摘　　要：把小波和模式匹配技术引入了电力变压器色谱倾斜峰辨识领域;该方法为:先用小波技术提取色谱曲线大致的基线,然后扣除基线,消除由于基线漂移引起的色谱峰倾斜,再用基于模式匹配的色谱峰辨识方法查找色谱峰位;对该方法进行了实验研究,结果表明:该方法能辨识由于色谱基线漂移引起的倾斜峰的峰位。The wavelet and mode matching-based technology was introduced to the field of transformer chromatogiam gradient peaks identification.The program of the method is that,firstly,extracting a preparatory baseline using wavelet filter,secondly,subtracting the preparatory baseline from the chromatogram data to weaken the excursion of baseline,thirdly,find peak positions using the mode matching-based chromatogram peaks identification algorithm.A experiment was researched using the method,results showed that the method can find the gradient peaks＇ positon of transformer chromatogram.
