Abstract
The main purpose of this thesis is to simulate digitally a re representative AC/DC system. This system consists of an AC/DC converter connected to a synchronous generator at its terminals as
well as to an infinite bus-bar through a short transmission line. A group of filters is also connected at the converter AC bus-bar. The various components of the system have been analysed and re represented mathematically in the direct-phase quantities. This is because the identity of the phase currents must be retained to define the details of the successive commutation processes of the AC/DC converter.
A digital computer program is used to simulate this AC/DC system. This program is developed such as to allow the accommodation of various configurations of the system. The program has been applied study the behavior of the different components for various system arrangements. From this program, the waveforms of the different variables of the system are obtained. These waveforms are discussed to find out the effects of the generated harmonic currents of the converter station on the AC system. Particular attention has been given to their effects on the behavior of synchronous machines.
