- Abstract
The stability of a synchronous machine supplying a purely capacitive load is examined using the Root Locus technique for analysing linear systems.
The characteristic equation of the machine, including the effect of amortisseur windings, is derived, and the behaviour of the roots of the equation as the capacitive reactance varies is examined. The Root Locus technique is used to distinguish between the various zones of self-excitation, and to indicate the physical nature of the instability.
The effect of an automatic voltage regulator is included, and constraints on the parameters are developed which, in some cases, allow the regulator to prevent self-excitation from occurring.
Saturation and series resistance are included in the analysis, and the determination of the overvoltages including these factors, is achieved using an analogue computer.
The results of the investigation are confirmed by comparison with tests conducted on a laboratory 5-kVA machine.
