Abstract (en)

[origin: CN101682193A] The invention relates to a device for high-voltage direct current transmission, wherein a first converter unit (1) and a second converter unit (4) are provided, which are each connected to a main line(11, 21) and to a return line (12, 22). Each converter unit (1, 4) is connected to a separate dedicated return line (12, 22), and the return lines (12, 22) are connected to each other via a pole line(31), wherein the pole line (31) can be interrupted by a pole line interrupting unit (32). In this way, high variability in the operating modes is achieved, particularly for compensating for operational shut-offs.
