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 ...
