SELF-CONTAINED ELECTRIC POWER SUPPLY SYSTEM Russian patent published in 2014 - IPC H02J7/34 

FIELD: electricity.

SUBSTANCE: in the circuit there is an auxiliary synchronization and load distribution unit with data input and two data outputs and generator excitation control unit, the first output of the synchronization and load distribution unit is coupled through the generator excitation control unit to the generator control system while its second output is coupled to combustion engine control system and its input is coupled to the third auxiliary data output of the switching unit, at that the first inverter input is connected to the generator output and the first output of the switching unit is connected to the power consumer. Parallel operation of the inverter and electric generator allows solving power supply issue for burglar alarm operation at country estates, at production premises, etc. and during the period of electricity non-availability.

EFFECT: improving overload capacity of the system in off-line operation at occurrence of peak and additional loads by provision of parallel operation of the inverter and electric generator.
