Abstract

Synchronous machines (5) are employed for traction system tie frequency converters with hyposynchronous and hypersynchronous cascade sets for the purpose of transferring electrical energy in the range of 8 MW - 90 MW from a national grid (1) with 50 Hz or 60 Hz into a traction system (2) with 16 2 3 Hz or 25 Hz, and vice versa. In order to be able to run up a synchronous machine (5) connected to the traction system (2) without start-up auxiliary excitation from the national grid (1) when the residual magnetism is lacking or insufficient, the energy for the excitation of the synchronous machine (5) is taken from a battery (9) via a chopper (8). The battery (9) is charged via a choke (7) by a two-phase bridge- connected rectifier (6), which is connected to the stator winding of the synchronous machine (5) via a field-circuit transformer (T3). In the event of a short circuit (11) in the traction system (2), excitation of the synchronous machine (5) can be maintained until a protective circuit-breaker (S8) is opened via a protective tripping device. <IMAGE>
