Stability Improvement of Electric Ship Propulsion System Using Supercapacitor

in this paper, the concepts of modelling, simulation, verification and validation are described in order to analyse their necessities in electric ship propulsion system simulation. Traditional verification and validation methods are outlined before a new method based on expert theory and verification and validation methods of software testing is proposed to verify if the simulation program meets customers needs and respective software protocols, according to the characteristics of electric ship propulsion system.

Diesel-electric ship propulsion is a frequent shipowners choice nowadays, especially on passengerships. Despite many diesel engines advantages, their primary disadvantage is emission of pollutants. As environmental standards become more stringent, the question of optimal alternative to diesel-electric propulsion arises. COGES (COmbined Gas turbine Electric and Steam) propulsion system is one of the proposals for alternative propulsion system, primarily due to significant reduction of pollutant emissions. On the other hand, gas turbines have higher specific fuel consumption in comparison with diesel engines what represents their noticeable disadvantage. However, some analyzes suggested that COGES propulsion system could be still cost-effective in comparison to diesel-electric propulsion, particularly on passenger ships where higher initial investment can be compensated by increasing the number of passenger cabins. This paper shows a comparison of above mentioned propulsion systems, which can be useful for the optimal ship propulsion system selection
