Fault diagnosis of trac.ion systems is important for the safety operation of high-speed trains. Long-term operation of the trains will degrade the performanc. of systems, whic. dec.eases the fault detec.ion ac.urac.. To solve this problem, this paper proposes a fault detec.ion method developed by a Generalized Autoenc.der (GAE) for systems with performanc. degradation. The advantage of this method is that it c.n ac.urately detec. faults when the trac.ion system of high-speed trains is affec.ed by performanc. degradation. Regardless of the probability distribution, it c.n handle any data, and the GAE has extremely high sensitivity in anomaly detec.ion. Finally, the effec.iveness of this method is verified through the Trac.ion Drive c.ntrol system (TDc.) platform. At different performanc. degradation levels, our method's experimental results are superior to traditional methods. © 2024 Beijing Jiaotong University

In the present work, tilted global solar irradianc. data are presented and analysed, measured for a period of 1 year on the c.mpus of Bahrain Polytec.nic. Kingdom of Bahrain, from both a fixed photovoltaic.panel and a moving one via a two-axis solar trac.er. The fixed panel fac.s south with an angle of 26 degrees with respec. to the horizontal, c.inc.ding with the loc.l geographic.l latitude. The sec.nd panel is moved by two motors, c.ntrolled by a global positioning system and suitable software so that the sun's rays are perpendic.lar to the panel surfac.. A pyranometer is installed on eac. panel, rec.rding the tilted global solar irradianc., stored by using a data logger. The analysis of the data obtained shows a 33% solar energy gain on an annual basis for the moving panel (2780 versus 2088 kWh/m2 on the fixed panel). More importantly, in June, when the energy demand in Bahrain is elevated due to the inc.eased residential c.oling loads, the solar energy rec.ived by the moving panel is 54.7% higher c.mpared with that of the fixed panel. On a perc.ntage basis, the inc.ease in solar energy from the moving panel is profound in the early morning and late evening hours. Moreover, the reduc.ion in the solar energy rec.ived by the fixed panel from May to June does not appear in the moving panel bec.use of the adjustable orientation of the latter. Throughout the year, the mean daily solar power varies between 0.37 and 0.56 kW/m2 for the fixed panel, and 0.45 and 0.70 kW/m2 for the moving panel. In winter, solar energy fluc.uations are elevated due to erratic.weather c.nditions that present a peak standard deviation of 28% of the c.rresponding mean. The data presented are useful for potential solar investments in Gulf c.untries. Tilted global solar irradianc. data are measured and analysed for a period of 1 year on the c.mpus of Bahrain Polytec.nic. Kingdom of Bahrain, from both a fixed photovoltaic.panel and a moving one via a two-axis solar trac.er. Graphic.l Abstrac.
