In addressing the challenge of homologous matching for dual sets of recording channels in intelligent sub-stations of 220 kV and above,this paper presents a novel method employing regular expression and Jaccard index.To overcome the issue of irregular naming of recording channels,regular expressions to preprocess name texts of the channels are employed to ensure a standardized expression format.Furthermore,through Jieba word segmentation algorithm and stopword removal potential redundant information within the name texts of the channels.Subse-quently,the Jaccard similarity coefficient matching algorithm is employed to calculate the similarity between record-ing channel names,screening out homologous channels based on their similarity degrees.To validate the proposed method,simulations are conducted using actual recording file data from the power grid.The results affirm the effec-tiveness of the proposed method in achieving homologous matching of recording channels in intelligent substations.
