METHOD TO CONTROL AUTONOMOUS SYSTEM OF SPACECRAFT POWER SUPPLY Russian patent published in 2014 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: invention is related to electric engineering and namely to power supply systems (PSS) of spacecraft using solar batteries as the primary energy sources and accumulator batteries as energy accumulators. The invention suggests a method for control of an autonomous system of a spacecraft power supply that contains a solar battery and n of the accumulator batteries, a voltage stabiliser coupled between the solar battery and the load and n of charge and discharge devices; the method lies in control of the voltage stabiliser and charge and discharge devices depending on the input and output voltage of the system, control of the charge and discharge degree of the accumulator batteries, prohibition of operation for the respective charge device when it reaches the charge limit of the accumulator battery, prohibition lifting when a certain discharge degree is reached by this accumulator battery, prohibition of operation for the respective discharge device when it reaches the discharge limit of the accumulator battery, prohibition lifting when a certain charge degree is reached by this accumulator battery, at that in case when the solar batteries lose their orientation to the Sun, in case of an emergency discharge of the accumulator batteries and switching-off of a part of the discharge devices when power of all the remaining discharge devices is insufficient for the load supply, operation of all devices is banned and after the recovery of the solar batteries orientation to the Sun control of the discharge devices is stopped against signals of the discharge level.

EFFECT: improved reliability of the system recovery process after emergency situations related to an unplanned deep discharge.
