METHOD OF CONTROL OF SPACECRAFT POWER SUPPLY SYSTEM Russian patent published in 2007 - IPC B64G1/42 B64G1/44 

FIELD: power supply for spacecraft onboard supply systems.

SUBSTANCE: proposed method includes conversion of light energy into electrical energy on board spacecraft, accumulation of electric energy by conversion into other kinds of energy and check of onboard power requirements. In addition to conversion of light energy, other kinds of energy received from outside sources are transformed into energy consumed on board aircraft. Provision is made for prediction of time intervals when consumption of electric energy exceeds amount of electrical energy converted from light energy. Kinds of consumed energy obtained from conversion of electric energy are also determined. Before beginning of passage of intervals, respective transformable kinds of energy from outside sources are accumulated. Beginning of accumulation of these kinds of energy is determined depending on consumed amount of energy and rate of accumulation of energy with change in spacecraft parameters caused by action of these kinds of energy taken into account. At predicted interval, first of all accumulated transformable kinds of energy are consumed and when necessary, energy accumulated on board spacecraft is consumed after conversion into electrical energy.

EFFECT: enhanced efficiency of energy supply system due to increased total power.
