  • Description: Abstract Accurate grading of relay protection device (RPD) defects can improve the maintenance and reliability of RPD to ensure the safety of power grid. Based on the text record of defects of RPDs in a regional power grid and the defect text dictionary, this paper analyses the defect grading method with Term Frequency-Inverse Document Frequency (TF-IDF) assignment method and simple classifiers. The details are as follows: firstly, the construction of relay protection devices defect dictionary is introduced. Secondly, the vectorization text of relay protection devices defect is formed; combined with TF-IDF assignment method, and then, the relay protection devices defect grading models based on five simple classifiers are constructed respectively. Finally, the performance of the above defect grading methods is compared and analysed based on the k -fold crossover method. The grading models constructed in the paper can provide an auxiliary to relay protection device operation.
