Modeling line-commutated converter HVDC transmission systems using dynamic phasors

open access: yes, 2014
This thesis develops the dynamic phasor model of a line-commutated converter (LCC) high-voltage direct current (HVDC) transmission system. The mathematical definition and properties of dynamic phasors are utilized to model both the dc-side and the ac-side of a LCC-HVDC transmission system as well as 6-pulse Graetz bridge, which is the building block of

An Accurate Impedance Model of Line Commutated Converter With Variable Commutation Overlap

IEEE Transactions on Power Delivery, 2022
This paper proposes an accurate impedance model of line commutated converter (LCC) in the stationary frame. The commutation overlap process caused by the transformer leakage inductance complicates the modeling for LCC. Traditional impedance models are derived in positive sequence and negative sequence frame based on the simplified commutation overlap ...
