Abstract

A computer-aided modeling method, used to analyze and predict the dynamic performance of electronically rectified load-permanent magnet generator systems, is presented. These generators include multiple damping circuits. Continuous electronic switching in such systems results in a continuous change in the machine system network topologies. Hence, network modeling of such systems is done on an instantaneous basis. The natural abc frame of reference is used throughout. This is an advantage in that effects of magnetic nonlinearities, space harmonics in the MMFs, and space in the flux density waveforms as well as winding flux linkages on all machine parameters are readily taken into account. This method is applied to a two-pole, 74 kVA, 208 V, 24000 r/min permanent magnet generator, to study the generator-load system performance. Furthermore, the use of the model in studying rotor damping design options and effects of electronic component failure in the associated rectifier bridge on the generator-rectifier load system performance is given
