基于PLO-SVMD与CNN-BiGRU-ATT的直流微电网故障诊断方法
Gaoya dianqi针对因噪声干扰而导致直流微电网故障识别精度下降的问题，提出一种基于PLO-SVMD与CNN-BiGRU-ATT的故障诊断方法。首先，以最大互信息系数（MIC）为适应度函数，采用极光优化算法（PLO）优化逐次变分模态分解（SVMD）中的惩罚因子，提升信号分解质量与稳定性。其次，依据特征指标筛选出与故障特性高度相关的模态分量，抑制噪声干扰并完成信号重构。最后，构建CNN-BiGRU-ATT分类模型，融合卷积神经网络（CNN）的局部提取能力，双向门控循环单元（BiGRU）的时序建模能力以及注意力机制（ATT ...

基于小样本随机森林模型的低气压下室内设备空气放电故障识别方法研究
Gaoya dianqi空气绝缘的室内电力设备发生放电故障时，利用半导体气体传感器检测空气放电分解物的成分和含量，能够判断放电故障的严重程度，因此研发智能、精准的机器嗅觉算法对监测室内电力设备的正常运行有着重要意义。本文搭建了空气放电实验平台，模拟了低气压高海拔条件下的火花和局部放电故障，通过基于半导体传感器阵列的空气放电分解物检测装置对不同放电故障的气体分解物进行特征提取，然后利用基于主成分分析的小样本扩充增强方法对数据集进行丰富和精简，最后采用随机森林算法对放电分解故障进行分类。结果表明随机森林算法平均识别准确度97.22%
