METHOD FOR REGULATING VOLTAGE OF AUTONOMOUS POWER SUPPLY SYSTEM Russian patent published in 2024 - IPC H02J9/06 

FIELD: electrical engineering.

SUBSTANCE: invention can be used in autonomous power supply systems with several diesel generator sets operating alternately, a battery pack connected in parallel to them, serving as a backup source of electrical energy and with a changing electrical load. According to the method, the voltage in the network is measured and compared with threshold values. When the voltage decreases below the first specified threshold value, the regulating device, if it was in a different mode, is switched to the mode of maintaining the maximum voltage of the generator, and subsequently the regulating device is switched to the mode of maintaining the minimum voltage of the generator, the generator control device is switched to the mode of maintaining the maximum voltage of the generator when the voltage in the electrical network drops below the first threshold value, which is measured when the maximum electrical load is turned on and the generator is disconnected from the electrical network, the maximum voltage is maintained until the next voltage measurement, when the voltage in the electrical network is exceeded network of the second threshold value, which is greater than the first voltage in the electrical network, which is measured when the maximum electrical load is turned on and the generator is disconnected from the electrical network, the generator regulating device is switched to the mode of maintaining the minimum voltage of the generator and is kept in this mode until the next voltage measurement.

EFFECT: increased service life of the battery.
