Electric propulsion systems for modern civil and military ships, as well as the growing number of electric consumers on board, are a topical issue in terms of onboard electric power quality. In this respect, a growing number of high power static converters are used, which inevitably leads to the appearance, in the electricity distribution network, of voltage and current harmonics with very high weights. Through this work, the authors made a study of these harmonics for two classical cases encountered aboard a ship, namely a nonlinear consumer and a consumer powered by a static six-pulse converter. Also, the highlight of these harmonics has been made in both shore and onboard power supplies. As a result of these measurements, some conclusions were drawn regarding the analyzed situations.
