[0034] The following disclosure provides many different implementation manners or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application.

[0035] The power supply system of a ship is used to transmit the power generated by a generator or the power stored in a battery to a propulsion motor and a load, so that the propulsion motor and the load can work normally.

[0036] However, during actual use, the harmonics in the power supply system may be coupled to other loads through the AC distribution board, interfering with precision equipment and affecting the reliability of the ship.

[0037] Specifically, all loads are powered by a single inverter and an AC distribution board. The harmonics output by the inverter will spread to all connected loads through the AC distribution board. At the same time, the harmonics generated by different loads during operation will also form a harmonic superposition effect.

[0038] Equipment such as communication equipment and navigation equipment in the ship will be affected by harmonics and cannot work properly.

[0039] To solve the technical problem that harmonics in the above power supply system are coupled to other loads through the AC distribution board, the present application provides a ship power supply system. Please refer to Figure 1 The ship power supply system includes a first power distribution component 100, a second power distribution component 200, and a load component 300. The first power distribution component 100 includes a DC busbar. The second power distribution component 200 includes a first inverter circuit 210 and a power distribution component 220. The first inverter circuit 210 is connected to the DC busbar, and the power distribution component 220 is connected to the first inverter circuit 210. The load component 300 includes a second inverter circuit 310 and a load component 320. The second inverter circuit 310 is connected to the DC busbar, and the load component 320 is connected to the second inverter circuit 310.

[0040] In some embodiments, the first inverter circuit 210 includes a first inverter 211, a first fuse 212, and a first switch 213. In some embodiments, the second inverter circuit 310 includes a second inverter 311, a second fuse 312, and a second switch 313.

[0041] Both the first inverter 211 and the second inverter 311 are used to convert direct current into alternating current for use by the power distribution component 220 and the load component 320.

[0042] The first switch 213 can disconnect the connection between the second power distribution component 200 and the first power distribution component 100. The second switch 313 can disconnect the connection between the first power distribution component 100 and the load component 300.

[0043] In some embodiments, the second power distribution component 200 further includes a transformer 230 connected between the first inverter circuit 210 and the power distribution component 220.

[0044] In some embodiments, the power distribution component 220 is an AC distribution board.

[0045] It can be understood that since the second power distribution component 220 and the load component 320 are respectively configured with independent first inverters 211 and second inverters 311, inverters with different specification parameters can be selected according to the electrical equipment connected to the second power distribution component 220 and the load characteristics of the load component 320, which can reduce the generation of harmonics.

[0046] In the above embodiments, by providing a second inverter circuit 310 independent of the ground inverter circuit for the load component 320, the load assembly 300 can be directly connected to the DC bus bar in the first power distribution assembly 100 independent of the second power distribution assembly 200. The harmonics generated in the second power distribution assembly 200 will only affect the link where the second power distribution assembly 200 is located, and the harmonics generated in the load assembly 300 will only affect the link where the load assembly 300 is located, avoiding harmonic superposition and mutual influence between different links, thereby improving the reliability of the power supply system. At the same time, the separately provided second power distribution assembly 200 and the load assembly 300 can also adjust the parameters in the inverter circuit according to the power consumption needs to achieve targeted settings, further reducing the possibility of harmonic generation, thereby improving the reliability of the power supply system.

[0057] In some embodiments, please refer to Figure 1 , the ship power supply system further includes a power component 400, and the power component 400 includes a first drive part 410, a second drive part 420, a third inverter circuit 450 and a fourth inverter circuit 460; the third inverter circuit 450 is connected to the first drive part 410 and the first DC busbar 110; the fourth inverter circuit 460 is connected to the second drive part 420 and the second DC busbar 120.

[0058] In some embodiments, the third inverter circuit 450 includes a sixth inverter 451, a sixth fuse 452, and a sixth switch 453. The sixth inverter 451 is connected between the first power distribution component 100 and the first driving part 410. The sixth fuse 452 is connected between the sixth inverter 451 and the first power distribution component 100. The sixth switch 453 is connected between the sixth fuse 452 and the first power distribution component 100.

[0059] In some embodiments, the fourth inverter circuit 460 includes a seventh inverter 461, a seventh fuse 462, and a seventh switch 463.

[0060] In some embodiments, both the first driving part 410 and the second driving part 420 are propulsion motors.

[0061] In the above embodiments, by providing at least two driving parts, namely the first driving part 410 and the second driving part 420 respectively, the risk of the ship losing power due to the damage of one driving part is reduced, and the reliability of the ship in use is improved. At the same time, two parts of the multiple driving parts are respectively connected to the first bus bar and the second bus bar connected by the circuit breaker 130, further reducing the risk of the ship losing power due to the simultaneous damage of the first driving part 410 and the second driving part 420, and improving the reliability of the ship in use.

[0062] In some embodiments, please refer to Figure 1 , the power assembly 400 further includes a rotor 430.

[0064] In some embodiments, both the first driving part 410 and the second driving part 420 can drive the rotor 430 to rotate respectively.

[0065] In the above embodiments, a rotor 430 that can be driven by both the first driving part 410 and the second driving part 420 is provided, which can still operate when one of the first driving part 410 and the second driving part 420 fails, and drives the propeller blade to rotate to provide power for the ship, reducing the risk of failure of the power assembly 400 when only one power assembly 400 is provided, and improving the reliability of the power supply system. At the same time, the first driving part 410 and the second driving part 420 are respectively connected to the first DC busbar 110 and the second DC busbar 120 separated by the circuit breaker 130, further reducing the possibility of simultaneous failure of the first driving part 410 and the second driving part 420, thereby further reducing the possibility of failure of the power assembly 400, and further improving the reliability of the power supply assembly.

[0066] In some embodiments, when at least one of the first driving part 410 and the second driving part 420 fails, the permanent magnet corresponding to the failed driving part can be removed, so as to avoid the generation of induced voltage when the rotating rotor 430 rotates relative to the failed driving part.

In addition, being disposed in the same housing 440 can also reduce the volume of the power assembly 400, so that the power assembly 400 can be disposed on a ship with a smaller volume.
