Description
Technical Field
The invention belongs to the technical field of power supply, and particularly relates to a power supply system for inland river shore power facilities.
Background
At present, all main production operation machines on the port and dock use clean energy of commercial power, and the air quality of the port area is relatively good. However, all equipment, lighting and communication facilities and the like related to production or life on the ship still need to be kept powered when the ship enters a port, particularly during berthing, and the auxiliary power generator of the ship needs to be kept in a working state. The fuel supply efficiency of the ship is low and the loss is serious due to the influence of factors such as the ship scale, the equipment quality of the ship and the like. The electric energy generated by the ship auxiliary generator cannot be stored, so that a large amount of energy is consumed, and the energy is wasted greatly, and the environment is polluted.
The "shore power technology" refers to a technology for supplying power to a ship in a harbor by using a shore-side power source. During the ship berthing, the diesel generator on the ship is turned off and is powered by the power grid power supply at the shore side, so that the fuel oil consumption of the diesel generator is saved, and the fuel oil amount saved by the port berthing ship after the shore power connection is related to the ton level, the ship type and the berthing time of the ship. In general, the greater the tonnage of the vessel, the longer the berthing operation, and the more fuel is saved.
