Problems solved by technology

However, since the rated power of the generator is set according to the required power at the time of entering and leaving the port, during normal navigation, the two generators are operated at a low load (for example, 60% of the rated output), and there is a risk of fuel deterioration. The problem of consumption efficiency

Abstract

This power generation system for ships comprises: a plurality of generators (11, 12, 13) that supply power to the interior of a ship; a secondary battery 14 which stores the power output from the plurality of generators (11, 12, 13) and supplies the stored power to the interior of the ship; and a control device 20 that supplies the power to the ship using the first generator 11 among the pluralityof generators (11, 12, 13) and the secondary battery 14 during normal operation of the ship. The control device 20 charges the secondary battery 14 so as to enable output of power equivalent to thatof the first generator 11 during inward / outward clearance of the ship.

Description

technical field [0001] The invention relates to a power generation system of a ship. Background technique [0002] In ships such as ferries, multiple (for example, three) generators are mounted in order to supply power to inboard equipment in consideration of redundancy or the maximum power required, and each generator is operated so that the running time becomes equal . For example, when entering and leaving a port, it is necessary to use the maximum power when using equipment such as propeller propellers. In this case, three generators are running at high load. On the other hand, during normal navigation, power is supplied to the inside of the ship by two generators and the remaining one is kept on standby. [0003] Generally, the generator is designed to have the best fuel consumption efficiency at the rated output, so there will be no problem in fuel consumption efficiency when entering and leaving the port. However, since the rated power of the generator is set acco...
