    Fault Diagnosis of Induction Motors Using Recurrence Quantification Analysis and LSTM with Weighted BN by Dengyu Xiao, Yixiang Huang, Chengjin Qin, Haotian Shi, Yanming Li

    Published 2019-01-01
    “…To cover those shortcomings, in this paper, two manual feature learning approaches are embedded into a deep learning algorithm, and thus, a novel fault diagnosis framework is proposed for three-phase induction motors with a hybrid feature learning method, which combines empirical statistical parameters, recurrence quantification analysis (RQA) and long short-term memory (LSTM) neural network. …”

    Feasibility Analysis of Application of HX Series Electric Locomotive Under Ground Fault Mode by Yanmin ZHANG, Fengrong HAO, Guangxing TIAN, Ying FU, Baosheng SUN, Jianlong CHEN

    Published 2021-11-01
    “…Through simulation analysis,when a single-point ground fault occured on the motor side, the intermediate DC link side or x-terminal of the traction transformer secondary side, no matter which ground fault detection method, the fault converter can be isolated to meet the continuous power reduction operation of the locomotive without safety risk; When the grounding fault point occured at a-terminal on the secondary side of the traction transformer, there was still a risk for the continuation in low resistance grounding mode and in the operation of isolated fault converter,which shall be stopped for rescue; There was a risk for the operation of isolated grounding fault converter in high resistance grounding mode, and the continuous operation of fault shaft can be maintained. …”

    Estimation of shallow structure along the hinagu fault by applying seismic interferometry to DAS observations conducted along national route 3 in Kumamoto prefecture, Japan by Satoru Hamanaka, Kentaro Emoto

    Published 2024-11-01
    “…In this study, we recorded continuous ground motion for approximately 1 month using a 40 km-long fiber-optic communication cable running under National Route 3 in Kumamoto Prefecture, Japan. The cross-correlation function (CCF) was calculated using ambient noise, and three-station interferometry was applied to improve the signal-to-noise ratio of the CCF. …”
