| 摘要 |
The invention relates to a method for operating a bidirectional converter arrangement (1) either in an inverter-operating mode or in a STATCOM-operating mode, the bidirectional converter arrangement (1) comprising an AC side (3) adapted for connecting to an AC power network (7), an inverter (4) connected to the AC side (3) and to a DC side (6), the DC side (6) having a first line (8) on a first potential and a second line (8) on a second potential, the second potential being lower than the first potential, and a DC link capacitor (5) arranged at the DC side (6) and connected between the first line (8) and the second line (8), and an at least unidirectional current power semiconductor switching device (2) connected to the first line (8) and/or the second line (8) of the DC side (6) and adapted for connecting to a DC power network (9). |
