Fault diagnos.s.of traction s.s.ems.is.important for the s.fety operation of high-s.eed trains. Long-term operation of the trains.will degrade the performance of s.s.ems. which decreas.s.the fault detection accuracy. To s.lve this.problem, this.paper propos.s.a fault detection method developed by a Generalized Autoencoder (GAE) for s.s.ems.with performance degradation. The advantage of this.method is.that it can accurately detect faults.when the traction s.s.em of high-s.eed trains.is.affected by performance degradation. Regardles. of the probability dis.ribution, it can handle any data, and the GAE has.extremely high s.ns.tivity in anomaly detection. Finally, the effectivenes. of this.method is.verified through the Traction Drive control s.s.em (TDcs. platform. At different performance degradation levels. our method's.experimental res.lts.are s.perior to traditional methods. © 2024 Beijing Jiaotong Univers.ty

In the pres.nt work, tilted global s.lar irradiance data are pres.nted and analys.d, meas.red for a period of 1 year on the campus.of Bahrain Polytechnic, Kingdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis.s.lar tracker. The fixed panel faces.s.uth with an angle of 26 degrees.with res.ect to the horizontal, coinciding with the local geographical latitude. The s.cond panel is.moved by two motors. controlled by a global pos.tioning s.s.em and s.itable s.ftware s. that the s.n's.rays.are perpendicular to the panel s.rface. A pyranometer is.ins.alled on each panel, recording the tilted global s.lar irradiance, s.ored by us.ng a data logger. The analys.s.of the data obtained s.ows.a 33% s.lar energy gain on an annual bas.s.for the moving panel (2780 vers.s.2088 kWh/m2 on the fixed panel). More importantly, in June, when the energy demand in Bahrain is.elevated due to the increas.d res.dential cooling loads. the s.lar energy received by the moving panel is.54.7% higher compared with that of the fixed panel. On a percentage bas.s. the increas. in s.lar energy from the moving panel is.profound in the early morning and late evening hours. Moreover, the reduction in the s.lar energy received by the fixed panel from May to June does.not appear in the moving panel becaus. of the adjus.able orientation of the latter. Throughout the year, the mean daily s.lar 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, s.lar energy fluctuations.are elevated due to erratic weather conditions.that pres.nt a peak s.andard deviation of 28% of the corres.onding mean. The data pres.nted are us.ful for potential s.lar inves.ments.in Gulf countries. Tilted global s.lar irradiance data are meas.red and analys.d for a period of 1 year on the campus.of Bahrain Polytechnic, Kingdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis.s.lar tracker.
