Embodiment Construction

[0056] Features and exemplary embodiments of various aspects of embodiments of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the invention.

[0057] The invention provides a wind power generating set noise reduction system and method, a control device and a storage medium thereof. The noise reduction system can handle noise in the full frequency range, thereby improving the noise reduction effect of the wind turbine and eliminating noise troubles for residents near the wind farm. At the same time, the noise reduction system of the wind power generating set in the embodiment of the present invention has the advantages of saving energy and reducing consumption.

[0058] like figure 1 and figure 2 As shown, the wind power generating set is generally composed of three blades 101 , and the three blades 101 are symmetrically fix...

Abstract

The invention discloses a wind generating set noise reduction system and method, a control device and a storage medium thereof. The noise reduction system comprises a monitoring unit used for monitoring running state data of a wind generating set, multiple stages of noise reduction units installed in a zone between the wind generating set and a residential area from close to far and a controller used for judging whether all stages of noise reduction units meet the corresponding starting conditions or not according to the running state data of the wind generating set; each stage of noise reduction unit is used for generating reverse sound waves opposite to original noise at the position in phase, and each stage of noise reduction unit corresponds to one starting condition and one stopping condition; and if any noise reduction unit meets the corresponding starting condition, the noise reduction unit is controlled to be started until the noise reduction unit meets the corresponding stopping condition, and the noise reduction unit is controlled to stop running. By means of the technical scheme in the embodiment, the noise reduction effect of the wind generating set can be improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a noise reduction system and method for a wind power generating set, a control device and a storage medium thereof. Background technique [0002] In recent years, the development and utilization of wind energy as a clean energy has been paid more and more attention. Most remote areas with good wind energy resources have built wind farms, and there are multiple wind turbines (hereinafter referred to as fans) installed in the wind farms. A large amount of noise is generated during the operation of the fan, and the characteristics of the noise are different in different locations. For example, the noise generated when the blade sweeps the wind has the characteristics of large area, multiple generation points, and large frequency range; the noise generated by the yaw system during operation has the characteristics of high frequency and harshness; the noise generated by ...
