Abstract

A converter assembly for power transmission by means of high-voltage direct current has a first current-source, line-commutated converter (SRA) and a second voltage-source, self-commutated converter (SRB). The converters are d.c. series-connected to each other and are connected to an alternating-voltage network (ACN). The second converter (SRB) has control members for controlling the direct voltage (Udb) of the converter by influencing the phase position ( delta ) of the internal alternating voltage (Uvb) of the converter and hence the flow of active power between the converter and the alternating-voltage network. The control members comprise a regulator (S3, Ud-reg) for controlling the direct voltage (Udb) of the converter in dependence on the difference between on the one hand a reference value (Udbref) of the direct voltage of the converter, supplied to the control member, and on the other hand a sensed value (Udbm) of this direct voltage.
