Identification and response strategy for pantograph-catenary contact loss in high-speed railway
Transient disconnection between pantographs and catenaries during train operation on electrified railways, known as pantograph-catenary contact loss, can cause issues like over-current, creating safety hazards and consequential disruptions to operational order. This paper introduces the main circuit...

| description | Transient disconnection between pantographs and catenaries during train operation on electrified railways, known as pantograph-catenary contact loss, can cause issues like over-current, creating safety hazards and consequential disruptions to operational order. This paper introduces the main circuit structure and control method of grid-side rectifiers of the prevailing traction electric drive systems for EMU. The analysis investigated the system impacts of pantograph-catenary contact loss, emphasizing the reasons for over-current occurrences during contact recovery, leading to the establishment of a rapid online identification method and a response strategy. Following developing a full-digital real-time simulation model of the electric drive systems for traction, which includes an arc model, accuracy verification was conducted firstly through waveform comparisons with actual measurements. This model was subsequently used to verify the proposed identification method and response strategy for pantograph-catenary contact loss. |
