Embodiment Construction

[0018] As used herein, the term "vane" is intended to mean any device that provides a reaction force when in motion relative to the surrounding fluid. As used herein, the term "wind turbine" is intended to mean any device that generates rotational energy from wind energy - and more specifically converts kinetic energy of wind into mechanical energy. As used herein, the term "wind generator" is intended to mean any wind turbine that generates electrical power from rotational energy produced by wind energy - and more specifically converts mechanical energy converted from kinetic energy of the wind into electrical power. As used herein, the term "windmill" is intended to mean the use of rotational energy generated from wind energy - and more specifically mechanical energy converted from the kinetic energy of wind - for an intended purpose other than generating electrical power (such as, but not limited to, Any wind turbine that pumps fluids and / or abrasive substances).

Abstract

A wind turbine (10) comprising at least one turbine (24), a generator (26) configured for converting torque into electrical power, and a controller (40) capable of comparing a wind turbine (10) acoustical profile and a wind turbine (10) power profile to determine a noise reduced operational condition, the controller (40) further being capable of controlling the wind turbine (10) to provide a rotor speed and the pitch angle of the turbine (24) corresponding to the noise reduced operational condition.

Description

technical field [0001] The present disclosure relates to methods and systems for controlling noise emissions in wind turbines. In particular, the present disclosure relates to methods and systems for controlling noise emissions of wind turbines while maintaining a desired power factor. Background technique [0002] Wind energy systems have gained increasing importance as an energy source in recent years. Due to the relative scarcity of land suitable for their economical operation in many countries, a growing number of wind energy systems are located near populated areas. Since the operation of wind turbines in a wind energy system results in noise emissions, this can cause various problems, such as resistance from surrounding areas and the like. Various factors contribute to the overall noise emissions of such systems, such as tonal and aerodynamic noise emissions. In some locations and regions, local ordinances or other regulations limit permissible noise emissions. [...
