Abstract :
The detailed switch-level models of front-end diode rectifier loads can be readily implemented using a number of transient simulation programs, such as PSCAD/EMTDC, and the toolboxes in Matlab/Simulink. To improve the simulation efficiency for the system-level studies, the so-called dynamic average models have been widely used by researchers and engineers. Recently, several average-value modeling methodologies for the conventional three-phase (six-pulse) front-end rectifier loads have been discussed, and the dynamic performance of several developed models has been demonstrated in discontinuous and continuous modes. In this paper, the effects of topological variations of the ac-side filters on the system performance are investigated. Also, the steady-state and dynamic impedances predicted by the average models under balanced and unbalanced operation are compared. The studies and analyses presented here extend and complement those set forth in the preceding companion publication.
