摘要

提出了一种考虑风机运行特性的劣化态势感知算法。首先

提出了一种基于损伤累积理论的动力学劣化态势指标

通过Hertz理论计算轴承劣化度(DL);其次

提出了一种结合混合长短期记忆(LSTM)-CatBoost预测器(HLCP)的劣化预测方法

通过引入轴承转速作为时间序列输入的方法

考虑风机运行特性的影响

预测劣化度增长值;基于仿真模型计算轴承损伤临界值

从而预测轴承剩余寿命;最后

使用我国北方某风电场的振动和数据采集与监视控制系统(SCADA)数据进行验证。结果表明:所提出的劣化态势指标在预测趋势与历史趋势上的相似度约为74.42%

具有明显的趋势性和单调性;基于HLCP模型得到的剩余寿命预测结果与实际失效时间的误差仅为640 h

相较于未考虑风机运行特性的预测方法

误差减少了16 461 h。

Abstract

A deterioration trend perception algorithm considering the operating characteristics of wind turbines was proposed. Firstly

a kinetic deterioration state indicator based on damage accumulation theory was proposed

and the bearing deterioration level (DL) was calculated by Hertz theory. Secondly

a hybrid long short-term memory (LSTM)-CatBoost predictor (HLCP) deterioration prediction method was proposed. The deterioration growth value was predicted by considering the influence of wind turbine operating characteristics and introducing the bearing speed as a time series input. Then

the critical value of bearing damage was calculated based on the simulation model

so as to predict the remaining bearing life. Finally

it was validated using the vibration and supervisory control and data acquisition (SCADA) data from a wind farm in the north of China. Results show that the proposed deterioration state indicator has a similarity of about 74.42% in predicting trend and historical trend

with obvious trend and monotonicity. The error between the remaining life prediction results obtained based on the HLCP model and the actual failure time is only 640 h

which is 16 461 h less compared to the prediction method that does not take into account the turbine's operating characteristics.
