Abstract

The invention discloses a ship power and shore power conversion control device, and the device comprises: a shore power controller, which is connected with a shore power switch, and is used for controlling the on-off of the shore power switch, so as to enable a shore power system to provide shore power for a ship load; a ship electricity controller, which is respectively connected with the berthing generator set and the berthing switch group, and is used for controlling the rotating speed of the berthing generator set and the opening and closing of the berthing switch group, so that the berthing generator set provides ship electricity for the ship load; and a conversion controller, which is respectively connected with the shore power controller and the ship power controller and is used for converting the power supply of the ship load between the ship power and the shore power. The power supply of a ship load can be converted between ship power and shore power under the condition of no power loss, and the ship power and shore power conversion control device has the advantages of being low in cost, small in overall size and convenient to wire, debug and maintain.

Description

technical field [0001] The invention relates to the technical field of ship shore power conversion, in particular to a ship power and shore power conversion control device. Background technique [0002] With the increasing size of ships, the low-voltage berthing generator sets gradually cannot meet the power demand of ships when they are berthing. At present, when a ship berths at a port, the medium and high voltage units are mostly used to supply power to the ship's load through a transformer or directly from the shore power to the ship's load. As a clean energy source, shore power can prevent ships from generating carbon emissions and reduce pollution when they are berthing; The conversion control between electricity can reduce the economic cost of conversion control. Contents of the invention [0003] The object of the present invention is to provide a ship power and shore power conversion control device, so as to convert the power supply of the ship load between ship...
