A lightweight fault diagnosis model for the main circulating pump of an ultra high voltage converter valve based on a multidimensional vibration feature graph
针对特高压换流阀阀冷系统中主循环泵故障特征提取难和故障诊断模型规模大的问题,提出一种基于多维振动特征图谱的轻量化主循环泵故障诊断模型.首先,基于振动轨迹图像(vibration locus image,VLI)和伪颜色编码的时域特征提取方法,构建主循环泵的时域特征图谱.其次,融合马尔科夫变迁场(Markov transition fields,MTF)和小波包变换(wavelet packet transform,WPT),全尺度提取振动信号的低…查看全部>>
A lightweight main circulating pump fault diagnosis model based on multidimensional vibration feature graph is proposed to address the difficulties in feature extraction and the large scale of fault diagnosis models in the cooling system of a ultra high voltage converter.First,a time-domain feature extraction method based on vibration locus images(VLI)and pseudo-color coding is proposed to construct the time-domain feature graph of the main pump.Secondly,by …查看全部>>
