摘要：
The power supply system (1) for arc furnace (2, 100) includes:
- a power converter (9) intended to be connected to a polyphase supply grid (G), and
- a polyphase transformer (10) comprising a primary circuit connected to the power converter and a secondary circuit intended to be connected to at least one electrode of the arc furnace.
The power converter comprising an input device (24), a link circuit (25) comprising a first bus (26) and a second bus (27), and an output device (28).
The power supply system further comprises a command circuit (11) configured to command the input device (24) and the output device (28) to supply the electrode and to stabilize the courant and the voltage delivered by the grid when the electrode of the arc furnace is supplied by the power supply system to reduce rejections in the grid.
