Detection and Classification of Transmission Line Faults Based on Unsupervised Feature Learning and Convolutional Sparse Autoencoder

Chen, Kunjin, Hu, Jun, He, Jinliang·2016·IEEE Transactions on Smart Grid

Abstract

We present in this paper a novel method for fault detection and classification in power transmission lines based on convolutional sparse autoencoder. Contrary to conventional methods, the proposed method automatically learns features from a dataset of voltage and current signals, on the basis of which a framework for fault detection and classification is created. Convolutional feature mapping and mean pooling are implemented in order to generate feature vectors with local translation-invariance for half-cycle multi-channel signal segments. Fault detection and classification are achieved by a softmax classifier using the feature vectors. Further, the proposed method is tested under different sampling frequencies and signal types. The generalizability of the proposed method is also verified by adding noise and measurement errors to the data. Results show that the proposed method is fast and accurate in detecting and classifying faults, and is practical for online transmission line protection for its high robustness and generalizability.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
