An icebreaker ship having voltage ride through capabilities, comprising: an emergency power supply (101), an electric lubricating oil pump (103), a first uninterruptible power supply UPS (102), a first cooling system (105), a second uninterruptible power supply UPS (104), a second cooling system (107), a third uninterruptible power supply UPS (106), a lifting system (109), a fourth uninterruptible power supply UPS (108), and a plurality of storage batteries (110). By means of providing a UPS for ancillary equipment that may lead a propeller to lose power and auxiliary equipment of the ancillary equipment respectively, the ancillary equipment and the auxiliary equipment thereof are prevented from working abnormally when voltage fluctuates, and local abnormalities are prevented from affecting the normal operation of the propeller by means of the butterfly effect. During the process of voltage sag, power is switched from being supplied by the main power supply to being supplied by the storage batteries, which solves the problem wherein a propeller cannot maintain a stable working state due to fluctuations in a main power grid on the ship, and attains the effect of power generation equipment and power equipment working steadily.
