A cooperative active control method for long-distance noise transmission and power generation of wind turbines

Abstract

The invention discloses a cooperative active control method of long-distance noise transmission and power generation of a wind turbine, including processing and monitoring high-precision meteorological data, calculating the aerodynamic noise source of the wind turbine, calculating the noise transmission loss of the wind turbine, and operating the cooperative control of the noise and power of the wind turbine The method has several steps; on the premise of ensuring that the noise of the residents meets the standard, the wind turbine can be intelligently controlled to perform actions such as variable speed and pitch, and reduce economic losses caused by noise reduction.

Description

technical field [0001] The invention belongs to the field of wind turbines, and in particular relates to a cooperative active control method for long-distance noise transmission and power generation of wind turbines. Background technique [0002] Wind energy is an important part of renewable energy and an important guarantee for my country to achieve the goal of non-petrochemical energy accounting for 20% of total energy consumption (2030). At the same time, wind power is also a strategic industry for the sustainable development of energy in my country, and its development prospects in this century are broad and certain. Since the 1970s, the installed capacity of wind power has increased rapidly. Up to now, the installed capacity of wind power in China has accounted for about a quarter of the world, and it has maintained a continuous growth. Recently, as the installed capacity of onshore wind power in high wind speed areas tends to be saturated, onshore wind power is develo...

AI Technical Summary

Problems solved by technology

None of the above methods can accurately guarantee that the noise in residential areas meets the standards.

And it will bring huge economic losses due to simple speed reduction and shutdown measures

[0004] Therefore, the traditional non-intelligent wind turbine noise control method can no longer meet the requirements of low wind speed, close to residential areas, and complex terrain.
