“…Second, it can provide an opportunity of distance analyses of the recorded video of arc disturbances and establish the cause of disturbances, identify the type of defect in order to decide on the manner and timing of its fixing. Third, it is expected to receive the documentary evidence of arc disturbances in a certain place as the video file [2].…”

1 -In many hub traction power supply systems (TPSS), the 27.5kV-busbars in the traction substation (TSS) have supplied several railway lines in a local area for reducing the number of TSSs. However, the multiple railway lines connected to the busbar may affect the resonance behaviors of the entire system. It's therefore needed to investigate the resonance behaviors under such hub TPSS conditions since the harmonic current collection of all railway lines will aggravate the resonance problem. Thus, resonance mode assessment and its sensitivity method is adopted for investigating the resonance behaviors of hub TPSS affected by different numbers of connected lines, lengths of supply lines, system capacities, etc. The numerical results of modal sensitivity indices are compared to investigate and quantify the harmonic resonance issue caused by multiple electrical railway lines. In addition, resonance frequency-shift technique and using modal impedance sensitivity index based method are also employed to mitigate the critical harmonic resonances. The results illustrate that it is effective to analyze resonance issues by adopting the harmonic model and modal methods in this paper. The two types of resonance behaviors (i.e. primary resonance and resonance band) caused from the hub TPSS have been fully investigated, and the resulted harmonic distortion of hub TPSS is suppressed.

“…This consumption is determined from the traction system power consumption, which is characterized by the active power consumption P L and the displacement power factor λ L [15]. [5], [6], [16] , [17], [19] Power System The usual values of the above parameters are in Table I. In railway traction systems, electric traction locomotives fed by adjustable speed drives are a source of harmonic currents I k [7], [9], [13], [16], [17], which distort traction system voltages and reduces power quality.…”

“…The harmonic problem is even greater in the presence of resonance in the overhead feeders of the traction circuit as it can increase harmonic voltage distortion. Many works have studied experimentally and numerically the resonance problem at traction system pantograph terminals [6], [7], [11], [16] − [19]. However, few consider external balancing equipment and represent the traction system by its equivalent impedance at the fundamental frequency obtained from its power demand [15].…”

AC traction systems are 1x25 or 2x25 kV/50 Hz single-phase, non-linear, time-varying loads that can cause power quality problems such as unbalanced or distorted voltages. To reduce unbalance, external balancing equipment is usually connected to these systems, forming the Steinmetz circuit. Parallel resonances can occur in this type of circuits, exciting the harmonic emissions (below 2 kHz) of railway adjustable speed drives. This paper studies these resonances at pantograph terminals and provides analytical expressions to determine their harmonic frequencies. The expressions are validated from several traction systems in the literature and PSCAD simulations.
