The invention relates to a method for operating a rail vehicle (1), said rail vehicle (1) comprising:-a plurality of current collectors (3), each current collector (3) electrically connecting said rail vehicle (1) to an energy supply network (6); -a plurality of converters, comprising a first converter (11a) and a second converter (11b), each converter (11) being respectively associated with a specified one of the plurality of current collectors (3), and switching on and off a converter switch (25) repeatedly on and off on the basis of phase information about the phase position of the alternating voltage and/or phase current on the output side of the converter (11), and switching off the converter switch (25) on the basis of the phase position of the alternating voltage and/or phase current on the output side of the converter (11). Converting a direct current on the input side of the converter (11) into an alternating current on the output side of the converter (11); -an alternating current line (15) which electrically connects the output side of the converter (11), in which, when the rail vehicle (1) passes through a segment point of the energy supply network (6), the supply of energy from the energy supply network (6) to the input side of the first converter (11a) via a specified current collector (3) of the first converter (11a) is interrupted, a) detecting the interruption; b) stopping converting the direct current on the input side of the first converter (11a) into the alternating current on the output side of the first converter (11a); c) continuing to process the phase information about the phase position of the alternating voltage and/or the alternating current on the output side of the first converter (11a) during the interruption period; d) detecting a return of the energy supply of the energy supply network (6) to the input side of the first converter (11a); and e) the processing result of continuing to process the phase information during the interruption period is used to restart the conversion of the direct current on the input side of the first converter (11a) into the alternating current on the output side of the first converter (11a).
本发明涉及一种操作轨道车辆(1)的方法,所述轨道车辆(1)包括:‑多个集电器(3),每个集电器(3)将所述轨道车辆(1)与能量供应网络(6)电连接;‑多个转换器,包括第一转换器(11a)和第二转换器(11b),每个转换器(11)分别相应地被配属给所述多个集电器(3)中的指定的一个集电器(3),并根据关于所述转换器(11)的输出侧的交流电压和/或相电流的相位位置的相位信息,通过反复接通和切断转换器开关(25),将所述转换器(11)的输入侧的直流电流转换成所述转换器(11)的输出侧的交流电流;‑交流电线路(15),其将所述转换器(11)的输出侧电连接,其中,当所述轨道车辆(1)通过所述能量供应网络(6)的分段点时,使得从所述能量供应网络(6)通过所述第一转换器(11a)的指定的集电器(3)向所述第一转换器(11a)的输入侧的能量供应发生中断,a)检测所述中断;b)停止将所述第一转换器(11a)的输入侧的直流电流转换成所述第一转换器(11a)的输出侧的交流电流;c)在所述中断的时间段内继续处理关于所述第一转换器(11a)的输出侧的交流电压和/或交流电流的相位位置的相位信息;d)检测所述能量供应网络(6)向所述第一转换器(11a)的输入侧的能量供应的返回;以及e)在所述中断的时间段内继续处理相位信息的处理结果被用于重新启动将所述第一转换器(11a)的输入侧的直流电流转换成所述第一转换器(11a)的输出侧的交流电流。
