A process and device are disclosed for regulating n power converter stations of a multipoint high-voltage direct current transmission network (2), wherein each station regulation (6) generates a control signal by means of a coordinated vector regulation. The extinction angle nominal value ( gamma o) of a power converter station (4) operated in the "alternating converter" mode results from the sum of a minimal extinction angle nominal value ( gamma omin) and of a generated extinction angle additional nominal value ( gamma oadd). The extinction angle additional set value ( gamma oadd) is proportional to a sensed power regulation differential value (dP) as soon as a negative or positive power regulation differential threshold value (dPu, dPo) is not reached or is exceeded. A multiterminal high-voltage direct current transmission regulation system is thus obtained which has a simple structure and a decentralised design, dispensing with an overriding master regulator and costly telecommunications installations. |
