Prediction and Fault Detection of Environmental Signals with Uncharacterised Faults
Proceedings of the AAAI Conference on Artificial Intelligence, 2021 Many signals of interest are corrupted by faults of anunknown type. We propose an approach that uses Gaus-sian processes and a general “fault bucket” to capturea priori uncharacterised faults, along with an approxi-mate method for marginalising the potential faultinessof all observations.

Redundant ADS and INS High Sensitivity Fault Detection Method
Xibei Gongye Daxue Xuebao, 2020 The fault detection function of GLT method is approximately proportional to the square of fault value, the value of the fault detection function is lower than the detection threshold when the soft fault is small, which leads to the low sensitivity of ...

Detailed modelling and analysis of digital mho distance relay with single-pole operation
Acta Polytechnica, 2021 This paper introduces a methodology for modelling a digital admittance-type distance relay using PSCAD/EMTDC. The proposed distance relay was tested in a simulation of the Brazilian power grid with predetermined fault scenarios. The goal of this paper is

2003 European Control Conference (ECC), 2003 Monitoring large-scale systems is of fundamental importance in modern infrastructures. Many of these large-scale systems are complex interconnections of sub-components which interact by means of communication channels with limited bandwidth. Therefore the information must be encoded in order to be transmitted.
