The utility model discloses a medium-frequency power supply system based on a high-voltage flexible direct-current power transmission line, which relates to the technical field of power generation and transmission of a power system, and is characterized in that electric energy generated by a power supply module is transmitted to the high-voltage direct-current power transmission line after being subjected to frequency conversion of a converter, transformation of a transformer, collection of a current collection line and commutation operation of an AC/DC converter station. The converter can convert the frequency of the electric energy transmitted by the power supply module into the intermediate frequency within the preset frequency range, so that the transformer connected with the converter can operate at the intermediate frequency and is intermediate frequency equipment; in addition, the AC/DC converter station can also operate the intermediate frequency and is an intermediate frequency subsystem, and the con
