As many electric multiple units (EMUs) integrate into the traction network, low-frequency oscillation (LFO) issues may occur in railway systems. Impedance-based frequency-domain stability analysis is a common method used to analyze the stability of vehicle-grid systems. However, the vehicle-grid system is a complex single-phase system with numerous nonlinear components, making it difficult to esta...Show More
Pantograph–catenary systems are the key equipment for current conduction from power grids to electric locomotives, and within such a system, the property of the slide, especially the contact resistance ( $R_{j}$ ), directly affects its current collection performance. Compared to previous studies, this article focuses on the microscopic roughness parameters, which affects $R_{j}$ greatly. The cha...Show More
In the pantograph-catenary system, the change of the surface roughness of pantograph sliding plate directly affects the current collection quality of electric locomotive. In this paper, a large number of current-carrying friction experiments have been carried out on the self-developed high-performance sliding electric contact experimental machine, and the effects of the surface roughness of the sl...Show More
