ELECTRIC POWER SUPPLY INSTALLATION AND PLANT CONTROL Russian patent published in 2021 - IPC H02J3/38 G01R31/371 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to controller for electric power supply installation, containing input of first level of filling, to which the first filling level of the first power accumulator of the power supply unit can be delivered. Additionally, controller comprises extra filling level input, to which additional level of filling of optional additional energy accumulator of additional installation of electric energy supply can be delivered. Additionally, controller comprises AC rated voltage determiner, which is configured to determine rated AC voltage by estimating a first filling level and/or an additional filling level. Additionally, controller comprises AC rated voltage output, from which it is possible to deliver rated voltage of alternating current to alternating current generator of electric power supply unit. Electric power supply unit comprising a controller according to the invention, a first energy accumulator, an alternating current voltage generator having a first contact input and a second contact terminal. First contact lead is connected to the first energy accumulator in electric conductivity mode. AC voltage generator is configured to generate alternating current voltage which coincides with rated AC voltage at second contact terminal. Electric power supply system comprising an electric power supply installation according to the invention and at least one additional electric power supply according to the invention, which are connected to each other in electric conductivity mode.

EFFECT: electric energy supply installation and plant control are proposed.
