Computer Simulation of Generator-Thyristor Networks in Power Systems

The digital computer simulation of a generator-thyristor network in power systems is described in this paper. The digital model of the synchronous generator with either controlled or uncontrolled rectifier bridge deals efficiently with the complex commutation conditions when the source impedance is significant. From the equations developed in this paper, the performance of synchronous generators with or without damper windings, connected to controlled or uncontrolled bridge rectifier loads, can be predicted from given loading data, field current, load current, generator speed, and bridge delay angle. The simulation technique is used to evaluate the performance of a salient-pole synchronous generator during both steady-state and fault conditions.
