A residual current classification algorithm based on AdaBoost

Abstract

Current residual current action protection device cannot detect the type of residual current in the electric shock current. In this paper, an electric shock test platform is built and the residual current data is obtained by experiment. Based on the above data, this paper presents a residual current classification method based on the AdaBoost algorithm, which firstly obtains the characteristic components of different types of residual current components, and then maps these component features to the AdaBoost algorithm. The type of electric shock current in total residual current is detected by AdaBoost algorithm. Compared with SVM and random forests, the results show that the proposed method has some advantages, which can provide theoretical basis and support for the development of the subsequent adaptive residual current action protection device.
