DIESEL-ELECTRIC DRIVE SYSTEM WITH SYNCHRONOUS GENERATOR EXCITED WITH CONSTANT MAGNETS Russian patent published in 2011 - IPC H02P3/22 B60L7/22 B60L11/08 

FIELD: electricity.

SUBSTANCE: in diesel-electric drive system the synchronous generator (4) excited with constant magnets is mechanically connected on rotor side to diesel engine (2) and on stator side to two-section valve-type voltage converter (6) which in the side of generator and load includes independent pulse valve-type converters of electric power (12, 14), which are connected on the side of constant voltage to each other by means of intermediate link of constant voltage (18) and to brake resistor (20), which is electrically conducting and connected to this intermediate link of constant voltage (18). As brake resistor there provided is multi-phase scheme of brake resistors, which by means of multi-phase switching device (32) is electrically connected in series to multi-phase system of stator winding (74) of synchronous generator (4) excited with constant magnets. As a result, in diesel-electric drive system the additional brake control is not required, and it is possible to switch between generator operating mode and braking mode, and rotation frequency of diesel engine can be set in braking mode.

EFFECT: design is simplified.
