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

EMUs Pantograph Aerodynamics Experimental Research in Dropping Status under Strong Wind Condition
机车电传动, 2016 When EMUs run at a high speed, the pantograph would be affected by airflow and blown up in dropping status, which would result in catenary short-circuit fault. In order to evaluate the pantograph aerodynamics characteristics in dropping status and ensure
