A few remarks about assessment methods of electric power quality on ships – Present state and further development

Abstract This paper concerns the problem of reliable assessment of a power quality in naval networks. Two aspects of the problem were discussed. Firstly, the parameters for electric power quality assessment and their permissible levels were presented. Further, the methods of their measurement were analyzed. Especially the critical analysis of relevant IEC standards was presented and proposals for their amendment were laid. These considerations were based on the results of the original author’s research carried out in ship electrical power systems for a few years. Finally, the original and complete methods of signal processing and basic features of newly constructed instrumentation for power quality assessment were shown. Presented paper is a continuation and in some respect the synthesis of the earlier works prepared by the same author completed by new contribution.
