PROJECT TITLE :
A Generalized Methodology for Dynamic Average Modeling of High-Pulse-Count Rectifiers in Transient Simulation Programs
High-pulse-count rectifier systems (with a lot of than six pulses) are usually employed in high-power applications. Dynamic average price modeling (AVM) has proven to be indispensable for simulation and analysis of such power electronic systems. However, developing correct AVMs for such line-commutated converters is difficult because of the presence of complicated switching patterns (operating modes), configuration of multi-section transformers and/or rotating machines, inter-phase transformers, filters, etc. This paper presents a generalized methodology for full-order dynamic average modeling of high-pulse-count line-commutated rectifiers, which is based on the recently proposed parametric AVM approach. Intensive simulation studies are administrated considering the eighteen-pulse rectifier example system. The accuracy and numerical blessings of the developed generalized AVM is verified against the detailed switching model, and a previously established average model in time and frequency domains.
