Ground stray current characteristic site determination method, device and system and medium

Abstract

The invention provides a ground stray current characteristic site determination method, device and system and a medium, and the method comprises the following steps: A, obtaining related data of ground stray current, the related data comprising the ground stray current of each transformer substation and a corresponding stray current type, the stray current type comprises urban rail transit stray current, direct current transmission project stray current, geomagnetic storm stray current and a negative sample; b, preprocessing the data according to the related data of the ground stray current obtained in the step A; c, determining an optimal ground stray current characteristic site according to the data preprocessed in the step B; by comprehensively considering the missing rate and the abnormal rate of the monitoring data of the ground stray current of each transformer substation, the generalization performance of the training model and the like, whether the transformer substation can be used as a characteristic site of the ground stray current or not is determined, a data basis can be provided for identification of a ground stray current event, and treatment of the ground stray current is assisted.
