Ship power supplying system

Abstract

The invention discloses a ship power supplying system. The oil consumption of ships can be drastically reduced, the energy utilization rate is increased, the purpose of energy conservation and emission reduction is achieved, and the flexibility of the ship power supplying system is maintained. According to the technical scheme, the system comprises a ship power supplying battery which stores electric energy to power a ship, a power supplying battery monitoring module which is connected to the ship power supplying battery, and monitors and controls the charging and discharging processes of the ship power supplying battery, an inverting unit which is connected to the ship power supplying battery and a load, and converts direct current of the battery into an alternating current used for working of the load and a battery charging component which is connected to the ship power supplying battery and charges the ship power supplying battery.

Description

technical field [0001] The invention relates to a ship power supply technology, in particular to a system for using clean energy to supply power to ships. Background technique [0002] As the most important prime mover of the marine electric propulsion system, the problems of diesel engines are becoming more and more prominent: first, a large amount of concentrated nitrogen and sulfur produced during the combustion of shipping fuel has become the main factor of environmental pollution; second, high-speed, high-power diesel engines produce People pay more and more attention to the problems caused by vibration and noise. "Zero noise" is a higher requirement for people's living and working environment, especially for passengers and crew. Third, the increasingly prominent global energy issues require people to New energy sources and power devices must be developed in a short period of time. [0003] Moreover, all kinds of river cleaning boats, dredging boats, garbage boats, pil...

AI Technical Summary

Problems solved by technology

[0004] In addition to the problem of power energy, electric propulsion ships using diesel generators have always faced a technical problem: the impact of frequent load disturbances on the propulsion system

These load fluctuations have a huge impact on the ship's power grid and power station, reducing the stability of the ship, so that the internal combustion engine fuel in the power station cannot be fully burned, causing double damage to environmental and economic benefits

[0005] Therefore, traditional ships are usually driven by diesel engines, which have the problems of high energy consumption, high noise, and large exhaust gas pollution, which seriously affect the local environment and frequent load disturbances have a great impact on the ship's electric propulsion system.
