METHOD OF CONTROL OF POWER OF SPACECRAFT POWER PLANT AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: spacecraft power systems using solar batteries and electric jet plasma engines, mainly stationary engines.

SUBSTANCE: proposed method includes stabilization and change of power of power plant through regulation of consumption of engine working medium. When power of solar battery drops to level of maximum permissible power consumed by engine, consumption of working medium is changed in such way that power of solar battery might change in saw-tooth pattern and vertices of saw might be in contact with line of maximum probable power of solar battery. Device proposed for realization of this method includes matching voltage converter whose outputs are connected with engine electrodes and inputs are connected with solar battery busbars, current and voltage sensors showing solar battery voltage and power sensor connected with current and voltage sensors. Comparator connected with power sensor is also connected with controllable power setter and initial power setter. Outputs of controllable power setter are connected with comparator and comparison circuit whose input is connected with power sensor output. Output of comparison circuit is connected with amplifier-regulator of consumption of working medium.

EFFECT: enhanced reliability; simplified construction and facilitated procedure of regulation of power.
