    A new method called the step starting of induction motors has been analytically developed. Pairs of stator terminals are connected in sequence to a voltage or current pulse from a variable frequency source. The frequency of the voltage or current pulse is zero at standstill, and it is gradually increased to bring the rotor up to required speed. In this paper, it is shown that the starting torque w...

    A new method called the step starting and step running of induction motors has been analytically developed. Pairs of stator terminals are connected in sequence to a voltage or current pulse from a variable frequency source. The frequency of the voltage or current pulse is zero at standstill and is gradually increased to bring the rotor up to required speed against a given load. In part I of the pa...

  • Forces on the End Winding of Turbine-Generators I - Determination of Flux Densities

    Publication Year: 1966, Page(s):105 - 113
    Cited by:  Papers (10)

    Flux densities are determined at certain points of the end, coils (field points) of turbine-generators as a result of stator and rotor currents. Coils of the stator and rotor end windings are assumed to close through the air gap and all iron boundaries are present and assumed to have infinite permeability. Stator currents considered as sources are assumed to flow as sinusoidal current sheets on cy... View full abstract»

    Electromagnetic forces on the end coils of turbine-generators, following a 3-phase short circuit from no load, are determined for different positions of the rotor, ¿ts, in the first cycle. Forces are given by F = Il ×B. Cylindrical coordinates are used. Flux density on the field points on the coils will result from stator alternating and direct currents, rotor transient currents, and, indirectly... View full abstract»

  • The Theory of Contact-Layer Behavior under a Commutating Brush

    In this paper, the authors explain the various phases of the conduction process taking place in the commutator brush contact. At light loads and low speeds, the voltage drop in the contact layer is low (in the order of 0.5 volt). At increased loads, however, the trailing-edge voltage suddenly increases; this is a case of breakdown in the contact layer. Statistically, this is attributed to the fast... View full abstract»

  • Inductances of a Practical Slip-Ring Primitive I - An Analytical Study

    Complete inductance expressions for the windings of practical slip-ring machines are derived in terms of air-gap magnetomotive force and air-gap specific permeance. These expressions are presented in a form which facilitates verification by experiment. Deviations between the inductances of the practical and the idealized slip-ring primitive machines are-noted for a variety of winding configuration... View full abstract»

    Inductance and specific permeance measurements which were taken on a 3-kW salient-pole machine are presented. These measurements support both the inductance ratios and the absolute magnitude resulting from the derivations given in Part I of the paper. Some of the inductance measurements are performed in what is believed to be an original application of the approach of Jones and of Prescott and El-... View full abstract»

    The static behavior of torque meters, based on the principle of magnetic stress-anisotropy, has been thoroughly investigated for a device configuration suitable for incorporation in a rotating shaft without loss of accuracy. A design and operating procedure has been developed which will readily yield a device having a transfer characteristic which is reproducible and linear to within plus or minus... View full abstract»

  • Direct Method of Liapunov Applied to Transient Power System Stability

    The direct method of Liapunov is applied to the problem of power system stability. The method is first compared with the phase plane technique and equal-area criterion, with all three approaches giving identical results for the equivalent 1-machine system. A Liapunov function for the 3-machine system is developed, and conservative prediction of stability is possible if the machine velocities and a... View full abstract»

    Analysis of the stability of power systems following a transient disturbance involves the study of a large set of nonlinear differential equations. A new approach to the quantitative study of the transient stability of large power systems is presented, using the second method of Liapunov. A region of asymptotic stability for the postfault system is obtained through Liapunov theorems. If the initia... View full abstract»

    Improvement of transient stability of a 2-circuit ac transmission link by use of switched series capacitors is analyzed by equal-area diagrams for two kinds of disturbances: 1) a permanent fault on one ac circuit, cleared by opening a section of that circuit, without reclosure and 2) a permanent fault on a dc line operating in parallel with the ac line. In both cases, the aggregate megavar rating ... View full abstract»
