Wind power generation noise monitoring reduces wind

Does wind turbine aerodynamic noise affect health condition monitoring (HCM)?

This paper reviews the wind turbine aerodynamic noise and mechanical noise mechanism and the de-noising methods in healthy condition monitoring (HCM). Fast development of the wind farm brings the problem of noise pollution, which can influence both the environment and the safety running of the turbine.

What is wind turbine noise?

Wind turbine noise Noise generated from wind turbines are mainly of two types- mechanical and aerodynamic. Mechanical noise is generated from various machinery components in the wind turbine and is tonal in character.

How to reduce noise in a wind turbine?

Several techniques for noise mitigation have been discussed. Methods like serrated trailing edges for trailing edge noise reduction are already being used in some turbines but more effective methods for noise control are needed.

Does wind turbine noise affect human life?

Conclusions The present paper reviewed several wind turbine noise mechanisms and mitigation methods along with the impact of noise from wind turbines on human life. Wind turbine noise is found to be more annoying than other community noise sources.

How do regulations affect wind turbine noise generation?

Regulations are important impacting possible site locations and, therefore, the growth of wind energy. Solving the issues associated with wind turbine noise generation will go a long way in promoting wind as one of the alternative energy generation technologies.

How do wind turbine blades reduce aerodynamic noise?

The largest contributor to aerodynamic noise comes from the trailing edge of wind turbine blades. Strategies for reducing aerodynamic noise include adaptive solutions and wind turbine blade modification methods.
