The invention relates to an intelligent
shore power
system which comprises a variable-frequency power source, a switching network and an electric reactor. The variable-frequency power source comprises a rectifying module, an inversion module, a
bus, a variable-frequency power source controller, a communication module and a
power grid sampling module, wherein the rectifying module, the
bus, the inversion module, the variable-frequency power source controller, the
power grid sampling module, the switching network and the electric reactor are sequentially connected; the
power grid sampling module obtains external ship power grid information in real time and transmits the external ship power grid information to the variable-frequency power source controller, the variable-frequency power source controller controls the switching network to switch power grid systems to be matched with a ship power grid according to the external ship power grid information, and
shore power grid information is generated; when the external ship power grid information and the
shore power grid information are the same, the variable-frequency power source controller controls the inversion module to be connected with the electric reactor, and after
voltage is stabilized, the variable-frequency power source controller controls disconnection of an external marine auxiliary
machine and the ship power grid through the communication module.
