Power Quality Considerations for Microgrids Integrating Pairs of Mechanically Coupled Electrical Machines Driven by Power Converters

Microgrids integrating distributed motor-generator units are commonplace in locomotive and industrial applications. The behavior of these systems is dependent upon various design-operating parameters. However there is a distinct relation between power quality and power flow within these units. This paper presents an analysis of power quality measurements, depicting this interdependence. Respective results can be taken under consideration during power flow programming, enabling enhanced system operation.
