Power quality analysis for the highly-electric asset with DC power distribution

The purpose of this work is to highlight the major power quality issues that arise from the prevalence of power electronic converters in an Integrated Power System (IPS) of an asset with Medium Voltage Direct Current (MVDC) distribution.

In the first part of the paper the indexes of power quality for shipboard power systems, as defined from classification societies and military standards, are discussed. In the second part, the asset’s electrical grid is modeled and a detailed power quality assessment is performed. Finally, the analysis results are validated through detailed simulation.
