Abstract

The invention discloses an electric energy power system for a full electric propulsion ship. The system comprises two single-machine energy power systems and a direct-current contact box (C), wherein the two single-machine electric energy power systems share one energy storage battery (A); the energy storage battery (A) is connected with a first direct-current confluence busbar (B1) of the first single-machine energy power system in parallel; the positive pole of the first direct-current confluence busbar (B1) is connected with the input end of a direct-current contactor (C); the output end of the direct-current contactor (C) is connected with the positive pole of a second direct-current confluence busbar (B2) of the second single-machine energy power system; and the negative pole of the first direct-current confluence busbar (B1) is connected with the negative pole of the second direct-current confluence busbar (B2) to form a double-machine parallel system.

Description

technical field [0001] The invention relates to an electric propulsion system for an all-electric propulsion ship. Background technique [0002] The integrated electric propulsion system of a conventional all-electric propulsion ship includes a single-engine system and a double-engine parallel system, and its structure is as follows: figure 1 and figure 2 as shown, figure 1 and figure 2 Components such as the cooling system, sensors, battery monitoring system, etc. are not shown. [0003] figure 1 It is a schematic diagram of the structure of a conventional integrated electric propulsion system for a stand-alone system. The DC output of the diesel generator set is used for energy confluence in the DC busbar, and the energy is used by the rear-stage motor to drive the propeller system. This scheme belongs to the scheme of a single-machine serial hybrid power system, and the system structure is simple, but the reliability of the system is relatively poor. When a certain...
