摘要

发电机定子铁芯温度异常可能导致绝缘材料老化、绕组短路等严重问题，进而影响发电机的整体性能和寿命。提出一种基于FFCM-MHDA-iTransformer的汽轮发电机定子铁芯温度预测模型，充分利用改进的Transformer架构，即倒置Transformer(iTransformer)模型，使用倒置的时间序列编码方式，解决Transformer在处理多元变量相关性方面的局限；采用融合傅里叶卷积混合器（fused Fourier convolution mixer

FFCM）实现对时序数据的局部特征提取和增强；使用多头差分注意力机制（multi-head differential attention

MHDA）替换传统自注意力，有效消除注意力噪声，促使模型关注关键信息。经过训练和验证，与其他主流预测模型相比，该模型具有更高的预测精度，有助于及时发现潜在故障，避免停机检修，对保障汽轮发电机稳定运行具有重要应用价值，有效地提升了温度预测技术的准确性与实用性。
