Titre : A novel power supply of online monitoring systems for power transmission lines Type de document : texte imprimé Auteurs : Lin, Du, Auteur ; Caisheng, Wang, Auteur ; Xianzhi, Li, Auteur Année de publication : 2011 Article en page(s) : pp. 2889 - 2895 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Impulse current Online monitoring system Power supply Rogowski coil Transmission line Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a novel power supply of online condition monitoring systems for power transmission lines. The proposed power supply obtains energy from the magnetic field induced by transmission-line currents using a specially designed Rogowski coil. The design details of the power supply circuit including the unit for overvoltage and impulse line current protection are given in this paper. The impact to the power supply's reliability caused by abnormal high transmission-line currents is also addressed. Experimental tests, including the short-circuit and impulse-current tests, have been conducted on the power supply to verify its performance under different operating conditions. Test results show that the power supply is capable of providing stable outputs with no saturation and low heat generation for the entire range of line conducting currents and can sustain severe conditions such as abnormal impulse currents.

Titre : Power management of a stand-alone wind/photovoltaic/fuel cell energy system Type de document : texte imprimé Auteurs : Caisheng, Wang, Auteur ; Nehrir, M.H., Auteur Année de publication : 2008 Article en page(s) : pp. 957 - 967 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Fuel cell power plants; hybrid power systems; photovoltaic power systems; power system management; wind power plants Résumé : This paper proposes an AC-linked hybrid wind/photovoltaic (PV)/fuel cell (FC) alternative energy system for stand-alone applications. Wind and PV are the primary power sources of the system, and an FC-electrolyzer combination is used as a backup and a long-term storage system. An overall power management strategy is designed for the proposed system to manage power flows among the different energy sources and the storage unit in the system. A simulation model for the hybrid energy system has been developed using MATLAB/Simulink. The system performance under different scenarios has been verified by carrying out simulation studies using a practical load demand profile and real weather data.
