Abstract

The distribution system on ships usually uses an AC system, while in this study, the reconfiguration of the AC distribution system into DC will be carried out, this is a way to increase the efficiency of fuel use in ship diesel generators. By reconfiguring the distribution system, the influence of impedance on the AC current can be eliminated. But reconfiguring the distribution system has an additional component, namely the converter, so that it can increase harmonic distortion and total harmonic distortion (THD) in the ship’s electrical system. This harmonic improvement can affect the quality of the power flowed in the system because it changes the waveform to not perfectly sinusoidal, so that the ship’s electrical equipment can experience overheating which can reduce the performance of the ship’s electrical equipment. In this study, an analysis was carried out to determine the number of harmonics that occur when the ship uses a DC electricity distribution system. Harmonic disturbance analysis is simulated using computer software, considering the operational conditions of the ship. From the results of the DC distribution simulation, total harmonic distortion (THD) was obtained on the generator bus and got the average of each condition are at 7.30% on the generator bus. Based on IEEE 519-2014 standard, the limit of total harmonic distortion is 8%, so that the result of total harmonic distortion is less than to the specified limit standard, but the results of Individual Harmonic Distortions (IHDs) are still exceeding the limit of IEEE 519-2014, which still above 5%. So, it is still necessary to find solution to reduce harmonic distortion that occurs.
