Embodiment Construction

[0022] Reference will now be made in detail to the various embodiments, one or more examples of which are illustrated in the figures. Each example is provided by way of explanation, not limitation. For example, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield yet a further embodiment. The present disclosure is intended to cover such modifications and variations.

[0023] Embodiments described herein include wind turbine systems that enable efficient resonance damping. More specifically, they include wind turbine systems adapted to alter the operating conditions of the grid to which the turbine(s) are connected.

[0024] Embodiments described herein include a grid adaptive resonance damper. This damper is a function in the main turbine controller that uses the torque control capabilities of modern wind turbines to dampen mechanical resonances of the turbine, such as drive train vibration, tower Side...

Abstract

A resonance damping system for a wind turbine having a generator connected to a power grid, the resonance damping system comprising an adaptive resonance damper, operable to provide a control signal for the generator, wherein the variable torque signal of the adaptive resonance damper is automatically adjusted according to a parameter which represents a grid condition.

Description

technical field [0001] The subject matter described herein relates generally to methods and systems for resonance damping, and more particularly, to methods and systems for resonance damping in wind turbines. Background technique [0002] Generally, a wind turbine includes a turbine having a rotor including a rotatable hub assembly having a plurality of blades. The blades convert wind energy into mechanical rotational torque, which drives one or more generators through the rotor. The generator is sometimes, but not always, rotationally coupled to the rotor through a gearbox. The gearbox increases the inherently low rotational speed of the generator's rotor to efficiently convert rotational mechanical energy into electrical energy that is fed into the grid through at least one electrical connection. There are also gearless direct drive wind turbines. The rotor, generator, gearbox and other components are typically mounted within a housing or nacelle positioned on top of a ...
