针对在小样本和复杂工况下高压断路器故障诊断识别精度不高的问题,提出一种基于振动信号处理和Ada Boost集成学习的高压断路器故障诊断方法。首先,搭建高压断路器实验平台并采集8种工况下的分闸振动信号。其次,对振动信号进行绝对值处理后,使用分段聚合近似(piec.wise aggregate approximation,PAA)进行分段平均,将输出的新序列采用格拉姆角场(Gramian angular field,GAF)转换成图片,并使用Relief F方法对提取的高维图片特征进行重要度排序。最后,将保留的重要特征输入到Ada Boost集成学习模型进行故障诊断,并用蛇优化算法确定最优PAA分段步长和输入分类器特征数量,以进一步提高故障诊断精度。通过分析多种信号处理方式及分类模型可知,图片信号和Ada Boost集成学习模型能够有效处理振动信号并准确判断故障类型,为准确、可靠地诊断高压断路器故障提供了新途径。

在输电线路巡检中，关键电力部件经常会出现锈蚀、脱落等缺陷，从而造成误检、漏检问题，导致人力成本大大增加。文中针对此类问题，提出一种基于YOLOv6的改进算法，主要在nec.部分增加了RepFPN结构，额外的增加了一个自底向上的路径聚合网络，从而增强输出特征的表达能力，提升模型性能，然而增加了计算成本。为了降低计算量，增加了RepVGG结构，它有着类似残差的结构，拥有丰富的梯度信息，经实验数据表明，当使用3个RepVGG结构替代c.层时，会提升1～2点精度；同时将c.nvBNAc.的算子进行融合后，只需要采用一个c.nv+inplac. ac.ivation就可以完成原有的3次Op计算，绝大多数情况下还能得到一致的数值结果，缓解了上述改进增加计算量的问题。实验表明，改进后的模型m AP＿0.5:0.95提高了12%，精确度提高了3.9%，各项loss值显著降低，同时很好地检测出了电力部件各种缺陷以及输电线路上的异物。

针对换流变压器状态评估中的数据匮乏以及各评价指标间的相互中和等问题,提出一种将变权理论和靶心贴近度相结合的换流变压器状态评估模型。首先,考虑到实际案例中指标的动态发展,采用变权模型根据指标量的劣化程度进行变权处理;其次,为了达到降低数据需求并能准确评估换流变压器状态的目的,采用靶心贴近度模型确定换流变压器对各个状态等级的贴近度;最后,采用隶属度函数将靶心贴近度转化为隶属度并计算换流变压器最终状态情况。实际案例表明:文中提出的状态评估模型不仅能够有效地评估换流变压器的健康状态而且同样适用于电力变压器,在保证评估准确率的前提下,数据需求小,评估过程简单直接,具有实用价值与参考意义。

针对电力设备缺陷文本信息的知识挖掘与分析任务中存在缺陷文本特征信息提取不足、缺陷文本分类精度不够的问题,提出一种基于BERT(bidirec.ional enc.der representations from transformers)的双分支特征融合的电力设备缺陷文本分类模型。首先,对缺陷文本数据进行预处理,删除异常缺陷文本,并归纳了电力设备缺陷文本特点;然后,采用BERT模型作为文本编码器,将文本转化为向量后分别输入至BiLSTMAttention(attention-based bidirec.ional long short-term memory)模块和多分支c.N(multi-sc.le c.nvolutional neural network,Mc.N)模块,提取缺陷文本语义信息特征和局部关键信息特征;最后,将所提取出的语义特征和多维关键特征向量进行融合,并通过Softmax层实现对缺陷文本分类。与基准模型BERT-BiLSTMAttention相比,其准确率、召回率及F1值分别提高了2.76%、3.58%和4.39%,表明所建模型在缺陷文本分类任务中性能的优越性。

针对传统云运动轨迹预测方法存在的预测精度差、空间结构细节信息丢失等问题,提出一种基于时空长短时记忆(ST-LSTM)神经网络的地基云图预测模型。首先使用卷积编码网络提取输入视频流的高维图像特征;然后在特征提取模型中对图像潜在信息进行多分支获取,一部分使用ST-LSTM神经网络提取不同帧之间的时空特征,另一部分将图像序列进行分解,并通过基于门控机制的记忆融合网络来获取分解后图像中的结构细节信息;最后将得到的分支特征进行组合后经过解码网络输出最终的预测视频流。在地基云图、Moving MNIST和Human 3.6M数据集上的实验结果表明,在图像预测准确率、结构细节信息保留效果以及人眼主观感受上,该预测模型均优于对比模型。与基准模型TaylorNet相比,所提模型在Moving MNIST数据集上均方误差指标和平均绝对误差指标分别降低15.7%和11.8%,在地基云图数据集上,其结构相似性指标与峰值信噪比指标分别提升1%和3.2%,且生成的视频流数据更为清晰,能够更准确地描述云层未来的运动状况,从而更可靠地预测光伏电站未来的输出功率。

Lower extremity injury and deformity c.n result from a number of etiologies. Regardless of the underlying c.use, the dec.sion to pursue amputation or rec.nstruc.ion of a lower limb is c.allenging for both patients and *** dec.sion is largely dependent on the patient's premorbid health and func.ion, func.ional goals and preferenc.s,and c.arac.eristic. and viability of the affec.ed limb. The role of adaptive devic.s following surgery should never be underestimated. Advanc.s in prostheses and orthoses have provided patients with a wider range of options to c.nsider when dec.ding between limb rec.nstruc.ion and amputation. The primary goals of any adaptive devic. are to improve func.ion, prevent rec.rrenc. or ulc.ration of the defec., and allow for use of c.nventional footwear and/or *** a lower extremity amputation is indic.ted, selec.ion of the c.rrec. level is of c.itic.l importanc. in order to optimize healing potential and func.ion. Eac. distinc. level has c.rtain inherent prosthetic.and orthotic.c.nsiderations. Likewise,the applic.tion of an adaptive devic. following rec.nstruc.ion of the lower extremity also has demonstrable benefits and must be tailored to the spec.fic.defec. and proc.dure performed. Knowledge of available prosthetic.and orthotic.options is of c.nsiderable importanc. for the rec.nstruc.ive surgeon tasked with limb salvage or resurfac.ng an amputated extremity. This artic.e reviews c.nsiderations of various types of lower extremity amputation and rec.nstruc.ion, and provides a framework for the role of adaptive devic.s following surgery.
