Evolution of the electrical contact of dynamic pantograph–catenary system [PDF]

Journal of Modern Transportation, 2016
A good contact between the pantograph and catenary is critically important for the working reliability of electric trains, while the basic understanding on the electrical contact evolution during the pantograph–catenary system working is still ambiguous so far.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, Volume 11, Issue 3, Page 601-619, June 2026.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

The Generating Mechanism and Suppression Measure of the ‘Wheel‐Rail’ Rolling Arc for Electrified Trains

High Voltage, Volume 11, Issue 2, Page 370-384, April 2026.
ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system. An insulated

Modeling and Control of Rail Potential With Partial Backflow Obstruction in DC Metro Systems

IET Electrical Systems in Transportation, Volume 2026, Issue 1, 2026.
Running rails are employed as the reflux conductor in DC metro systems, whose longitudinal resistance and joint resistance usually increase with the operating years of the system. Subsequently, the partial backflow obstruction occurs, which will greatly increase rail potential (RP) and endanger the security of the metro line operation. In this paper, a

Dual‐Frequency Piezoelectric Vibration Energy Harvester for IoT‐Based Real‐Time Freight Train Health Monitoring in Mongolia

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study evaluates the potential of piezoelectric vibration energy harvesting to power IoT nodes for real‐time health monitoring of the Mongolian railway. Triaxial vibration data were collected at 500 Hz over a 400 km freight route under loaded and unloaded conditions using a custom ESP32‐S3 + MPU9250 system, and dominant frequencies were extracted ...

Optimal Control of Pantograph-Catenary System Based on Parametric Identification

Scientific Journal of Riga Technical University. Computer Sciences, 2011
This article continues research on the pantograph- catenary system started in the previous papers (1), (2). The main purpose of the study is to use a computer of high- speed train to optimize the pantograph-catenary system by reducing power consumption when basic parameters of pantograph and catenary (contact network) change over time randomly.

FCDM‐Net: A Feature‐Calibrated Dynamic Masking Network Based on Pre‐Trained Models for Few‐Shot Catenary Component Anomaly Detection

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel feature‐calibrated dynamic masking network (FCDM‐Net) for the unified few‐shot anomaly detection of catenary components. First, a lightweight residual adapter is integrated with a frozen visual encoder. Through a few‐shot fine‐tuning strategy, the general visual features are mapped to the specific manifold space of catenary ...

Active Power Filter‐Based Low‐Frequency Ripple Power Suppression of the DC‐Link in Railway Traction Systems

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article presents an active power filtering control method to suppress ripple power in the DC‐link of railway traction systems, including both the inherent second‐order ripple of single‐phase rectifiers and additional frequency ripples introduced by the pantograph–catenary arc.
