Abstract
A starting apparatus is disclosed for at least two synchronous machines, which starting apparatus includes an exciter unit which is provided for each synchronous machine and is associated with the respective synchronous machine. Each exciter unit can be connected to the field winding of the associated synchronous machine. A superordinate control unit is provided, with the superordinate control unit being connected via a communication link to each exciter unit. Furthermore, the starting apparatus includes at least one stator feed unit and at least one switching device, which is provided for each stator feed unit and is associated with the respective stator feed unit, in which case the respective switching device can be connected to the associated stator feed unit, the respective switching device can be connected to at least one synchronous machine, and the switching devices can be connected to one another when there are a plurality of switching devices. The exciter units can be connected to one another via a ring communication link. Each stator feed unit can be connected to the ring communication link. Each stator feed unit can also be connected via a communication link to an associated switching device, and exciter units which are associated with the stator feed units can be each connected via a communication link to a switching device.
