Ship emergency power source system based on solar power generation

Abstract

The invention provides a ship emergency power source system based on solar power generation. According to the system, under good light conditions, a lithium battery pack is charged through a solar power generation device and inverted through a two-way photovoltaic inverter after being fully charged, and then the lithium battery pack is connected into a ship main electric network on a ship emergency switchboard (2); when the light conditions are poor or the solar power generation device fails, the ship main electric network is rectified through the two-way photovoltaic inverter and then used for charging the lithium battery pack to ensure the reliability of the lithium battery pack serving as a ship emergency power source; when the ship main electric network is powered off, failure of the ship main electric network is automatically detected through the system, and the emergency power source supplies electricity to emergency loads through the ship emergency switchboard to achieve energy conservation and emission reduction. While solar energy (clean energy) is used sufficiently, voltage stabilization and energy storage functions of lithium ion batteries in the system are brought into play, and not only are fuel consumption and exhaust emission reduced, but also a diesel oil emergency power generation unit can be replaced.

Description

technical field [0001] The invention relates to the technical field of application of solar power generation in ships, in particular to a solar energy-powered emergency power supply applied to ships, which belongs to the fields of new energy applications and green energy for ships. Background technique [0002] Since the oil crisis in the 1970s, fuel prices have been rising, and the proportion of fuel costs in ship operating expenses has increased from more than a dozen percent to 30 to 40 percent. The rapid growth of fuel consumption not only causes a large amount of capital consumption, but also the tail gas emitted has great pollution to the environment and is the direct source of the greenhouse effect. The traditional ship emergency power supply is mainly divided into emergency generators and emergency battery packs, both of which consume diesel to provide electricity. Under the premise of not changing the original ship power grid structure, the invention aims to use gr...

Problems solved by technology

Due to the limited power generation capacity of solar photovoltaic systems, the traditional solar energy application ideas on ships are relatively single. For large ships, solar power generation systems can only be used as auxiliary propulsion power or domestic power consumption.
