摘要： PROBLEM TO BE SOLVED: To prevent over-discharge of an electric energy storage means during a power running operation or overcharge of the electric energy storage means during a regeneration operation.SOLUTION: In a drive control device for a railway vehicle, in which a regeneration braking force is increased by increasing a voltage to be applied to an inverter device by adding an output voltage of a voltage adjustment means to a DC power supply voltage (overhead wire voltage), an operation of a current control means is started prior to the start of a power running operation or a regeneration operation of the inverter device, and the operation of the current control means is stopped later than the stopping of the power running operation or the regeneration operation of the inverter device when the inverter device stops the power running operation or the regeneration operation. Thereby, the current control means is surely operated at least during the operation period of the inverter device, so that the output voltage (current flowing through the electric energy storage means) of the voltage adjustment means is adjusted by the current control means, to thereby prevent the over-discharge during power running operation or the overcharge during regeneration operation.

摘要： PROBLEM TO BE SOLVED: To provide a simple and easy control system for an electric diesel railcar with high control stability, switching a power supply source of an auxiliary power supply device from an inverter device (regeneration brake) to a converter device (engine-generated electric power).SOLUTION: When regeneration brake electric power is likely to exceed auxiliary electric power consumption, a DC part voltage is pushed up by the regeneration brake electric power, and the pushed-up DC part voltage reaches an upper limit voltage limit. Upper limit voltage limit control is thereby started, and an inverter torque command value is suppressed so that the DC part voltage does not exceed the upper limit voltage limit value. With the decrease in speed by braking, the regeneration brake electric power becomes equal to the auxiliary electric power consumption, and becomes lower than the auxiliary electric power consumption upon further deceleration. The DC part voltage becomes lower than the upper limit voltage limit, and when the upper limit voltage limit control is accordingly stopped, the DC part voltage is lowered to a lower limit voltage limit. A converter torque command value is adjusted so that the DC part voltage is not lower than the lower limit voltage limit value.
摘要翻译：要解决的问题：为了提供具有高控制稳定性的电动柴油轨道车的简单易用的控制系统，将辅助电源装置的电源从逆变器装置（再生制动）切换到转换器装置（发动机产生的电力）。解决方案：当再生制动电力可能超过辅助电力消耗时，通过再生制动电力将直流部分电压向上推，并且上推直流部分电压达到上限电压极限。由此开始上限电压限制控制，并且抑制逆变器转矩指令值，使得DC部分电压不超过上限电压限制值。随着制动速度的降低，再生制动电力等于辅助电力消耗，并且在进一步减速时变得低于辅助电力消耗。直流部分电压变得低于上限电压限制，并且当相应地停止上限电压限制控制时，直流部分电压降低到下限电压极限。 A转换器转矩指令值被调整为使得DC部分电压不低于下限电压限制值。
