WebJul 26, 2014 · Abstract: A capability curve reflects the maximum active and reactive power that a synchronous generator can deliver at its terminals. For a typical power station, the maximum generating power is given by the aggregate of the individual capability curve for each generator. WebThis assumes a “box” -type reactive capability range. FERC should clarify this using a reactive capability diagram for non-synchronous generation plant, as s measured at the Point of Interconnection (POI). In addition to the reactive capability curve, a complete specification should address the expected capabilities during offnominal voltages.-
