Abstract :
L. F. Woodruffs One of the chief problems encountered in the calculating of the most advantageous amount and phase of compounding for the generator-end voltage of a transmission line is the determination of the settings required to locate the receiver power circle center at a predetermined point. This problem is more involved than that of finding the center of the circle for given regulator settings, and while it is possible of explicit solution, such a solution is so cumbersome and involved that it is practically useless. Yet the logical approach to the problem is to try different circles of load power until the one is found which affords most economical operation, considering line and transformer losses, synchronous reactor losses and costs, voltage rise on the line, and stability. Then, having located the circle from economic considerations, the problem becomes that of finding the regulator settings required to make this the operating circle of the system.
