    Methods are presented for simulating multimachine power-system dynamical response on the basis of Park's equations including the effects of an arbitrary number of circuits on the rotors of the synchronous machines. These methods allow a direct calculation treatment of effects that are neglected or treated only approximately in many power-system simulation programs, namely, amortisseur damping torq...

  • Inherent Constraints Control Convergence A New Method in the Long Look at Load Flow

    Publication Year: 1969, Page(s):22 - 27

    A new method has been devised to solve the well- known load-flow problem. It is based on the fact that the equations for real and reactive power at a bus have the same form as those for ordinary circles under the assumption that the voltages are fixed for all other buses. The real and reactive power losses are similarly expressed as circles. This enables one to find the least square solution to th... View full abstract»

  • Power System Transient Control by Capacitor Switching

    Inserting and removing a series capacitor in a transmission line can remove the oscillatory transients due to a fault. The capacitor should be inserted in the remaining transmission lines when the fault is detected and removed by short circuiting when the time rate of change of power flow through the capacitor is zero or the rate of change of phase angle between line terminations is zero. The capa... View full abstract»

    Previous work on power-line-produced telephone interference has dealt with the case of a single equivalent power conductor. This paper presents the theory applicable to a multiconductor power line excited by general, linear networks. A self-contained digital-computer program employing these techniques has been written. It rigorously handles the important case of actual communication line-power lin... View full abstract»

  • An Analytical Approach to Ferroresonance

    Ferroresonance is defined in a way corresponding to the more general expression "jump resonance." An analytical method called the incremental describing-function method is applied to the problem of ferroresonance in power systems for a certain class of problems. In general, the method is applicable when the conditions can be shown to be essentially single phase. View full abstract»

    A study of nonsustained breakdowns has been made during alternating voltage tests on the electric strength of various commercial insulants in transformer oil and compressed sulphur hexafluoride and nitrogen. Such breakdowns do not cause sustained arcing and current flow. It is demonstrated for normal test circuits, that the voltage required for nonsustained breakdown may be significantly below tha...

    A stability study of a rectifier-inverter induction motor drive system is performed by neglecting the harmonic content of the stator voltages and applying Nyquist stability criterion to the small- displacement equations obtained by linearization about an operating point. This investigation reveals that system instability can occur over a wide speed range if the system parameters are improperly sel... View full abstract»

  • A New Excitation System for Synchronous Alternators

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3557 KB)

    A new method for exciting alternators is presented. Each rotor pole of the alternator consists of two adjacent half-poles on two axes at 90 electrical degrees from each other. The resultant magnetic field can be made to revolve with respect to the rotor. This is achieved by means of a set of movable brushes around the commutator of the exciter. Investigations on the frequency and transient stabili... View full abstract»
