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 autonomous system of spacecraft power supply that contains a solar battery and n of accumulator battery, a voltage stabiliser coupled between the solar battery and load and n of charge and discharge devices; the method lies in control of the voltage stabiliser and charge and discharge devices depending on input and output voltage of the system, control of 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, enablement of operation 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, enablement of operation when a certain charge degree is reached by this accumulator battery, at that in case when solar batteries loose their orientation to the Sun or in case of emergency discharge of accumulator batteries operation of all discharge devices is banned (locked), and after recovery of the solar batteries orientation to the Sun and charge of the accumulator batteries up to the preset level operation of all discharge devices is unlocked.

EFFECT: improvement of the PSS reliability in case of emergencies related to unscheduled loss of solar batteries orientation to the Sun.
