    This paper records the development of a synchronous machine model in the mathematical form required by most modem automatic control theorems. The model is based on a new expression for the constraint imposed on the machine by a general balanced 3-phase tee-form transmission system consisting of a step-up transformer, a shunt load, and a transmission line terminating at a bus of known voltage.

    A direct current homopolar machine with liquid metal contacts can achieve high power density and efficiency. The analysis of a simple model of such a machine shows that a power density of several horsepower per pound at 90 percent efficiency is possible. The results of a design study of an experimental 280-pound 250- horsepower homopolar automotive transmission showed a 90 percent efficiency over ... View full abstract»

    A stability study of a reluctance-synchronous machine (synchronous-induction machine) is performed by applying the Nyquist stability criterion to the equations which describe the behavior of the machine during small displacements about a steady- state operating point. This investigation reveals that machine instability can occur at low speeds (low frequencies) even though balanced, constant amplit... View full abstract»

    This paper attempts the analysis of the polyphase induction machine with a slitted ferromagnetic rotor using Maxwell's field equations and concepts of equivalent permeabilities and resistivities. The analysis satisfactorily accounts for 1) physical dimensions of the slits and their number, 2) the provision of a nonmagnetic conductor, like copper in the slits, and the nature of rotor end terminatio...

    Generator capability curves, used by operating personnel in the loading of generators, are usually based upon a generator synchronous reactance equal to 1/SCR. Use of this reactance partially corrects for the effects of saturation and, while resulting in a reactive capability in error by less than 1.3 percent, produces a field excitation requirement as much as 3.8 percent lower than actual require...

    This paper attempts to present the theoretical foundations of different methods of solution developed for load flow problems in a didactic form. The load flow problem is first defined. A classification of different methods of solution is proposed. This classification consists of three groups: nodal admittance, variational, and nodal impedance matrix methods. Convergence characteristics of several ... View full abstract»

    The ability to calculate the dynamic stability limits of synchronous machines is of increasing importance today as generation and transmission equipment are being applied with higher reactances and correspondingly lower stability margins. This paper describes a digital computer program which enables the rapid computation of dynamic stability limits for a single machine connected to an infinite rec... View full abstract»

    The development and characterization of a new polyethylene insulated sodium conductor are described. The resistivity, specific gravity, and cost of sodium are compared to corresponding properties of copper and aluminum. While the alkali and alkaline earth metals have relatively good electrical conductivity, sodium was chosen because of its light weight, low cost, and availability. Physical propert...

    The protection of control and instrumentation cables in a high-voltage switchyard is becoming more essential as higher magnitudes of system voltage, load and fault currents, or overall power levels are handled. Concurrently with these increases in transient severity in the switchyard, a greater need is developing for more sophisticated control involving components more easily damaged by induced vo...
