    The notion of the commutation cell has been introduced and used to study the local and systemic aspects of the commutation process, such as the functioning modes of a switch and the commutation mechanism. The authors show that this notion can also be a tool in a computer-aided design software, for the study and synthesis of the topologies of static converters. In this light, general laws and rules...

    The problem of electric power transmission limitations due to finite reactive resources is studied. Maximum system load, i.e., loadability, is determined using a nonlinear optimization technique (Modified Augmented Lagrangian) which accommodates limits on reactive generation as well as other practical constraints. The sensitivities of the system loadability with regard to transmission-element prim... View full abstract»

    The characteristics of a carrier-based pulse-width modulator under different modulation techniques are evaluated. Modulation with the most commonly used carrier waveforms (triangular and sawtooth waveforms) and sampling methods (uniform, double and natural sampling) is studied. In each case, the switching harmonics at the modulator output are calculated and the frequency response of the modulator ... View full abstract»

    This paper describes a microprocessor-based measuring unit which is suitable for use in high-speed digital distance relays. The unit uses an algorithm that provides accurate estimates of apparent resistance and inductance of the line in relatively short times. The algorithm deals effectively with the presence of nonfundamental frequency components in signals without making assumptions about their ... View full abstract»

  • Modelling of an autonomous power system at variable speed for transient simulation using Lagrange's laws

    The dynamical equations of a power system are usually obtained by applying the laws of electrotechnics and Newton's second law. The authors extend the use of Lagrange's laws, classically used to model mechanical systems, to the derivation of the dynamical model of an autonomous power system. One of the major advantages of the proposed approach is its simplicity, which directly derives from the uni... View full abstract»

  • Input-output-buffered broad-band packet-switch architectures with correlated input traffic

    Publication Year: 1993, Page(s):133 - 139
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1726 KB)

    The paper investigates the robustness of the nonblocking asynchronous transfer mode (ATM) switch architecture with input-output buffering and backpressure control under correlated input traffic conditions. The traffic correlation is modelled by two parameters; namely, the mean active duration of the ON-OFF source feeding each input port, and the spacing between the cells generated within an active...
