Abstract

This paper describes the converter model for 6/12 pulse operation and presents its applic ations for the study of the performance of converter controls. The simulation is simplified by representing the converter as a time varying equivalent circuit on the DC side which is derived on the basis of graph theory. Elimination of the need to store connection matrices and an efficient way of generating the converter equations are further innovations introduced here. The converter control based on digital techniques has been considered a long with representation of voltage dependent current order limit. The results of various test simulations considering both weak and strong ac system characteristics are represented to illustrate the simulation capability.
