Comparative Analysis of Reliability Indicators in Conventional and Hybrid SAVe cube Ship Electrical Power Systems

The hybrid SAVe CUBE devices are one of the most prospective topologies in marine power systems. The use of the AC-DC-AC architecture concept is related to limiting the spread of higher voltage and current harmonics in the ship's power supply system caused by the powerful electronic converters. This is associated with an increased number of elements, which also changes the overall reliability indicators. The report presents a comparative analysis of reliability indicators in conventional and hybrid marine power systems. The results can be used as quantitative criteria for evaluating the probability of failures, the overall reliability of the system, defining the repair cycle periods, which will facilitate the operational maintenance of ships electrical power systems.
