On the Power Diagram of Transmission Network

Abstract

In the Journal of A. I. E. E, Feb. 1924, M ssrs. C. L. Fortesque and C. F. Wagner have given a new method of proving the power circle diagram, maintaining therein the idea of angular displacement betwocn voltage vectors at generating and receiving ends. Adopting this idea, it is proved in the present paper that for any transmission network with two or more condensers the power diagram consists of a chain of circles, the number of circles being equal to that of condensers used.
