In three-phase power systems, transformers with wye-connected windings on one side and delta-connected windings on the other are commonplace, as are three-winding transformers with a combination of wye and delta-connected windings. Such connections introduce phases shifts with multiples of 30°. In a standard (positive sequence) power flow these phase shifts need not be modeled; however, […]

The “Region” data structure, introduced with PowerWorld Simulator version 24, provides a way to group power system elements by geographic regions. A Region is defined as a polygon with latitude and longitude coordinates of its vertices. Regions may be loaded from shapefiles or auxiliary (*.aux) files, or defined graphically in PowerWorld Simulator. They may also […]

Beginning with version 24, PowerWorld Simulator’s GIC add-on is integrated with the Electric Power Research Institute’s (EPRI) GICHarm tool. The latter performs harmonic analysis on grid connected devices such as capacitor banks to determine if expected geomagnetic induced currents (GICs) could cause them to trip. This integration enables an iterative analysis, summarized by: Using an […]
