چکیده
In this paper, a novel DC bus voltage control strategy of the traction system is proposed for overhead line and energy storage device (ESD) hybrid railway vehicles. This realizes increase regenerative brake reduction consumed in powering by boosting motor voltage. When boost applied, separated from breaker, which generally equipped. paper proposes considering both breaker operation management onboard ESD. The static state calculated to reveal effect consumption ESD applying method. calculation results confirmed 10.1% 8.87% decrease total when was boosted 1950V single multiple travel between several stations, respectively. Moreover, method verified at 4 patterns A numerical simulation also performed verify dynamic characteristic, especially an overvoltage point view. As result, can be regulated without detecting overvoltage.
