a wind turbine (1) are disclosed. The nacelle (2) comprises a main unit (8) arranged to be connected to a wind turbine tower (3), via a yawing arrangement, and at least one side unit (9a, 9b, 9c, 9d) mounted along a side of the main unit (8) in such a manner that direct access is allowed between the main unit (8) and the side unit(s) (9a, 9b, 9c, 9d), each side unit (9a, 9b, 9c, 9d) accommodating at least one wind turbine component (13, 14, 15, 16, 17), and at least one side unit (9a, 9b, 9c, 9d) being capable of carrying the wind turbine component(s) (13, 4, 15, 16, 17) accommodated therein. The main unit (8) and at least one of the side unit(s) (9a, 9b, 9c, 9d) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine (1). A sufficient interior space of the nacelle (2) is obtained while allowing the nacelle (2) to be transported due to the modular construction. The weight of the wind turbine components (13, 14, 15, 16, 17) is arranged close to the tower (3) due to the transversal arrangement of the side unit(s) (9a, 9b, 9c, 9d) relative to the main unit (8).
