Abstract:Research purposes:Zheng zhou-Xi'an Passenger Dedicated Line is one of the 350km/h passenger dedicated lines in China. If the 10kV continuous power transmission line of underground cable is used, the reliability of the power supply will be enhanced much, but at the same time, the ground capacitance current and phase capacitance current of the cable power line will be increased. To these problems this paper gives solutions by studying.
Research conclusions:For the increases of ground capacitance current and phase capacitance current of cable power line, three-phase compensation reactors are installed in the appropriate place along railway line and the neutral grounding system with low resistance is used for the grounding of power system in order to compensate capacitance current.
