METHOD TO CONTROL AUTONOMOUS SYSTEM OF GEOSTATIONARY SPACECRAFT POWER SUPPLY Russian patent published in 2014 - IPC H02J7/36 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, namely, to power supply systems (PSS) of geostationary spacecrafts (SC), using solar batteries (SB) as primary sources of energy, and energy accumulators are accumulating batteries (AB). The method is proposed to control an autonomous system of geostationary spacecraft power supply, comprising a solar battery and "n" accumulating batteries, a voltage stabiliser, connected between the solar battery and the load, and "n" charging and discharging devices, which consists in monitoring the extent of charge (discharge) of accumulating batteries, control of charging and discharging devices depending on inlet and outlet voltage of the power supply system and level of charge of accumulating batteries, prohibition for operation of the appropriate charging device, when the limit level of charge is achieved by this accumulator battery, removal of this prohibition with reduction of the level of charge to a certain value, prohibition for operation of the appropriate discharging device, when the minimum level of charge is achieved by this accumulator battery, removal of this prohibition, when a certain level of charge of this accumulating battery is achieved, at the same time the spacecraft includes an on-board computer to control condition and manage operation of the spacecraft and a command-metering radio line.

EFFECT: increased efficiency of using accumulator batteries as a geostationary SC passes through "shadow" sections of the orbit.
