CONVERTER WITH REACTIVE POWER COMPENSATION

摘要

A voltage source converter for a HVDC power transmission system is disclosed. According to one aspect, the voltage source converter includes at least one phase element having series connected diodes configured to interconnect, in use, a DC network and an AC network. The voltage source converter further includes at least one auxiliary converter configured to act as a waveform synthesizer to modify the DC voltage presented to the DC side of one or more phase elements.
