FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used for power supply of AC electric load. Diesel generator plant comprises a diesel engine with variable speed of rotation, to which a synchronous generator with a rectifier is connected, as well as an autonomous inverter. Synchronous generator used is a synchronous generator with permanent magnets. Diesel engine is connected to a diesel engine shaft RPM transducer connected with an efficient speed of rotation setting unit. Parallel to the rectifier a filter, a converter and power sensor are connected. Data outputs of the power sensor are connected with the efficient speed of rotation setting unit and the accumulator battery charge and discharge control unit, which is connected to the converter connected with the accumulator battery. Efficient RPM setting unit is connected to a servo drive connected with the diesel engine. Electric outputs of the power sensor are connected to the autonomous inverter, which is connected to the AC electric load connected with voltage sensor connected to the inverter control unit connected with the autonomous inverter.
EFFECT: technical result is optimal control of power flows between the accumulator battery and the AC electric load in braking modes.
