Transformer-Less Series Reactive/Harmonic Compensation of Line-Commutated HVDC for Offshore Wind Power Integration

Experimental validation in addition to detailed modeling and simulation of a new transformer-less series compensator for line-commutated HVDC rectifier terminal is presented. The compensator employs very small capacitors compared to those in conventional shunt compensators or fixed series capacitors for reactive power compensation of such links. The proposed device demonstrates fundamental-frequency reactive power and harmonic-current compensation.
