Power quality on ships: Today and tomorrow's challenges

This paper deals with a problem of electrical power quality on ships, observed from today perspective and appointing tomorrow's challenges. Two basic aspects, assessment and improvement of power quality are taken into account. In the process of power quality assessment, the existing ambiguities are analyzed and discussed, after that the undertaken measures and challenges to overcome them are presented. The ways of improving of power quality on ships are described and analyzed into two layers: technological solutions and the staff competences. Expectations and challenges for the future based on developments of both, legal and professional aspects, are focused on the key question: how to reduce a risk of ship accidents. Theoretical considerations are aided by experimental results based mainly on the author's research team experience and achievements.
