基于改进MPE和K-medoids的变压器绕组松动故障诊断

Gaoya dianqi
为了更加有效地对变压器绕组松动故障进行诊断，针对变压器有载运行时的振动信号，提出了一种基于改进多尺度排列熵（MPE）和K-medoids的变压器绕组松动故障诊断方法。首先采用粒子群优化（PSO）的MPE算法对绕组不同状态下的变压器振动信号进行特征提取，以减少MPE算法中参数设置对故障类型识别精度的影响，然后通过K-medoids聚类算法诊断变压器绕组松动故障，以完成故障的分类识别。对某10 kV变压器的绕组松动故障模拟实验结果表明，绕组不同状态下变压器振动信号的MPE值经PSO参数优化后存在明显差异 ...
