Title:
ELECTRIC POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/085177
Kind Code:
A1
Abstract:
This electric power supply device simulates a synchronous generator having a rotating body and controls the frequency of an output voltage, thereby inputting and outputting electric power to and from an electrical power grid, the electric power supply device comprising: a determination unit that determines whether an accident has occurred in the electric power grid; a command frequency output unit that, in cases where the electric power grid is normal, outputs a command frequency on the basis of a difference between a first electric power that is the target to be inputted and outputted to and from the electric power grid and a second electric power that is actually inputted and outputted to and from the electric power grid, so that the aforementioned difference is reduced, and, in cases where an accident has occurred in the electric power grid, outputs a prescribed command frequency irrespective of the difference; a generation unit that generates a control signal for controlling the output voltage on the basis of the command frequency; and a drive unit that outputs the output voltage that is generated on the basis of the control signal to the electric power grid.
