PROBLEM TO BE SOLVED: To achieve downsizing and weight saving while suppressing a harmonic in an intra-ship bus.SOLUTION: A ship power system 101 for driving propellers 36 and 38 of a ship includes: power generators 4a, 4b, and 4c that are connected to an intra-ship bus 2 and generate predetermined power; shaft driving units 8 and 10 that are connected to the intra-ship bus 2 and convert, by using inverters 28a and 28b and inverters 30a and 30b, power supplied from the power generators 4a, 4b, and 4c to predetermined AC power to drive the propellers 36 and 38; and a harmonic suppressor 60 that is singly connected to the intra-ship bus 2, is composed of AC reactors 64a, 64b, and 64c and power capacitors 66a, 66b, and 66c, and absorbs harmonics flowing out from the inverters 28a and 28b and the inverters 30a and 30b into the intra-ship bus 2.SELECTED DRAWING: Figure 1 |
