Dynamic Simulation of Airborne High Power Systems.
Abstract
This report describes work done in modeling components and in simulating AC and DC charging systems using these components. The components modeled were three phase AC generators, three phase transformers, SCR's and SCR's in AC and DC resonant charging arrays. Mathematical and circuit models were developed and simulations were conducted using SCEPTRE, a CAD program. The generator model is in terms of phase variables and allows for consideration of direct and quadrature axis damping, nonlinearities due to saturation, variation in speed and is formulated so that prime mover and control components may be added later. The transformer model is a circuit model which allows inclusion of coupling between phases and saturation effects. The SCR model is a conversion of the SPICE 2 model to a SCEPTRE model with features to account for turn-off and turn-on transients encountered in AC and DC charging applications. Simulations were conducted with the SCR models in AC and DC charging arrays. Snubbers and other compensating networks were designed to suppress undesirable transients and assure proper turn-on and turn-off. (Author)
