The utility model relates to a shorebased frequency conversion power-supply system of a port, which comprises a frequency conversion power source, a port high voltage transformer substation and a ship electric power system. The input end of the frequency conversion power source is connected with the port high voltage transformer substation, and the output end of the frequency conversion power source is connected with the ship electric power system. The power-supply system can continuously output three-phase alternating current in a voltage adjusting range of 0-6.6 KV or 0-10 KV and a frequency adjusting range of 0-60 Hz. An output side of the frequency conversion power source is connected with a distribution line through a cable drum, a high voltage output conducts power distribution of the ship electric power system directly through the distribution line, and a low voltage output conducts the power distribution of the ship electric power system after passing through a reduction transformer. The shorebased fr
