Research of simulation and experiment on arc characteristics of gas mechanical switch
High Voltage, Volume 9, Issue 3, Page 626-635, June 2024.Abstract An arc is the high‐temperature discharge plasma produced in the opening process of mechanical switches, which directly affects the breaking capability of a hybrid DC circuit breaker. According to the physical mechanism of an electric arc, the construction of an arc model for simulation analysis is an important technical means in the electrical

Fuzzy Integral Based Multi-Sensor Fusion for Arc Detection in the Pantograph-Catenary System [PDF]
, 2018 The pantograph-catenary subsystem is a fundamental component of a railway train since it provides the traction electrical power. A bad operating condition or, even worse, a failure can disrupt the railway traffic creating economic damages and, in some ...

Cluster Analysis Based Arc Detection in Pantograph-Catenary System [PDF]
Journal of Advanced Transportation, 2018 The pantograph-catenary system, which ensures the transmission of electrical energy, is a critical component of a high-speed electric multiple unit (EMU) train. The pantograph-catenary arc directly affects the power supply quality. The Chinese Railway High-speed (CRH) is equipped with a 6C system to obtain pantograph videos. However, it is difficult to

On the role of time‐of‐use electricity price in charge scheduling for electric bus fleets
Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 8, Page 1218-1237, 15 April 2024.Abstract As electric buses become increasingly popular, it is imperative to optimize the schedules of electric buses with explicit consideration of their charging requirements. Unfortunately, existing studies failed to properly model the impacts of essential operating factors, including the time‐of‐use (TOU) electricity price, partial charging, and ...

Plant interaction networks reveal the limits of our understanding of diversity maintenance
Ecology Letters, Volume 27, Issue 2, February 2024.Current theories for understanding and predicting the maintenance of diversity in plant systems focus almost exclusively on competition. We describe plant–plant interaction networks in a diverse, empirical wildflower community co‐occurring under a range of environmental conditions.
