SELF-CONTAINED ELECTRIC POWER SUPPLY SYSTEM Russian patent published in 2017 - IPC H02J7/34 

FIELD: electricity.

SUBSTANCE: self-contained electric power supply system contains two batteries, each of which is connected to the DC bus via a corresponding key. The batteries are connected to each other via the third key, which is connected to the charger. The first linear current sensor is mounted on a line connecting the first wind electric plant to the first rectifier, wherein the first linear current sensor is connected to the first controller which is connected to the first rectifier. The output of the diesel generator set is connected to the input of the second rectifier. The second wind electric plant is connected to the third rectifier, wherein the second linear current sensor is mounted on the line connecting them, the sensor is connected to the second controller, which is connected to the third rectifier. The electric receivers are connected to an autonomous inverter. The ballast load is connected to the ballast load regulator. The charger, the first, second and third rectifiers, an autonomous inverter, a ballast load regulator are connected to the DC bus.

EFFECT: simplified design, increased service life of batteries.
