Incorporation Of Self-Commutating Csc Transmission In Power System Load-Flow, Lasantha B. Perera, Y. H. Liu, N. R. Watson, J. Arrillaga
Lasantha Bernard Perera
This paper presents a method which incorporates self-commutated CSC transmission directly in a fast decoupled Newton-Raphson a.c. load flow. The d.c. equations are presented in a per unit form that is compatible with the per unit a.c. equations. A sequential method of solution is adopted in solving the load flow equations. The a.c. system equations are solved with the d.c. system modelled simply as a real and reactive power injection at the terminal busbar and for a d.c. solution, the a.c. system is modelled simply as a constant voltage at the converter a.c. terminal busbar. Further the new load flow …

Pulse Multiplication In The Self-Commutating Parallel Converter By Means Of Multi-Level Dc Voltage Reinjection, Lasantha Bernard Perera
Lasantha Bernard Perera
A multi-level dc voltage reinjection concept is described that multiplies the pulse number of the twelve-pulse dual parallel converter. The ideal reinjection waveform for complete elimination of the harmonic content is first derived, and a practical approximation is proposed which converts the standard dual converter into a sixty-pulse scheme, thus meeting the strictest harmonic standards without the assistance of filters or Pulse Width Modulation.
