摘要
针对风力发电场风力不可控、风况复杂和数据的非平稳性现状,利用风力发电场SCADA大数据,对风力发电机组进行分析,提出一种基于小波分析和神经网络的智能算法,通过分析风力发电机相关故障信号的特征,实现对风力发电机的故障诊断和预测。最后对大熊山风电场2MW 风力发电机组运行数据进行仿真和分析,仿真结果表明,小波神经网络是一种风力发电机故障诊断和预测的有效方法。
In view of the wind power uncontrollability,complex wind conditions and the non-stationary status of data in a wind farm,the SC ADA big data of wind turbine is utilized to analyze the wind turbine and a prediction method of wind turbine faults is proposed based on the wavelet neural network.Firstly,an intelligent algorithm based on the wavelet analysis and the neural network is proposed.Then,The characteristics of generator-related fault signal are analyzed to predict and diagnose the wind turbine fault based on the proposed algorithm.Finally,an example of 2 MW wind turbine generators on Damingshan Wind Farm are simulated and analyzed.It is shown that the wavelet neural network is effective for the prediction and diagnosis of wind turbines fault.
