摘要

风力机齿轮箱是将转子轮毂的转速传递给发电机的关键设备，其运行状况是风力机运行效率和可靠性的体现。行星齿轮组作为风电齿轮箱的初始阶段，容易受到复杂的结构、其他高速阶段的振动和背景噪声的影响，其故障特征提取具有一定的挑战性。本文将双Q因子小波稀疏分解方法应用于风电行星齿轮箱故障特征提取。考虑小波系数的稀疏性，将振动信号迭代分解为高Q分量和低Q分量。故障特征一般隐藏在低Q分量中。通过进一步解调，可以很容易地检测出行星齿轮的故障信息。

Application of Double Q Wavelet-based Sparse Decomposition to Fault Feature Extraction of Wind Turbine Planetary Gearbox

The wind turbine gearbox is a critical equipment transforming the speed of the rotor hub to the generator, the condition of which is the reflection of operational efficiency and reliability of wind turbines. As the initial stage of the wind turbine gearbox, the fault feature extraction of the planetary gear set is challenging since it is prone to be affected by complicated structure, vibration from other high-speed stages and background noise. In this paper, a double Q factor wavelet-based sparse decomposition is applied to the fault feature extraction of the wind turbine planetary gearbox. Considering the sparsest wavelet coefficients, the vibration signal is iteratively decomposed into high Q and low Q components. The fault feature is generally hidden in the low Q component. With further demodulation, the fault information of planetary gears can be easily detected.
