Abstract

The invention relates to a control system, a wind farm, and methods of optimizing the operation of a wind turbine. A control system (150) for a wind turbine (100) configured to generate an acoustic emission during operation includes a communication device (208). The communication device is configured to receive at least one penalty notification identifying a penalty to be assessed based on the acoustic emission generated. The control system also includes a processor (200) coupled to the communication device. The processor is configured to calculate an acoustic emission level to be generated by the wind turbine based on the penalty and based on at least one of a power generated by the wind turbine and an economic value attributed to the wind turbine, and adjust at least one characteristic of the wind turbine to cause the wind turbine to operate at the calculated acoustic emission level.

Description

technical field [0001] The subject matter described herein relates generally to wind turbines and, more particularly, to control systems, wind farms and methods for optimizing the operation of wind turbines. Background technique [0002] In general, a wind turbine includes a rotor including a rotatable hub assembly having a plurality of rotor blades. The rotor blades convert wind energy into a mechanical rotational torque that 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 rotor so that the generator efficiently converts the rotating mechanical energy into electrical energy, which is fed into the utility grid through at least one electrical connection. Gearless direct drive wind turbines also exist. The rotor, generator, gearbox and other components are typically mounted within a housing or nacelle positioned o...
