The potential for electrical energy produced by wind turbines on ships is quite good because the electrical energy produced by wind turbines gets a source of turbine movement from free wind energy in nature and the reaction force from the speed of the ship, the faster the wind speed or the ship, the faster the turbine rotates that contribute more power. This paper aims to model a DC distribution system for wind turbines on a trimaran ship using and simulate the generated electrical potential. The method used is by modelling a wind turbine with power simulation software where there are two inputs needed, namely the wind speed that hits the wind turbine blade and the pitch angle ratio of the wind turbine blade. The output from the turbine generator in the form of AC voltage is converted into DC voltage through a 3-phase rectifier. After that, three simulation scenarios were carried out: a no-load simulation, an induction-load simulation, and a battery charging simulation. In the no-load simulation, the three-phase voltage generated by the induction generator is 692 Volt AC. It was once aligned. The resulting DC voltage profile still has ripples with a maximum amplitude of 692 DC volts. In the load simulation, there are 6 (six) wind turbines installed on board. Each wind turbine has a maximum power capacity of 100 kW. So that the total power generated by the turbine is 360 kW with a voltage of 690 V AC or only reaches 60% of the power capacity. For battery charging simulation, 1 (one) battery panel consisting of 19 batteries arranged in series has a voltage of 684 Volt DC with a capacity of 450 AH that takes 2831 seconds or 47.1 minutes.
