Embodiment Construction

[0015] Embodiments described herein facilitate operating one or more wind turbines at a site by automatically responding to noise levels within or near the site. Noise levels can be determined by direct measurement and / or by calculating noise levels based on wind turbine characteristics (e.g., wind turbine size, blade geometry, and / or blade surface roughness) and / or operating conditions (e.g., wind speed and / or wind direction) . Operational adjustments may be communicated to one or more wind turbine controllers coupled to the wind turbines when the overall noise level representing noise from multiple wind turbines within the site deviates significantly from the target noise level.

[0016] Target noise levels may include, but are not limited to, noise levels defined by regulations (e.g., regulations issued by municipalities or other government agencies), by contractual or title-based specifications, or by the preferences of operators of wind turbine sites . For example, a ta...

Abstract

The invention relates to a system, a device, and a method for noise-based wind turbines operation. The system for use in operating a plurality of wind turbines is provided. The system includes a plurality of wind turbine controllers, each wind turbine controller of the plurality of wind turbine controllers operatively coupled to a wind turbine of a plurality of wind turbines, and a site controller coupled in communication with the plurality of wind turbine controllers and is configured to determine an aggregate noise level at a geographic position based on a plurality of noise levels associated with the plurality of wind turbines, compare the aggregate noise level to a target noise level associated with the geographic position, and when the aggregate noise level exceeds the target noise level, transmit an operational adjustment to a first wind turbine controller of the plurality of wind turbine controllers, wherein the first wind turbine controller is operatively coupled to a first wind turbine, and a noise level associated with the first wind turbine is reduced when the first wind turbine controller applies the operational adjustment.

Description

technical field [0001] The subject matter described herein relates generally to operating wind turbines, and more specifically, to automatically adjusting operation of one or more wind turbines based on a comparison of an overall noise level to a target noise level. Background technique [0002] A wind turbine harnesses the energy of the wind to generate or generate electricity. The operation of one or more wind turbines on a site generates noise that may be audible at locations adjacent to the site. Since this noise can be considered a nuisance, a maximum noise level can be imposed. [0003] To comply with restrictions on noise levels, operators of wind farms may operate one or more wind turbines at less than full level of operation (eg, power output). However, choosing an operating level that ensures that noise levels remain below maximum levels can have a significant negative impact on the output of a wind farm. Furthermore, adjusting operating levels based on changing...
