FIELD: transport.
SUBSTANCE: invention relates to AC electric drive for self-sustained object. Proposed system comprises variable-rpm ICE, AC generator, frequency converter and AC traction drive, all connected in series. Frequency converter is connected to AC generator output. ICE optimum rpm setting device is connected to ICE. Load power computation unit is connected to ICE optimum rpm setting device. Voltage stabiliser units are connected to frequency converters. Frequency converter voltage amplitude stabiliser is connected with the output of AC traction drive rpm setting device. AC traction drive rpm stabiliser output is connected traction drive rpm setting device output. Output voltage frequency generator is connected to frequency converter input.
EFFECT: reduced fuel consumption, stabilised AC amplitude and frequency, or stabilised constant voltage.
