Abstract :
The performance of displacement governors under steady-state conditions has been treated in a previous paper,1 and their behavior under transient conditions has also been discussed.2,3 In the present paper an attempt is made to investigate the transient performance of a single turbo-alternator set supplying a dead load, two sets joined by an interconnector and supplying a dead load situated between them, and a single set connected to an infinite busbar. Dynamic equations are established and from them the natural frequency of oscillations and transient stability limits are derived. Experimental work including the construction of an experimental governor and the records obtained with this governor under transient conditions is described.
