基于改进箱线图和ISMAHHO-KELM的变压器油中溶解气体体积分数预测
Gaoya dianqi油中溶解气体分析能够有效地揭示变压器内部的运行状况，在评估变压器运行状态和预测潜在故障方面具有重要作用。为此文中提出一种基于改进箱线图和ISMAHHO-KELM的变压器油中溶解气体体积分数预测方法。首先，为提高数据质量，利用基于中位偏差系数的改进箱线图对原始时间序列进行离群值检测和校正；然后采用变分模态分解对校正过的时间序列进行分解，得到多个子序列，以削弱时间序列的非平稳性；其次，通过核极限学习机模型预测子序列，同时提出改进黏菌—哈里斯鹰算法优化其超参数；最后，重构各子序列的预测值，得到最终预测结果 ...

Gaoya dianqi对变压器油中溶解气体浓度进行预测分析可为其运行状态评估提供重要依据，从而有效掌握设备状态发展趋势，为预警和检修提供参考。鉴于现有算法难以实现长期精确预测，文中首次提出一种基于策略梯度（policy gradient，PG）算法优化的变压器油中溶解气体体积分数预测模型。首先以门控循环单元（gate recurrent unit，GRU）为基础，引入编码器—解码器结构搭建Sequence to Sequence（Seq2Seq）网络模型，并且结合注意力机制和Scheduled Sampling算法 ...
