Problems solved by technology

However, since the frequency of power consumption by ships is different in each country, if the frequency of the port power grid is different from that of the ship, the ship will not be able to use the power provided by the port.

Abstract

The invention relates to a ship shore power system respectively connected with a ship and a power grid. The ship shore power system comprises a distribution portion connected with the power grid and used for receiving the voltage of the power grid from the power grid and performing reactive power compensation and harmonic management of the power grid; and a transformation portion connected with the distribution portion and used for receiving the voltage of the power grid from the distribution portion and performing transformation and/or frequency conversion of the voltage of the power grid, and when the transformation portion is connected with the ship, the transformation portion supplies the conversion voltage after transformation and/or frequency conversion to the ship. No matter the frequency of a power supply system of the docking ship is 50 Hz or not 50 Hz, the ship shore power system can be connected with the power supply system of the ship, and the power consumption of the ship is satisfied. Besides, the ship shore power system can also perform reactive power compensation and harmonic management of the power grid so that an electric power system of the power grid does not generate harmonic pollution.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a ship shore power system. Background technique [0002] In the past, ships berthing at the port had to use ship auxiliary engines to generate electricity 24 hours a day to meet the ship's electricity demand. However, the auxiliary engine burns a large amount of oil during work, emits a large amount of exhaust gas, and generates noise pollution 24 hours a day. [0003] In order to solve this problem, the ship can be connected to the port grid, and the shore power system can be used to supply power to the ship docked at the dock. However, since the frequency of power consumption of ships varies from country to country, the ship will not be able to use the power provided by the port if the frequency of the port power grid is different from the frequency of power consumption of the ship. Contents of the invention [0004] technical problem [0005] In view of this, the technic...
