Abstract :
This paper describes the simulation approaches employed for an AC/DC/AC converter drive using SIMNON. SIMNON is a user-friendly tool for nonlinear dynamics simulation, in particular. One powerful feature is its ability of allowing integration of individual program modules after each individual module is programmed and tested independently. This particular feature is exploited here for an AC/DC/AC converter drive simulation. Two methods are used to model the rectifier and the inverter. The first method is to model each thyristor of the rectifier as an ideal switch. The second method is to approximate the dynamics of the rectifier with a set of harmonic equations. A similar approach is applied to inverter modeling. Issues related to the simulation difficulties with each model are addressed accordingly
