Beschreibung
Zusammenfassung:	Embodiments of the present invention employ a closed loop controls philosophy, which actively controls the starting means (155) of a powerplant machine (100), throughout the start-up process. Here, the present invention may provide a method (500) for adjusting a nominal operating schedule (515) of the starting means (155), which may have the form of a Load Commutated Inverter (LCI) (155). Embodiments of the method (500) may adjust the nominal operating schedule based (515), in part, on an operating parameter (505), which is associated with the gas turbine 100. The operating parameter (505) may include, but is not limited to: a rotor speed, a desired start-up time, or the like. Here, the control system (150) may receive data on the operating parameter (505) associated with the gas turbine (100).
