Comprehensive ship power system

Abstract

The invention discloses a comprehensive ship power system including a fuel battery power generation subsystem, a lithium battery energy storage subsystem, a permanent magnet propulsion subsystem, a power distribution subsystem and an energy management subsystem, wherein the fuel battery power generation subsystem adopts a fuel battery pack as a main generator set, the lithium battery energy storage subsystem is configured to carry out energy buffering, and the lithium battery energy storage subsystem is composed of a lithium titanate battery units in series-parallel connection. The fuel battery pack converts chemical energy into direct-current electric energy, and provides electric energy for a propelling motor and a whole-boat auxiliary machine. The electric energy generated by the fuel battery power generation subsystem is transmitted to the lithium battery energy storage subsystem, the permanent magnet propulsion subsystem, auxiliary machines, weapons, detectors, and daily power consumption and other electric equipment. Energy monitoring and dispatching are realized through the energy management subsystem. The applicability of the system is improved, the high utilization of energy is achieved, and the acoustic concealing performance is improved.

Description

technical field [0001] The invention relates to a comprehensive power system for ships, which belongs to the field of power systems and is suitable for power systems of ships, submersibles, unmanned vehicles and deep sea space stations. Background technique [0002] The traditional ship propulsion system exists independently of the power system, and is usually directly propelled by a traditional heat engine or other mechanical device. In this system, the reduction gearbox becomes an important factor affecting the acoustic stealth performance, which is not conducive to the implementation of vibration and noise reduction measures. implement. Traditional submersibles use lead-acid batteries as the main power source, and use DC electric propulsion to reduce noise sources, and their power density and energy utilization efficiency need to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies ...
