Abstract:
A method in a converter station for communication within a DC power transmission system including two or more interconnected converter stations includes receiving, in the converter station, a synchronization signal for synchronizing the two or more converter stations; obtaining, in the converter station, an allocation of a communication time slot; changing, in the converter station, a set-point DC voltage level during the communication time slot; and measuring, in the converter station, a change of DC current in timeslots other than the communication time slot. A communication method utilizing the DC power transmission system itself is thus provided.
