Abstract

The invention relates to the field of ships, and discloses a ship shore power rapid connection and dynamic load matching optimization system, which comprises a rapid connection sub-module, a dynamic load matching optimization sub-module, a dynamic load matching optimization sub-module, a dynamic load matching optimization sub-module, a dynamic load matching optimization sub-module and a dynamic load matching optimization sub-module, the position of the plug is determined through the triangular positioning principle of the wharf side laser transmitter and the shipborne infrared receiver; the dynamic monitoring sub-module is connected with the quick connection sub-module, is provided with an electric energy quality sensor for acquiring the voltage of a ship main distribution board, and realizes full-automatic butt joint of a plug and a socket within 18-20 seconds through the triangular positioning principle of an infrared transmitting and receiving unit and slope current control of an electromagnetic locking mechanism; compared with traditional manual operation, the efficiency is improved by more than 80%. The ship berthing deviation can be actively compensated through the magnetic attraction guiding design, the problem of poor contact of manual butt joint is avoided through cooperation with double detection of the pressure sensor and the contact resistor, and stable connection in the stormy wave environment is adapted.
