FIELD: electrical equipment.
SUBSTANCE: invention relates to the electrical equipment. Autonomous power supply system with combined energy storage includes two wind-driven electric plants, two current sensors, two maximum power take-off controllers, diesel generator unit, three controlled rectifiers, self-contained inverter, AC electric load, ballast load, ballast load regulator, supercapacitor battery connected directly to DC bus, and two storage batteries connected to DC bus through individual matching charge-discharge devices. First linear current sensor is installed on line connecting first wind electric plant to first rectifier, wherein the first linear current sensor is connected to the first controller, which is connected to the first rectifier. Second wind-driven electrical plant is connected to the second rectifier, besides, on the line connecting them the second linear current sensor is installed, which is connected to the second controller, which is connected to the second rectifier. Output of diesel generator set is connected to input of third rectifier. Electric receivers are connected to autonomous inverter. Ballast load is connected to the ballast load regulator, the first, the second and the third rectifiers, the independent inverter and the ballast load controller are connected to the DC bus.
EFFECT: technical result is higher reliability and efficiency, simplified design.
