conclusions in this study, some characteristics that had a positive impact on the success of a manager in a hospital surge situation were identified. these characteristics ought to be taken into account when appointing hospital administrators and designing training programs for hospital administrators with the aim of being better prepared to face disasters. background hospital administrators pl...

This article first of all presents an innovative application of Real-Time Simulation Monitoring (RTSM), defined hereafter as “hydro-cloning”, developed by Power Vision Engineering. Second, a successful implementation of hydro-cloning is presented for the 170 MW La Bâtiaz hydroelectric power plant, HPP, owned and operated by Electricité d’Emosson SA, in the Canton of Wallis, Switzerland. The “Hy...

Hydraulic systems may involve both pipelines and open channels, which challenges the hydraulic transient analysis. In this paper, a method of characteristics (MOC)-finite volume (FVM) coupling has been developed with pipeline modelled using MOC channel FVM. The boundaries between these two simulation regions are based on Riemann invariants. simulated parameters can be transmitted from region to...

FMHL (Forces Motrices Hongrin-Léman SA) is the owner’s company that belongs to the shareholders Romande Energie SA, Alpiq Suisse SA, Groupe E SA and City of Lausanne. Alpiq, as owners’ representative, is in charge of the supervision of the study and the implementation of the extension project and the operator is Hydro Exploitation SA. The FMHL power plant is a 240 MW pumped-storage power plant ...

This paper introduces the indicators for surge arrester condition assessment based on the leakage current analysis. Maximum amplitude of fundamental harmonic of the resistive leakage current, maximum amplitude of third harmonic of the resistive leakage current and maximum amplitude of fundamental harmonic of the capacitive leakage current were used as indicators for surge arrester condition mon...

Computer modeling with the EMTP code has been applied to several configurations and earthing practices in use in various countries to show the effect of any differences in the dispersion (sharing) of a lightning stroke current among the available paths for the earth-seeking lightning current. Simplifying assumptions have been made to some details of the configurations to focus on the main diffe...

Dimensionless governing equations of unsteady flow and solutions for the pipeline systems having a surge tank were developed. Frequency domain pressure response expressions two widely used water supply analyzed in dimensionless frequency time domains. One is simple reservoir valve system other with pump check protected by tank. Two different developed performance was compared. The pattern imped...
