AI Technical Summary

Technical Problem

The existing wind turbine nacelles are rigidly connected structures, which make it difficult to effectively absorb and buffer multi-dimensional, high-intensity vibration energy, leading to vibration resonance, wear, noise pollution, and equipment reliability issues, affecting power generation efficiency and lifespan.

Method used

It adopts a double-layer vibration reduction structure, including a first vibration reduction component connecting the tower and the nacelle shell, and a second vibration reduction component connecting the nacelle shell and the mounting platform. Combined with a non-contact balancing component and a dual noise reduction component, it achieves multi-stage vibration reduction and noise reduction through magnetorheological fluid dampers and acoustic wave counter-damping technology, and is cooled by a heat dissipation component.

Benefits of technology

It significantly reduces vibration and noise, extends equipment life, improves the operating environment, reduces maintenance costs, and enhances equipment stability and power generation efficiency.

Abstract

A vibration-damping and noise-reducing wind turbine nacelle and its control method are disclosed. Specifically, the vibration-damping and noise-reducing wind turbine nacelle includes a nacelle shell, a mounting platform, a first vibration damping component, a second vibration damping component, a non-contact balancing component, a first noise reduction component, a second noise reduction component, and a heat dissipation component. One end of the first vibration damping component is mounted to the tower, and the other end is mounted to the nacelle shell. The first vibration damping component is used to dampen the vibration of the nacelle shell. The mounting platform is mounted inside the nacelle shell via the second vibration damping component. Based on the above, this invention proposes a vibration-damping and noise-reducing wind turbine nacelle and its control method, solving the problem that existing generator nacelles are typically rigidly connected structures, making it difficult to effectively absorb and buffer multi-dimensional, high-intensity vibration energy, affecting the generator's power generation efficiency, equipment reliability, and overall service life, and the noise generated may affect operators and the surrounding ecological environment.
