Real-Time Location-Aware Demand-Shaping for Power-Constrained AC Railway Corridors

Marton Laszlo Ambrus, Xiao Liu, Stuart Hillmansen, Zhongbei Tian

Power-constrained 25kV AC railway sections, particularly under degraded feeding, are protected today by blunt, section-wide power limits that penalise every train irrespective of whether it contributes to the binding condition. This paper presents a real-time, location-aware cont…

Estimating Available Traction Power in Multi-Train AC Railway Networks from a Distance-Dependent Power Envelope

Marton Laszlo Ambrus, Xiao Liu, Stuart Hillmansen, Zhongbei Tian

Decarbonisation is raising the electrical load on mainline alternating-current railway feeders that were not designed for sustained, simultaneous high-power demand. When several trains accelerate together on a shared feeder, the contact-line voltage can fall far enough to trigger…
