Power distribution network fault detection method based on convolutional neural network

Abstract

The invention provides a power distribution network fault detection method based on a convolutional neural network, which provides the technical support for the three problems of a fault type, a faultphase and a fault position, and comprises the following steps of S1, collecting a power distribution network fault data set; S2, performing data preprocessing on the current sequence data by utilizing the simplified Hilbert-Huang transform; S3, initializing a convolutional neural network designed by the patent; S4, training the convolutional neural network by using the preprocessed data; and S5,testing the fault detection method by using the test set. According to the method, by utilizing the convolutional neural network and the simplified Hilbert-Huang transform, the fault type, phase and position of the power distribution network can be accurately judged, and meanwhile, compared with a method for carrying out fault judgment by utilizing a recurrent neural network, the speed is greatlyincreased.

Description

technical field [0001] The invention belongs to the technical field of deep learning, and in particular relates to a distribution network fault detection method based on a convolutional neural network, which uses a convolutional neural network and a simplified Hilbert-Huang transform to detect distribution network faults. Background technique [0002] In today's society, electricity, as the main energy source, plays a vital role in daily work and life.
