The invention provides a traction power supply network terminal voltage stabilizing device and a traction power supply network stabilizing system. The traction power supply network tail end voltage stabilizing device comprises a voltage detection circuit, a control circuit and an alternating current power circuit, wherein the voltage detection circuit is used for detecting power supply voltage ata tail end of an uplink or downlink bus of the power supply network, the control circuit is electrically connected with the voltage detection circuit; the control circuit is used for receiving the power supply voltage; the alternating current power circuit is electrically connected with the control circuit; and the AC power circuit is used for outputting reactive power to a tail end of an uplink or downlink bus of the power supply network. And the control circuit is also used for controlling the reactive power outputted by the AC power circuit based on the power supply voltage and the target voltage, so the power supply voltage is stabilized at the target voltage.
