摘要： Systems and methods to provide for the controlled braking of a generator (e.g., a doubly-fed induction generator (DFIG)) in a wind power system are provided. In one example implementation, a method for braking a wind-driven doubly fed induction generator can include: receiving, by one or more control devices, a command to brake a wind-driven doubly fed induction generator; and generating, by the one or more control devices, a pulse width modulation scheme for the rotor side converter to provide a rotor side output to a rotor of the doubly-fed induction generator. The rotor side output includes a non-zero DC component and an AC component. The method includes controlling, by the one or more control devices, the rotor side converter in accordance with the pulse width modulation scheme. The non-zero DC component of the rotor side output can reduce a speed of rotation of the wind-driven doubly fed induction generator.

摘要： A method for locking the rotor of a wind turbine includes providing the rotor with at least one rotor blade which can be displaced about its longitudinal axis by an adjusting device from an operating position into a vane position, in which substantially no torque acts upon the rotor. The rotor drives a generator and can be prevented from rotation in a locking position by inserting a locking bolt into a rotor-side receiving opening. A wind turbine for performing the method includes a rotor which is induced into a creeping rotational movement at such a low rotational speed by short-circuiting at least one stator winding of the generator that a locking bolt can be inserted into a rotor-side receiving opening while the rotor is rotating.

摘要： The apparatus includes a wind turbine system for the collection of wind energy and the conversion thereof through staged-compression into highly compressed gas. The highly compressed gas is routed to a central tank, and then expanded into a plurality of concentric ring tanks, each storing gas at successively lower pressures. The cooling resulting from this expansion is utilized to cool hot compressed gas from an intermediate line of gas compressors, increasing the efficiency of the following compressors. This absorption of heat also improves the efficiency of the gas turbines driving electrical generators. The gas compressor in each wind turbine is located near ground level, and driven by a vertical shaft passing through the wind turbine support tower. One embodiment has conventional radially extending blades, and another embodiment has ducted blades to withstand higher winds. Both ground mounted and deep water adaptions for the wind turbines are disclosed.

摘要： The invention relates to a wind power station (1) for energy generation with an axial-flow, rotating, vortex-generating wind concentrator (2) pivot-mounted on a shaft (3), covered by a ring-shaped outer jacket (4) which on its outside features flow channels distributed over 360° and which is equipped concentrator blades (7) in a circular arrangement between the shaft (3) and the ring-shaped outer jacket (4). To create favorable conditions, it is proposed to include sawtooth-shaped, curved edge-vortex-generating guide profiles (5) producing a downstream vortex coil across the entire cross-section of the ring-shaped outer jacket (4).

摘要： A system and method for reducing oscillation loads of a wind turbine induced by high turbulence and/or combined with other environmental conditions are provided. The method includes determining at least one wind parameter at the wind turbine; monitoring an operating condition of the wind turbine; determining, by a processor, a variance of at least one of the monitored operating condition or a plurality of the wind parameters, wherein the variance is indicative of an oscillation occurring at one or more wind turbine components; determining, by a processor, an operating set point based on the variance; and, operating the wind turbine based on the operating set point when the variance indicates that the oscililation has a frequency within a certain frequency band so as to modify the frequency, wherein the modified frequency is outside of the frequency band and reduces oscillation loads occurring at the one or more wind turbine components.

摘要： The present invention provides an apparatus for the controlled rotation of a nacelle of a wind turbine, which includes a control device and n of yaw brakes. In standstill operation, the n yaw brakes are actuated to impart a standstill holding moment M1 for holding the nacelle, and the n yaw brakes impart a substantially equal first holding moment. In tracking operation, the n yaw brakes are actuated to impart a tracking holding moment, M2, which is lower than the standstill holding moment M1 (M1>M2). The control device, in tracking operation, actuates a number m of the n yaw brakes to generate substantially the same constant holding moment M3, where M1/n>M3>M2/n, and where the other (n−m) yaw brakes are actuated to generate substantially the same constant holding moment M4, where m*M3+(n−m)*M4˜=M2, and M1/n>M2/n>M4.
