| Summary: | With the increasing use of fossil fuels, there has been a significant negative
impact on the environment, prompting many to adopt renewable energy in various
sectors. Indonesia, as a maritime nation with the longest coastline in the world,
possesses abundant marine potential. However, many Indonesian fishermen still
rely on fossil fuels as their primary energy source for fishing activities. This paper
proposes a pollution-free 5 GT electric-powered fishing vessel as a more
environmentally friendly alternative. An induction motor is selected as the main
propulsion motor due to its reliability, cost-effectiveness, and durability. For
motor control, a constant V/f control with a proportional-integral (PI)
compensator is employed. The choice of constant V/f control with PI is based on
its ease of implementation and control techniques. Based on the analysis, it is
determined that a 50 HP electric motor is required as the main propulsion for a 5
GT fishing vessel. The maximum speed achievable by this electric vessel is 11
knots. The speed response of the induction motor shows an overshoot of 5%
during acceleration and 4% during deceleration. Under constant speed
conditions, the proposed motor control system is still able to maintain the vessel's
speed well when there are changes in load. |
