Abstract
A power distribution system is described. The system includes a main ac busbar and an emergency ac busbar. A hybrid drive system includes an induction electrical machine and a prime mover, the rotor of the electrical machine and the driving end of the prime mover being mechanically coupled to a load by means of a mechanical linkage such as a gearbox. The system includes a first active rectifier/inverter having ac input terminals electrically connected to the main ac busbar, and dc output terminals. The system includes a second active rectifier/inverter having dc input terminals electrically connected to the dc output of the first active rectifier/inverter by a dc link, and ac output terminals electrically connected to the induction electrical machine. A blackout restart system includes a rectifier having ac input terminals selectively electrically connectable to the emergency ac busbar and dc output terminals selectively electrically connectable to the dc link.
