提出了一种适用于架空线-储能装置（ESD）混合动力轨道车辆牵引系统的直流母线电压控制策略。该策略通过提高牵引电机电压，实现了再生制动能量的增加和供电能耗的降低。当应用直流母线电压升压时，牵引系统通过断路器与架空线路分开，断路器通常配备。本文提出了一种综合考虑断路器操作和能量管理的车载ESD策略。通过静态计算，揭示了应用所提出的控制方法降低能量消耗和ESD能量管理的效果。计算结果证实了10.1%和8.87%的总能耗下降时，直流母线电压提高到1950 V的单和多个站之间的旅行，分别。此外，所提出的能量管理方法进行了验证，在4种模式的直流母线电压。还进行了数值模拟，以验证的动态特性，特别是从过电压的角度来看。其结果是，能够不检测过电压地调整直流母线电压。
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 strategy realizes the increase of regenerative brake energy and reduction of consumed energy in the powering by boosting the traction motor voltage. When a DC bus voltage boost is applied, the traction system is separated from the overhead line by a breaker, which is generally equipped. This paper proposes a strategy considering both breaker operation and energy management of onboard ESD. The static state is calculated to reveal the effect of the reduction of energy consumption and the energy management of ESD by applying the proposed control method. The calculation results confirmed a 10.1% and 8.87% decrease in total energy consumption when the DC bus voltage was boosted to 1950V for single and multiple travel between several stations, respectively. Moreover, the proposed energy management method was verified at 4 patterns of the DC bus voltage. A numerical simulation was also performed to verify the dynamic characteristic, especially from an overvoltage point of view. As a result, the DC bus voltage can be regulated without detecting overvoltage.
