Steady-State Analysis of Water Distribution Networks Including Pressure-Reducing Valves
Computer-aided Civil and Infrastructure Engineering, 2001Co-Authors: Lyes Khezzar, Saad Harous, M. BenayouneAbstract:Hydraulic networks that contain controlling elements such as pressure-reducing valves (PRVs) are difficult to simulate. Limited literature exists on the explicit modeling of PRVs in a general solution procedure for steady-State Analysis of water distribution systems. It is also known that inclusion of PRVs may lead to numerical difficulties. The objective of this article is to develop and present in sufficient detail the modeling of PRVs in combination with the linear theory method for steady-State Analysis of water distribution networks. The presentation is explicit enough and leads to a robust algorithm that can be directly implemented in a computer program. The general methodology for simulating water distribution networks that embodies graph theoretic concepts, hydraulic theory, and numerical algorithms is reviewed.

Steady-State Analysis of soft-switching converters
IEEE Transactions on Circuits and Systems I-regular Papers, 2002Co-Authors: Nicola Femia, Giulio Spagnuolo, Massimo VitelliAbstract:Steady-State Analysis of soft-switching converters is discussed in this paper. Finding the steady-State solution of soft-switching converters by means of start-up transient simulation may involve onerous computations and convergence failure, because of the mix of fast and slow natural frequencies determined respectively by the presence of soft-switching Lr-Cr cells elements and bulky L-C filter elements. The numerical method proposed in this paper shows high reliability and fast convergence, thanks to the adoption of an interval Analysis based technique for the detection of commutations and of a compensation theorem based technique for the Analysis of commutations. Some examples of steady-State Analysis of two dc-dc converters, an inverter and a power factor corrector are presented to highlight the good performances of the simulation algorithm.

Steady-State Analysis of soft-switching converters
IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2001Co-Authors: Luigi Egiziano, Giulio Spagnuolo, Nicola Femia, Massimo VitelliAbstract:Steady-State Analysis of soft-switching converters is treated in this paper. Finding the steady-State solution of soft-switching converters by means of start-up transient simulation may involve onerous computations and convergence failure because of the mix of fast and slow natural frequencies determined respectively by the presence of soft-switching Lr-Cr cells elements and bulky L-C filter elements. The numerical method proposed in this paper shows high reliability and fast convergence, thanks to the adoption of an interval Analysis-based technique for the detection of commutations and of a compensation theorem-based technique for the Analysis of commutations. An example, discussed in depth, of steady-State Analysis of a DC-DC converter is presented to highlight the good performances of the simulation algorithm.
