Problems solved by technology
However, due to the limited capacity and high price of lithium batteries, as well as the limited service life of lithium batteries, currently only sightseeing ships in inland waterways use pure electric mode, and it is impossible to use lithium batteries as the main power supply for ships on a large scale.
In addition, ships that use diesel generators as the main power supply have low power generation efficiency and long-term low-load conditions. The energy utilization rate is relatively low, the consumption rate is relatively high, and carbon emissions remain high, especially in some inland river scenic spots. is expressly prohibited from using

The embodiment of the invention discloses a gas-electric hybrid power ship energy management system and method. Through the system, a shore power supply device, a lithium battery power supply device and a gas generator power supply device are arranged, and the switching-on or switching-off states of a first switching-on and switching-off switch, a second switching-on and switching-off switch and a third switching-on and switching-off switch under different working conditions of a ship are controlled; the energy requirements of the shore power supply device and / or the lithium battery power supply device and / or the gas generator power supply device under the berthing working condition, the berthing working condition, the sailing working condition and the sailing working condition of the ship are met, and due to reasonable cooperation, the energy utilization rate can be increased while energy supply of the ship is ensured; and the gas generator power supply device is started to supply power only when the lithium battery has a first type of condition and a second type of condition under the ship navigation working condition and the ship navigation working condition, so that the carbon emission can be effectively reduced while the ship energy supply is ensured.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of ship control, and in particular to a gas-electric hybrid ship energy management system and method. Background technique [0002] At present, the electric propulsion system of hybrid ships basically adopts diesel generator sets to generate power, and the AC main grid distributes power, and cooperates with lithium batteries to generate power. However, due to the limited capacity and high price of lithium batteries, and the limited service life of lithium batteries, currently only sightseeing and tourist ships in inland waterways use pure electric mode, and it is impossible to use lithium batteries as the main power supply for ships on a large scale. In addition, ships that use diesel generators as the main power supply have low power generation efficiency and long-term low-load conditions. The energy utilization rate is relatively low, the consumption rate is relatively high, and c...
