摘要
The invention relates to a diesel-electric drive system comprising a permanently excited synchronous generator (4), which is mechanically coupled to a diesel motor (2) on the rotor side and has an electrical connection to a voltage link convertor (6) on the stator side, said converter having a respective self-commutated pulse-controlled converter (12, 14) on the generator and load sides. The converters are interconnected on the d.c. voltage side by means of a d.c.link (18). The system also comprises a braking resistor (20), which can be electrically connected to said d.c. link (18). According to the invention, each connection (R.S.T) of the pulse-controlled converter (12) in the voltage link converter (6) on the generator side can be electrically connected to a respective braking resistor (34,36,38) by means of an actuator (32), said connections being electrically interlinked. This permits the provision of a diesel-electric drive system that no longer requires an additional brake attenuator.
