METHOD FOR CONTROLLING OF SPACECRAFT AUTONOMOUS POWER SUPPLY SYSTEM Russian patent published in 2016 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: invention can be applied to electrical engineering. According to method of control of autonomous spacecraft power supply system, comprising solar battery and n accumulator batteries, voltage stabilizer, connected between solar batteries and load, and n charging and discharging devices, voltage stabilizer and charge-discharge devices are controlled depending on input and output voltage of the system. Accumulator batteries' charge and discharge degree is controlled. When charge limit of accumulator battery is reached, operation of the respective charging device is banned, and this ban is canceled at the certain level of discharge of this accumulator battery. When discharge limit of accumulator battery is reached, operation of the respective discharging device is banned, and this ban is canceled at the certain level of charge of this accumulator battery. Wherein in case of loss of solar batteries' orientation to the Sun, emergency discharge of accumulator batteries operation of all discharging devices is banned (locked); after recovery of solar batteries' orientation to the Sun and charge of accumulator batteries to the specified level this ban on operation of all discharging devices is canceled. In power supply system with solar battery voltage stabilizer and additional voltage stabilization of loads of smaller nominal value from buses of the first load with series stabilized converters operation of these series stabilized converters is also locked. Wherein operating mode of charging devices of accumulator batteries is controlled, and series stabilized converters operation lock is canceled after transition of charging devices in current limitation mode.

EFFECT: increased reliability of power supply system.
