APPLICATION OF SOME NEW POWER QUALITY INDICES IN ANALYSIS OF THE SHIPBOARD ELECTRICAL SYSTEM EFFICIENCY

Improving the quality of electricity and electromagnetic compatibility is a topical issue in shipboard electrical power systems as these concern two main technical aspects. First is to improve the electromagnetic compatibility, which leads to improvement of the operating modes of the equipment and thus increase of the overall reliability of the system. Second aspect is related to the quality of electricity leading both to increase in overall reliability and refinement of measures to reduce the power and energy losses.

The latter is particularly relevant, since it is directly related to saving primary energy sources - liquid fuels, and this in turn leads to reduction of greenhouse gas emissions. This paper focuses on the possibilities of using some new quality indicators of electricity and electromagnetic compatibility, which are not regulated by normative documents. Practical software application has been developed in MathCAD Prime 3.0 environment and its use is shown in experimental studies of cruise ship class 1A1.
