Problems solved by technology

However, it is necessary to add an additional frequency conversion power supply branch, which will increase the size and cost of the equipment. The control system of the frequency conversion power supply branch also needs to be configured separately, and the function of the charging and discharging device for the battery pack is complicated.

Embodiment 1

[0036] image 3 A circuit diagram of a ship power system powered by a hybrid power source in Embodiment 1.

[0037] Such as image 3 As shown, the ship power system powered by a hybrid power source includes: a power source 50, a first switch 17, a distribution board 10, a second switch 19, a battery branch 70, a third switch 21, a filter 29, a controllable reversible DC converter 25, drive circuit 60-1, discharge switch 28, load 11 and control and daily transformer branches.

[0038] The switchboard 10 controls and monitors the work of the main generator, and distributes the electric energy sent by the ship power or the shore power to the whole ship's electrical equipment through the main switchboard.

[0039] The power supply 50 supplies power to the switchboard 10 , including the shore power 3 and the main generating set 1 . The main generator set 1 is connected to the switchboard 10 through a first switch 17 . The shore power 3 is connected to the switchboard 10 through...

Abstract

The invention provides a marine electric power system capable of supplying power by a novel hybrid power source. The marine electric power system comprises a distribution panel, a power supply, a battery branch, a charging device, a charging switch, a chopping control type reversible converter connected with the distribution panel and at least one driving circuit, wherein the charging switch is switched on and a discharging switch is switched off when the power supply is used for supplying power; and when a storage battery is used for supplying power, the charging switch is switched off, and the discharging switch is switched on. The marine electric power system has the advantages that a storage battery power supply can be connected into the marine electric power system, so that a harbor generator is not needed, an independent variable-frequency power supply inversion branch is not needed, energy storage of the storage battery is increased, investment cost can be lowered besides space and weight, energy is saved, and habitation comfort is improved.

Description

technical field [0001] The invention relates to a ship power system powered by a hybrid power source. Background technique [0002] figure 1 Schematic diagram of the current mainstream electric propulsion ship power system. [0003] Such as figure 1 As shown, the power system of the whole ship is composed of a power supply, a switchboard 10 , a propulsion system, other marine loads 11 , and daily loads 13 . The power supply is composed of shore power 3 , main generating set 1 and mooring generator 2 ; the propulsion system is composed of phase-shifting transformer 4 , propulsion frequency converter, propulsion motor 7 and thruster 8 . The diode rectifier 5 and the inverter 6 constitute a propulsion frequency converter. [0004] The power supply supplies power to the whole ship's power distribution system 10, and the switchboard 10 uniformly deploys the whole ship's power according to the working conditions of the ship. [0005] Sailing working condition: the shore power...
