Abstract :
Existing methods of representing saliency on network analysers are discussed. These include combined-reactance methods and two methods using a d.c. signal to represent the e.m.f. of the synchronous machine. A simple method of representing saliency, in association with a network-analyser generator unit, is then described, together with the associated electronic circuits. The results of a problem involving saliency, which has been solved by means of the apparatus described, are presented and the results are discussed. It is concluded that the method employed is more economical than those previously published, and is well within the normal limits of accuracy for electrical power-system analysis.
