The invention relates to a circuit for enabling a current converter to be connected to a flexible direct-current power distribution network in an interference-free mode and belongs to the technical field of management of power grids. According to the circuit for enabling the current converter to be connected to the flexible direct-current power distribution network in the interference-free mode, the current converter is connected to a power gird in the interference-free mode through cooperation of a charging resistor and bypass disconnecting links, and the requirement of the flexible direct-current power distribution network system for flexible connection/disconnection of a direct-current power distribution unit is met. The charging current is limited through a current-limiting resistor so that a direct-current-side shunt capacitor of the current converter can be charged from the direct-current side; meanwhile, the bypass disconnecting links are connected to the two ends of the current-limiting resistor in parallel so that the normally running current can be conducted. The circuit for enabling the current converter to be connected to the flexible direct-current power distribution system in the interference-free mode has the advantages of being reliable in operation, easy to obtain, excellent in performance and can be widely applied to actual projects of flexible direct-current power distribution network systems.
