Short-circuit currents in turbogenerators

The thesis is concerned with an investigation of several aspects of the short-circuit currents which arise in turbogenerators. Of particular interest is the phenomenon that one or more of the armature currents may not pass through zero for a considerable period following a fault at the armature terminals, so that the generator breaker may face an extremely arduous duty. Rather than employing the familiar 2-axis analysis, the numerical study in the thesis is based on a general-purpose digital phase model of the generator, since this is ideally suited to the problems investigated.
