System and method for power supply to electric ship by natural energy

Abstract

The invention provides a system and a method for supplying natural energy as power to an electric ship. The embodiment of the invention transforms solar energy and wind energy into electrical energy through a wind-light mixed power station, and is used by a wharf energy-adding station and used for charging a storage battery container hold of the electric ship; at the same time, the system is also connected with a commercial-power electric-fence; when the weather is fine in the daytime and the wind is heavy, the generated energy of the wind-light mixed power station is sufficient, the excess electric quantity can be merged into the commercial-power electric-fence for the use of other loads; when the weather is wet at night or in the daytime and the wind is light, the alternating current of the commercial-power electric-fence can be transformed into direct current so as to be used by the wharf energy-adding station and also used for charging the storage battery container hold of the electric ship; the wind-light mixed power station and the commercial-power electric-fence complement each other, so the natural energy supplied as power to the electric ship stably and reliably, the dependence on non-renewable energy resources such as petroleum, coals, etc. as well as the ship noise pollution can be reduced, energy crisis is relieved, and the atmosphere and the marine environment are protected.

Description

technical field [0001] The invention relates to the technical field of natural energy power generation applications, in particular to a system and method for using natural energy to supply energy to electric ships. Background technique [0002] Existing electric ships generally use a motor plus a transmission to drive the propeller to drive the ship. The electric energy required by the motor is provided by a battery placed on the ship, and the electric energy stored in the battery comes from the mains grid. When the electric ship can dock at the dock, if it needs to be charged, it only needs to charge the battery directly with the cable. [0003] We all know that the global energy shortage is getting worse. How to use natural energy to power the batteries of electric ships to reduce the dependence of electric ships on non-renewable energy such as oil and coal, alleviate the energy crisis, and protect the atmosphere and marine environment is an urgent problem to be solved. ...
